Lighthouse is a permanent file storage protocol that allows the ability of perpetual storage for your files. Using Lighthouse you can store your files forever on a distributed web. Lighthouse aims to be the best entrypoint to your files on filecoin network, abstracting away all complexities and with added functionality of permanent and long term storage.

## Private Data


![encryption2.jpg](/uploads/encryption2_7fbabc718a.jpg)


Till now, most of the data stored on Filecoin and IPFS network is public that can be accessed by anyone. Hence, you can’t store files directly on a public network that are sensitive like personal photos, patient data, enterprise data, etc. This leads to developers and users hanging on to build their own encryption layer to store data on storage networks and can often lead to bad practices and over burden of access and key management. This also further leads to centralised key management for files or bad user experience to manage your own keys for files. Not to say, the trouble caused by sharing the files to authorised parties is even more problematic.


That’s why we at Lighthouse choose to build an encryption layer and access control for users to store private and sensitive data on filecoin. Using this functionality, developers need not worry about creating their own encryption layer for users and managing keys via unhealthy practices. 
 

##  How it works


Lighthouse Encryption and Access Control uses BLS threshold cryptography to ensure that any file’s decrypt key and data stays consistent and is resistant to faults and attacks. Threshold cryptography ensures that even when some parties or nodes in a system are compromised the system architecture is robust enough to keep serving users and also ensuring the data secrecy.



Furthermore, Lighthouse at no point in time receives or collects decrypt keys of any file or documents. All decrypt keys are randomly generated and fragmented from the user’s end. After which, the shards are encrypted and stored on nodes alongside user defined access conditions. 


Retrieving keys has never been easier, our architecture only required the user to sign a randomly generated message, specify the CID of the file or document to be retrieved. After which each node validates the request and access condition independently and sends a copy of the key shards they have in their possession if the access condition(s) are valid which is then aggregated on the user’s end to decrypt the file or document


##  Use Cases


This new functionality will enable variety of use cases for applications to store their private and encrypted data on Lighthouse, some of which are listed below - 


- Encrypted backup of files on Filecoin


- Storing personal photos on dweb


- Token gated applications


- DAOs can store data generated by members


- DataDAOs building collectives of data


- Restrict access to files by owners of a NFT collection


- Sensitive data like patient data can be stored


- Enterprises can store their data on a distributed web for lower cost


- Recordings for web3 meetings


- Private code repositories storage

[Lighthouse](https://www.lighthouse.storage/) is a decentralized storage protocol that utilizes the power of Filecoin and IPFS to provide perpetual storage for your files. Unlike traditional storage solutions, Lighthouse offers a number of advantages, including encryption and access control, as well as cost savings over alternatives.

![image2.png](/uploads/image2_bc79ea5e46.png)


Migrating files to Lighthouse is a relatively straightforward process, allowing you to migrate your files from any IPFS node which is on a public network, and it can be done using the CID (Content Identifier) of the files you wish to move. In this article, we will walk you through the steps of migrating both a single CID and multiple CIDs to Lighthouse.

## Steps for Migrating Using CID:
- Copy the CID of the file you want to migrate from your current storage provider.

- Go to https://files.lighthouse.storage/ and log in to the Lighthouse Files Dapp.

- Go to the Migration tab on the left side of the page.

- Click on the "Create Migration" button and paste the CID into the field provided. Press the spacebar, and then press the "Migrate CID" button.

- Wait for the CID to migrate. You can check the status of the migration in the "Status" column.

**NOTE: You can also Upload a CSV File containing a list of all the CID separated by a comma**


It's important to note that migrating your files to Lighthouse can take some time, depending on peer discoverability in the IPFS network, the size of your data, and the speed of your internet connection. However, once the migration is complete, you just created another replication of your file on the IPFS Network, also a Filecoin deal will get created for the migrated file by Lighthouse.
In conclusion, migrating your data to Lighthouse is a great way to ensure that your files are stored securely. Lighthouse is also cheaper than alternatives and provides perpetual storage. With its easy-to-use platform and simple process, you can migrate your files to Lighthouse with ease.

## Introduction
Lighthouse is now bringing decentralized storage to the entire Ocean Protocol Ecosystem. Using Lighthouse — Ocean data publishers, marketplaces, and dapps will now have access to storing data on the Filecoin network leading to net positive value generation due to the low storage cost across thousands of active miners in the filecoin economy.

## Ocean Protocol for the new data economy

![1_7HiWEKsVLrh1ezHR8Wer5w.webp](/uploads/1_7_Hi_WE_Ks_V_Lrh1ez_HR_8_Wer5w_d5feae6b05.webp)

Data is the essential resource of modern times and is the new oil. However, unlike oil, which burns and exhausts, data sharing and usage lead to more innovation and a better digital society.

Blockchain technology has enabled a new data economy which is Ocean Protocol. Ocean Protocol bridges the gap between data supply and demand, allowing data availability for the researchers and providing a fair share of revenue to the data owners. Especially in the current market scenario, we have seen companies exert tight control over data and not let anybody outside access it.

Hence, this led to closed-source ChatGPT models at OpenAI and the recent acquisition of GitHub by Microsoft, leading to AI models being controlled and developed by just a few, due to restricted access to data.

## Lighthouse — perpetual storage on Filecoin

![1_X-d6MBzNHB0kOMsDdeptpQ.webp](/uploads/1_X_d6_M_Bz_NHB_0k_O_Ms_Ddeptp_Q_db9353d9e4.webp)

Lighthouse is a perpetual storage protocol built on Filecoin that allows storing your data long-term with a one-time fee. In addition, Lighthouse Storage provides encryption and access control functionality to store private data and create token-gated access to resources. Along with fast gateways to stream 4k videos through its IPFS Gateways, Lighthouse Storage is the feature-rich way to use IPFS and Filecoin.

## Decentralized Backend Storage
Ocean Protocol provides the ability to share data through its app-level interface, like ocean marketplaces and middleware, to compute over data using a privacy-preserving method, i.e., using data without it leaving the premise of the data owners. Data owners can also keep data with a trustful entity like Ocean Protocol Foundation — a non-profit organization.

Given the presence of web3 storage systems like Filecoin, there is a demand from the Ocean Protocol ecosystem to store data there. Hence, with the support of the Ocean Protocol team, Lighthouse Storage is chosen for the integration from the Ocean Economy to Filecoin via the Decentralized Backend Storage (DBS) created by the Ocean Protocol team.

This backend (DBS) provides the following functionality

- allow users to upload content

- handle payments

- push the content to decentralized storage using Lighthouse Storage

- return the storage object to be used in the DDO

- Hence, the aim is to improve UX for the data publishers on the Ocean Protocol and provide them with ways to store their data on a decentralized network.


![1_VrGLhETjXZ_UsAHLKm1ZCQ.webp](/uploads/1_Vr_G_Lh_E_Tj_XZ_Us_AHL_Km1_ZCQ_2a03aef88d.webp)


Filecoin microservice by Lighthouse Storage registers itself to DBS, using the Register endpoint every 10 minutes per the DBS Spec. The microservice exposes the following API Endpoints:

- GetQuote — Gets a quote to store some files

- Upload — Upload some files

- GetStatus — Gets status for a job

- GetLink — Gets DDO files object for a job

## Summary
Lighthouse Storage is now integrated into the Ocean Protocol, which has led to an important piece being attached to the data economy puzzle. The Lighthouse team will continue supporting the Ocean dapps, data publishers, and marketplaces to store data on web3.

As the world is advancing towards a more decentralized web infrastructure, storage solutions such as [Lighthouse Storage](https://www.lighthouse.storage/) are becoming increasingly popular. Lighthouse Storage is a Web3 Storage Solution that allows users to store their files perpetually on Web3 using Filecoin. Lighthouse Storage can be utilized for creating a pay-to-view model, using custom contracts and NFT-based access control.

![Twitter post - 16 (1).png](/uploads/Twitter_post_16_1_df9e3f8bf5.png)

The concept of pay-to-view is not new, but with the rise of blockchain technology, it has become more feasible and secure. With Lighthouse Storage, users can upload their files with encryption, and apply access conditions to them. These access conditions can be defined using NFTs, custom contracts, time-based, or native token-based conditions. In this example, we will consider NFT-based access control.

**Step 1:**
Upload the encrypted file to the Lighthouse IPFS node. Users can choose to upload their files either using [NodeJS Encryption](https://docs.lighthouse.storage/lighthouse-1/lighthouse-sdk/code-examples/nodejs-backend/nodejs-encrypt) Upload or [ReactJS Browser Encryption](https://docs.lighthouse.storage/lighthouse-1/lighthouse-sdk/code-examples/browser-frontend/browser-with-encryption) Upload code example. Once the file is uploaded, Lighthouse node returns an IPFS CID/Hash for the encrypted file.

**Step 2:**
Apply access control to the encrypted file. Let's consider the example of NFT-based access control. The file owner can specify that only users who own NFTs from a particular collection can access the file. To do this, the owner needs to apply the access condition to the encrypted file. After applying the access condition, only the user who owns NFTs from that particular collection can access the file.

