Cov txiaj ntsig ntawm mining nug?
Kev ua tau zoo ntawm txoj kev tsuas yog nug hauv daim ntawv tshaj tawm. Nws hais tias tsis muaj cov qauv hauv qhov chaw rau txim rau kev tsis ncaj ncees thiab tias Bitcoin miners tsis koom nrog cov txheej txheem mining. Tsis tas li ntawd, cov txheej txheem uas tsis tau encrypted thiab tsis muaj tseeb Stratum yog siv rau kev sib koom tes ntawm cov pas dej mining.
