Tim Berners-Lee munguva pfupi yapfuura yakazivisa sarudzo yekushandura yakatarwa iyo inotsanangura zviziviso zvakatemerwa zveWebhu (NDAKAITA, Decentralized Identifier), mumamiriro ezvinhu anokurudzirwa, zvichibvisa kupokana kwakasimudzwa neGoogle neMozilla.
Iyo yakatarwa DID inosvitsa rudzi rutsva rwezviziviso zvepasi rose izvo chete hazvina kubatanidzwa kune ega ega masangano uye masevhisi, senge domain registrars uye zvitupa zvitupa. Chiziviso chinogona kunge chakabatana nechishandiso chisingaverengeki uye chakagadzirwa nemasisitimu anovimbwa nemuridzi wezvekushandisa.
Identifier Authentication inoshandisa humbowo hwehuchokwadi hwevaridzi hunobva pane cryptographic nzira, semasaini edhijitari. Iyo yakatarwa inobvumira nzira dzakasiyana dzekugovera kutonga uye kudzoreredza ruzivo rwekuzivikanwa, kusanganisira blockchain-yakavakirwa nzira.
Mafomati eiyo URI itsva akaumbwa se "did:method:unique_identifier", apo "wakaita" panodudza hurongwa hutsva hweURI, "nzira" inoratidza mabatirwo anoitwa chiziviso, uye "unique_identifier" inzira-yakanangana nezviwanikwa.
Munda une nzira inodoma zita rebasa rinoshandiswa kuchengetedza data rakasimbiswa, iyo inova nechokwadi chekusiyana kwechiziviso, chinotarisa chimiro chayo, uye chinopa kusungirirwa kwechiziviso kune chitubu chachakagadzirirwa. Iyo URI ine ID inoshandurwa kuita gwaro reJSON rine metadata inotsanangura chinhu chakumbirwa uye inosanganisira makiyi eruzhinji kuratidza muridzi.
Maitiro ekuita ari kunze kwechikamu cheiyo DID chiyero, inotsanangurwa mune yayo yakatarwa, uye inochengetwa mune yakaparadzana registry.
Iye zvino 135 nzira dzakataurwa zvichibva pane akasiyana blockchains, cryptographic algorithms, yakagovaniswa matekinoroji, decentralized dhatabhesi, P2P masisitimu, uye nzira dzekuzivikanwa. Zvakare zvinokwanisika kugadzira DID links pane centralized systems, semuenzaniso, iyo nzira yewebhu inobvumira echinyakare mazita ekugamuchira kuti asungwe (semuenzaniso, "did:web:example.com").
Zvipikiso zveGoogle zvine chekuita nekuparadzaniswa kweiyo yakatarwa kune yakajairika nzira ye decentralized identifiers yezvakatemerwa zvekupedzisira kushandiswa kwemaitiro, izvo zvisingabvumire kuongorora kurongeka kweiyo huru yekutsanangurwa pasina kudzidza kutsanangurwa kwemaitiro.
Kushambadza iyo huru yekumisikidza kana iyo nzira yekumisikidza isati yagadzirira kunoita kuti kudzokorora kuome, uye Google yakurudzira kuti kumiswa kweiyo DID kutsanangurwa kunomisikidzwa kudzamara dzimwe nzira dzakanakisa dzagadzirira kumisikidzwa, senge mukuita kwekumisikidza nzira, mapoinzi akajeka anogona. simuka izvo zvinoda kuti chirevo chikuru chipedziswe.
Kupokana kwaMozilla ndekwekuti iyo spec haina kutyaira zvakakwana, ichisiya dambudziko kudivi rekunyoresa nzira.
Nzira dzinopfuura zana dzakatove dzakatsanangurwa mune registry, dzakagadzirwa pasina hanya nekuenderana uye kubatana kweyakajairwa mhinduro. Mune chimiro chayo chemazuva ano, zvinokurudzirwa kugadzira nzira itsva yebasa rega rega, pane kuedza kugadzirisa nzira dziripo kuti dzienderane nezvido zvako.
Chinzvimbo cheW3C ndechekuti kumisikidzwa kweiyo DID yakatarwa, iyo inotsanangura kirasi itsva yakawedzera yekuzvizivisa uye syntax inosanganisirwa, inosimudzira kusimudzira nzira uye kubvumirana pakumisikidzwa kwenzira.
Mune fomu yazvino, kune humbowo hwakakwana hwekushandiswa kweiyo huru yekutsanangura kugadzirisa matambudziko izvo zviri kudiwa munharaunda inogadzira matekinoroji akasarudzika. Izvo zvinorongwa zvekushandiswa kwemaitiro hazvifanirwe kutongwa nekuenzanisa nehurongwa hutsva hwe URL, uye kusikwa kwenhamba yakawanda yenzira dzinogona kuonekwa sekuenderana nehwaro hwaro hwezvinodiwa nevagadziri.
Kugadziriswa kwedzimwe nzira kunoonekwa sebasa rakaoma, maererano nekuwana kubvumirana pakati pevagadziri, pane kuenzanisa pane imwe kirasi yezviziviso. Naizvozvo, kutorwa kwechirevo chakafanana kusati kwaitwa nzira kunoonekwa semhinduro inogona kukonzeresa kukuvadza kunharaunda iyo inoshandisa zviziviso zvakatemerwa.
Finalmente kana iwe uchifarira kuziva zvakawanda nezvazvo, unogona kutarisa iyo ruzivo mune inotevera chinongedzo.