**Step 3:**
Once the access conditions have been defined, the Lighthouse view URL can be used to view the encrypted file, or the user can build a custom decryption view page using the provided [code example](https://docs.lighthouse.storage/lighthouse-1/lighthouse-sdk/code-examples/browser-frontend/decrypt-file). The user who has access to the file can pay using NFT or custom contracts. If the NFT is made a soul-bound token (SBT), the owner will not be able to transfer it to any other address, ensuring that the access is limited to the intended user.

## Introduction

Welcome to the beginner's tutorial on using the Lighthouse Python SDK for perpetual and decentralized file storage. Lighthouse is a cutting-edge file storage protocol that revolutionizes the traditional rent-based cost model of cloud storage by enabling users to pay once for their files and store them forever. With the integration of IPFS, Filecoin, and smart contracts on various blockchain networks, Lighthouse ensures data permanence, enhanced security, and cost-efficiency. This tutorial will guide you through the essential steps of leveraging the Lighthouse Python SDK to manage files perpetually on the decentralized network.

## Why Lighthouse Python SDK?

Traditional file storage models require users to periodically renew their storage subscription, leading to recurring costs and management efforts. Lighthouse Python SDK eliminates these hassles by offering a perpetual storage model, where users pay once and store files indefinitely. This innovative approach utilizes the robustness of IPFS and the storage capacity of Filecoin's miner network, guaranteeing file permanence and redundancy. Let's dive into the Lighthouse Python SDK to harness the power of perpetual decentralized file storage.

## Prerequisites

Before starting with the Lighthouse Python SDK, ensure you have the following:

1. Basic knowledge of Python programming.
2. Python installed on your computer.
3. A Lighthouse API token. If you haven't obtained one yet, sign up on the Lighthouse website to get your API token.

### **************Step 0:************** Getting your lighthouse API key [Files-Lighthouse-storage](https://files.lighthouse.storage/):

1. Go on https://files.lighthouse.storage/ and Click on Login

    ![Untitled design.png](/uploads/Untitled_design_8522f03964.png)

### **Step 1:** Install the Lighthouse Python SDK

Begin by installing the Lighthouse Python SDK via pip, allowing you to interact with the Lighthouse protocol seamlessly:

```bash
pip install lighthouseweb3
```

### **Step 2:** Import the Lighthouse Python SDK and Initialize

After installing the SDK, import the required libraries and initialize the Lighthouse client with your API token:

```python
import io
from lighthouseweb3 import Lighthouse

# Replace "YOUR_API_TOKEN" with your actual Lighthouse API token
lh = Lighthouse(token="YOUR_API_TOKEN")
```

### **Step 3:** Upload a File

Next, let's upload a file to Lighthouse. We can use the **upload** function for this purpose. We'll demonstrate both regular file upload and file upload with tags:

```python
# Regular file upload
source_file_path = "./path/to/your/file/or/directory"
upload = lh.upload(source=source_file_path)
print("Regular File Upload Successful!")

# File upload with tags
tagged_source_file_path = "./path/to/your/file/or/directory"
tag = "your_tag_name"
upload_with_tag = lh.upload(source=tagged_source_file_path, tag=tag)
print("File Upload with Tag Successful!")
```

### **Step 4:** Get Upload Information

After uploading a file, you might want to retrieve its information, such as the Content Identifier (CID). We can use the **getUploads** function for this purpose:

```python
# Replace "YOUR_CID_TO_CHECK" with the actual CID you want to check
file_cid_to_check = "YOUR_CID_TO_CHECK"
list_uploads = lh.getUploads(file_cid_to_check)
print("Upload Information:")
print(list_uploads)
```

### **Step 5:** Download a File

Now, let's download a file from Lighthouse using its CID. We'll use the **download** function to achieve this:

```python
# Replace "YOUR_CID_TO_DOWNLOAD" with the actual CID of the file you want to download
file_cid = "YOUR_CID_TO_DOWNLOAD"
destination_path = "./downloaded_file.txt"

file_info = lh.download(file_cid) # The file_info is a tuple containing the file content and its metadata

file_content = file_info[0] # Save the downloaded file to the destination path

with open(destination_path, 'wb') as destination_file:
	destination_file.write(file_content)

# The file has been successfully downloaded and saved to the destination_path
print("Download successful!")
```

### **Step 6:** Check Deal Status

Lighthouse allows you to check the status of a file's deal on the network. This can be useful to ensure that the file is accessible and replicated. Use the **getDealStatus** function to check the deal status:

```python

# Replace "YOUR_CID_TO_CHECK_STATUS" with the actual CID whose deal status you want to check
file_cid_to_check_status = "YOUR_CID_TO_CHECK_STATUS"
deal_status = lh.getDealStatus(file_cid_to_check_status)
print("Deal Status:")
print(deal_status)
```

### **Step 7:** Download Files by Tag

If you've tagged your files during the upload, you can easily retrieve them by tag using the **getTagged** function:

```python
# Replace "YOUR_TAG_TO_DOWNLOAD" with the actual tag name you want to download files for
tag_to_download = "YOUR_TAG_TO_DOWNLOAD"
downloaded_files_with_tag = lh.getTagged(tag_to_download)
print("Files Downloaded with Tag:")
print(downloaded_files_with_tag)
```

# Conclusion

Congratulations! You have successfully learned how to interact with the Lighthouse API for file upload, download, tagging, and checking deal status. You can now integrate Lighthouse into your own applications to manage files securely and efficiently. Keep exploring the Lighthouse documentation to discover more features and functionalities offered by the platform.

Remember to handle exceptions appropriately in your applications, and make sure to secure your API token to protect your data on the Lighthouse platform. Happy coding!

# **Introduction:**

Lighthouse IPNS (InterPlanetary Naming System) is a valuable tool that enables the creation of mutable pointers to content-addressed data in the IPFS (InterPlanetary File System) network. While IPFS ensures content immutability by generating unique CIDs for each piece of data, IPNS allows for regular updates to the content while retaining a consistent address. In this tutorial, we will explore two methods to publish and update content with Lighthouse IPNS: using the CLI (Command Line Interface) and Node.js. By the end of this guide, you will be able to effectively publish and manage IPNS records, making your content easily accessible and updatable.

# **Prerequisites:**

**Before we get started, ensure you have the following:**

1. Basic understanding of [IPFS](https://docs.ipfs.tech/) and [IPNS](https://docs.ipfs.tech/concepts/ipns/) concepts.
2. [Node.js](https://nodejs.org/en/download) installed on your system (for Node.js method).
3. [Lighthouse CLI](https://docs.lighthouse.storage/lighthouse-1/cli-tool/overview) installed (for CLI method).

## **Understanding Mutability in IPFS:**

In IPFS, content is typically addressed using CIDs, making it immutable. However, there are scenarios where content needs to be regularly updated, such as publishing a frequently changing website. IPNS addresses this challenge by creating mutable pointers to CIDs, known as IPNS names. These names act as links that can be updated over time while maintaining the verifiability of content addressing. Essentially, IPNS enables the sharing of a single address that can be updated to point to the new CID whenever content changes.

**How IPNS Works:**

1. **Anatomy of an IPNS Name:** An IPNS name is essentially the hash of a public key. It is associated with an IPNS record that contains various information, including the content path (/ipfs/CID) it links to, expiration details, version number, and a cryptographic signature signed by the corresponding private key. The owner of the private key can sign and publish new records at any time.
2. **IPNS Names and Content Paths:** IPNS records can point to either immutable or mutable paths. When using IPNS, the CID's meaning in the path depends on the namespace used:
    - **/ipfs/cid**: Refers to immutable content on IPFS, with the CID containing a multihash.
    - **/ipns/cid-of-libp2p-key**: Represents a mutable, cryptographic IPNS name that corresponds to a libp2p public key.

## Step 0: Getting your lighthouse API key [Files-Lighthouse-storage](https://files.lighthouse.storage/):

1. Go on https://files.lighthouse.storage/ and Click on Login

# Store and Update content on IPNS using Lighthouse:

## **Method 1: Using Lighthouse CLI**

- **Step 1:** Generate an IPNS key using the Lighthouse CLI:
    
    ```bash
    lighthouse-web3 ipns --generate-key
    ```
    
    This command will return an IPNS name and ID, which we will use later to publish the content.
    
   ![Untitled (4).png](/uploads/Untitled_4_21b432afa4.png)
    

- **Step 2:** Make a test file, text.txt:
    
    ```bash
    echo "Hello World" >> text.txt
    ```
    

- **Step 3:** Publish this file to the IPFS using [lighthouse upload](https://docs.lighthouse.storage/lighthouse-1/cli-tool/cli-commands/upload):
    
    ```bash
    lighthouse-web3 upload ./text.txt
    ```
    
    ![Untitled (5).png](/uploads/Untitled_5_52cd5e9668.png)
    

- **Step 4:** Publish the content using the generated IPNS key and the CID of the data you want to publish:
    
    ```bash
    lighthouse-web3 ipns --publish --key=8f4f116282a24cec99bcad73a317a3f4 --cid=QmWATWQ7fVPP2EFGu71UkfnqhYXDYH566qy47CnJDgvs8u
    ```
    
    You will receive a link that can be used to access the published content. This link will remain valid even if the content's IPFS hash changes.
    
