javascript - 为什么 bitcore-lib 无法正确解码我的比特币交易十六进制？

Question

我正在使用bitcore-lib解码以十六进制编码的交易，但我得到了一个奇怪的结果。为了进行比较，我使用了 bitcoinjs-lib它似乎工作得很好。

在这里尝试十六进制代码:https://live.blockcypher.com/btc/decodetx/

片段:

const bitcore = require('bitcore-lib')
const bitcoinjs = require('bitcoinjs-lib')

const TX_HEX = '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'

const bitcoreTx = new bitcore.Transaction(Buffer.from(TX_HEX, 'hex'))
const bitcoinjsTx = bitcoinjs.Transaction.fromHex(Buffer.from(TX_HEX, 'hex'))

console.log(bitcoreTx.toJSON())
console.log(bitcoinjsTx)

结果

bitcore(不正确)

Answer 1

您的交易是 segwit* 交易和 bitcorejs does not support it .

来自reddit :

SegWit input scriptSigs will have one of these patterns:

• 0x160014<20 bytes> (P2WPKH)
• 0x220020<32 bytes> (P2WSH)

在我看来，bitcorejs 的一个很好的替代方案是 bcoin :它具有相同的功能(运行完整 Node )以及 segwit 支持，并且具有类似的架构，因此很容易从 bitcore 迁移到它。
