Staking

Get Current Validators

우리는 네트워크를 안정적으로 확보하는 것을 돕기 위해 SOL을 스테이킹할 수 있고 보성을 얻을 수 있습니다. 스테이킹을 위해서 우리는 차례로 transaction들을 처리하는 validator들에게 SOL을 위임해야 합니다.

import { clusterApiUrl, Connection } from "@solana/web3.js";

(async () => {
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  // Get all validators, categorized by current (i.e. active) and deliquent (i.e. inactive)
  const { current, delinquent } = await connection.getVoteAccounts();
  console.log("current validators: ", current);
  console.log("all validators: ", current.concat(delinquent));
})();

Create Stake Account

모든 스테이킹 Instruction들은 Stake Program에 의해 다뤄집니다. 시작하기 위해 우리는 system account 표준과는 다르게 생성되고 관리되는 Stake Account를 생성합니다. 특별하게, 우리는 Account의 Stake Authority와 Withdrawal Authority를 설정해야 합니다.

Delegate Stake

일단 Stake Account에 자금이 적립된다면, Stake Authority가 validator에게 자금을 위임할 수 있습니다. 각 Stake Account는 오직 한 번에 한 validator에게만 위임될 수 있습니다. 추가로, 해당 Account에 있는 모든 Token들이 위임되거나 위임되지 않아야 합니다. 위임되고 나서 Stake Account가 활성화되기 위해서는 몇 에포크가 걸립니다.

다수의 Account들이 특정 Validator Account에 스테이킹 했을지 모릅니다. 우리는 모든 스테이커들을 조회하기 위해 getProgramAccounts 또는 getParsedProgramAccounts API를 사용할 것입니다. 더 많은 정보는 guides section를 참조하세요. Stake Account들은 200 bytes 길이 정도고 Voter Public Key는 124 bytes부터 입니다. Reference

Deactivate Stake

Stake Account가 위임된 후에 언제든 Stake Authority가 그 Account를 비활성화시킬 수 있습니다. 비활성화는 완료되기까지 몇 에포크가 걸리고, SOL 출금 전에 비활성화가 먼저 요구됩니다.
