交易驗證失敗（錯誤執行腳本）

我在 TESTNET 上創建了一個事務，並試圖通過 BlockCyphers 工具將其推送到：

<https://live.blockcypher.com/btc-testnet/pushtx/>

當我嘗試時，我收到以下錯誤：

驗證交易時出錯：執行輸入 0 的腳本時出錯，在 0 處引用 261190892daa2c9aaaf25c20624f7f2941d2ad58dec883b0c929d1fa9306fd57：腳本未成功驗證。

這是交易。我不明白這是怎麼回事，也不確定我是否理解錯誤。誰能幫忙？

為了幫助縮小解決方案的範圍，這是我用來生成交易的程式碼：我首先生成一個接收硬幣的地址：

const btc = require('bitcoinjs-lib');
const bip39 = require('bip39');
const bip32 = require('bip32');

var mnem = 'my-12-word-bip39-seed-phrase'
var root = = bip32.fromSeed(
 bip39.mnemonicToSeedSync(mnem), bitcoin.networks.testnet
);
var p = "m/44'/1'/0'/0/0"
var pubkey = root.derivePath(p).publicKey;
var {address} = btc.payments.p2pkh({pubkey, network: btc.networks.testnet});
console.log(address);

產生mjGtZWXgPdbLUZYWtDqVTfbFieVzXFfSEj。然後我向該地址發送一些硬幣並嘗試創建我的交易：

const CS = require('coinselect');
var feeRate = 55;
var env = 'test3'
var src = 'mjGtZWXgPdbLUZYWtDqVTfbFieVzXFfSEj'
var url = `https://api.blockcypher.com/v1/btc/${env}/addrs/${src}?unspendOnly=true`;
var o = await fetch(url).then(res => res.json());
var utxos = o.txrefs.map(o => ({
   txId: o.tx_hash, 
   vout: parseInt(o.tx_output_n), 
   value: parseInt(o.value)
}));
var targets = [{address: '2N7nSZjfqikj4oVkCqaLB3CNMY3TA72PbNY', value: 500}];
var {inputs, outputs, fee} = CS(utxos, targets, feeRate);
if (ret.outputs) ret.outputs.forEach(o => {
   if (!o.address) o.address = 'msp7depXvcjLqykZxYVrWNG9QgKqLWWKEN';
})

// builds the transaction
var tx = new btc.TransactionBuilder(btc.networks.testnet);
inputs.forEach(o => tx.addInput(o.txId, o.vout));
outputs.forEach(o => tx.addOutput(o.address, o.value));
tx.sign(0, root);
console.log(tx.build().toHex());

從中我得到一個轉換為上述事務的數字字元串。可以看出，我使用相同的根來簽署用於創建源地址的交易

您的 SignatureScript 中有錯誤的公鑰：

Sig: 48-304502210093b8ff9180a8a31a5ee7b0fb6c560aef888a3d53576e530cb4601dce2d3c51da02204fd8a28743f1d1100a2f56428e743501091e833550df6cf540bad4f5248a6d3c-01

您花費的 outpoint ( 2611[...]fd57:0) 具有以下 PubkeyScript：

76-a9-14-2937902660c169b9381a5b3eb35cc889a4686a85-88-ac

當腳本執行時，它在 0x88（或 OP_EqualVerify）上失敗，因為給定公鑰 (02d7[…]d108) 的 HASH160 是e652ed9163ac72629584ec92f47602cca45aa969
