V uplynulých dňoch bola zverejnená stránka crypto51, ktorá prepočítava nákladnosť tzv. 51 % útoku. Tento útok umožňuje útočníkovi disponujúcemu aspoň 51 % hashratom pri danom coine vykonávať tzv. double spendy, meniť históriu transakcií a cenzurovať nové transakcie. V uplynulých týždňoch bol menovaný typ útoku použitý v sieti kryptomena Verge, Bitcoin Gold a Mona Coin. Pri útokoch boli okrem iného podvedené kryptomenové burzy, ktoré prišli pri útoku na Bitcoin Gold až o 18 miliónov dolárov.

Podľa stránky crypto51 je nákladnosť útoku na niektoré menšie projekty veľmi nízka, pohybujúca sa v rádoch jednotiek až desiatok dolárov za jednu hodinu útoku. Hashrate k útoku si možno totiž pohodlne prenajať skrz stránky NiceHash.
