比特币链上的重复交易

目录

比特币链上有两个 txid 为 e3bf3d07d4b0375638d5f1db5255fe07ba2c4cb067cd81b84ee974b6585fb468 的交易。它们分别是 91722 和 91880 块的 coinbase 交易

是因为算法缺陷导致 coinbase 交易的 txid 容易重复。

后来被修复了。

BIP 30 introduced a rule that prevented blocks from containing a TXID that already exists.
BIP 34 required coinbase transactions to include the height of the block the were mining in to their transaction data.