    ![Untitled (6).png](/uploads/Untitled_6_b4a120c4b2.png)
    

### ****************Updating CID:****************

- Upload another file text2.txt:
    
    ```bash
    echo "Hello World2" >> text2.txt
    ```
    
- Publish this file to the IPFS using [lighthouse upload](https://docs.lighthouse.storage/lighthouse-1/cli-tool/cli-commands/upload):
    
    ```bash
    lighthouse-web3 upload ./text2.txt
    ```
    
    ![Untitled (7).png](/uploads/Untitled_7_b447b33b51.png)
    

- Update the content using the generated IPNS key and the CID of the data you want to publish:
    
    ```bash
    lighthouse-web3 ipns --publish --key=8f4f116282a24cec99bcad73a317a3f4 --cid=QmanCeGkwsaCUHaNT24ndriYTYSwZuAy4JDifdYZpHdmRa
    ```
    
    You will receive a link that can be used to access the published content. This link will remain valid even if the content's IPFS hash changes.
    

**List all IPNS** records associated with your Lighthouse account:

```bash
lighthouse-web3 ipns --list
```

This will display a list of IPNS records with their corresponding keys and CIDs.

![Untitled (8).png](/uploads/Untitled_8_ca5b79eb3f.png)

**Remove** an IPNS record:

```bash
lighthouse-web3 ipns --remove 8f4f116282a24cec99bcad73a317a3f4
```

This step allows you to remove an IPNS record if needed.

![Untitled (9).png](/uploads/Untitled_9_3d6314b401.png)

## **Method 2: Using Node.js**

**Step 0:** Get API keys from Lighthouse as explained above.

**Step 1:** Import the Lighthouse package and set up your API key:

```jsx
import lighthouse from '@lighthouse-web3/sdk';
const apiKey = process.env.API_KEY; // Replace this with your actual API key
```

**Step 2:** Generate an IPNS key using the Lighthouse SDK:

```jsx
const keyResponse = await lighthouse.generateKey(apiKey);
console.log(keyResponse.data);
```

This will return an IPNS name and ID, which we will use in the next steps.

**Step 3:** Publish the content using the generated IPNS key and the CID:

```jsx
const pubResponse = await lighthouse.publishRecord(
  "QmWC9AkGa6vSbR4yizoJrFMfmZh4XjZXxvRDknk2LdJffc",
  keyResponse.data.ipnsName,
  apiKey
);
console.log(pubResponse.data);
```

You will receive a response containing the IPNS name and the link to access the published content.

**Step 4:** Get all IPNS keys associated with your Lighthouse account:

```jsx
const allKeys = await lighthouse.getAllKeys(apiKey);
console.log(allKeys.data);
```

This step allows you to retrieve a list of all IPNS keys associated with your account.

**Step 5:** (Optional) Remove an IPNS key:

```jsx
const removeRes = await lighthouse.removeKey(keyResponse.data.ipnsName, apiKey);
console.log(removeRes.data);
```

This step enables you to remove an IPNS key if necessary.

# **Conclusion:**
Lighthouse IPNS is a powerful mechanism for publishing and updating content on the IPFS network. By combining the benefits of content-addressing with the flexibility of mutable pointers, IPNS ensures your content remains accessible and updatable. In this guide, we covered two methods to utilize Lighthouse IPNS: the CLI and Node.js. Armed with this knowledge, you can confidently publish and manage IPNS records, creating a more dynamic and user-friendly experience on the decentralized web.

## Introduction
In this tutorial, we delve into the innovative concept of Time-Lock Encryption on the InterPlanetary File System (IPFS) using Lighthouse Access Control. IPFS, often referred to as the distributed web, offers a decentralized protocol to make the web faster, p2p, and more open. On the other hand, Lighthouse.Storage is a Web3 decentralized storage solution, offering perpetual storage to store your data securely long-term.

The amalgamation of these two technologies brings forth an exciting feature – the ability to encrypt files and set conditions for their decryption based on specific blockchain parameters. One of the innovative concept it enables is "Time-Lock Encryption."

What exactly does this mean? Think of it as a time capsule. You can securely store a piece of information, and set a condition that this information will only be accessible after a particular block number on the blockchain like ethereum has been reached. Such a feature has a myriad of applications, from securing early-stage project details to establishing wills or contracts that are meant to be executed in the future.

## This tutorial will walk you through the following:

1. Preparing your environment for Lighthouse.Storage.
2. Encrypting and uploading a file onto IPFS.
3. Setting a blockchain-based time-lock condition for accessing this file on optimism chain.
4. (Optional) Retrieving the conditions set on a file.

Whether you're a blockchain enthusiast, a developer looking to integrate time-lock features, or someone curious about decentralized storage and its potential, this guide is tailored for you.

Let's embark on this journey and unlock the potential of Time-Lock Encryption on IPFS using Lighthouse Storage.

    - Initialize a new Node.js project:
        
        ```bash
        npm init -y
        ```
        
    - Install required local dependencies:
        
        ```bash
        npm install dotenv ethers
        ```
        
    1. **Security Configuration**:
    - Within your project directory, create a **.env** file.
    - Inside **.env**, add your Lighthouse API key and private key:
        
        ```makefile
        API_KEY=Your_Lighthouse_API_Key
        PRIVATE_KEY=Your_Private_Key
        ```
        
    - Always ensure your **.env** file is added to **.gitignore** to prevent exposing your credentials, especially if you're using a version control system.

    ## Step 1: Upload an Encrypted File
    
    Set up a script, **upload.js**, in your project directory. Add the following code:
    
    ```jsx
    import * as dotenv from 'dotenv';
    dotenv.config();
    import { ethers } from "ethers";
    import lighthouse from '@lighthouse-web3/sdk';
    
    const signAuthMessage = async (publicKey, privateKey) => {
      const provider = new ethers.JsonRpcProvider();
      const signer = new ethers.Wallet(privateKey, provider);
      const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
      const signedMessage = await signer.signMessage(messageRequested);
      return signedMessage;
    }
    
    const deployEncrypted = async () => {
      const path = "Absolute/path/to/your/file.txt"; // Update this path
      const apiKey = process.env.API_KEY;
      const publicKey = "Your_Public_Key"; // Update this
      const privateKey = process.env.PRIVATE_KEY;
      const signedMessage = await signAuthMessage(publicKey, privateKey);
    
      const response = await lighthouse.uploadEncrypted(
        path,
        apiKey,
        publicKey,
        signedMessage
      );
    
      console.log(response);
    }
    
    deployEncrypted();
    ```
    
    **Run the script:**
    
    ```bash
    node upload.js
    ```
    
    **Expected Response:**
    
    ```bash
    {
      data: [
        {
          Name: 'test.txt',
          Hash: 'ENCRYPTED_CID',
          Size: '58'
        }
      ]
    }
    ```
    
    ## Step 2: Apply Access Control Condition:
    
    Create a script, **access-control.js**, with the following:
    
    ```jsx
    import * as dotenv from 'dotenv';
    dotenv.config();
    import { ethers } from "ethers";
    import lighthouse from '@lighthouse-web3/sdk';
    
    const signAuthMessage = async (publicKey, privateKey) => {
      const provider = new ethers.JsonRpcProvider();
      const signer = new ethers.Wallet(privateKey, provider);
      const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
      const signedMessage = await signer.signMessage(messageRequested);
      return signedMessage;
    }
    
    const accessControl = async () => {
    	try{  
    		const cid = "Your_File_CID"; 
    		// Update this with the CID from the previous step
    		const publicKey = "Your_Public_Key"; // Update this
    	  const privateKey = process.env.PRIVATE_KEY;
    
      const conditions = [
        {
          id: 1,
          chain: "Optimism",
          method: "getBlockNumber",
    			standardContractType: "",
          returnValueTest: { comparator: ">", value: "Your_Block_Number" }, // Update this value as per your requirements
        },
      ];
    
    // Aggregator is what kind of operation to apply to access conditions
        // Suppose there are two conditions then you can apply ([1] and [2]), ([1] or [2]), !([1] and [2]).
    
      const aggregator = "([1])";
    
      const signedMessage = await signAuthMessage(publicKey, privateKey);
    
      const response = await lighthouse.applyAccessCondition(
        publicKey,
        cid,
        signedMessage,
        conditions,
        aggregator
      );
    
      console.log(response);
    }
    
    accessControl();
    
    ```
    
    **Execute the script:**
    
    ```bash
    node access-control.js
    ```
    
    **Expected Response:**
    
    ```bash
    {
      data: {
        cid: 'ENCRYPTED_CID',
        status: 'Success'
      }
    }
    ```
    
    **Note:**
    
    - Only the owner of the file can apply access conditions
    - This only works when file is uploaded with lighthouse encryption
    
    ## (Optional) Step 3: Retrieve Access Control Conditions:
    
    Formulate another script, **get-conditions.js**, as:
    
