Qhov chaw tshawb fawb ntawm Bitcoin (BTC)-tseem ceeb blockchain tech tuam txhab Blockstream tau tshaj tawm cov lus pom zoo rau ib hom tshiab ntawm ntau tus qauv hu ua Robust Asynchronous Schnorr Threshold Signatures (ROAST).
Nws cia siab tias yuav zam tsis tau qhov teeb meem ntawm kev lag luam tsis ua haujlwm vim tsis tuaj lossis txawm tias cov neeg kos npe tsis zoo thiab tuaj yeem ua haujlwm ntawm qhov ntsuas.
Lo lus multisig, los yog multisignature, yog hais txog ib txoj kev ntawm kev lag luam uas ob los yog yuav tsum tau kos npe ntau ntxiv ua ntej nws yuav raug tua. Tus qauv yog dav saws nyob rau hauv crypto.
raws li rau hnub Wednesday blog tshaj tawm los ntawm kev tshawb fawb Blockstream, lub tswv yim tseem ceeb ntawm ROAST yog ua kev lag luam ntawm Bitcoin network thiab Blockstream's sidechain Liquid ntau npaum, automated, ruaj ntseg thiab private.
Tshwj xeeb, ROAST tau raug tso tawm raws li tus qauv kos npe uas tuaj yeem ua haujlwm nrog, thiab txhim kho, pib kos npe schemes xws li Flexible Round-Optimized Schnorr Threshold Signatures FROST):
"ROAST yog ib qho yooj yim wrapper nyob ib ncig ntawm qhov pib kos npe schemes zoo li FROST. Nws tau lees paub tias pawg neeg kos npe ncaj ncees, piv txwv li, Liquid functionaries, tuaj yeem tau txais daim ntawv kos npe siv tau txawm tias muaj kev cuam tshuam rau cov neeg kos npe thaum kev sib txuas hauv network muaj arbitrarily siab latency. "
Cov kws tshawb fawb tau hais tias thaum FROST tuaj yeem yog txoj hauv kev zoo rau kos npe tawm ntawm BTC kev lag luam, nws cov qauv ntawm cov neeg koom tes thiab cov neeg kos npe yog tsim los rho tawm kev lag luam nyob rau hauv lub xub ntiag ntawm cov neeg kos npe tsis tuaj, ua rau nws ruaj ntseg tab sis tsis zoo rau "automated kos npe software."
Txhawm rau daws qhov teeb meem no, cov kws tshawb fawb hais tias ROAST tuaj yeem lav cov neeg kos npe txaus ntseeg ntawm txhua qhov kev sib pauv kom tsis txhob muaj qhov ua tsis tiav. Ntxiv mus, nws tuaj yeem ua tiav ntawm qhov ntsuas loj dua li 11-ntawm-15 multisig tus qauv uas Blockstream feem ntau siv.
"Peb qhov kev ntsuam xyuas kev ua tau zoo qhia tau hais tias ROAST ntsuas tau zoo rau pawg neeg kos npe loj, piv txwv li, 67-ntawm-100 teeb tsa nrog tus neeg koom tes thiab cov neeg kos npe ntawm ntau lub teb chaws," tus tshaj tawm nyeem, ntxiv tias:
"Txawm tias muaj 33 tus neeg kos npe tsis zoo uas sim thaiv kev sim kos npe (xws li xa cov lus teb tsis raug lossis tsis teb txhua), 67 tus neeg kos npe ncaj ncees tuaj yeem ua tiav kos npe hauv ob peb feeb."
Txhawm rau muab cov lus piav qhia yooj yim ntawm ROAST ua haujlwm li cas, pab pawg tau siv qhov piv txwv ntawm pawg tswj hwm kev ywj pheej lub luag haujlwm rau txoj cai lij choj ntawm Frostland.
Qhov tseem ceeb, qhov kev sib cav tau muab hais tias nws tuaj yeem nyuaj kom tau txais kev cai lij choj (kev lag luam) kos npe tawm hauv Frostland, vim tias muaj ntau ntau yam ntawm txhua lub sijhawm uas tuaj yeem ua rau feem coob ntawm cov tswv cuab tam sim no tsis muaj lossis tsis tuaj.
Ib txoj haujlwm (ROAST) los tawm tsam qhov no, yog rau tus tuav ntaub ntawv hauv pawg sab laj los sau thiab khaws cov npe loj txaus ntawm cov tswv cuab hauv pawg sab laj (cov neeg kos npe) nyob rau lub sijhawm twg los tau kom muaj cov tswv cuab txaus kom tau txoj cai los ntawm:
"Yog tias tsawg kawg yog xya tus tswvcuab hauv pawg thawjcoj yeej txhawb nqa tsab cai lij choj thiab coj ncaj ncees, tomqab ntawd lub sijhawm twg los xij, nws paub tias xya tus tswvcuab yuav tsum kos npe rau lawv daim ntawv tam sim no thiab muab ntxiv rau tus tuav ntaub ntawv cov npe."
"Yog li tus tuav ntaub ntawv yeej ib txwm paub tseeb tias xya tus tswvcuab yuav nyob hauv nws daim ntawv teev npe dua nyob rau qee lub sijhawm yav tom ntej, thiab yog li cov txheej txheem kos npe yuav tsis poob," tus tshaj tawm ntxiv.

ROAST yog ib feem ntawm kev koom tes ntawm Blockstream cov kws tshawb fawb Tim Ruffing thiab Elliott Jin, Viktoria Ronge thiab Dominique Schröder los ntawm University of Erlangen-Nuremberg thiab Jonas Schneider-Bensch los ntawm CISPA Helmholtz Center for Information Security.
Nrog rau cov ntawv tshaj tawm blog, cov kws tshawb fawb tseem txuas nrog 13-nplooj ntawv tshawb fawb uas muab ib qho rundown ntawm ROAST hauv ntau dua.
