To avoid users redoing work, miners hand out defined work for the users to do. Anyway this is all speculation if and until any pre-image affecting cryptanalytic attacks are found on SHA On the other hand, as Hashcash requires potentially significant computational resources to be expended on each e-mail being sent, it is somewhat difficult to tune the ideal amount of average time one wishes clients to expend computing a valid header. Hidden categories: Webarchive template wayback links Articles with short description Articles needing additional references from August All articles needing additional references All articles with unsourced statements Articles with unsourced statements from September Sister projects Essays Source.

Comment 1. But they represent hashcash bitcoin obstacles to hashacsh deployment that hashcsah to be addressed. So Scrypt's key-stretching here is not being used at all to contribute to the hardness, unlike its hashczsh use for key protection eg in deriving the encryption key from user passphrase how to bitcoin miner encrypt bitcoin wallets. A major reason scrypt was chosen was due to the perception that ASICs could not be produced for algorithms with high memory requirements. Namespaces Page Discussion.

The hashcash algorithm is relatively simple to understand. ASIC Resistance Hsshcash Bitcoin started to rise in value, it started to become understood that the most efficient way to produce the SHA hashes would be using equipment that was specially designed to hash very quickly and efficiently, called ASICs. On the other hand, as Hashcash requires potentially significant computational resources to be expended on each e-mail being sent, it is somewhat difficult to tune the ideal amount of average time one wishes clients to expend computing a valid header.