    ```jsx
    import lighthouse from '@lighthouse-web3/sdk';
    
    const accessConditions = async() => {
      const cid = "Your_File_CID"; // Update this
      const response = await lighthouse.getAccessConditions(cid);
      console.log("Condition:", response.data.conditions);
    	console.log("Response:", response)
    }
    
    accessConditions();
    ```
    
    **Run the script:**
    
    ```bash
    node get-conditions.js
    ```
    
    **Expected Response:**
    
    ```bash
    Condition: [
      {
        id: 1,
        chain: 'Optimism',
        method: 'getBlockNumber',
        standardContractType: '',
        returnValueTest: { comparator: '>', value: 'Your_Block_Number' }
      }
    ]
    Response: {
      data: {
        aggregator: '[1]',
        conditions: [ [Object] ],
        conditionsSolana: [],
        sharedTo: [],
        owner: 'Your_Public_Key',
        cid: 'ENCRYPTED_CID'
      }
    }
    ```
    
    ## (Receiver side) Step 4: Verify Access and Retrieve Encryption Key:
    
    Once you've uploaded a file and set an access control condition, before attempting to download or decrypt it, you might want to check if you have the necessary permissions (or if the conditions have been met). This step will guide you on how to do just that:
    
    **Prepare Your Script**:
    
    Create a new script named **verify-access.js** in your project directory. Insert the following code:
    
    ```jsx
    import * as dotenv from 'dotenv';
    dotenv.config();
    import { ethers } from "ethers";
    import lighthouse from '@lighthouse-web3/sdk';
    
    const signAuthMessage = async (publicKey, privateKey) => {
      const provider = new ethers.JsonRpcProvider();
      const signer = new ethers.Wallet(privateKey, provider);
      const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
      const signedMessage = await signer.signMessage(messageRequested);
      return signedMessage;
    }
    
    const getFileEncryptionKey = async () => {
      try {
        const cid = 'ENCRYPTED_CID'; // Replace with your CID
        const publicKey = 'Receiver_side_public_key'; // Replace with your public key
        const privateKey = process.env.RECEIVER_SIDE_PRIVATE_KEY;
    
        const signedMessage = await signAuthMessage(publicKey, privateKey);
    
        const keyResponse = await lighthouse.fetchEncryptionKey(
          cid,
          publicKey,
          signedMessage
        );
    
        // Print the direct response
        console.log(keyResponse);
    
      } catch (error) {
        console.log("Error:", error.message);
      }
    }
    
    getFileEncryptionKey();
    ```
    
    **Run the Script**:
    
    Execute the **verify-access.js** script:
    
    ```bash
    node verify-access.js
    ```
    
    **Expected Response (When you have access):**
    
    ```bash
    {
      data: {
        key: 'KEY'
      }
    }
    ```
    
    ****************************************Expected Response (When you do not have access):****************************************
    
    ```bash
    { message: "you don't have access", data: {} }
    ```

## Introduction to Secure File Sharing with Lighthouse SDK

In the realm of decentralized technology and applications, ensuring secure and efficient file-sharing has always been a top priority. Lighthouse, a notable player in this domain, has developed a robust SDK that aids developers in achieving this. This SDK leverages blockchain principles and IPFS, which stands for InterPlanetary File System, to ensure that files shared across networks are not only secure but also immutable and tamper-proof.

## Why is this important?

In traditional file-sharing systems, there's a central server where files are stored. This poses several challenges: from server downtimes to the risk of central point failures and vulnerabilities. IPFS and blockchain, as adopted by Lighthouse, circumvent these challenges by storing files across a network, ensuring redundancy and security.

Moreover, with the increasing emphasis on privacy and data protection regulations worldwide, tools like the Lighthouse SDK empower developers to build applications that prioritize user data security. By using encryption and decentralized storage, we can ensure that our users' files remain confidential, accessible only by intended recipients.

## What will you learn in this tutorial?

This tutorial will guide you step-by-step on how to integrate the Lighthouse SDK into your Node.js application. By the end, you'll be able to securely share encrypted files with specified recipients, leveraging Lighthouse's decentralized storage and Ethereum's robust authentication mechanisms. Whether you're a seasoned developer or just starting out in the world of decentralized apps, this guide aims to make the process straightforward and intuitive.

Let's get started by setting the foundation for our file-sharing application!

## Preparation:

### Prerequisites:

- Ensure you have Node.js installed. If not, **[download it here](https://nodejs.org/en/download/)**.

### 1. Set Up Lighthouse SDK and Wallet:

- Install the SDK globally:
    
    ```bash
    npm install -g @lighthouse-web3/sdk
    ```
    
- Generate a new Lighthouse wallet. Safeguard the provided **`Public Key`** and **`Private Key`**:
    
    ```bash
    lighthouse-web3 create-wallet
    ```
    

### 2. Project Environment Configuration:

- Create and navigate to a new directory for your endeavor:
    
    ```bash
    mkdir lighthouse-encryption && cd lighthouse-encryption
    ```
    
- Commence a new Node.js project:
    
    ```bash
    npm init -y
    ```
    
- Install the necessary local packages:
    
    ```bash
    npm install dotenv ethers
    ```
    

### 3. Enhancing Security:

- Generate a **`.env`** file within your project directory.
- Populate **`.env`** with your Lighthouse private key:
    
    ```makefile
    PRIVATE_KEY=Your_Private_Key
    ```
    
- To maintain security, add **`.env`** to your **`.gitignore`** file, especially vital if using a version control platform.

---

## Implementation:

### **1. Setting the Groundwork:**

Within your project directory:

- Construct a file named **`fileSharing.js`**.

### **2. Import and Initialization:**

In **`fileSharing.js`**, write:

```jsx
import * as dotenv from 'dotenv';
dotenv.config();
import { ethers } from "ethers";
import lighthouse from '@lighthouse-web3/sdk';
```

### **3. Message Signing Function:**

This helper function will assist in the authentication process:

```jsx
const signAuthMessage = async (publicKey, privateKey) => {
  const provider = new ethers.JsonRpcProvider();
  const signer = new ethers.Wallet(privateKey, provider);
  const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
  const signedMessage = await signer.signMessage(messageRequested);
  return signedMessage;
}
```

### **4. File Sharing Procedure:**

Implement the function to handle file sharing via Lighthouse SDK

*To ensure clarity and simplicity, let's break down the file sharing procedure into three distinct points:*

### **4.1 Initialize Variables:**

Set up the fundamental variables required for our function. Each variable holds specific data crucial for the operation:

```jsx
const cid = "QmS2NzycJoA7De33qMWwqyE2w3BL1i396qfwZiHBb1KuZh";
// CID: Unique identifier for content on IPFS.

const publicKey = "0x5D62F371206306F1ebd4573803F70772f1153186";
// PublicKey: Your Lighthouse identity.

const privateKey = process.env.PRIVATE_KEY;
// PrivateKey: Secured key for authentication, stored away from the codebase.

const receiverPublicKey = ["0xea447D81825282D3ec02772f1ab045ec6227F3e4"];
// ReceiverPublicKey: Intended recipient's Lighthouse identity.

```

### **4.2 Authenticate and Sign the Message:**

With our variables set, the next step is to authenticate our actions by signing the message:

```jsx
const signedMessage = await signAuthMessage(publicKey, privateKey);
// SignedMessage: A verified authentication message for security.
```

### **4.3 Share the File:**

Having our signed message and our initialized variables, we're ready to share our encrypted file securely:

```jsx
const shareResponse = await lighthouse.shareFile(
  publicKey,
  receiverPublicKey,
  cid,
  signedMessage
);
// ShareFile: Lighthouse function to securely share your file.

console.log(shareResponse);
// ResponseOutput: Shows the result of the file-sharing action.

// To view the shared file, navigate to:
// https://files.lighthouse.storage/viewFile/<cid>
```

In the event of an error or an issue during this process, the catch block will capture and display it for our reference:

```jsx
} catch (error) {
    console.log(error);
}
```

Lastly, initiate the function:

```jsx
shareFile();
```

### **Full Code for Secure File Sharing using Lighthouse SDK:**

```jsx
import * as dotenv from 'dotenv';
dotenv.config();
import { ethers } from "ethers";
import lighthouse from '@lighthouse-web3/sdk';

const signAuthMessage = async (publicKey, privateKey) => {
  const provider = new ethers.JsonRpcProvider();
  const signer = new ethers.Wallet(privateKey, provider);
  const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
  const signedMessage = await signer.signMessage(messageRequested);
  return signedMessage;
};

const shareFile = async () => {
  try {
    const cid = "QmS2NzycJoA7De33qMWwqyE2w3BL1i396qfwZiHBb1KuZh";
    // CID: Unique identifier for content on IPFS.

    const publicKey = "0x5D62F371206306F1ebd4573803F70772f1153186";
    // PublicKey: Your Lighthouse identity.

    const privateKey = process.env.PRIVATE_KEY;
    // PrivateKey: Secured key for authentication, stored away from the codebase.

    const signedMessage = await signAuthMessage(publicKey, privateKey);
    // SignedMessage: A verified authentication message for security.

    const receiverPublicKey = ["0xea447D81825282D3ec02772f1ab045ec6227F3e4"];
    // ReceiverPublicKey: Intended recipient's Lighthouse identity.

    const shareResponse = await lighthouse.shareFile(
      publicKey,
      receiverPublicKey,
      cid,
      signedMessage
    );
    // ShareFile: Lighthouse function to securely share your file.

    console.log(shareResponse);
    // ResponseOutput: Shows the result of the file-sharing action.

    // Navigate to view the shared file:
    // https://files.lighthouse.storage/viewFile/<cid>
  } catch (error) {
    console.log(error);
  }
};

shareFile();
```

### **5. Running the Script:**

Execute the script:

```bash
node fileSharing.js
```

Observe the file-sharing response and ensure you can access the CID link to validate the secure file sharing.

