Zimanenedwa kuti protocol ya Umbra idapangidwa ndi Matt Solomon ndi Ben DiFrancesco kwa HackMoney 2020 pafupifupi hackathon, ndipo ikupezeka pa Ethereum Ropsten testnet.
Amagwiritsidwa ntchito chiyani?kungonena kuti:

"Ndi adilesi yosaoneka, wolipira amatha kutumiza zizindikiro za ETH kapena ERC20 ku adilesi yoyendetsedwa ndi wolandila, ndipo kupatula mbali zonse ziwiri, palibe gulu lachitatu lomwe lingadziwe yemwe wolandilayo ndi."

Pa unyolo, kugulitsako kumawoneka ngati kumangotumizidwa ku adilesi yosagwiritsidwa ntchito pa intaneti ya Ethereum.

Chithunzi: Onani zochitika za ETH pogwiritsa ntchito protocol ya Umbra pa Etherscan.Pa unyolo, adilesi yosawoneka ikuwoneka ngati adilesi ya EOA yanthawi zonse.

Kunja kwa tcheni, wotumizayo wagwiritsa ntchito ENS kupanga adilesi yatsopano kudzera pa kiyi yapagulu yoperekedwa ndi wolandila.Mwa kubisa zomwe zimagwiritsidwa ntchito popanga adilesi, ndipo kudzera mu mgwirizano wanzeru wa Umbra, wotumizayo atha kudziwitsa wolandirayo kuti watumiza ndalamazo ku adilesi yatsopano yosawoneka.Ndi wolandira yekhayo yemwe angapange kiyi yachinsinsi yofunikira kuti atenge ndalama.

Pogwiritsa ntchito netiweki ya Gas Station ndi Uniswap, Umbra imalola ochotsa ndalama kuti agwiritse ntchito ma tokeni omwe amalandira kuti alipire gasi.Izi zimapewa kufunikira kogwiritsa ntchito ETH kulipira ma adilesi osawoneka musanatenge ndalama.
Kusiyana pakati pa Umbra ndi Tornado Cash

Kodi pali kusiyana kotani pakati pa Umbra ndi Tornado Cash yomwe Vitalik amatchula nthawi zambiri?

Mwachidule, Tornado Cash ndi chosakanizira chandalama chomwe chimagwiritsa ntchito ziro-chidziwitso.Mukayikamo ndalama ndikudikirira kuti ena achite zomwezo, mutha kugwiritsa ntchito maumboni anu kuti muchotse katundu.Zimakhazikika mu chosakanizira, kotero ulalo pakati pa adilesi yoyambira ndi adilesi yochotsera wasweka.

Protocol ya Umbra imagwiritsidwa ntchito polipira pakati pa mabungwe awiri, ndipo imabwera ndi malonda osiyanasiyana achinsinsi (ndiko kuti, njira zosiyanasiyana zimaganiziridwa).Umbra sikuphwanya ulalo pakati pa ma adilesi otumiza ndi olandila, koma imapangitsa Maulalo kukhala opanda tanthauzo.Aliyense akhoza kudziwa adilesi yomwe ndalama zimatumizidwa, koma sangadziwe yemwe akuwongolera adilesiyo.

Kuphatikiza pa izi, protocol ya Umbra ilinso ndi zinthu zina zosangalatsa kwambiri.Mwachitsanzo, imagwiritsa ntchito mpweya wocheperako chifukwa sichifuna ukadaulo waukadaulo waukadaulo wamakina otsimikizira.Zochita zonse ndizosavuta kusamutsidwa.Kuphatikiza apo, imalola ETH ndi zizindikiro zilizonse za ERC20 kusamutsidwa mwachinsinsi, simuyenera kudalira gulu lalikulu losadziwika.

Kufotokozera kwa mfundo yogwirira ntchito ya Umbra protocol

Pomaliza, lankhulani mwachidule momwe protocol ya Umbra imagwiritsidwira ntchito:

Wogwiritsa amatumiza uthenga womwe wasainidwa ku zolemba za ENS kuti awonetse kiyi yawo yapagulu ya Umbra.Kiyi yapagulu iyi idachokera ku kiyi yachinsinsi yomwe idapangidwira Umbra.
Woperekayo amagwiritsa ntchito kiyi yapagulu iyi, kuphatikiza deta yopangidwa mwachisawawa, kenako ndikupanga adilesi yatsopano "yosaoneka".
Woperekayo amagwiritsa ntchito kiyi yapagulu ya wolandilayo kuti asungire deta mwachisawawa.
Woperekayo amatumiza ndalamazo ku adilesi yotetezedwa ndikutumiza uthenga wobisika ku mgwirizano wanzeru wa Umbra.Mgwirizanowu umawulutsa uthenga wobisika ngati chochitika.
Wolandira amasanthula uthenga wobisika womwe umafalitsidwa ndi protocol ya Umbra mpaka utapeza uthenga womwe ungathe kusindikizidwa ndi kiyi yachinsinsi.
Wolandira amagwiritsa ntchito zomwe zili mu uthenga wobisika kuphatikiza kiyi yawo yachinsinsi kuti apange kiyi yachinsinsi ya adilesi yosawoneka.
Wolandirayo amagwiritsa ntchito chinsinsi chachinsinsi cha adiresi yosaonekayo kuti asayine ntchito yochotsa ndalama ndikutumiza ETH kapena chizindikiro ku adiresi yomwe akufuna.
Njira inanso ndikuti ntchito yochotsamo imawulutsidwa kudzera pa Gas Station network transaction relayer, kupewa kufunikira kopereka ndalama za ETH kuti mupeze adilesi yosaoneka ya chizindikirocho.Mgwirizano wa Umbra umasinthanitsa ma tokeni kudzera ku Uniswap kuti alipire gasi ku GSN relayers.
Kuyambira pano, protocol ya Umbra ikadali pagawo loyesa pa Ropsten testnet.Malinga ndi Ben DiFrancesco, akukonzekera kukonza protocol ya Umbra ndipo posachedwa adzakhazikitsidwa pa mainnet Ethereum.Ntchito yawo yayikulu ndikuwonetsetsa chitetezo cha mgwirizano.Zimakhudza chitetezo cha ndalama za ogwiritsa ntchito.
