比特币钱包会随机生成一个公共地址,以及相关联的私人密钥。随机生成的公共地址必须足够“随机”,才能保证相关联的私人密钥不被猜到。

技术上说,一堆私人密钥可以和任意一个公共地址匹配,但是如果要通过暴力破解获得相互匹配的地址和密钥,就需要巨大的计算机资源遍历无数可能性。

对于任何一个单一团队来说,这显然是不可能实现的。因此LBC就希望通过其开发的一款软件,集结所有用户的计算机资源,来实现这个想法。

不过破解比特币钱包只是LBC的目标之一,另一个目标则是通过对撞攻击,让用户自己输入数据之后经过比特币地址哈希算法处理,直接生成相互匹配的密钥和地址。如果这个目标达成,那么比特币地址的生成,就必须要采用一种全新的算法。

这就和今年2月谷歌破解网页加密中的一个主要算法SHA-1,并实现世界上第一次SHA-1对撞攻击类似。曾经被广泛应用的SHA-1算法,因此而被宣告了命运的终结。

Bitcoin wallets will randomly generate a public address and associated private keys. The randomly generated public address must be "random" enough to ensure that the associated private key is not guessed.

Technically, a bunch of private keys can match any one of the public addresses, but if you want to get the matching addresses and keys through brute force, you need huge computer resources to traverse countless possibilities.

For any single team, this is clearly impossible. So LBC wants to implement this idea by developing a software that aggregates the computer resources of all users.

However, cracking the Bitcoin wallet is only one of the targets of LBC. Another target is to let users input data by themselves through collision attack. After processing by Bitcoin address hashing algorithm, the matching keys and addresses can be generated directly. If this goal is achieved, a new algorithm must be adopted to generate the bitcoin address.

This is similar to the first SHA-1 collision attack in the world that Google cracked a major algorithm in Web encryption, SHA-1, in February this year. The SHA-1 algorithm, which was widely used, was declared the end of fate.