## Wrap-Up:

Congratulations! You've adeptly shared an encrypted file using the Lighthouse SDK. Always prioritize the security of your private and API keys.

# **Introduction**

In the realm of decentralized applications (dApps), user authentication remains a critical aspect. Traditional methods often rely on centralized servers, which can be a point of vulnerability. Enter Passkey: a decentralized authentication method that leverages the power of WebAuthn and Ethereum.

**What is Passkey?**

Passkey is a concept where users can authenticate themselves using cryptographic keys instead of traditional usernames and passwords. By integrating WebAuthn, a web standard for secure authentication, with Ethereum, a decentralized blockchain platform, Passkey offers a robust and secure authentication mechanism for dApps.

In this guide, we'll walk you through creating a demo app that showcases this integration using `create-react-app`.

## Use cases

Before jumping onto the tutorial, let us look at some use cases for a passkey type encryption on the decentralized web. **The use cases ranges all the way from:**

- Decentralized Social Media
- DeFi Applications
- Healthcare Record Management

**To more general application like:**

- Website and Application Authentication
- Multi-Factor Authentication (MFA)
- Secure Document Access

Basically anything that needs frequent signing for authentication can make use of Lighthouse Passkey authentication. 

### **Prerequisites**

Ensure you have Node.js and npm installed. If not, download and install them from [Node.js official website](https://nodejs.org/).

### **Setting Up**

1. First, let's create a new React app:

```bash
npx create-react-app passkey-demo
cd passkey-demo
```

1. Install the necessary packages:

```bash
npm install axios
```

### **Utility Functions**

These functions will aid in the authentication process:

1. **Fetching Authentication Message**

```jsx
const getAuthMessage = async (address) => {
  try {
    const data = await axios
      .get(`https://encryption.lighthouse.storage/api/message/${address}`, {
        headers: {
          "Content-Type": "application/json",
        },
      })
      .then((res) => res.data[0].message);
    return { message: data, error: null };
  } catch (err) {
    return { message: null, error: err?.response?.data || err.message };
  }
};
```

1. **Buffer and Base64 Conversions**

```jsx
function bufferToBase64url(buffer) {
  const byteView = new Uint8Array(buffer);
  let str = "";
  for (const charCode of byteView) {
    str += String.fromCharCode(charCode);
  }

  // Binary string to base64
  const base64String = btoa(str);

  // Base64 to base64url
  // We assume that the base64url string is well-formed.
  const base64urlString = base64String
    ?.replace(/\+/g, "-")
    ?.replace(/\//g, "_")
    ?.replace(/=/g, "");
  return base64urlString;
}

function base64urlToBuffer(base64url) {
  let binary = atob(base64url?.replace(/_/g, "/")?.replace(/-/g, "+"));
  let length = binary.length;
  let buffer = new Uint8Array(length);

  for (let i = 0; i < length; i++) {
    buffer[i] = binary.charCodeAt(i);
  }

  return buffer;
}

```

1. **Transforming Public Key**

```jsx
function transformPublicKey(publicKey) {
  const selected_key_index = 0;
  let transformedPublicKey = {
    ...publicKey,
    challenge: new Uint8Array([...publicKey.challenge.data]),
    allowCredentials: [
      {
        type: "public-key",
        id: base64urlToBuffer(
          publicKey.allowCredentials[selected_key_index]?.credentialID
        ),
      },
    ],
  };

  return [
    transformedPublicKey,
    publicKey.allowCredentials[selected_key_index]?.credentialID,
  ];
}

