Abavukuzi be-bitcoin abanamandla aphezulu kanye nama-semiconductors esizukulwane esilandelayo bayahambisana futhi njengoba ubuchwepheshe be-process node bukhula, i-SHA256 hashrate iyalandela.Umbiko wezimayini wakamuva we-Coinshares waminyaka yonke wezimayini uqokomisa ukuthi izinsimbi ezisanda kwethulwa zezimayini “zinomthamo ophindwe ka-5 we-hashrate ngeyunithi ngayinye njengabanduleli bazo bokukhiqiza.”Ubuchwepheshe be-chip obuthuthukisiwe bukhule ngokungaphezi futhi buqiniswa kakhulu ukukhiqizwa kwedivayisi ye-ASIC.Ngaphezu kwalokho, izindaba ezivela ku-International Electron Devices Meeting (IEDM) obanjwe ngoDisemba 7-11 zibonisa ukuthi imboni ye-semiconductor ihamba ngaphezu kwezinqubo ze-7nm, 5nm, kanye ne-3nm futhi ilindele ukuklama ama-chips angu-2nm, kanye no-1.4 nm ngo-2029.

I-Bitcoin Mining Rigs ka-2019 Ikhiqiza I-Hashrate Eningi Kakhulu Kunamamodeli Onyaka Odlule

Ngokuqondene nemboni yezimayini bitcoin, imboni yokukhiqiza idivayisi ye-ASIC ikhula ngokushesha.Imishini yanamuhla ikhiqiza i-hashrate eningi kakhulu kunemishini yezimayini eyakhiqizwa eminyakeni edlule futhi eminingana yayo ikhiqiza ama-hashpower amaningi kakhulu kunawamamodeli angonyaka odlule.I-Coinshares Research ishicilele umbiko kuleli sonto ogqamisa ukuthi izinsimbi zezimayini zanamuhla zine "5x i-hashrate ngeyunithi ngayinye" uma kuqhathaniswa namayunithi esizukulwane sangaphambili akhiqizwa.I-News.Bitcoin.com ihlanganise ama-hashrate akhuphukayo ngeyunithi ngayinye kusukela kumadivayisi athengiswa ngo-2018 futhi ukwanda kwe-hashrate ngo-2019 kuye kwaba namandla.Isibonelo, ngo-2017-2018 izinsimbi eziningi zezimayini zishintshile zisuka ezingeni le-16nm semiconductor zaya ezinqubweni eziphansi ze-12nm, 10nm kanye ne-7nm.Ngomhla ka-27 Disemba 2018, imishini yezimayini ephezulu ye-bitcoin ikhiqize isilinganiso se-44 terahash ngomzuzwana (TH / s).Imishini ka-2018 ephezulu yayihlanganisa i-Ebang Ebit E11+ (44TH/s), i-Innosilicon's Terminator 2 (25TH/s), i-Bitmain's Antminer S15 (28TH/s) kanye ne-Microbt Whatsminer M10 (33TH/s).

NgoZibandlela wezi-2019, inani lemishini yezimayini manje likhiqiza i-50TH/s kuya ku-73TH/s.Kukhona izinsimbi zezimayini ezinamandla aphezulu njenge-Bitmain's Antminer S17+ (73TH/s), kanye namamodeli we-S17 50TH/s-53TH/s.I-Innosilicon ine-Terminator 3, ethi ikhiqiza amandla angu-52TH/s kanye no-2800W wamandla odongeni.Bese kuba nezinsimbi ezifana ne-Strongu STU-U8 Pro (60TH/s), i-Microbt Whatsminer M20S (68TH/s) kanye ne-Bitmain's Antminer T17+ (64TH/s).Ezintengo zanamuhla kanye nezindleko zikagesi ezilinganiselwa ku-$0.12 nge-kilowatt-hora (kWh), zonke lezi zixhobo zezimayini ezinamandla amakhulu zenza inzuzo uma zemba amanethiwekhi e-SHA256 e-BTC noma i-BCH.Ekupheleni kombiko wezimayini zoCwaningo lwe-Coinshares, ucwaningo luxoxa ngabavukuzi abaningi besizukulwane esilandelayo abatholakalayo, eceleni kwemishini emidala ethengiswa ezimakethe zesibili noma esasetshenziswa nanamuhla.Umbiko uhlanganisa ukuhanjiswa kwemishini nezintengo ezivela kubakhiqizi abafana ne-Bitfury, Bitmain, Canaan ne-Ebang.Umkhiqizo ngamunye wezimayini unikezwa “Amandla Okulinganisa Okuqagela ukusuka ku-0 – 10,” kuphawula umbiko.

