Birthday attack example
WebBitcoin is using two hash iterations (denoted SHA256^2 ie "SHA256 function squared") and the reason for this relates to a partial attack on the smaller but related SHA1 hash. SHA1's resistance to birthday attacks has been partially broken as of 2005 in O (2^64) vs the design O (2^80). While hashcash relies on pre-image resistance and so is not ...