```

### **The Main App**

Our main React component will handle user interactions:

```jsx
import React, { useState } from "react";
import axios from "axios";
import "./App.css";

function App() {
  // State variables for account, error, chain ID, keys, and token
  const [account, setAccount] = useState("");
  const [error, setError] = useState("");
  const [chainId, setChainId] = useState("");
  const [keys, setKeys] = useState({});
  const [token, setToken] = useState("");

  // Function to connect to the Ethereum wallet
  const connectWallet = async () => {
    if (window.ethereum) {
      try {
        // Request account access
        const accounts = await window.ethereum.request({
          method: "eth_requestAccounts",
        });
        setAccount(accounts[0]);
        const chainId = await window.ethereum.request({
          method: "eth_chainId",
        });
        setChainId(chainId);
      } catch (error) {
        console.error("User denied account access");
      }
    } else {
      console.error("Ethereum provider not detected");
    }
  };

  // Function to disconnect from the Ethereum wallet
  const disconnect = () => {
    setAccount("");
    setChainId("");
  };

  // Function to sign a message using the Ethereum wallet
  const signMessage = async (message) => {
    try {
      const signature = await window.ethereum.request({
        method: "personal_sign",
        params: [account, message],
      });
      return signature;
    } catch (error) {
      setError(error.toString());
    }
  };

  // Convert account to lowercase for uniformity
  const username = account.toLowerCase();

  // Function to login using Passkey
  const login = async () => {
    try {
      const startResponse = await axios.post(
        "https://encryption.lighthouse.storage/passkey/login/start",
        {
          address: username,
        }
      );
      const publicKey = startResponse.data;
      const [transformedPublicKey, credentialID] = transformPublicKey(publicKey);

      // Get credentials using WebAuthn
      const credential = await navigator.credentials.get({
        publicKey: transformedPublicKey,
      });

      // Convert credential to a format suitable for the backend
      const serializeable = {
        authenticatorAttachment: credential.authenticatorAttachment,
        id: credential.id,
        rawId: bufferToBase64url(credential.rawId),
        response: {
          attestationObject: bufferToBase64url(credential.response.attestationObject),
          clientDataJSON: bufferToBase64url(credential.response.clientDataJSON),
          signature: bufferToBase64url(credential.response.signature),
          authenticatorData: bufferToBase64url(credential.response.authenticatorData),
        },
        type: credential.type,
      };

      const finishResponse = await axios.post(
        "https://encryption.lighthouse.storage/passkey/login/finish",
        {
          credentialID,
          data: credential,
        }
      );
      const token = finishResponse.data.token;
      setToken(token);
      if (token) {
        alert("Successfully authenticated using webAuthn");
      }
    } catch (error) {
      console.error("Error during login:", error);
    }
  };

  // Function to register using Passkey
  const register = async () => {
    try {
      const { message } = await getAuthMessage(account.toLowerCase());

This permanent ownership-based file storage will help store users' valuable data, including NFT metadata. Lighthouse also supports the deployment of smart contracts on **Filecoin Virtual Machine (FVM), Solana, Polygon, and more.**
Lighthouse's perpetual protocol operates along with a smart contract-powered endowment pool to pay storage providers. When someone pays to store a file, a portion of that fund is distributed to the Filecoin network's storage providers, and the remaining fund is distributed to the endowment pool.

**Features of Lighthouse**

__The major features of Lighthouse include:__

- Permanent Storage: Lighthouse allows users to pay once and own the storage space indefinitely. This feature eliminates the pain of subscription model payment options available with the traditional Web2 storage solutions. 

- Image Optimization: Users have the flexibility to fix the height and width of their stored images while retrieving them from the IPFS. This image optimization option helps users save bandwidth, allowing more storage choices. 
- Payment Flexibility: Lighthouse allows users to pay with any tokens from popular blockchain networks like Ethereum, Solana, Optimism, and Polygon, to name a few. This multi-chain support allows users to integrate with supported dApps. 
- Zero Lock-in: Users don't need to face difficulties associated with any constraints associated with specific storage providers. For this reason, you can always access and manage your data 24/7.
- Lower Cost: Lighthouse offers low-cost storage solutions by leveraging the open market of Filecoin miners who earn block rewards from its network.
- Encryption and Privacy: The user's data are secured efficiently using encryption technology. Moreover, files are stored in fragments to protect the privacy of their file's content.
-  Fast File Retrievals: The availability of Lighthouse's custom IPFS gateway helps you retrieve your files faster. This feature is applicable to low and high-size files like high-resolution video files. 

**Conclusion** 

There is a growing demand for data storage that needs to be addressed properly. The traditional Web2 storage provider fails to offer its users cost-efficient, secure, and privacy-ensured solutions. 

The development of Web3 storage solutions emerges to solve the issues faced by Web2 storage. Lighthouse utilizes the potential of IPFS and Filecoin to deliver permanent storage spaces for users for lower fees.

Imagine a world where your data stays safe forever without you having to lift a finger. No more reminders to renew your storage deals, no more panicking about lost files. Welcome to perpetual storage with Lighthouse, powered by the Filecoin Network.
In this blog, we're diving deep into the world of the Endowment Pool. We'll cover everything from what it is to how it works and why it's the future of data storage. 
So, grab a coffee, and let's dive in!

### A Revolution in Data Storage

Before we get into what the endowment pool is all about, let's set the stage with the Filecoin Network. Filecoin isn’t just any storage network; it’s the superhero of decentralized storage. With over 12 EiB (exbibytes, if you’re wondering) of storage capacity, Filecoin has quickly become the go-to network for storing humanity’s most valuable information.
Filecoin is more than just a vast storage network; it’s a revolution in how we store and access data. Traditional storage solutions often rely on centralized servers, which can be vulnerable to hacks, outages, and data manipulation. 
Filecoin flips this model by leveraging a decentralized approach, distributing data across a global network of storage providers. This not only enhances security but also ensures that data is stored in a redundant, highly reliable manner.

### The Global Community of Storage Providers

One of the key strengths of Filecoin is its extensive community of over 3500 storage providers worldwide. These providers range from small individual operators to large-scale data centers, all contributing to the network's impressive storage capacity. 
By joining this network, they’re not just storing data; they’re part of a larger mission to preserve humanity’s most important information. This community-driven approach means that data is spread across multiple locations, reducing the risk of loss and ensuring greater resilience.

## Why Reinvent the Wheel When Filecoin is Already Rolling Strong?
Why start from scratch when Filecoin is already a well-oiled machine with 3500+ storage providers globally? That’s why Lighthouse is built on this rock-solid network. 
Filecoin’s Proof of Replication (PoR) and Proof of Space-Time (PoST) ensure your data is stored uniquely and continuously, making it the perfect partner for perpetual storage.

### Proof of Replication is Like a Fingerprint for Your Data

In the Filecoin network, Proof of Replication (PoR) ensures that storage miners hold a unique copy of your data. It’s like having a fingerprint for your files, ensuring no two are identical. 
This proof happens once when the data is initially stored, but its importance is monumental. PoR ensures no sneaky miner stores multiple copies of your data in the same space, keeping everything transparent and verifiable.

### Proof of Space-Time is the Marathon Runner of Data Storage

While PoR is a one-time thing, Proof of Space-Time (PoST) is the marathon runner, continuously proving that miners dedicate space to your data over time. Miners must regularly demonstrate their commitment by passing PoST checks, ensuring your data remains safe and sound. 
Fail these checks, and miners face penalties. This ongoing verification is crucial for maintaining the integrity of perpetual storage on Lighthouse.

## Meet the Endowment Pool, Your Data’s Financial Guardian Angel

Now, let’s talk about one of the most important components of the whole architecture, the Endowment Pool. Imagine Marcus Aurelius, the ancient Roman Emperor, creating the first endowment for philosophy studies in Athens. Fast forward to today, and Lighthouse uses a similar concept to sustain long-term data storage.

![2.jpg](/uploads/2_86a6fa0a6c.jpg)

### How the Endowment Pool Works 
The Endowment Pool is a clever mechanism that ensures your data is stored forever without any additional effort on your part. 
Here’s how it works, step-by-step:

1. Initial Payment: When you pay to store your data on Lighthouse, your payment is divided into two parts. A small portion of the payment goes directly to the storage providers who will physically store your data on the Filecoin network for a limited period. This covers the immediate cost of storage.

2. Funding the Pool: The majority of your payment goes into the Endowment Pool. This pool is a financial reservoir designed to sustain your data storage indefinitely. It's like setting up a trust fund for your data, where the principal amount is invested wisely to generate continuous returns.

3. Investment and Growth: The funds in the Endowment Pool don’t just sit idle. They are actively invested to grow over time. Here’s how:

   3.1 DeFi Protocols: A significant portion of the funds can be lent out in decentralized finance (DeFi) protocols to earn interest.Stablecoins like USDC, USDT, and DAI are typically used for these investments to minimize risk and ensure steady returns.

   3.2 Filecoin Staking and Lending: Another part of the funds is held in Filecoin (FIL). These FIL tokens can be staked or lent to storage miners, earning additional rewards and yield. This dual strategy balances the pool's exposure to FIL price fluctuations while maximizing growth.

4. Continuous Funding: The Endowment Pool periodically releases funds to pay for the ongoing storage costs. This is where the magic happens:

   4.1 Smart Contracts: The pool operates using smart contracts on the Filecoin Virtual Machine (FVM). These smart contracts automatically manage the release of funds based on predefined conditions and schedules.

   4.2.Automated Payments: Funds are distributed regularly to storage providers, ensuring that your data storage fees are covered without any manual effort. When data deals expire, funds are automatically transferred to service providers to renew the deals. This seamless process keeps your storage updated, giving you lifetime data storage without the hassle.

5. Dynamic Management: The pool’s composition and investment strategies are dynamically managed to adapt to changing market conditions. This includes adjusting the proportion of funds allocated to different investment avenues and responding to fluctuations in the cost of storage or the returns on investments.


By leveraging smart contracts and sophisticated financial strategies, the Endowment Pool ensures that your data remains safely stored on the Filecoin network indefinitely. This innovative approach not only secures your data but also frees you from the hassle of manual renewals and the risk of data loss. It's a set-it-and-forget-it solution for perpetual data storage.

### The Formula for Data Perpetuity
The sustainability of the endowment pool hinges on a simple formula:
![3.png](/uploads/3_b78b4da743.png)
![unnamed.png](/uploads/unnamed_346f5ae6e7.png)

In essence, the rewards from the pool must always be greater than or equal to the cost of storing the data for the specified time. This formula ensures the perpetual storage of your data, making it financially sustainable.


### Master and Custom Pools Tailored to Your Needs
Lighthouse offers flexibility with its endowment pools. 
![4.jpg](/uploads/4_474150b7dc.jpg)

The Master Pool is the default, overseen initially by the Lighthouse team and eventually governed by a DAO. This pool will be deployed across multiple chains for easy access.
