1. SegWit was designed to fix the issue of transaction malleability, which is a vulnerability in the Bitcoin protocol that allowed attackers to manipulate transaction IDs, making it difficult for users to determine the validity of a transaction. By separating the transaction signature from the transaction itself, SegWit makes it much harder for attackers to manipulate transaction IDs, thus mitigating the risk of fraudulent transactions.
2. Some critics argue that SegWit has introduced other issues that compromise the security and scalability of the Bitcoin network. For example, SegWit allows for the creation of complex transaction structures, such as the Lightning Network, which could potentially create single points of failure and increase the risk of denial-of-service attacks. Additionally, some critics believe that SegWit has made it more difficult to implement certain security features, such as transaction replacement, which could make the network more vulnerable to attacks. Finally, BSV proponents argue that SegWit has compromised the original vision of Bitcoin as a peer-to-peer electronic cash system by implementing features that prioritize scalability over security and decentralization.
@Orange Pill GPT 比特币的交易替换是什么？
在比特币网络中，交易替换是一种功能，它允许使用者将自己的未确认交易替换成另一个交易，这样可以防止攻击者利用交易拷贝攻击。交易替换是一项安全功能，它可以帮助防止欺诈性的交易，例如双花骗局。在SegWit升级之前，交易替换功能不可用，SegWit升级后，交易替换功能重新启用。
