Crypto FUD yog Ntshai Uncertainty thiab Doubt propagated mus tua cryptos thiab feem ntau yog unverified / cuav tseeb txog lub tshuab. FUDs muaj ntau yam hauv kev lag luam sib txawv deb ntawm cryptocurrencies tsuav yog kev lag luam koom nrog. Qhov kev lag luam tsis zoo no tau ua rau cov neeg tsis txhob sim cov khoom tshiab lossis cov khoom nrov rau ntau xyoo. Ib qho ntawm qhov tseem ceeb crypto FUDs yog tias Quantum suav yuav dwarf qhov kev ruaj ntseg hauv crypto technology.
Claim
Muaj kev thov tias kev ruaj ntseg cryptocurrency yuav raug kev txom nyem nyob rau hauv lub era ntawm quantum xam. Txoj kev xav piav qhia tias cov khoos phis tawj no yuav muaj zog heev uas lawv yuav rhuav tshem cov algorithms tom qab ntau qhov loj crypto blockchains. Nws tau nthuav tawm los ntawm cov neeg sib txawv, suav nrog cov kws tshawb fawb los ntawm University of Sussex, qhia lawv qhov kev ntshai tias BTC yuav yog cov nyiaj npib uas yuav poob rau hauv tes ntawm quantum xam.
Webber thiab nws pab neeg tau tshaj tawm ib tsab xov xwm hauv thawj lub lim tiam ntawm Lub Ob Hlis 2022 piav qhia tias quantum suav yuav ua rau muaj kev phom sij rau cryptocurrencies. Daim ntawv tshaj tawm tau piav qhia tias lub ntiaj teb ceev tshaj plaws thiab ua tau zoo supercomputer, IBM Supercomputer, tuaj yeem rhuav tshem Bitcoin's SHA-256 algorithm.
Txawm li cas los xij, nws hais ntxiv tias lub sijhawm txwv uas lub khoos phis tawj yuav siv los ua kom tiav cov txheej txheem ntawm kev rhuav tshem cov algorithm tsis tau txhais meej meej. Lwm cov kws tshawb fawb tau qhia txog kev txhawj xeeb txog SHA-256 pawg algorithms ua rau muaj kev cuam tshuam rau quantum xam. Cov algorithms no feem ntau yog siv los encrypt cov yuam sij siv los tiv thaiv cryptos.

Tshawb xyuas qhov tseeb
Raws li kev tshawb fawb ua los ntawm pab pawg ntawm Sussex, lawv tau xaus lus tias tsuas yog lub tshuab computer uas muaj lub zog ua haujlwm ntau dua 317 Quantum Bits tuaj yeem rhuav tshem SHA-256 algorithm hauv ib teev lossis ob. Lub sijhawm tam sim no, IBM supercomputer boasts nyob ib ncig ntawm 127 qubits qhia tias nws tseem nyob deb ntawm qhov 'muaj peev xwm' ua lub zog yuav tsum tau pib ua rau kev puas tsuaj rau Bitcoin algorithms.
Rau Bitcoin lub blockchain kom tawg, lub supercomputer yuav tsum tau ua ib tug 50 + 1 nres uas koom nrog cov blocks 'mining txheej txheem. Bitcoin mining yog ua tiav siv cov cuab yeej tshwj xeeb hu ua Application Specific Integrated Circuits (ASICs), tshwj xeeb tsim rau cov mining rigs. Cov circuits siv txoj kev programming / hash muaj nuj nqi hu ua "puzzle friendliness," qhov twg txhua qhov kev tawm tswv yim yuav tsum muab cov txiaj ntsig zoo, thiab yog tias tsis yog, nws raug kuaj pom los ntawm tag nrho cov kab ke, thiab cov miner tau txais kev ceeb toom.
Qhov ntawd txhais tau tias kev ua haujlwm ntawm ASICs tsis tuaj yeem pib cuam tshuam los ntawm ib lub khoos phis tawj yam tsis muaj txhua tus miners ua haujlwm ntawm tib lub thaiv tau ceeb toom ib txhij. Revisiting lub super computer lub zog ua piv rau Bitcoin qhov ceev, Bitcoin boasts ib tug hashrate ntau tshaj. 80,704,000 PetaFLOPS, thaum IBM lub supercomputer sawv ntawm me ntsis dhau 442 PetaFLOPS nyob rau hauv Lub Xya hli ntuj 2021.
Tsis tas li ntawd, xav txog kev thaiv kev tsim tawm ntawm Bitcoin, qhov hashrate nce ntxiv vim qhov nyuaj ntawm kev tsuas yog nce vim qhov nyiaj npib mus txog qhov kawg ntawm 2 lab npib. Cov npib yuav raug mined mus txog 2140, qhia tias supercomputers tseem yuav tsis tau tsim txaus los ua rau muaj kev hem thawj rau BTC tom qab ntawd.
Qhov Tseeb Txog Kev Thov
Bitcoin muaj qhov nrawm dua li txhua lub khoos phis tawj muaj los ua qhov kev thov, thiab qhov tseeb yooj yim rau leej twg nkag siab. Yog li ntawd, nws tseem muaj kev nyab xeeb los ntawm kev cuam tshuam los ntawm ib qho ntawm lawv. Nws tseem tab tom mus txog nws hnub kawg ntawm kev mining npib. Qhov ntawd txhais tau hais tias nws qhov nyuaj mining yuav nce siab, tshaj qhov kev txhim kho hauv supercomputers.
Yog li ntawd, nws tau lees tias lub npib yuav nyob nyab xeeb ntawm quantum computers txog 2140 thaum lub npib kawg yuav raug mined. Tsis tas li ntawd, tsis muaj kev qhia dab tsi lub npib lub hashrate yuav yog vim nws nce exponentially raws li cov nyiaj npib txo. Qhov ntawd txhais tau tias nws tseem yuav muaj kev nyab xeeb los ntawm quantum computers rau ntau tshaj li ib puas xyoo tom qab 2140.
Xav tias qhov chaw crypto tau sau nrog qee lub siab zoo tshaj plaws hauv ntiaj teb, nws yog qhov tseeb tias lawv yuav los nrog cov kev daws teeb meem los tiv thaiv blockchain thev naus laus zis xyoo ua ntej quantum suav ua rau muaj kev hem thawj tiag tiag. Yog li ntawd, qhov kev thov tias cryptos tsis muaj kev nyab xeeb nyob rau hauv txhais tes ntawm quantum xam yog FUD uas yuav tsum tsis txhob saib xyuas!