Custom Pools allow for specialized storage needs. Want a pool dedicated to NFT data? Done. Need a pool for blockchain state data? You got it. These custom pools can be funded and controlled by specific communities or DAOs, offering tailored storage solutions with various risk levels.

### Governance & Growth for a Bright Future
As the endowment pool grows, its governance becomes crucial. Proposals can be made to decide the pool’s composition, investment strategies, and even fund public goods like DeSci initiatives. Transparency is key, with the endowment pool’s reserves and projections available on the blockchain, ensuring trust and accountability.

### The Replication Worker is Your Data’s Bodyguard
Lighthouse doesn’t just rely on storage providers to keep your data safe. Enter the Replication Worker, a vigilant service that monitors storage deals and ensures data replications as requested by clients. 
If a storage provider drops your data, the Replication Worker triggers a deal repair, creating new storage deals to maintain the initial number of replications. It’s like having a dedicated bodyguard for your data, ensuring it’s always safe and sound.


### Transparency & Accountability with Smart Contracts
One of the standout features of the endowment pool is its transparency. Thanks to EVM-based smart contracts, every transaction, every yield, and every reserve is visible on the blockchain. 
This transparency isn’t just about trust; it’s about giving users a clear picture of how their funds are being used and how long their data can be sustained. It’s like having a crystal-clear ledger that anyone can audit at any time.
### Beyond Storage, the Potential for Public Good
The endowment pool’s potential doesn’t stop at storage. If the pool grows significantly, surplus funds could be used to support public goods. Imagine funding decentralized science (DeSci) projects, maintaining open-source software, or supporting other community-driven initiatives. 
The governance mechanisms in place allow for such decisions, ensuring that the benefits of the pool extend beyond just storage.
### What Happens if the Pool Dries Up
While the endowment pool is designed to be sustainable, there’s always the question of what happens if the funds run low. In such a scenario, clients might be required to top up the pool. 
Governance proposals can also address how to manage such situations, ensuring that there’s always a plan B.
### Final Thoughts
In a nutshell, the endowment pool on the Filecoin Network is not just a storage solution; it’s a revolution in how we think about data preservation. With Lighthouse at the helm, your data isn’t just stored – it’s immortalized. 
So, say goodbye to storage renewals and hello to the future of perpetual data storage.


Discover How the Endowment Pool Makes Your Data Immortal

Imagine a world where you can analyze sensitive data without ever decrypting it. Sounds like science fiction, right? But it's not—it's the magic of Homomorphic Encryption. 
This groundbreaking technology allows computations on encrypted data, preserving privacy while extracting valuable insights.
Let’s dive deep into how this works and how Lighthouse Storage is venturing into this fascinating domain with Fully Homomorphic Encryption (FHE).
### The Encryption Conundrum: Why Traditional Methods Aren’t Enough
Encryption is the bedrock of data security, ensuring that your sensitive information stays hidden from prying eyes. But here’s the catch: traditional encryption only protects data when it’s at rest (stored) or in transit (being sent somewhere). As soon as you need to process or analyze that data, you have to decrypt it, exposing it to potential risks.
Imagine handing over the keys to your treasure chest just because you need someone to count the gold inside. It’s a vulnerability that businesses, especially those handling sensitive information, have had to live with—until now.
These traditional encryption methods, while robust, fall short when applied to the unique challenges of blockchain and AI.
 Let's break down why:
1. Vulnerability During Data Processing:
Traditional encryption methods protect data at rest (when stored) and in transit (when being transferred). However, as soon as you need to process or analyze the data—whether it's running computations on it or training AI models—you have to decrypt it. 
This decryption process exposes the data to potential breaches. In a blockchain environment, where transparency and immutability are key, this exposure is especially problematic. The moment the data is decrypted, it's vulnerable to attacks from within the network, undermining the very security blockchain aims to provide.
2. Incompatibility with Decentralized Systems:
Blockchains are decentralized, meaning data is stored and processed across multiple nodes. Traditional encryption methods, designed for centralized systems, struggle to adapt to this environment. 
When data is decrypted for processing on a blockchain, it becomes visible to all nodes, increasing the risk of unauthorized access. This is particularly concerning when dealing with sensitive datasets, such as financial information or personal data, where privacy is paramount.
3. Challenges in Secure AI Model Training:
Training AI models requires vast amounts of data, often involving personal or proprietary information. Traditional encryption methods necessitate decrypting this data during training, leaving it exposed. 
On blockchain, this exposure is even more dangerous due to the distributed nature of the network. If any node in the network is compromised, the entire dataset could be at risk. This makes it difficult to ensure the privacy and security of the data used in AI training.
4. Lack of Scalability:
Traditional encryption methods were not designed with the scale of blockchain in mind. As the amount of data stored and processed on the blockchain increases, so does the risk. 
Decrypting and re-encrypting large volumes of data can be time-consuming and resource-intensive, slowing down the entire system. This lack of scalability is a significant hurdle for blockchain applications that require the secure handling of large datasets, such as AI training.

### Homomorphic Encryption Keeps Secrets While Doing the Math. But How?
Imagine needing to perform complex calculations on your most sensitive data—think customer financial records, medical histories, or proprietary algorithms—without ever having to unlock it from its secure vault. That's the promise of Homomorphic Encryption (HE).
Homomorphic Encryption allows you to perform computations directly on encrypted data, yielding results that are identical to what you'd get if the data were decrypted. It's as if you hired a vault master who could count your gold, weigh it, and even divide it into piles, all without ever opening the chest. The gold stays safe inside, untouched and unseen, but you still get the precise outcome you need.

### How is it different?
While traditional encryption methods lock up your data and throw away the key until you need to use it, Homomorphic Encryption keeps the key safely hidden, even during processing. But not all Homomorphic Encryption is created equal.
There are mainly 3 forms of HE, each with its own capabilities:
- **Partial Homomorphic Encryption (PHE)**: Allows only a specific type of operation (like addition or multiplication) on encrypted data, but not both.
- **Somewhat Homomorphic Encryption (SHE)**: Supports a limited number of operations before it needs to be decrypted.
These methods, while useful in certain contexts, are still limited. They can't handle the full complexity of operations required by modern applications like machine learning, where data often needs to undergo numerous and varied computations.
But Fully Homomorphic Encryption (FHE) allows for any type of computation on encrypted data, no matter how complex. Whether you're running machine learning algorithms, conducting data analytics, or even facilitating secure electronic voting, FHE can process it all without ever exposing the underlying data.

### What Makes FHE so EPIC?
- End-to-End Security in AI: AI model training often requires vast amounts of sensitive data. With FHE, you can train these models directly on encrypted datasets. The data never needs to be decrypted, ensuring that personal information, trade secrets, or proprietary algorithms are never exposed, even during intensive computational processes. 

- Complex Computations, Zero Exposure: FHE enables you to perform intricate operations, like training AI models or running advanced analytics, without decrypting the data. This is especially critical in blockchain applications, where data is distributed across multiple nodes and must remain secure at all times. 

- Enabling Trustless Computation: One of the core principles of blockchain is the concept of trustless transactions—where participants don’t need to trust one another because the system itself guarantees security. FHE takes this a step further by enabling trustless computation. Even in decentralized environments where nodes may not fully trust each other, FHE ensures that data can be processed without being exposed, preserving the integrity and confidentiality of the information.

- Future-Proofing Against Quantum Threats: As quantum computing advances, the security of traditional encryption methods is increasingly at risk. FHE, with its advanced cryptographic techniques, offers a layer of protection that is more resistant to these emerging threats. By allowing computations on encrypted data, FHE reduces the risk of exposure, even in a quantum world.

- Privacy-Preserving Data Sharing: FHE makes it possible to share encrypted data with third parties for processing without ever revealing the underlying information. This is particularly valuable in industries like finance, where institutions need to collaborate on data without compromising privacy. 

### Are There Any Real-World Applications of FHE?
Well, there is a whole FHE ecosystem out there.
Fully Homomorphic Encryption (FHE) is quickly becoming a cornerstone of privacy-focused innovations, and a vibrant ecosystem is emerging around this technology.

- SunscreenTech: Known for their FHE compilers, SunscreenTech is making it easier for developers to implement FHE in their applications.
- zkHoldem: Using FHE to make on-chain gambling secure, zkHoldem is blending privacy with entertainment on blockchain platforms.
These companies are not just building tools—they’re crafting the future of privacy in a decentralized world. 
The FHE ecosystem is rapidly expanding, with innovations in general-purpose FHE blockchains, hardware acceleration, and specialized applications like private voting and confidential ERC20 tokens.

### Why Should You Care About Homomorphic Encryption? (No, Really)
Homomorphic Encryption isn't just a technical marvel—it's a transformative technology with real-world implications that touch every aspect of data security and privacy. 
Here's why it matters to you:
1. **Enhanced Privacy: Your Data Stays Safe, Always**
Traditional encryption methods are effective at keeping your data safe when it's stored (at rest) or being transmitted (in transit). However, the moment you need to use that data, whether for analysis, processing, or anything else, it must be decrypted, exposing it to potential risks. With Homomorphic Encryption, your data remains encrypted throughout its entire lifecycle, including during computation. This means that even while performing operations on your data, it stays protected, drastically reducing the risk of exposure.
For instance, if you're handling sensitive financial information or personal medical records, Homomorphic Encryption ensures that this data is never exposed, not even to those performing the computations. This enhanced privacy is crucial in an era where data breaches and privacy violations are increasingly common.
2. **Secure Collaboration: Trust Without Compromise**
Sharing data with third parties, whether cloud providers, business partners, or research institutions, has always been a double-edged sword. On one hand, collaboration is necessary for innovation and efficiency. On the other, sharing data often means compromising its security, as it typically requires decryption at some stage.
Homomorphic Encryption changes the game by allowing you to share encrypted data that can still be processed by the third party. The cloud provider or partner can perform the necessary computations on the data without ever seeing the raw, unencrypted information. This secure collaboration means that you can take advantage of cloud computing's scalability and processing power without sacrificing privacy.
Imagine a scenario where multiple organizations need to collaborate on a sensitive research project. With Homomorphic Encryption, they can share encrypted data and run joint analyses without ever exposing their confidential data to one another. This fosters collaboration while maintaining strict privacy controls.
