It's notable that Colin Percival pioneered memory-hard key derivations functions with Scrypt for tarsnap. Scrypt became the proof-of-work function for asic-resistant cryptocurrencies suchs as Litecoin and influenced Ethereum's ethHash. (Besides many other applications).
In this post Colin casually speaks out against proof-of-work, without taking any credit for his significant indirect influence on it.
- pdemporg 9y agoThat is interesting - I guess by using scrypt for passwords you're encouraging crackers not to bother brute forcing (it isn't worth your time), wheras in a cryptocurrency you're actively encouraging that behaviour? Well spotted.
- cperciva 9y agoI can't exactly take credit for litecoin (and others) using scrypt, given that they did it without my knowledge, endorsement, or advice. (If they had talked to me I would have pointed out that limiting scrypt to using 1 MB of RAM eliminated the entire point of scrypt.)
