Consensus

Auto共识软件包文档

一. 导言

The @autonomys/auto-consensus package provides functions for interacting with the Consensus Layer of the Autonomys Network. It allows developers to perform actions such as account management, balance inquiries, transfers, staking operations, and more. This package works hand-in-hand with @autonomys/auto-utils to simplify blockchain interactions.

Installation

Install the package via npm or yarn:

# Using npm
npm install @autonomys/auto-consensus

# Using yarn
yarn add @autonomys/auto-consensus

Importing the Package

Before using the functions provided by the auto-consensus package, you need to import them into your project:

// Import specific functions
import { balance, transfer, account } from '@autonomys/auto-consensus';

// Or import everything
import * as consensus from '@autonomys/auto-consensus';

Overview of the api Object

Many functions in the auto-consensus package require an api object as a parameter. This api object is an instance of ApiPromise from the Polkadot.js API library, which serves as the gateway to interact with the blockchain node.

Core Components of api:

• api.rpc: Methods to perform remote procedure calls to the node.
• api.query: Access to the blockchain's runtime storage.
• api.tx: Create and submit extrinsics (transactions) to the blockchain.
• api.consts: Runtime constants defined in the blockchain's metadata.
• api.events: Access to events emitted by the blockchain.
• api.types: Type definitions used by the chain.

Example:

import { createConnection } from '@autonomys/auto-utils';

async function getApiInstance() {
  const endpoint = 'wss://rpc-0.gemini-3h.subspace.network/ws';
  const api = await createConnection(endpoint);
  return api;
}

Notes

• Asynchronous Functions: Many functions return promises and should be used with await to ensure proper execution flow.

• API Disconnection: Always disconnect the API instance after your operations are complete to free up resources.

• Error Handling: Wrap your asynchronous calls in try...catch blocks to handle potential errors gracefully.
