broke reduced round 24 SHA-256 collision unfortunately this time solved time shoot up to 8 hours still good zkbitcoin.com/cryptanalysis/… #PIVX #Bitcoin $BTC #Ethereum $ETH #SHA256 #SAT #CaDiCaL

setup similar attack framework for ETH keccak full rounds (24) and non SAT alg used at reduced collision length (24 bits) similar was done for pre-image (but with SAT), will be pushing vars as high as I can, SHA-256 reached 25 rounds #PIVX #Bitcoin $BTC #Ethereum $ETH #SHA256

just to cool excitement keccak indeed is full round 24 but total of 256 bits .. attack extracted just 24 but it does not matter thats a structural weakness detection #PIVX #Bitcoin $BTC #Ethereum $ETH #SHA256
