ASIC alebo GPU? Panelisti na Consensus ponúkajú svoj pohľad na vec
Aktualizované
Na newyorskom summite Consensus v pondelok prebehla zaujímavá diskusia o kladoch a záporoch dvoch kategórií ťažobných zariadení: ASIC (Application Specific Integrated Circuit) a GPU (Graphics Processing Unit). Kým prvé zariadenie ponúka vysokú efektivitu výpočtov pri ťažbe bitcoinu a niekoľkých ďalších kryptomien, grafické karty sú pre bežných ľudí dostupnejšie (najťaženejšou kryptomenou na GPUs je Ethereum).
Debata medzi predstaviteľmi kryptomenového ťažobného priemyslu sa tak stočila na problém technologickej bezpečnosti (vysokého hashrate) vs. decentralizácie. Marco Streng, CEO spoločnosti Genesis Mining, tak zdôraznil úlohu grafických kariet: „GPUs sú najviac decentralizovaný ťažobný hardvér na planéte.“ Gideon Powell, CEO spoločnosti Autonomous Crypto Corp, oponoval: „Vlády môžu napadnúť algoritmy vyťažiteľné na GPUs pomocou útoku 51 percent. To by pri bitcoine bolo veľmi ťažko realizovateľné.“
Často kritizovaným aspektom zariadenia ASIC je dominantné postavenie čínskej firmy Bitmain v ich produkcii – táto firma má odhadovaný trhový podiel v rade 70 – 80 percent. V posledných mesiacoch sa o toto odvetvie však začala zaujímať aj firma Samsung.
