Red，谢谢你先私下告诉我！请直接发出来吧（也让大家别再提心吊胆了！）
他的意思是，付到比特币地址的交易只和哈希函数一样安全。为了让比特币地址短一些，它们是公钥的哈希，而不是公钥本身。攻击者只需要攻破哈希函数，不需要攻破 ECDSA。
英文原文
Red, thanks for telling me privately first! Please go ahead and post it (and relieve the suspense for everyone!)
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.
