Relational List of Epochs/Blocks and SVM Version on Solana
As part of my ongoing research and development efforts, I’ve encountered a specific requirement that Involves generating a relational list of epochs/block Timestamps and corresponding Machine Learning (SVM) Versions Used to Produce Those Blocks. This article provides an overview of how to achieve this in Solana.
Understanding the Problem
In Solana, Each Block/Epoch is assigned an Epoch Id and a Timestamp. The Epoch Ids are Used to Group Related Epochs Together, While Timestamps Provide Additional Context About When these Epochs occurred. However, when it comes to svm (supervised learning machine) versions, we need to know what specific algorithms were employed to train those models on the data.
Identifying SVM Versions
To Identify the SVM Version for Each Block/Epoch, We’ll Rely on Solana’s [blockchain api] ( and itss [SVM-relayed documentation] (https:/:/ /docs.solo.io/solcan/v0.12.1/docs/vm.md). Specifically, we can use the solcan package to interact with the blockchain.
Prerequisites
Before Processing, Ensure You have the Following Prerequisites installed:
Solcan: A Lightweight Node.js Cli for Interacting with Solana
YARN: A Package Manager for Managing Dependencies
Install the Required Packages:
`Bash
NPM Install -G Solcan Yarn
Relational List Generation
To create a relational list of epochs/block Timestamps and corresponding SVM Versions, We’ll use a combination of the blockchain api and data processing. The following script demonstrates how to achieve this in Solana.
`Javascript
Const {Solanaclient} = Require (‘@Solana/Web3.js’);
Const Solcan = Require (‘Solcan’);
// Initialize Solana Client
Async Function Initsolana () {
Const Solanaclient = New Solanaclient ();
Return Solanaclient;
}
// Load Data From Blockchain API
Async Function Loaddata (Solanaclient) {
// Retrieve All Blocks and Epochs From the Blockchain
Const [Allblocks, Allepochs] = Await Solanaclient.getprogram accounts ({
Accounts: [],
});
// Process Each Epoch/Block
for (const {accountid, dates} or allpochs) {
Constopochblock = data;
Const Timestamp = Epochblock.timestamp;
// Check If the Epoch/Block is Part of A SVM Group
if (epochblock.svmgroup) {
Conste SVMVersion = Epochblock.svmgroup.svmversion;
console.log (svm version: $ {svmversion} );
}
// Store Data in An Object for Easy Reference
Constepochdata = {
ID: Timestamp,
SVMVersion,
Account: Accountid, // Replace with Actual account ID
Block: Epochblock.blockid.tostring (), // Replace with Actual Block ID
};
console.log (epoch data);
}
}
// Main function to generate the relational list
ASync function main () {
Constolanaclient = Await Initsolana ();
Await load data (Solanaclient);
// to use this in a CI/CD Pipeline or Other Environments, you would like Likely Want to save the Data to a File or Database Instead of Logging It To Console
}
Main () Catch ((Error) => {
console.error (error);
});
NOTE
: This script assumes you have an account id and block id available. Replace these with actual values from your solana blockchain.
By following this guide, you should be able to creation a relational list of epochs/block Timestamps and corresponding SVM Versions on the solana blockchain.
I hope this helps! Let me know if you have any questions or need further clarification.
