Raws li kev hem thawj ntawm quantum tawm tsam ntawm crypto los ze zog rau materialising, kev lag luam npaj tau li cas rau qhov kev tshwm sim? Puas yuav crypto tuaj yeem tiv taus qhov kev tawm tsam no?
Asymmetric cryptography yog ua raws li txoj cai lej hu ua "ib txoj haujlwm". Qhov no ua rau tus yuam sij pej xeem tau muab los ntawm tus yuam sij ntiag tug, tab sis tsis yog lwm txoj hauv kev. Cov algorithms uas paub tam sim no yuav xav tau ntau lub sijhawm astronomically los rhuav tshem tus yuam sij uas nws tsuas yog tsis tuaj yeem ua tau.
Txawm li cas los xij, raws li a Deloitte tsab xov xwm, nyob rau hauv 1994, ib tug lej hu ua Peter Shor tau tsim ib tug algorithm uas yuav ua txhaum kev ruaj ntseg ntawm feem ntau asymmetric cryptography algorithms.
Qhov no txhais tau hais tias yog tias lub khoos phis tawj loj txaus tuaj yeem tsim tau, ces Shor's algorithm tuaj yeem siv los muab tus yuam sij ntiag tug los ntawm nws cov yuam sij rau pej xeem, tso cai rau tus neeg siv lub computer quantum ua cuav kos npe digital thiab nyiag tag nrho cov cryptocurrency hauv hnab nyiaj.
Dr Leemon Baird, co-founder ntawm Hedera, lub thib peb tiam pej xeem ledger rau siv los ntawm cov tuam txhab, tau hais nyob rau hauv ib tug tsab xov xwm los ntawm SiliconRepublic hais tias yog tias kev lag luam crypto tsis tau npaj, "kev npau suav phem" tuaj yeem tshwm sim. Nws hais tias:
"Qhov nws txhais tau li cas yog tias koj tuaj yeem rhuav tshem lub npe kos npe uas tso cai rau koj hais tias txawm tias cov tokens raug rho tawm ntawm koj tus as khauj. Ib tug neeg tuaj yeem nyiag txhua yam koj muaj, tag nrho koj cov cryptocurrency, tag nrho koj cov tokens, lawv tuaj yeem ua txhua yam hauv koj lub npe vim tias koj lub npe tsuas yog kos npe thiab lawv tuaj yeem sau koj daim ntawv kos npe. "
Nws ntxiv:
"Thiab koj tuaj yeem ua qhov txawv txawv xws li ob npaug ntxiv, qhov twg koj rhuav tshem blockchain nws tus kheej vim tias koj tau ua txhaum txoj haujlwm hash."
Baird tau hais tias txawm tias kev lag luam muaj kev ceeb toom ntau, thiab nws muaj peev xwm tiv thaiv "qhov chaw ntawm blockchain" tab sis ntawm tus nqi. Baird tau hais tias ib txoj hauv kev hu ua "hashing". Los ntawm kev tsim "me ntsis loj dua" nws ua rau nws nyuaj heev los twv qhov ntev ntawm cov tswv yim, yog li muab kev tiv thaiv los ntawm quantum computers.
Raws li Baird, qhov loj dua qhov tseem ceeb yuav tiv thaiv kev kos npe digital, tab sis qhov nyiaj uas lawv yuav tsum tau nce ntxiv yuav ua rau lawv "mob heev", ua rau blockchain qeeb thiab nce nqi.
Baird tau hais tias kev lag luam ib txwm muaj nrog kos npe digital ntawm 64 bytes, thaj tsam ntawm 100 txog 200 bytes. Txawm li cas los xij, los ntawm kev siv Falcon algorithm, qhov tsawg tshaj plaws ntawm 4 algorithms xaiv los ntawm US National Institute of Standards and Technology, kev hloov pauv yuav nce mus rau 1,300 bytes.
"Nws txhais tau tias koj yuav tsum xa ntau bytes, koj yuav tsum khaws ntau bytes, koj yuav tsum ua ntau bytes," Baird hais. "Txhua yam yog mob."
Txawm li cas los xij, nws tau hais tias qhov no yuav kho qhov teeb meem thiab hais tias qhov loj me me yuav dhau los tswj tau ntau dua.
"Tsis muaj leej twg yuav tuag vim peb tau muab 800 bytes lossis 1300 bytes kos npe, peb tuaj yeem muaj sia nyob nws," Baird hais. "Peb yuav ua nws ob xyoos txij li tam sim no thaum muaj tus qauv tiag tiag. Tsis muaj kev maj nrawm, tab sis peb yuav ua.
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.
