Kev tshuaj xyuas MIT thev naus laus zis tsis ntev los no tau nrhiav kev txo qis qhov tseem ceeb ntawm lub sijhawm ze ntawm quantum xam rau Bitcoin (BTC) thiab lwm yam cryptocurrencies. Hauv ib daim ntawv luam tawm thaum Lub Peb Hlis 28, 2022, tus kws tshaj lij Asmeskas theoretical physicist Sankar Das Sarma, tau hais tias muaj ntau dhau hype nyob ib puag ncig qhov tsis txaus ntseeg ntawm quantum suav.
Quantum Computer thiab Bitcoin
Hauv ob peb xyoos dhau los, cov kws tshawb fawb thiab cov kws tshuaj ntsuam xyuas kev lag luam ib yam nkaus tau tshaj tawm qhov ua tau zoo ntawm quantum suav ntawm blockchain thev naus laus zis feem ntau, thiab cryptocurrencies tshwj xeeb. Feem ntau, qhov kev txiav txim tau nyob ze-unanimous: quantum xam yuav muaj lub peev xwm los yooj yim tawg cov yuam sij cryptographic ruaj cryptos xws li Bitcoin.
Cov cryptographic primitives uas ruaj ntseg Bitcoin yog tsim los ntawm supposedly unsolvable lej teeb meem. Tab sis nws cia siab tias quantum computers yuav muaj lub zog suav los daws cov teeb meem no thiab yog li ua rau tsis muaj txiaj ntsig kev pom zoo algorithms xws li pov thawj-ntawm-ua haujlwm lossis pov thawj ntawm ceg txheem ntseeg.
Tsis tas li ntawd, cov kws tshaj lij kuj tau hais tias cov neeg ua yeeb yam tsis zoo tuaj yeem siv quantum computers rau kuv Bitcoin ntau dua li cov khoos phis tawj classical tam sim no muaj peev xwm.
Hypothetically, yog tias ib pab pawg miners yuav tsum tswj tsawg kawg yog 50% ntawm Bitcoin network kev suav lub zog siv quantum computers, lawv tuaj yeem siv cov kev tswj feem ntau rau txhua yam kev ua phem ntawm lawv xaiv.
Quantum Computing tseem tsis tau Advanced txaus los tsim kev hem thawj rau Bitcoin
Txawm li cas los xij, Sankar qhia tias, raws li nws tam sim no, lub tswv yim ntawm quantum xam yog ntau hype tshaj cov khoom. Raws li University of Maryland xibfwb, tseem muaj txoj hauv kev ntev mus ua ntej quantum thev naus laus zis cov kws tshawb fawb tuaj yeem tsim lub tsev muaj zog txaus los rhuav tshem cov cryptography ruaj ntseg cov cuab tam xws li Bitcoin.
Pom tau tias, qhov teeb meem tseem ceeb cuam tshuam kev nce qib hauv quantum xam yog qhov teeb meem me me ntawm quantum yuam kev kho.
Kev kho qhov yuam kev Quantum yog cov txheej txheem uas quantum computers tuaj yeem them nyiaj rau decoherence, thiab nws tau ua pov thawj tias yog cov txiv ntoo tawv kom tawg.
Hauv nws daim Technology Review, Sarma tau hais tias:
"Lub tshuab quantum siab tshaj plaws niaj hnub no muaj ntau ntau lub cev qubits decohering. Tsim kom muaj lub computer quantum uas tuaj yeem tawg RSA cov lej tawm ntawm cov khoom zoo li no yuav xav tau ntau lab yog tias tsis yog billions ntawm qubits. Tsuas yog kaum tawm txhiab tus ntawm cov no yuav raug siv rau kev xam-hu ua logical qubits; tus so yuav xav tau rau kev kho qhov yuam kev, them nyiaj rau decoherence. "
Thaum cov qubit systems siv niaj hnub no yog ib qho tseem ceeb ntawm kev siv technology, Sarma ntseeg tias lawv tseem tsis tau coj cov quantum suav nrog ib qho ze rau kev ua tiav.
Bitcoin Mining nyuaj ncav cuag txhua lub sijhawm siab
Lwm qhov, Bitcoin qhov nyuaj tsuas yog dhia mus rau txhua lub sijhawm siab ntawm 28.587 trillion. Qhov nce hauv qhov nyuaj tuaj sai sai tom qab cov miners tso tawm 19 lab BTC chav nyob rau hauv kev ncig.
Nrog rau qhov siab tshaj plaws ntawm 21 lab BTC, tam sim no tsuas muaj 2 lab npib uas yuav tsum tau khawb. Qhov no txhais tau hais tias qhov seem BTC blocks yuav nce mus rau qhov xav tau ntau dua kev suav lub zog rau kuv vim lawv tsis tshua muaj.
Lub caij no, Bitcoin tus nqi txuas ntxiv thawb saum $ 45k raws li nws caij nthwv dej ntawm kev txhim kho kev lag luam.
Thaum lub sijhawm sau ntawv, Bitcoin raug nqi ntawm $ 46,599. Qhov no yog 3.24% nce los ntawm qib dhau los ntawm 24 teev dhau los. Nyob rau tib lub sijhawm, BTC tau sau npe ua lag luam ntim ntawm $ 34,127,586,241, thiab muaj lub khw muag khoom ze li $ 886 billion, ua rau nws yog qhov loj tshaj thiab muaj txiaj ntsig zoo tshaj plaws cryptocurrency los ntawm deb.
Cov neeg soj ntsuam yuav txuas ntxiv saib xyuas cov xwm txheej tsim kho hauv Ukraine kom pom tias nws yuav cuam tshuam li cas rau kev lag luam crypto, tab sis cov xov xwm ntawm Bitcoin qhov kev ruaj ntseg ruaj ntseg, tsawg kawg nyob rau lub sijhawm ze, yuav tsum txhawb cov tub ua lag luam kev ntshai los ntawm kev tshaj tawm kev xav ntawm lub imminent nyhuv ntawm quantum xam ntawm crypto.
