M'nkhaniyi ndilankhula za momwe tidayesera kupanga renti ya scooter yokhazikika pamakontrakitala anzeru komanso chifukwa chomwe timafunikirabe ntchito yapakati.
Momwe izo zinayambira
Mu Novembala 2018, tidatenga nawo gawo mu hackathon yoperekedwa ku intaneti ya Zinthu ndi blockchain. Gulu lathu lasankha kugawana njinga yamoto yovundikira ngati lingaliro popeza tinali ndi njinga yamoto yovundikira kuchokera kwa omwe amatithandizira. Mtunduwu umawoneka ngati foni yam'manja yomwe imakupatsani mwayi woyambitsa scooter kudzera pa NFC. Kuchokera pamalingaliro amalonda, lingalirolo linathandizidwa ndi nkhani ya "tsogolo lowala" ndi chilengedwe chotseguka kumene aliyense akhoza kukhala wobwereketsa kapena mwini nyumba, zonse kutengera mapangano anzeru.
Okhudzidwa athu adakonda kwambiri lingaliro ili, ndipo adaganiza zosintha kuti likhale fanizo kuti liwonetsedwe paziwonetsero. Pambuyo pa ziwonetsero zingapo zopambana pa Mobile World Congress ndi Bosch Connected World mu 2019, adaganiza zoyesa kubwereka kwa scooter ndi ogwiritsa ntchito enieni, ogwira ntchito ku Deutsche Telekom. Chifukwa chake tinayamba kupanga MVP yokwanira.
Blockchain pa ndodo
Sindikuganiza kuti ndizoyenera kufotokoza kusiyana komwe kulipo pakati pa polojekiti yomwe idzawonetsedwe pa siteji ndi yomwe idzagwiritsidwe ntchito ndi anthu enieni. M’miyezi isanu ndi umodzi tinafunikira kusandutsa chithunzithunzicho kukhala choyenerera munthu woyendetsa ndege. Ndiyeno tinamvetsa tanthauzo la “kuwawa”.
Kuti dongosolo lathu likhale lodziwika bwino komanso lotseguka, tinaganiza zogwiritsa ntchito mapangano anzeru a Ethereum. Chisankhocho chinagwera pa nsanja iyi ya ntchito zapaintaneti zomwe zimadziwika chifukwa cha kutchuka kwake komanso kuthekera kopanga pulogalamu yopanda seva. Tinakonza zoti tikwaniritse polojekiti yathu motere.
Koma, mwatsoka, mgwirizano wanzeru ndi kachidindo kamene kamachitidwa ndi makina enieni pa nthawi ya malonda, ndipo sangalowe m'malo mwa seva yodzaza. Mwachitsanzo, mgwirizano wanzeru sungathe kuchita zomwe zikuyembekezera kapena zomwe zakonzedwa. Mu ntchito yathu, izi sizinatilole kuti tigwiritse ntchito ntchito yobwereketsa mphindi imodzi, monga momwe ntchito zambiri zamakono zogawana magalimoto zimachitira. Chifukwa chake, tidabweza ndalama za crypto kuchokera kwa wogwiritsa ntchitoyo titamaliza ntchitoyo popanda kutsimikiza kuti anali ndi ndalama zokwanira. Njirayi ndi yovomerezeka kwa woyendetsa ndege wamkati ndipo, ndithudi, imawonjezera mavuto popanga pulojekiti yopangira zonse.
Zomwe zili pamwambazi ndizonyowa za nsanja yokha. Mwachitsanzo, ngati mulemba mgwirizano wanzeru wokhala ndi malingaliro osiyana ndi ma tokeni a ERC-20, mudzakumana ndi zovuta zowongolera zolakwika. Nthawi zambiri, ngati zolowetsazo zili zolakwika kapena njira zathu sizikuyenda bwino, timalandira khodi yolakwika poyankha. Pankhani ya Ethereum, sitingapeze china chilichonse kupatula kuchuluka kwa gasi wogwiritsidwa ntchito pochita ntchitoyi. Gasi ndi ndalama yomwe imayenera kulipidwa pochita zinthu ndi kuwerengera: ntchito zambiri mu code yanu, mudzalipira kwambiri. Kotero kuti mumvetse chifukwa chake kachidindoyo sikugwira ntchito, mumayesa kaye poyesa zolakwika zonse ndi hardcode mpweya womwe umagwiritsidwa ntchito ngati code yolakwika. Koma ngati musintha khodi yanu, kukonza zolakwika izi kutha.
