他的观点是:支付到比特币地址的交易,其安全性受制于哈希函数的安全性。为了让比特币地址简短,它是公钥的哈希,而非公钥本身。攻击者只需要破解哈希函数,不需要破解 ECDSA。
His point is that transactions paid to a Bitcoin Address are only as secure as the hash function. To make Bitcoin Addresses short, they are a hash of the public key, not the public key itself. An attacker would only have to break the hash function, not ECDSA.
