Hauv lub ntiaj teb ntawm "kev txaus siab", nws yog ib qho tseem ceeb uas tsis muaj leej twg muaj kev ywj pheej ntawm qhov tseeb.
Decentralized raws tu qauv tau loj hlob nyob rau hauv muaj koob meej raws li siv tau lwm txoj rau ib txwm centralized systems. Tib neeg tau lees paub qhov tsis zoo ntawm lub hauv paus tswj hwm thiab txais kev qhib, kev faib tawm, thiab tsis muaj kev ntseeg siab. Txawm li cas los xij, rau cov txheej txheem decentralized kom qhib tau tiag tiag thiab pob tshab, yuav tsum muaj kev tsim kho vaj tse uas yuav pab nkag mus rau cov ntaub ntawv offline ntawm lub sijhawm tiag tiag hauv qhov tsis ntseeg.
Tsis muaj qhov tsis ntseeg tias peb nyob hauv lub ntiaj teb uas leej twg tuaj yeem qhia cov ntaub ntawv cuav thiab tshaj tawm tias nws muaj tseeb. Oracles zoo li yog qhov kev daws teeb meem rau lub vev xaib uas muaj kev cuam tshuam los ntawm "infrastructure" teeb meem. Oracles yog qhov tseem ceeb blockchain infrastructure uas pab txhawb kev sib txuas lus ntawm offline thiab on-chain raws tu qauv.
Oracles yog qhov tseem ceeb rau feem ntau cov txheej txheem decentralized, tshwj xeeb tshaj yog Decentralized Finance. Decentralized Finance (DeFi) cov txheej txheem cia siab rau Oracle tes hauj lwm rau lub sijhawm tiag tiag ntawm cov ntaub ntawv xov xwm thiab cov txiaj ntsig tshwm sim vim tias blockchains tsis muaj ib txoj hauv kev nkag mus rau cov ntaub ntawv sab nraud ntawm cov chains lawv tus kheej, thiab cov ntawv thov kev ncaj ncees (dApps) xws li cov khoom pov hwm, algorithmic stabilitycoins, nyiaj txiag derivatives, thiab kev twv ua lag luam, yuav tsum ua haujlwm zoo.
Oracles sau cov ntaub ntawv hauv ntiaj teb no los ntawm lwm qhov chaw, xws li cov nqi lag luam, cov ntaub ntawv huab cua, cov ntaub ntawv qhov chaw, thiab cov nqi txiaj, thiab muab tso rau hauv blockchain, tso cai rau cov ntawv cog lus ntse ua rau nws. Lawv tuaj yeem muab cov ntaub ntawv los ntawm cov saw sib txawv.
Thaum tus txheej txheem tsis yog decentralized, oracles feem ntau yog cov kev pabcuam thib peb lossis daim ntawv thov nta uas tus neeg siv cuam tshuam nrog manually. Cov no tsis ua raws li cov kev xav ntawm decentralized raws tu qauv thiab yog, feem ntau, centralized. Centralized oracles tuaj yeem tswj tau yooj yim thiab siv rau lub hom phiaj qia dub. Lub hom phiaj ntawm blockchain oracles yog los muab ntau cov ntaub ntawv txhim khu kev qha kom ua tiav kev faib tawm.
Txhawm rau ua tiav qhov no, blockchain oracles sib txuas cryptography thiab kev txhawb siab los tsim cov tshuab uas tso cai rau cov nodes sib txawv kom ncav cuag qhov kev pom zoo ntawm cov ntaub ntawv sib koom. Txawm li cas los xij, qhov no yuav ua rau tsis muaj zog rau cov txheej txheem decentralized. Manipulation tuaj yeem tshwm sim thaum siv cov nqi noj khoom noj oracle, thiab tau muaj ntau qhov xwm txheej siab, ib qho yog thaum qiv ntawm DeFi platform Compound. liquidated rau US $ 103 lab vim lub siab phem oracle exploit. Qhov kev ua tsis tiav ntawm 3AC, Celsius, thiab BlockFi txhua tus hais txog qhov tseem ceeb ntawm kev ua kom muaj kev ncaj ncees tiag tiag raws li kev ua kom pom tseeb thiab kev ntseeg siab hauv cov nyiaj txiag.