Kuphatikiza apo, ndizosatheka kupanga pulogalamu yam'manja yomwe imagwira ntchito ndi blockchain moona mtima, osagwiritsa ntchito kiyi yosungidwa kwinakwake mumtambo. Ngakhale zikwama zowona mtima zilipo, sizimapereka mwayi wosaina zochitika zakunja. Izi zikutanthauza kuti simudzawona pulogalamu yachibadwidwe pokhapokha ngati ili ndi chikwama cha crypto chomangidwa, chomwe ogwiritsa ntchito sangakhulupirire (sindingakhulupirire). Chotsatira chake, tinayeneranso kudula ngodya apa. Mapangano anzeru adaperekedwa ku intaneti ya Ethereum payekha, ndipo chikwamacho chinali chokhazikika pamtambo. Koma ngakhale izi, ogwiritsa ntchito athu adakumana ndi "zosangalatsa" zonse zautumiki wokhazikika m'njira yodikirira kwanthawi yayitali kuti agulidwe kangapo pagawo lililonse lobwereketsa.
Zonsezi zimatifikitsa ku kamangidwe kameneka. Gwirizanani, ndizosiyana kwambiri ndi zomwe tinakonza.
Ace m’dzenje: Chidziwitso Chodzilamulira
Simungapange dongosolo logawika m'madera onse popanda kudziwika kuti ndi ndani. Self-Sovereign Identity (SSI) ndi amene ali ndi udindo pa gawoli, zomwe zimachititsa kuti mutulutse chizindikiritso chapakati (IDP) ndikugawa zonse ndi udindo wake kwa anthu. Tsopano wogwiritsa ntchito amasankha zomwe akufuna komanso kuti agawane ndi ndani. Zonse izi zili pa chipangizo cha wosuta. Koma pakusinthana tidzafunika dongosolo lokhazikika losunga umboni wa cryptographic. Kukhazikitsa kwamakono kwa lingaliro la SSI kumagwiritsa ntchito blockchain ngati yosungirako.
"Kodi izi zikugwirizana bwanji ndi ace mu dzenje?" - mumafunsa. Tidayambitsa ntchito yoyesa mkati mwa ogwira ntchito athu ku Berlin ndi Bonn, ndipo tidakumana ndi zovuta m'mabungwe aku Germany. Ku Germany, makampani amaletsedwa kuyang'anira mayendedwe a antchito, ndipo mabungwe amawongolera izi. Zoletsa izi zimathetsa kusungidwa kwapakati kwa zidziwitso za ogwiritsa ntchito, popeza apa titha kudziwa komwe antchito ali. Nthawi yomweyo, sitinachitire mwina koma kuwayang'ana chifukwa cha kuthekera kwakuti ma scooters abedwa. Koma chifukwa cha Kudzizindikiritsa Wodzilamulira, ogwiritsa ntchito adagwiritsa ntchito makinawa mosadziwika, ndipo scooter yokha idayang'ana laisensi yawo yoyendetsa isanayambe kubwereka. Zotsatira zake, tidasunga ma metrics osadziwika; tinalibe zolemba zilizonse kapena zambiri zaumwini: zonse zinali pazida za madalaivala okha. Chifukwa chake, chifukwa cha SSI, yankho la vuto la polojekiti yathu linali lokonzeka ngakhale lisanawonekere.
Chipangizocho chinandipatsa mavuto
Sitinagwiritse ntchito Kudzilamulira tokha, chifukwa zimafuna ukadaulo wa cryptography komanso nthawi yambiri. M'malo mwake, tinatengerapo mwayi pazogulitsa za Jolocom omwe timagwira nawo ntchito ndikuphatikiza chikwama chawo cham'manja ndi ntchito papulatifomu yathu. Tsoka ilo, mankhwalawa ali ndi vuto limodzi lalikulu: chilankhulo chachikulu chachitukuko ndi Node.js.
Tekinoloje iyi imachepetsa kwambiri kusankha kwathu kwa hardware yomangidwa mu scooter. Mwamwayi, kumayambiriro kwa ntchitoyi, tidasankha Raspberry Pi Zero, ndipo tidatengera mwayi pazabwino zonse zamakompyuta ang'onoang'ono. Izi zidatipangitsa kuti tizitha kuyendetsa Node.js pa scooter. Kuphatikiza apo, tidalandira kuyang'anira ndi mwayi wakutali kudzera pa VPN pogwiritsa ntchito zida zopangidwa kale.
Pomaliza
Ngakhale kuti "zowawa" zonse ndi mavuto, ntchitoyi inayambika. Sikuti zonse zidayenda momwe tidakonzera, koma zinali zotheka kukwera ma scooters powabwereka.
Inde, tinapanga zolakwika zingapo popanga zomangamanga zomwe sizinatilole kuti ntchitoyo ikhale yokhazikika, koma ngakhale popanda zolakwika izi sitikanatha kupanga nsanja yopanda seva. Ndi chinthu chimodzi kulemba crypto-piramidi ina, ndi zinanso kulemba ntchito yokwanira yomwe muyenera kuthana ndi zolakwika, kuthetsa milandu yamalire ndikuchita ntchito zomwe zikuyembekezera. Tikukhulupirira kuti nsanja zatsopano zomwe zatuluka posachedwa zidzakhala zosinthika komanso zogwira ntchito.
