Tus kws tshawb fawb UK tau lees tias Bitcoin's Algorithm tuaj yeem tawg hauv ib xyoo caum

Cov tub ntxhais kawm tiav kev tshawb fawb hauv kev lag luam quantum suav tau qhia tias Bitcoin's SHA-256 algorithm tuaj yeem tawg tsis pub dhau ib xyoo caum los ntawm quantum computer uas yog kwv yees li ib lab lub sij hawm muaj zog dua li cov qauv tshiab.

Raws li Mark Webber, tus kws tshawb fawb los ntawm Ion Quantum Technology Group ntawm University of Sussex, UK, SHA-256 algorithm raws li xa mus rau Bitcoin tuaj yeem tawg los ntawm kev tawg mus rau hauv encryption los ntawm 10-feeb qhov rais, xav tau lub computer quantum nrog. 1.9 billion qubits lossis quantum khoom. Yog tias lub qhov rais tawg tau nthuav dav mus rau ib teev, qhov yuav tsum tau poob rau 317 lab qubits.

Ion Quantum Technology Group yog ib lub koom haum tshawb fawb txhawb nqa los ntawm University of Sussex. Lawv txoj kev tshawb fawb suav nrog quantum xam thiab microwave quantum sensors. Lub cryptographic algorithm ntawm Bitcoin yog tsim los ntawm Satoshi Nakamoto raws li kev tshawb fawb uas twb muaj lawm rau SHA-256 kev ruaj ntseg raws tu qauv thawj zaug luam tawm los ntawm US National Security Agency (NSA) thaum tig ntawm lub xyoo pua.

Bitcoin's encryption algorithm tau tsim los tiv thaiv kev tawm tsam los ntawm nws cov blockchain, xws li tias nws yuav xav tau kev sib koom ua ke los ntawm 51% ntawm cov miners los tswj lub network tus nqi hash thiab ua rau pom kev tsis sib haum xeeb ntawm cov ntaub ntawv faib tawm tsis muaj kev tiv thaiv. Hauv qhov xwm txheej zoo li no, kev tswj xyuas miner yuav tiv thaiv kev lees paub kev lag luam, ua kom lub network qeeb qeeb thiab thaiv kev hloov pauv thiab them nyiaj ntawm cov neeg siv chaw nyob.

Cov lej yuav zoo li xav tsis thoob thiab nyob deb, tab sis cov qauv tam sim no rau lub khoos phis tawj superconducting quantum tau tso tawm ob lub hlis dhau los: IBM's 127 qubit 'Eagle' Quantum Processor. Muab qhov kev paub dhau los no, qhov kwv yees los ntawm Webber thiab nws pab pawg tshawb fawb yuav xav tau lub khoos phis tawj quantum uas yog kwv yees li ib lab npaug sai dua li cov tiam tam sim no.

Quantum suav ua haujlwm los ntawm kev siv lub hauv paus quantum xwm ntawm cov teeb meem ntawm qib subatomic, fusing nws mechanics los muab amplified suav hwj chim rau processors tsim raws li nws specifications. Los ntawm kev siv quantum circuits teem los ntawm qubits rau hauv quantum rooj vag, quantum computers xws li IBM's Eagle Quantum Processor muaj peev xwm khiav thiab daws cov kev suav nyuaj.

"Tib neeg twb txhawj xeeb vim tias koj tuaj yeem khaws cov lus encrypted tam sim no thiab decrypt lawv yav tom ntej. Yog li muaj kev txhawj xeeb loj uas peb yuav tsum tau hloov pauv peb cov txheej txheem encryption, vim tias yav tom ntej, lawv tsis muaj kev nyab xeeb. " Webber qhia.

Webber yog, tau kawg, tham txog dab tsi tau hu ua "quantum supremacy" hauv cov zej zog kev tshawb fawb thiab thev naus laus zis. Quantum supremacy yog hais txog qhov pib ntawm qhov programmable quantum ntaus ntawv yuav daws tau qhov teeb meem uas tsis muaj lwm lub khoos phis tawj classical tuaj yeem daws tau txhua lub sijhawm.

Kev tshawb fawb tsis ntev los no hauv quantum xam los ntawm Hartmut Neven, tus thawj coj ntawm Quantum Artificial Intelligence lab, tau qhia tias quantum xam cov neeg kho tshuab ib txwm overrides Moore Txoj Cai, uas txiav txim siab tias tus nqi ntawm cov transistors hauv ib qho microchip muab ob npaug rau txhua ob xyoos, nrog rau cov nqi tsim tawm ib nrab ntawm tib lub sijhawm. Nrog "Neven's Law," hauv kev ua si, quantum suav lub zog tau hais tias yog "kev loj hlob ob npaug ntxiv rau kev suav nrog."

Muab cov duab no, Webber pom Bitcoin qhov kev ruaj ntseg algorithms tam sim no yuav siv tau tsuas yog rau lwm xyoo caum los yog li ntawd. Nws yog qhov yuav tshwm sim, thiab thaum nws tshwm sim, kev lag luam crypto raws li peb paub tias nws yuav tsum tau hloov thiab hloov mus rau qhov tshwm sim ntawm quantum xam tshuab thiab tiv thaiv Bitcoin cov keeb kwm.

Tsis kam lees: Cov lus no tsuas yog muab ua kev qhia xov xwm nkaus xwb. Nws tsis yog muab los yog npaj rau siv raws li kev cai lij choj, se, peev, nyiaj txiag, lossis lwm yam kev qhia.
