Staking

หาข้อมูล Validators ในปัจจุบัน

เราสามารถ stake SOL และรับ rewards สำหรับการช่วยให้ network มีความปลอดภัยมากขึ้น ในการ stake เราจะ delegate SOL ไปที่ validators ที่มีหน้าที่ประมวลผล transactions

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));
})();

สร้าง Stake Account

ทุกๆ staking instructions จะถูกควบคุมโดย Stake Program. เราจะเริ่มจากการสร้าง Stake Account ซึ่งจะถูกสร้างและ จัดการแตกต่างไปจาก system account. โดยเฉพาะอย่างยิ่งเราต้องตั้งค่า Stake Authorityและ Withdrawal Authority ของ account

Delegate Stake

เมื่อ stake account ได้รับการลงทุนแล้ว Stake Authority ก็จะสามารถ delegate ทุนนั้นไปที่ validator ได้โดยแต่ละ stake account จะสามารถ delegat ไปที่ validator เดียว โดยทุกๆ tokens ใน account จะต้อง delegated หรือ un-delegated. เมื่อ delegated แล้วจะใช้ผ่าน epochs ไปช่วงหนึ่งเพื่อที่ stake account จะอยู่ในสถานะ active

ดึงข้อมูล Delegator ด้วย Validators

Multiple accounts อาจจะ staked ไปที่ validator account ที่ใดที่หนึ่ง ในการที่จะดึงข้อมูลคน stake เราจะต้องใช้ getProgramAccounts หรือ getParsedProgramAccounts API. อ้างถึง guides section สำหรับข่อมูลเพิ่มเติม ส่วนของ stake accounts จะมีขนาด 200 bytes และ Voter Public Key จะเริ่มที่ 124 bytes.

ยกเลิก Stake

หลังจาก stake account ได้ delegated ไปแล้ว Stake Authority จะสามารถเลือกที่จะยกเลิก (deactivate) account ได้ โดยการ deactivation จะต้องเว้น epochs อยู่ระยะหนึ่งก่อนจะยกเบิกสำเร็จ และจำเป็นต้อวรอช่วงนี้ก่อนที่จะถอน SOL ออกมาได้