Ngenkathi abavukuzi be-Bitcoin Besebenzisa i-7nm kuya ku-12nm Chips, Abakhiqizi Be-Semiconductor Banomdwebo Womgwaqo we-2nm kanye ne-1.4nm Izinqubo

Ngaphezu kokwenyuka kokusebenza okuphawulekayo ngezinsimbi zezimayini zango-2019 uma kuqhathaniswa namamodeli akhiqizwa ngonyaka odlule, umcimbi wakamuva we-IEDM wemboni ye-semiconductor ubonisa ukuthi abavukuzi be-ASIC cishe bazoqhubeka nokuthuthuka njengoba iminyaka iqhubeka.Le ngqungquthela yezinsuku ezinhlanu igcizelele ukukhula kwezinqubo ze-7nm, 5nm, kanye ne-3nm embonini, kodwa kukhona okusha okusendleleni.Amaslayidi avela ku-Intel, ongomunye wabakhiqizi abaphezulu be-semiconductor emhlabeni, abonisa ukuthi inkampani ihlela ukusheshisa izinqubo zayo ze-10nm ne-7nm futhi ilindele ukuba ne-node engu-1.4nm ngo-2029. Kuleli sonto kukhulunywe okokuqala ngengqalasizinda engu-1.4nm ku-Intel i-slide ne-anandtech.com ithi indawo “izolingana nama-athomu ayi-silicon ayi-12 ngaphesheya.”Umbukiso wesilayidi womcimbi we-IEDM ovela ku-Intel futhi ukhombisa i-node engu-5nm ka-2023 kanye ne-2nm node phakathi nesikhathi esibekelwe isikhathi sika-2029.

Njengamanje izinsimbi zezimayini ze-ASIC ezikhiqizwe abakhiqizi abafana ne-Bitmain, i-Canaan, i-Ebang, ne-Microbt ikakhulukazi zisebenzisa ama-chips angu-12nm, 10nm, kanye ne-7nm.Amayunithi ka-2019 asebenzisa lawa maships akhiqiza ngaphezulu kuka-50TH/s kuya ku-73TH/s ngeyunithi ngayinye.Lokhu kusho ukuthi njengoba izinqubo ze-5nm ne-3nm ziqina eminyakeni emibili ezayo, imishini yezimayini kufanele ithuthuke kakhulu.Kunzima ukucabanga ukuthi izinsimbi zezimayini ezipakishwe nge-2nm kanye ne-1.4 nm chips zizosebenza kanjani, kodwa cishe zizoshesha kakhulu kunemishini yanamuhla.

Ngaphezu kwalokho, iningi lezinkampani zezimayini zisebenzisa izinqubo ze-chip yi-Taiwan Semiconductor Manufacturing Company (TSMC).I-Taiwan semiconductor foundry ihlela ukusheshisa izinqubo njenge-Intel futhi kungenzeka ukuthi i-TSMC ingahle ibe ngaphambi komdlalo kulokho.Naphezu kokuthi iyiphi inkampani ye-semiconductor eyakha ama-chips angcono ngokushesha, ukuthuthuka kwemboni yama-chip iyonke kuzoqinisa izinsimbi zezimayini ze-bitcoin ezakhiwa eminyakeni engamashumi amabili ezayo.
