Okwamanje, ama-blockchains ahlukaniswe kakhulu emithonjeni yangaphandle yolwazi - zombili izinsiza ezimaphakathi kanye namanye ama-blockchain. Ukuqinisekisa ukuthi ama-blockchain ahlukene ayahambisana futhi ashintshanisa kalula idatha phakathi kwabo (kanye nezinsiza zangaphandle), ama-oracle angasetshenziswa.
Ayini ama-oracle
I-oracle iyisistimu eyamukela futhi iqinisekise imicimbi ngaphandle kwe-blockchain futhi idlulisele le datha ku-blockchain ukuze isetshenziswe kuzinkontileka ezihlakaniphile (noma okuphambene nalokho). Ama-oracle abalulekile ezinkontilekeni ezihlakaniphile ngoba izinkontileka ezihlakaniphile zinquma kakhulu. Ulwazi kufanele lungene kwinkontileka ehlakaniphile ngesiteshi esithile esingaqinisekisa ukunemba kwayo.
Kunezinhlobo ezimbalwa zezibikezelo ezinikeza uhlobo olulodwa noma olunye lokuxhumana:
- isofthiwe - thola idatha ku-Inthanethi noma kwamanye ama-blockchains;
- i-hardware - thola idatha kusuka kuzinzwa ezahlukahlukene ( amathegi, ikhaya elihlakaniphile; mathupha, izinhlelo zokusebenza ku-logistics kanye ne-IoT zifika ngokushesha engqondweni);
Isibonelo: idatha yezinga lokushisa lomoya idinga ukudluliselwa kunkontileka ehlakaniphile. Ungathatha idatha ku-inthanethi usebenzisa i-software oracle, noma inzwa ye-IoT ngokusebenzisa i-hardware oracle. *IoT
- engenayo - kusuka ngaphandle kwe-blockchain ungene kwinkontileka ehlakaniphile;
- eziphumayo - kusukela kwinkontileka ehlakaniphile ukuya kumthombo othile;
Ngezinye izikhathi kusetshenziswa izinkulumo zokuvumelana. Ama-oracle amaningana athola idatha ngokuzimela, bese esebenzisa i-algorithm ethile ukuze anqume okukhiphayo.
Isibonelo sokuthi kungani lokhu kudingekile: ama-oracle angu-3 athola izinga le-BTC/USD kusuka ku-Binance, BitMex naku-Coinbase, futhi adlulisele inani elimaphakathi njengokuphumayo. Lokhu kulungisa ukungezwani okuncane phakathi kokuhwebelana.
I-Web3
Uma ukhuluma ngama-oracle kanye nokusetshenziswa kwawo, umuntu akakwazi ukuziba i-Web3, umqondo ezasungulelwa wona. I-Web3 ekuqaleni ibiwumbono wewebhu ye-semantic, lapho yonke isayithi imakwe ngemethadatha ukuthuthukisa ukusebenzisana nezinjini zokusesha. Kodwa-ke, umbono wesimanje weWeb3 yinethiwekhi equkethe i-dApps. Futhi izinhlelo zokusebenza ezinwetshiwe zidinga izisho.
Kungenzeka (futhi, kwezinye izimo, kudingekile) ukuze uzenzele i-oracle, kodwa kukhona ama-oracle avame ukusetshenziswa (isibonelo, i-generator yenombolo engahleliwe), ngakho kubiza kakhulu ukusebenzisa amaphrojekthi we-oracle. Amaphrojekthi amabili amakhulu (okwamanje) athuthukisa izibikezelo yilezi: ΠΈ .
I-Band Protocol
I-Band Protocol isebenza nge-algorithm yokuvumelana ye-dPoS () futhi abahlinzeki bedatha banesibopho sobuqiniso ngemali, hhayi nje isithunzi.
Kunezinhlobo ezintathu zabasebenzisi ku-ecosystem yephrojekthi:
- Abahlinzeki bedatha abasebenza ngokuzimela ukudlulisa idatha ngokuphephile isuka ngaphandle kwe-blockchain iye ku-blockchain. Abanikazi bamathokheni babheja abahlinzeki bedatha ukuze babanikeze ilungelo lokuhambisa idatha kuphrothokholi.
- Onjiniyela be-DApp abakhokha imali encane ukusebenzisa i-oracle.
- Abanikazi bamathokheni ebhendi abavotela abahlinzeki bedatha. Ngokuvota ngamathokheni abo kumhlinzeki, bathola umklomelo emalini ekhokhwe ama-dApps.
Phakathi kwezimemezelo ezinikezwa i-Band ephuma ebhokisini: izikhathi zokusuka kwendiza/izikhathi zokufika, imephu yesimo sezulu, amanani e-cryptocurrency, amanani egolide namasheya, ulwazi mayelana namabhulokhi we-Bitcoin, intengo yegesi emaphakathi, amavolumu ekuhwebeni kwe-crypto, i-generator inombolo engahleliwe, i-Yahoo Finance, i-HTTP Ikhodi Yesimo.
Ngendlela, phakathi kwabatshalizimali be-Band kunesikhwama esidumile sokuhweba ΠΈ .
I-Chainlink
Ngokuvamile, i-Chainlink ne-Band zifana kakhulu - kokubili kuzixazululo ezizenzakalelayo nasemandleni okuthuthukisa. I-Chainlink kulula ukuyisebenzisa, akukho ukuvotela abahlinzeki bolwazi, futhi i-Band ivumelana nezimo ngoba isebenzisa futhi ingumthombo ovulekile ongu-100%.
Njengamanje, i-Chainlink idume kakhulu, i-Google Cloud, i-Binance, i-Matic Network ne-Polkadot ohlwini lozakwethu bephrojekthi. I-Chainlink iphinde yagxila kuma-oracles wendawo , manje ekhula ngokushesha.
Izinsiza idatha yazo engatholwa nge-oracle evela ku-Chainlink.
isiphetho
Ama-Oracles awumqondo omuhle wokuthola idatha kusuka kuzinsiza ezimaphakathi ku-blockchain, futhi ngizobe ngibhekisisa ukuthuthuka kwayo eduze. Kodwa-ke, uma sikhuluma ngokuhambisana kwama-blockchain ahlukene, kunezinye izixazululo, kufaka phakathi ama-parachains (ubuchwepheshe obuthembisa nakakhulu kanye nesihloko sokuthunyelwe kwami ββββokulandelayo).
