Oracle ke sistimi e amohelang le ho netefatsa liketsahalo tse tsoang kantle ho blockchain mme e fetisetsa data ena ho blockchain hore e sebelisoe likonteraka tse bohlale (kapa ka tsela e fapaneng). Li-Oracles li bohlokoa ho likonteraka tse bohlale hobane likonteraka tse bohlale li ikemiselitse haholo. Tlhahisoleseding e tlameha ho kenya konteraka e bohlale ka mocha o itseng o ka netefatsang ho nepahala ha eona.
Ho na le mefuta e 'maloa ea linohe tse fanang ka mofuta o le mong kapa o mong oa puisano:
- software - fumana data ho tsoa inthaneteng kapa ho tsoa ho li-blockchains tse ling;
- hardware - fumana data ho tsoa ho li-sensor tse fapaneng ( li-tag, ntlo e bohlale; ka bonna, lits'ebetso tsa lisebelisoa le IoT hang-hang li tla kelellong);
Mohlala: data ea mocheso oa moea e hloka ho fetisetsoa konteraka e bohlale. U ka nka data ho tsoa Marang-rang ka "software oracle", kapa ho tsoa ho sensor ea IoT ka "hardware oracle". *IoT

Ka linako tse ling ho sebelisoa lipolelo tsa tumellano. Lipuo tse 'maloa li amohela data ka boinotšing, ebe li sebelisa algorithm ho fumana sephetho.
Mohlala oa hore na ke hobane'ng ha sena se hlokahala: li-oracle tsa 3 li fumana tekanyo ea BTC / USD ho tloha Binance, BitMex le Coinbase, 'me li fetisetsa boleng bo tloaelehileng e le tlhahiso. Sena se lokisa liphapang tse nyane lipakeng tsa phapanyetsano.

Ha u bua ka li-oracle le ts'ebetsong ea tsona, motho a ke ke a iphapanyetsa Web3, mohopolo oo ba o qapiloeng.

Protocol ea Band
Band Protocol e sebetsa ho algorithm ea tumellano ea dPoS () le bafani ba data ba na le boikarabelo ba ho tšepahala ka chelete, eseng feela botumo.
Ho na le mefuta e meraro ea basebelisi tikolohong ea projeke:
- Bafani ba data ba sebetsang ka boikemelo ho fetisetsa data ka mokhoa o sireletsehileng ho tsoa ka ntle ho blockchain ho blockchain. Batho ba nang le matšoao ba becha ho bafani ba data ho ba fa tokelo ea ho fana ka data ho protocol.
- Baetsi ba DApp ba lefang litefiso tse nyane ho sebelisa oracle.
- Bats'oari ba li-token ba voutelang bafani ba data. Ka ho vouta ka li-tokens tsa bona bakeng sa mofani, ba fumana moputso ho chelete e lefuoang ke dApps.
Har'a lipolelo tse fanoang ke Band ka ntle ho lebokose: nako ea sefofane / nako ea ho lula, 'mapa oa boemo ba leholimo, litefiso tsa cryptocurrency, khauta le litekanyetso tsa thepa, tlhahisoleseding e mabapi le li-block tsa Bitcoin, theko ea khase e tloaelehileng, palo ea phapanyetsano ea li-crypto, jenereithara ea nomoro e sa reroang, Yahoo Finance, HTTP.
