Oyendetsa migodi apamwamba a bitcoin ndi ma semiconductors a m'badwo wotsatira amayendera limodzi ndipo pamene teknoloji ya node ikukula, SHA256 hashrate imatsatira.Lipoti laposachedwa la Coinshares laposachedwa pazaka ziwiri zamigodi likuwonetsa kuti zida zamigodi zomwe zangoyambitsidwa kumene "zili ndi "ma hashrate 5x pagawo lililonse monga momwe adayambira kale."Ukadaulo waukadaulo waukadaulo wakula mosalekeza ndipo walimbikitsidwa kwambiri kupanga zida za ASIC.Komanso, nkhani zochokera ku International Electron Devices Meeting (IEDM) yomwe idachitika pa Disembala 7-11 ikuwonetsa kuti makampani opanga ma semiconductor akudutsa njira za 7nm, 5nm, ndi 3nm ndipo akuyembekeza kupanga tchipisi 2nm, ndi 1.4 nm pofika 2029.

2019's Bitcoin Mining Rigs Imapanga Hashrate Yambiri Kuposa Mitundu Yachaka Chatha

Pankhani ya migodi ya bitcoin, makampani opanga zida za ASIC akukula mwachangu.Zipangizo zamakono zimatulutsa ma hashrate kwambiri kuposa zida za migodi zomwe zidapangidwa zaka zapitazo ndipo zingapo zimatulutsa ma hashpower ochulukirapo kuposa zida za chaka chatha.Kafukufuku wa Coinshares adasindikiza lipoti sabata ino lomwe likuwonetsa momwe zida zamasiku ano zilili ndi "5x hashrate pa unit" poyerekeza ndi zida zam'badwo wakale.News.Bitcoin.com idaphimba kukwera kwa ma hashrate pagawo lililonse kuchokera pazida zomwe zidagulitsidwa mu 2018 ndipo kuwonjezeka kwa hashrate mu 2019 kwakhala kokulirapo.Mwachitsanzo, mu 2017-2018 zida zambiri zamigodi zidasintha kuchoka pa 16nm semiconductor standard kupita kumunsi kwa 12nm, 10nm ndi 7nm process.Pa December 27, 2018, makina apamwamba a migodi a bitcoin anatulutsa pafupifupi 44 terahash pamphindi (TH / s).Makina apamwamba a 2018 anali Ebang Ebit E11+ (44TH/s), Innosilicon's Terminator 2 (25TH/s), Bitmain's Antminer S15 (28TH/s) ndi Microbt Whatsminer M10 (33TH/s).

Mu Disembala 2019, zida zingapo zamigodi tsopano zikupanga 50TH/s mpaka 73TH/s.Pali zida zopangira migodi zamphamvu kwambiri monga Bitmain's Antminer S17+ (73TH/s), ndi mitundu ya S17 50TH/s-53TH/s.Innosilicon ili ndi Terminator 3, yomwe imati imapanga 52TH / s ndi 2800W yamphamvu pakhoma.Kenako pali zida ngati Strongu STU-U8 Pro (60TH/s), Microbt Whatsminer M20S (68TH/s) ndi Bitmain's Antminer T17+ (64TH/s).Pamitengo yamasiku ano komanso mtengo wamagetsi wa pafupifupi $0.12 pa kilowati-ola (kWh), zida zonse zamigodi zoyendetsedwa kwambiri zikupindula ngati migodi ya SHA256 network BTC kapena BCH.Kumapeto kwa lipoti la migodi ya Coinshares Research, phunziroli likukambirana ambiri a migodi ya m'badwo wotsatira omwe alipo, pamodzi ndi makina akale omwe akugulitsidwa pamisika yachiwiri kapena akugwiritsidwabe ntchito lero.Lipotilo limakhudza momwe makina amagwirira ntchito komanso mitengo kuchokera kwa opanga monga Bitfury, Bitmain, Kanani ndi Ebang.Chida chilichonse cha migodi chimapatsidwa "Kulingalira Kwambiri Mphamvu kuchokera ku 0 - 10," lipotilo likunena.

Pomwe Bitcoin Miners Amagwiritsa Ntchito 7nm mpaka 12nm Chips, Opanga Semiconductor Ali ndi Mapu a Njira za 2nm ndi 1.4nm

Kuphatikiza pa kuwonjezereka kwa magwiridwe antchito ndi zida zamigodi za 2019 poyerekeza ndi zitsanzo zomwe zidapangidwa chaka chatha, chochitika chaposachedwa cha IEDM chamakampani a semiconductor chikuwonetsa kuti ASIC migodi apitilizabe kusintha momwe zaka zikupitilira.Msonkhano wamasiku asanu udatsindika kukula kwa njira za 7nm, 5nm, ndi 3nm mkati mwa mafakitale, koma zatsopano zambiri zili m'njira.Ma Slides ochokera ku Intel, m'modzi mwa opanga opanga ma semiconductor padziko lonse lapansi, akuwonetsa kuti kampaniyo ikukonzekera kufulumizitsa njira zake za 10nm ndi 7nm ndipo ikuyembekeza kukhala ndi node ya 1.4nm pofika 2029. Sabata ino idatchulidwa koyamba za zomangamanga za 1.4nm mu Intel. slide ndi anandtech.com akuti mfundoyo "ingakhale yofanana ndi maatomu 12 a silicon kudutsa."Chiwonetsero chazithunzi cha IEDM kuchokera ku Intel chikuwonetsanso 5nm node ya 2023 ndi 2nm node mkati mwa nthawi ya 2029.

Pakali pano zida zamigodi za ASIC zopangidwa ndi opanga monga Bitmain, Kanani, Ebang, ndi Microbt makamaka amathandizira tchipisi ta 12nm, 10nm, ndi 7nm.Magawo a 2019 omwe amagwiritsa ntchito tchipisi izi akupanga kupitilira 50TH/s mpaka 73TH/s pagawo lililonse.Izi zikutanthauza kuti momwe njira za 5nm ndi 3nm zikulirakulira zaka ziwiri zikubwerazi, zida zamigodi ziyeneranso kusintha kwambiri.Ndizovuta kulingalira momwe zida za migodi zodzaza ndi 2nm ndi 1.4 nm tchipisi zidzachitira, koma zitha kukhala zothamanga kwambiri kuposa makina amasiku ano.

Kuphatikiza apo, makampani ambiri amigodi akugwiritsa ntchito njira za chip ndi Taiwan Semiconductor Manufacturing Company (TSMC).The Taiwan semiconductor foundry akukonzekera kufulumizitsa njira monga Intel ndipo ndizotheka kuti TSMC ikhoza kukhala patsogolo pamasewera pankhaniyi.Ngakhale kuti kampani ya semiconductor imapanga tchipisi tabwinoko mwachangu, kutukuka kwamakampani a chip kudzalimbikitsa zida zamigodi za bitcoin zomwe zikumangidwa pazaka makumi awiri zikubwerazi.
