I-Bitcoins ichithwa ngokufumana ezininzi iikhomputha kwihlabathi jikelele ukuzama ukujongana nomdlalo ofanayo weemathematika.
Yonke imizuzu elishumi okanye kunjalo, umntu uyasombulula i-puzzle kwaye uyavuzwa ngamanye ama-bitcoins. Emva koko, iphazili elitsha lenziwe, kwaye yonke into iqala kwakhona.
Amandla kubantu
Njengoko abantu abaninzi bafunda malunga ne-bitcoin kwaye banomdla kwiimigodi , kwaye njengoko inani le-bitcoin landa, abantu abaninzi basebenzisa iikhomputha zabo kwiimpawu zamanzi. Njengoko abantu abaninzi bajoyina inethwekhi kwaye bazama ukusombulula le puzzles, ungalindela ukuba iphazili nganye ixazululwe ngokukhawuleza, kodwa oko akukwenzeka.
Iprojekti eyenza imayini ye-bitcoin yenzelwe ukwenzela ukuba isoloko ithatha imizuzu elineshumi kuwo wonke umntu kwi-network ukuxazulula iphazili. Yenza oko ngokuhlula ubunzima bepuzzli ngokuxhomekeke ekubeni bangaphi abantu abazama ukuyicombulula.
Kuthetha ukuthini ukuba ixesha elibanjwe ukuvelisa i-bitcoin alifani - kuphela amandla okusebenzisa iikhompyutha asetyenziselwa ukuvelisa. Njengoko abantu abaninzi bajoyina inethiwekhi ye-bitcoin kwaye bazame ukufaka i-bitcoins yam, basebenzisa amandla amaninzi, kwaye ngoko ke umbane, nganye i-bitcoin iveliswe.
Ukwenza iMathe
Ubalala njani amandla ombane asetyenziselwa ukunika amandla inethiwekhi ye-bitcoin? Enye indlela yokwenza oko kukujonga ukuba zingaphi iimali eziqhutywe rhoqo kwisibini ukuxazulula iipuzzle ze-bitcoin zeemathematika, uze ufumane ukuba ungakanani amandla ombane othatha ukwenza isantya ngasinye.
Ezi zibalo zodwa zibizwa ngokuba ngumonakalo, kwaye zininzi manani zazo - eninzi, eqinisweni, kufuneka sicinge ngazo ngokwemizi yezigidi (ezibizwa ngokuba yi-megahashes) okanye iibhiliyoni zeerhesh (gigahashes) ukwenza nantoni na yabo.
Ngexesha lokubhala, iikhomputha kwi-network ye-bitcoin zenza i-342,934,450 i-Gigahashes ngesibini.
Kukho iikhompyutheni ezininzi ze-bitcoin zeemigodi apho, kodwa ezinyangeni zakutshanje, iinkampani zijolise kwiimayini ze-ASIC , ezisebenzisa amandla angaphantsi ukuqhuba izibalo. Iinkampani zemigodi eziqhuba amaninzi e-ASIC njengoko amashishini andixelele ukuba basebenzisa enye i-watt yamandla kuyo yonke i-Gigahash nganye yesibini yekhompyuter eyenziwayo xa kugcinwa imayini yamatcoins.
Kule nqanaba, inethiwekhi ye-bitcoin isebenza kwi-342934450 i-watts, elingana nama-megawatts angama-343. Izibalo ezisekelwe kwimiqulu ye-EIA ibonisa ukuba umyinge waseMelika umdla malunga ne-1.2 kilowatts yamandla, oku kuthetha ukuba ama-megawatts angama-343 aya kukwanelisa amandla angama-285,833 amakhaya ase-US ngexesha lokubhala (ngoMeyi 2015).
Oko kuninzi amandla - malunga nesithathu kwezindlu zaseSan Jose. Kwaye i-1 watt nganye yeGigahash / isibini sibalo sisebenza kakuhle. Kuza kuba nenani elikhulu labasebenzisi bokuhlala abaza kuthatha amandla amaninzi ukuqhuba abavukuzi babo. Ngoko ke mhlawumbi ukuba le ngqikelelo engalindelekanga.
Ngaphezulu kweminyaka embalwa edlulileyo, iimveliso zeendaba kunye neeblogi ziye zavelisa amanqaku amaninzi, ngeendlela eziqikelelweyo zokusetyenziswa kwamandla kagesi. Abanye bathi i-bitcoin njengokuphela kwehlabathi njengoko siyazi, ngelixa abanye becinga ukuba ingxabano epheleleyo malunga nokusetyenziswa kwamandla kwe-bitcoin yayiphelile.
Inene yonke inxulumano kuba inethwekhi ye-bitcoin inexabiso eliyimvelo njengendlela yokukhokha ekhuselekile. Yiyiphi intlawulo oyifakayo ukuba ngokusetyenziswa kwamandla kuxhomekeke ekubeni luncedo njani ukuba uya kuba kuluntu.
Ingxaki ngokuqikelela ukusetyenziswa kwamandla we-bitcoin, kwaye ngoko uyayigweba, kukuba iya kutshintsha ngexesha. Umlinganiselo wehhafu kwinethwekhi - oko kukuthi, amandla okusebenzisa iikhompyutha abantu abayichithe kuyo - sele ikhula ngokukhawuleza ngexesha elide, kwaye ithambe ukuguquguquka ngentengo ye-Bitcoin. Ukuba, njengokuba abanye bathi, i-bitcoin iphakama ngokukhawuleza kwintengo, ingaba yintoni ijezi engaphezulu?