3. **Unlocking AI & ML Potential using FHE**
Artificial Intelligence (AI) and Machine Learning (ML) thrive on data, but when that data is sensitive, like patient records, financial transactions, or proprietary algorithms, there's always a tension between using the data and keeping it secure. Homomorphic Encryption resolves this tension by allowing AI and ML models to be trained on encrypted datasets.
This means you can unlock the full potential of AI and ML without ever exposing sensitive information. For instance, a healthcare provider could use Homomorphic Encryption to analyze encrypted patient data for predictive analytics or personalized treatment plans, ensuring that patient privacy is never compromised.
Moreover, companies can collaborate on AI projects by sharing encrypted data and models, allowing them to innovate together without risking data breaches. This capability is especially crucial in sectors like finance, healthcare, and cybersecurity, where the integrity and confidentiality of data are paramount.
### How Does Lighthouse Come Into This?
Now, here’s where it gets even more interesting. 
We at [Lighthouse Storage](https://www.lighthouse.storage/) are exploring the integration of Fully Homomorphic Encryption into its platform. But why?
We aim to enable our users to store and process large encrypted datasets securely, making it perfect for AI startups, financial institutions, and healthcare organizations. 

![image4.png](/uploads/image4_0f026f0ec7.png)

By leveraging FHE, Lighthouse can offer:
- Encrypted Data Processing: Allowing computations on stored data without ever decrypting it, ensuring that privacy is never compromised.


- Secure Sharing: Collaborate across untrusted domains without the risk of data exposure.


- Regulatory Adherence: Meet the highest standards of data privacy laws by keeping sensitive data encrypted, even during processing.

### But Why Isn’t Homomorphic Encryption Everywhere Yet?

If Homomorphic Encryption (HE) is so powerful, why isn’t it the standard everywhere? 
The short answer: it’s complicated. 
Despite its incredible potential, there are several significant challenges that have prevented HE—especially Fully Homomorphic Encryption (FHE)—from becoming ubiquitous.
1. **Computational Cost**:
FHE is computationally intensive. It requires vast amounts of processing power and time, making it slower and more expensive compared to traditional encryption methods. This high computational cost has been a significant barrier to widespread adoption, particularly for applications that require real-time processing.

2. **Noise Accumulation**:
One of the technical challenges with HE is the accumulation of noise during computations. Each operation on encrypted data introduces a small amount of noise. Over time, this noise can build up, potentially corrupting the results and making the data unusable. While bootstrapping techniques can clean up this noise, they add additional computational overhead, further slowing down the process.

3. **Complexity**:
Implementing and maintaining HE systems is not straightforward. The mathematics behind HE is complex, requiring specialized knowledge to implement effectively. This complexity increases the risk of errors, making it more challenging to develop robust and secure HE solutions.

4. **Limited Practical Implementations**:
Although FHE can theoretically support any computation on encrypted data, practical implementations have been limited to simpler operations or require substantial simplifications. This limitation means that many use cases are still beyond the reach of current FHE technology.

### Remedies and Ongoing Research
Despite these challenges, the field of HE is rapidly advancing, with researchers and innovators working on several promising solutions:
- Trusted Execution Environments (TEEs):
TEEs provide a secure area within a processor where computations can be performed safely, even in potentially compromised environments. By combining HE with TEEs, it’s possible to offload some of the computational burden while maintaining strong security guarantees.

- Improved Algorithms:
Advances in HE algorithms, such as more efficient noise management techniques and optimized encryption schemes, are helping to reduce the computational overhead. These improvements are making HE more practical for a broader range of applications.

- Hardware Acceleration:
Specialized hardware, such as FHE-specific coprocessors or GPUs, can significantly speed up HE operations. Companies like Optalysys and Cysic are developing hardware solutions designed to accelerate FHE computations, making them more feasible for real-world applications.

Noise Reduction Techniques:
Researchers are exploring new methods to manage and reduce noise accumulation in HE systems. Techniques like TFHE, CKKS, and BGV are being developed to strike a balance between noise tolerance and computational efficiency, making HE more reliable and scalable.

- Layered HE Architectures:
By using a combination of different HE types, such as PHE, SHE, and FHE, it’s possible to create layered encryption schemes that optimize performance for specific use cases. For instance, PHE or SHE might be used for less sensitive operations, with FHE reserved for critical computations.

#### Final Thoughts
While Homomorphic Encryption isn’t yet a silver bullet for all privacy challenges, the progress being made is encouraging. As computational costs decrease and noise management improves, we can expect HE, especially FHE to play an increasingly vital role in securing sensitive data. The integration of HE with technologies like TEEs and hardware acceleration will further enhance its practicality, paving the way for broader adoption across industries.
The future of data privacy may well be homomorphic, and as the technology continues to evolve, the dream of secure, private computations without compromising performance is steadily becoming a reality. 
The future of privacy is bright, and with innovators like Lighthouse leading the charge, we’re well on our way to a world where data is always protected, even when it’s in use.

The buzz around AI and blockchain is louder than ever, with industries scrambling to understand how these technologies can transform their operations. But as with any hype train, it's crucial to differentiate between genuine innovation and flashy gimmicks. 
So, what exactly happens when these two tech giants collide? Let's break down the intersection between AI and blockchain, uncover the myths, and explore the genuine potential of this dynamic duo.
### Blockchain Creates Trust & AI Needs Trust
The idea that blockchain could combat misinformation generated by AI sounds compelling. Imagine a world where every piece of digital content is authenticated and verified using an immutable ledger. This would seemingly create a utopia where misinformation is kept at bay, and digital truth is preserved. But before we get carried away, let’s dive deeper into how feasible this actually is.
[https://x.com/Polkadot/status/1782514882249703756
](https://x.com/Polkadot/status/1782514882249703756)

### Blockchain’s Role in Timestamping
Blockchain's main strength lies in its ability to create a permanent, tamper-proof record of transactions. For example, if I upload a photo of a flying saucer above the Washington Monument and register this image on the Ethereum blockchain, the blockchain will timestamp this event. This means we can see that the photo was registered before a specific block number, in this case, block 20,000,000.
Advantages of Timestamping
- Immutable Record: The blockchain provides an immutable record of when and by whom the content was created. This is useful for verifying the timeline of digital content.
- Proof of Existence: By storing a hash of the image on the blockchain, you can prove that the image existed at a certain point in time. This helps in proving ownership and original creation.

The Limitation of Authenticity Verification

While blockchain is excellent at providing a timestamp and proof of existence, it falls short when it comes to verifying the content's authenticity. Here’s why:
1. Content Verification:
- What the Blockchain Can’t Tell: Blockchain can't verify whether a photo is genuine or manipulated. The ledger can tell us when I registered the image, but it can't determine if the photo was created by a camera, edited with Photoshop, or generated by AI.
- No Insight into the Creation Process: The blockchain does not offer any insight into how the image was created or whether it has been altered. It only confirms that I registered it, but not the nature of its authenticity.

While blockchain can confirm when and by whom a digital asset was created, it does not solve the problem of content authenticity. The immutable nature of blockchain is a powerful tool for timestamps and proof of existence but falls short in verifying the truthfulness of the content itself.

### Is Blockchain The Guardian of Privacy for AI?
The narrative that blockchain can provide privacy for AI, especially in model training, is another area ripe for scrutiny. The concept is that blockchain’s decentralized and transparent nature could somehow secure sensitive data involved in training AI models. 
But is this a feasible solution or just a misunderstanding of blockchain’s capabilities?

](https://x.com/hosseeb/status/1773146428594090473)

### Blockchain’s Transparency vs. Privacy Needs
Blockchain’s core feature is its transparency. Every transaction on the blockchain is visible to all participants in the network, which is great for ensuring data integrity but problematic for privacy.
Transparency vs. Confidentiality:
- Public Ledger: In a public blockchain, every transaction is recorded on a ledger that is accessible to anyone. This transparency is fundamental to how blockchains operate, but it doesn’t align with the need for privacy in model training.
- Privacy Concerns: When training AI models, especially with sensitive data (e.g., medical records), maintaining confidentiality is crucial. Blockchain’s transparency can conflict with the need to keep this data private.

Privacy-Enhancing Technologies:

While blockchain itself is not suited for privacy, several advanced cryptographic techniques can address these needs. However, these technologies are not inherently part of blockchain systems:
1. Zero-Knowledge Proofs (ZKPs):
- How ZKPs Work: Zero-Knowledge Proofs allow one party to prove to another that they know a value without revealing the value itself. This is useful for confirming transactions without disclosing details but doesn’t solve privacy issues for model training directly.
- Limitations for AI: ZKPs can’t obscure the data used to train AI models. They can prove that a transaction or computation was performed correctly, but they don’t keep the data used for training confidential.
- Organizations Involved: Companies like Zcash, and Peanut Protocol are actively working on ZKP technologies.
![image11.gif](/uploads/image11_ac8ef7bba6.gif)


2. Fully Homomorphic Encryption (FHE):
- What FHE Does: Fully Homomorphic Encryption allows computations to be performed on encrypted data without needing to decrypt it first. This means AI models can be trained on encrypted data without ever exposing the raw data.
- Challenges with FHE: While promising, FHE is computationally intensive and has not yet been widely adopted due to performance constraints and complexity.
- Organizations Involved: Chalink & Zama are working on bringing FHE onchain.

![image10.jpg](/uploads/image10_205d21dba1.jpg)

3. Secure Multi-Party Computation (MPC):
- What MPC Achieves: Secure Multi-Party Computation enables multiple parties to jointly compute a function over their inputs while keeping those inputs private. This can be used for privacy-preserving AI, allowing model training without exposing individual data points.
- Adoption and Complexity: Like FHE, MPC is complex and not yet widely implemented in practical systems.
- Organizations Involved: Companies such as Lighthouse and startups like Partisia are advancing MPC technologies for privacy-preserving computations.

### AI Bots with Blockchain Wallets: How Does That Work?
Jeremy Allaire, CEO of Circle, has suggested that AI and blockchain are a perfect pairing, particularly for bots using cryptocurrency. On the surface, this sounds like a win-win. After all, cryptocurrencies and AI both thrive in digital spaces. However, there’s a darker side to this union.
Imagine AI bots wielding crypto to make autonomous transactions. This could mean bots making decisions about financial transactions with real-world consequences. My own research in 2015 explored how smart contracts on Ethereum could facilitate crime if combined with AI. Imagine a rogue AI creating smart contracts that pay bounties for illicit activities. 
While this scenario isn’t a reality yet, it’s a future risk that needs serious consideration. Blockchain enthusiasts and AI developers must prioritize safety measures to prevent such scenarios.
Real Use Cases and Emerging Technologies
