Staking

该模块使基于 Cosmos SDK 的区块链能够支持高级权益证明（PoS）系统。在此系统中，链的原生质押代币持有者可以成为验证者，并可以将代币委托给验证者，最终确定系统的有效验证者集。

​

消息

让我们探索（并提供示例）Staking 模块导出的消息，我们可以使用这些消息与 Injective 链交互。

​

MsgBeginRedelegate

此消息用于将已质押的 INJ 从一个验证者重新委托到另一个验证者。

import { Network } from "@injectivelabs/networks";
import { toChainFormat } from "@injectivelabs/utils";
import { MsgBroadcasterWithPk } from "@injectivelabs/sdk-ts/core/tx";
import { MsgBeginRedelegate } from "@injectivelabs/sdk-ts/core/modules";

const denom = "inj";
const privateKey = "0x...";
const amount = toChainFormat(5);
const injectiveAddress = "inj1...";
const sourceValidatorAddress = "inj1...";
const destinationValidatorAddress = "inj1...";

const msg = MsgBeginRedelegate.fromJSON({
  injectiveAddress,
  dstValidatorAddress: destinationValidatorAddress,
  srcValidatorAddress: sourceValidatorAddress,
  amount: {
    denom,
    amount,
  },
});

const txHash = await new MsgBroadcasterWithPk({
  privateKey,
  network: Network.Testnet,
}).broadcast({
  msgs: msg,
});

console.log(txHash);

​

MsgDelegate

此消息用于将 INJ 委托给验证者。

import { Network } from "@injectivelabs/networks";
import { toChainFormat } from "@injectivelabs/utils";
import { MsgDelegate } from "@injectivelabs/sdk-ts/core/modules";
import { MsgBroadcasterWithPk } from "@injectivelabs/sdk-ts/core/tx";

const denom = "inj";
const privateKey = "0x...";
const injectiveAddress = "inj1...";
const validatorAddress = "inj1...";
const amount = toChainFormat(5).toFixed();

const msg = MsgDelegate.fromJSON({
  injectiveAddress,
  validatorAddress,
  amount: {
    denom,
    amount,
  },
});

const txHash = await new MsgBroadcasterWithPk({
  privateKey,
  network: Network.Testnet,
}).broadcast({
  msgs: msg,
});

console.log(txHash);

​

MsgCancelUnbondingDelegation

此消息用于取消从验证者解绑，重置绑定期，并重新委托给之前的验证者。

import { Network } from "@injectivelabs/networks";
import { toChainFormat } from "@injectivelabs/utils";
import { MsgBroadcasterWithPk } from "@injectivelabs/sdk-ts/core/tx";
import { MsgCancelUnbondingDelegation } from "@injectivelabs/sdk-ts/core/modules";

const denom = "inj";
const delegatorAddress = "inj1...";
const privateKey = "0x...";
const amount = toChainFormat(5).toFixed();
const validatorAddress = "inj1...";
const creationHeight = "123456"; // 发起解绑时的区块高度

const msg = MsgCancelUnbondingDelegation.fromJSON({
  delegatorAddress,
  validatorAddress,
  amount: {
    denom,
    amount,
  },
  creationHeight,
});

const txHash = await new MsgBroadcasterWithPk({
  privateKey,
  network: Network.Testnet,
}).broadcast({
  msgs: msg,
});

console.log(txHash);
