Ante Library

A Node.js / TypeScript library for storing JSON data blobs on Solana blockchain and remote file storage services.

Description

This library provides functions to:

1. Store a hash of a JSON data blob on the Solana blockchain and the raw JSON data blob in a remote file storage facility such as Amazon S3, Google Cloud Storage, or Azure Blob Storage.
2. Verify if the hash of a file in remote storage equals the hash that is stored on the Solana blockchain.
3. Retrieve the contents of a file from remote storage.

Installation

npm install --save ante-library

Usage

import { AnteLibrary } from 'ante-library';

const anteLibrary = new AnteLibrary();

// Store JSON data
const jsonData = { key: 'value' };
const storageType = 's3'; // or 'google' or 'azure'
const { transactionId, filePath } = await anteLibrary.storeJsonData(jsonData, storageType);

// Verify hash
const isHashValid = await anteLibrary.verifyHash(transactionId, filePath);

// Retrieve file
const fileContents = await anteLibrary.retrieveFile(filePath, storageType);

Environment Variables

The library requires the following environment variables:

• AWS_BUCKET_NAME for Amazon S3
• GCLOUD_STORAGE_BUCKET for Google Cloud Storage
• AZURE_STORAGE_CONNECTION_STRING, AZURE_STORAGE_ACCOUNT_NAME, AZURE_STORAGE_CONTAINER_NAME for Azure Blob Storage
