Nezve blockchain oracles uye zvishoma nezveWeb3

Parizvino, blockchains akasarudzika zvakanyanya kubva kune ekunze zvinyorwa zveruzivo - zvese zviri pakati zviwanikwa uye mamwe blockchains. Kuve nechokwadi chekuti ma blockchains akasiyana anowirirana uye nyore kuchinjanisa data pakati pavo (uye nezviwanikwa zvekunze), maoreki anogona kushandiswa.

Chii chinonzi zvirevo

Oracle isystem inogamuchira uye inosimbisa zviitiko kubva kunze kwe blockchain uye inoendesa iyi data kune blockchain kuti ishandiswe mumakondirakiti akangwara (kana zvinopesana). MaOracles akakosha kune akangwara zvibvumirano nekuti akangwara makondirakiti anotemerwa zvakanyanya. Ruzivo runofanirwa kupinda muchibvumirano chakangwara kuburikidza neimwe chiteshi chinogona kusimbisa chokwadi chayo.

Kune akati wandei marudzi ezvirauro anopa imwe kana imwe mhando yekutaurirana:

• software - gamuchira data kubva kuInternet kana kubva kune mamwe blockchains;
• Hardware - gamuchira data kubva kune akasiyana masensa (RFID ma tag, imba yakangwara; pachangu, maapplication mune Logistics uye IoT anobva auya mupfungwa);

  Muenzaniso: data yekushisa kwemhepo inoda kuendeswa kune smart kontrakiti. Iwe unogona kutora data kubva paInternet kuburikidza nesoftware oracle, kana kubva kuIoT sensor kuburikidza nehardware oracle. *IoT Indaneti yezvinhu.

• inouya - kubva kunze kwe blockchain kupinda muchibvumirano chakangwara;
• kubuda - kubva pachibvumirano chakangwara kune imwe sosi;

Mazwi ekubvumirana dzimwe nguva anoshandiswa. Maoreki akati wandei anogashira data, uyezve shandisa imwe algorithm kuona zvinobuda.

Muenzaniso wekuti nei izvi zvichidiwa: 3 oracles inogamuchira BTC/USD chiyero kubva kuBinance, BitMex uye Coinbase, uye inotumira avhareji kukosha sekubuda. Izvi zvinogadzirisa kusawirirana kudiki pakati pekuchinjana.

Web3

Paunenge uchitaura nezve zvirevo uye mashandisirwo azvo, munhu haagone kufuratira Web3, iyo pfungwa yavakagadzirirwa. Webhu3 pakutanga yaive zano rewebhu semantic, uko saiti yega yega inoiswa metadata yekuvandudza kudyidzana nemainjini ekutsvaga. Nekudaro, iyo pfungwa yemazuva ano yeWeb3 inetiweki ine dApps. Uye zvikumbiro zvakaiswa munzvimbo inoda maoracles.

Zvinogoneka (uye, mune dzimwe nguva, zvinodikanwa) kugadzira chirevo iwe pachako, asi kune mamwe mashura anowanzoshandiswa (semuenzaniso, jenareta yenhamba isina kujairika), saka zvinodhura-zvinodhura kushandisa mapurojekiti ezvinyorwa. Iwo maviri makuru (parizvino) mapurojekiti ari kugadzira zvirevo ndeaya: bhendi и Chainlink.

Bumbiro Protocol

Band Protocol inomhanya pane dPoS kubvumirana algorithm (chii ichochi?) uye vanopa data vane basa rechokwadi nemari, kwete mukurumbira chete.

Kune marudzi matatu evashandisi muprojekiti ecosystem:

• Vanopa data vanoshanda vakazvimiririra kuendesa zvakachengeteka data kubva kunze kwe blockchain kuenda ku blockchain. Token holders vanobheja kune vanopa data kuti vavape kodzero yekuendesa data kune protocol.
• Vagadziri veDApp vanobhadhara mari shoma yekushandisa iyo oracle.
• Band token holders vanovhotera vanopa data. Nekuvhota nezviratidzo zvavo kune mupi, vanowana mubairo kubva pamari yakabhadharwa nedApps.

Pakati pezvinyorwa zvinopihwa neBand kunze kwebhokisi: kusimuka kwendege / nguva dzekumhara, mepu yemamiriro ekunze, cryptocurrency mitengo, goridhe uye stock mitengo, ruzivo nezve Bitcoin zvidhinha, avhareji mutengo wegasi, mavhoriyamu ekutsinhana kwecrypto, jenareta nhamba, Yahoo Finance, HTTP. Status Code .

Nenzira, pakati pevatengesi veBand ndiyo ine mukurumbira venture fund Sequoia и Binance.

Chainlink

Kazhinji, Chainlink neBand zvakafanana zvakanyanya - zvese mukugadzirisa zvigadziriso uye mukugona kwekusimudzira. Chainlink iri nyore kushandisa, hapana kuvhota kune vanopa ruzivo, uye Bhendi rinochinjika nekuti rinoshandisa. Cosmos SDK uye iri 100% yakavhurika sosi.

Parizvino, Chainlink inonyanya kufarirwa, neGoogle Cloud, Binance, Matic Network uye Polkadot pane rondedzero yevashandi veprojekiti. Chainlink zvakare yakatarisana nezvirevo zvebhora Defi, iyo zvino iri kukura nokukurumidza.

Zviwanikwa zvine data rinogona kuwanikwa kuburikidza nechirevo kubva kuChainlink.

mhedziso

Oracles ipfungwa yakanaka yekuwana data kubva pakati pezviwanikwa pa blockchain, uye ini ndichave ndakatarisa kukura kwayo zvakanyanya. Nekudaro, kana isu tikataura nezve kuwirirana kunoenderana kweakasiyana blockchains, kune dzimwe mhinduro, zvinosanganisira parachains (inotonyanya kuvimbisa tekinoroji uye musoro wepositi yangu inotevera).

Kune avo vanoda kuchera zvakadzika: Band Docs, Chainlink Docs.