Thaum lub lag luam dais tseem hnyav rau cryptos thiab DeFi ib yam nkaus, cov chav kawm tshiab yuav tsum tau teev yog tias DeFi yuav muaj sia nyob thiab vam meej. Txawm li cas los xij, oracles yuav yog ib qho ntawm cov tsav tsheb muaj zog tshaj plaws ntawm qhov kev hloov pauv no.
Band Protocol yog ib qho ntawm Decentralized Oracle raws tu qauv paving txoj kev rau yav tom ntej evolution ntawm Defi Ecosystem. Qhab Kev Sib Tw muab cov ntaub ntawv "cov zej zog-curated" uas cov neeg ua haujlwm dApp tuaj yeem siv los tswj thiab kho cov ntaub ntawv txau kom daws tau qhov teeb meem oracle thiab muab cov ntawv cog lus ntse nrog cov ntaub ntawv pov thawj. Band tau txais kev mloog ntau heev txij li thaum nws pib hauv 2018 thiab paub zoo tias yog ib qho ntawm qhov zoo tshaj plaws decentralized oracles hauv kev lag luam.
Lwm Oracle raws tu qauv tsim nyog hais txog yog QED raws tu qauv. LIAB yog lub tiam tom ntej decentralized oracle daws rau blockchain sector. 0rigin tsim tus qauv kev lag luam muaj zog hu ua QED los txuas ntau yam blockchains, cov ntawv cog lus ntse, thiab cov ntaub ntawv tawm ntawm cov saw hlau. Lub Delphi oracle tau nyob thiab ua haujlwm tau ntau tshaj peb xyoos. QED yog kev sib ntaus sib tua-kuaj thiab ua pov thawj iteration ntawm Delphi oracle.
Muab hais tias QED yog thawj qhov kev daws teeb meem ntawm Oracle los daws cov txheej txheem thiab kev lag luam ntawm Oracle raws tu qauv, nws muaj qhov sib txawv tus nqi. Tsis tas li ntawd, QED tau tsim cov qauv kev lag luam muaj zog uas ua rau nws sib nrug los ntawm lwm cov txheej txheem blockchain los ntawm kev lees paub qhov tseeb ntawm cov ntaub ntawv hauv ntiaj teb tiag ntawm cov saw hlau.
Vim tias QED raws tu qauv yog blockchain agnostic, nws tuaj yeem ntsuas thiab sib xyaw nrog txhua qhov qhib blockchain. Ntawm kev lag luam sab nrauv, QED tau muab tso rau hauv cov txheej txheem nyiaj txiag zoo uas tso cai rau cov neeg siv khoom siv nyiaj txiag sab nraud nws tau muab rau lawv nyob rau hauv rooj plaub qhov kev pheej hmoo yuav raug liam. Thaum kawg, nws yog ib qho tseem ceeb kom nco ntsoov tias QED network yeej tsis siv qhov system tokens raws li kev lav phib xaub thiab hloov ib txwm siv cov khoom siv sab nraud.
xaus
Centralization tau ua rau muaj kev ruaj ntseg ntau yam nyob rau hauv tam sim no Oracle raws tu qauv thiab DeFi ecosystem tag nrho. Hackers nyiag txog $ 1.3 nphom hauv xyoo 2021 vim qhov tsis zoo ntawd. Kuj tseem muaj cov piv txwv uas "centralized" Oracles ua rau muaj qhov tsis sib xws hauv cov nqi lag luam thiab cov ntaub ntawv thoob plaws platforms. Peb pom Venus raws tu qauv raug siv los ntawm cov neeg ua yeeb yam tsis zoo, raug nqi 11 lab daus las, raws li cov neeg nyiag nkas coj kom zoo dua ntawm Venus tus nqi hloov pauv. Decentralized oracle raws tu qauv, xws li QED tes hauj lwm, yog lub neej yav tom ntej ntawm DeFi kev lag luam thiab yuav pab tau cov tub ua lag luam nyob rau hauv lub tam sim no theem ntawm kev lag luam volatility thiab dais lag luam nyob rau hauv lub cryptocurrency chaw.
