Kulesi sihloko ngizokhuluma ngokuthi sizame kanjani ukwakha indawo yokuqasha isithuthuthu ezinkontilekeni ezihlakaniphile nokuthi kungani besisadinga isevisi emaphakathi.
Konke kwaqala kanjani
NgoNovemba 2018, sabamba iqhaza ku-hackathon enikezelwe ku-inthanethi Yezinto kanye ne-blockchain. Ithimba lethu likhethe ukwabelana ngesikuta njengombono njengoba sine-scooter evela kumxhasi wale hackathon. I-prototype yayibukeka njengohlelo lokusebenza lweselula olukuvumela ukuthi uqale isikuta nge-NFC. Ngokombono wokumaketha, lo mbono usekelwe indaba “emayelana nekusasa eliqhakazile” ene-ecosystem evulekile lapho noma ubani engaba umqashi noma umnikazi wendawo, konke ngokusekelwe kuzinkontileka ezihlakaniphile.
Ababambiqhaza bethu bawuthande ngempela lo mbono, futhi banquma ukuwuguqula ube yisibonelo ukuze uboniswe emibukisweni. Ngemuva kwemibhikisho eminingana eyimpumelelo e-Mobile World Congress kanye ne-Bosch Connected World ngo-2019, kwanqunywa ukuthi kuhlolwe ukuqashwa kwe-scooter nabasebenzisi bangempela, abasebenzi baseDeutsche Telekom. Ngakho-ke saqala ukuthuthukisa i-MVP egcwele.
Blockchain ngezinduku
Ngibona kungafanelekile ukuchaza ukuthi uyini umehluko phakathi kwephrojekthi ezokhonjiswa esiteji naleyo ezosetshenziswa abantu bangempela. Ezinyangeni eziyisithupha kwadingeka siguqule lesi sibonelo esingahluziwe sibe into efanelekayo umshayeli wendiza. Futhi-ke saqonda ukuthi "ubuhlungu" busho ukuthini.
Ukuze senze isistimu yethu ihlukaniswe futhi ivuleke, sinqume ukusebenzisa izinkontileka ezihlakaniphile ze-Ethereum. Ukukhetha kuwele kule nkundla yezinsizakalo eziku-inthanethi ezinwetshiwe ngenxa yokuduma kwayo kanye nekhono lokwakha uhlelo lokusebenza olungenaseva. Sahlela ukwenza iphrojekthi yethu ngale ndlela elandelayo.
Kodwa, ngeshwa, inkontileka ehlakaniphile iyikhodi eyenziwa umshini obonakalayo ngesikhathi sokuthengiselana, futhi ayikwazi ukufaka esikhundleni seseva egcwele. Isibonelo, inkontileka ehlakaniphile ayikwazi ukwenza izenzo ezilindile noma ezihleliwe. Kuphrojekthi yethu, lokhu akusivumelanga ukuthi sisebenzise isevisi yokuqasha ngomzuzu ngamunye, njengoba kwenza izinsizakalo eziningi zesimanje zokwabelana ngezimoto. Ngakho-ke, sidonse imali ye-crypto kumsebenzisi ngemva kokuqeda umsebenzi ngaphandle kokuqiniseka ukuthi unemali eyanele. Le ndlela yamukeleka kuphela kumshayeli wangaphakathi futhi, yebo, yengeza izinkinga lapho uklama iphrojekthi yokukhiqiza ephelele.
Okungezwe kukho konke okungenhla wukubamanzi kwenkundla ngokwayo. Isibonelo, uma ubhala inkontileka ehlakaniphile enomqondo ohlukile kumathokheni we-ERC-20, uzohlangabezana nezinkinga zokusingatha amaphutha. Ngokuvamile, uma okokufaka kungalungile noma izindlela zethu zingasebenzi kahle, sithola ikhodi yephutha njengempendulo. Endabeni ye-Ethereum, asikwazi ukuthola lutho ngaphandle kwenani legesi elisetshenziswe ukwenza lo msebenzi. Igesi wuhlobo lwemali okufanele lukhokhelwe uma kwenziwa izinto nezibalo: uma imisebenzi eminingi kukhodi yakho, uzokhokha kakhulu. Ngakho-ke ukuze uqonde ukuthi kungani ikhodi ingasebenzi, uqala uyihlole ngokulingisa wonke amaphutha angenzeka kanye ne-hardcode igesi echithwe njengekhodi yephutha. Kodwa uma ushintsha ikhodi yakho, lokhu kuphatha iphutha kuzophuka.
Ngaphezu kwalokho, cishe akunakwenzeka ukudala uhlelo lokusebenza lweselula olusebenza ne-blockchain ngokwethembeka, ngaphandle kokusebenzisa ukhiye ogcinwe endaweni ethile efwini. Nakuba ama-wallet athembekile ekhona, awanikezi ngezindawo zokungena zokusayina okwenziwayo kwangaphandle. Lokhu kusho ukuthi ngeke ubone uhlelo lokusebenza lwendabuko ngaphandle kokuthi unesikhwama se-crypto esakhelwe ngaphakathi, abasebenzisi abangeke bathembele kuso (ngingeke ngithembele). Ngenxa yalokho, nathi kwadingeka sinqamule ekhoneni lapha. Izinkontileka ezihlakaniphile zalethwa kunethiwekhi yangasese ye-Ethereum, futhi isikhwama sasisekelwe efwini. Kodwa ngaphandle kwalokhu, abasebenzisi bethu bahlangabezane nazo zonke "izinto ezijabulisayo" zezinsizakalo ezihlukaniswe ngendlela yokulinda isikhathi eside ngenxa yokwenziwe izikhathi ezimbalwa ngeseshini yokuqasha.
Konke lokhu kusiholela kulesi sakhiwo. Vuma, kuhluke kakhulu kulokho ebesikuhlelile.
I-Ace emgodini: I-self-Sovereign Identity
Awukwazi ukwakha isistimu ehlukaniswe ngokuphelele ngaphandle kobunikazi obuhlukaniselwe. I-Self-Sovereign Identity (SSI) ibophezelekile kule ngxenye, ingqikithi yayo ukuthi ulahle umhlinzeki kamazisi ophakathi nendawo (IDP) futhi usabalalise yonke idatha nesibopho sayo kubantu. Manje umsebenzisi unquma ukuthi iyiphi idatha ayidingayo nokuthi uzokwabelana nobani. Lonke lolu lwazi lutholakala kudivayisi yomsebenzisi. Kodwa ngokushintshana sizodinga uhlelo oluhlukaniselwe ukugcina ubufakazi be-cryptographic. Konke ukuqaliswa kwesimanje komqondo we-SSI kusebenzisa i-blockchain njengesitoreji.
"Kuhlangene ngani lokhu ne-ace emgodini?" - uyabuza. Sethule insizakalo yokuhlolwa kwangaphakathi kubasebenzi bethu eBerlin naseBonn, futhi sahlangabezana nobunzima obufana nezinyunyana zabasebenzi baseJalimane. EJalimane, izinkampani azivunyelwe ukuqapha ukunyakaza kwabasebenzi, futhi izinyunyana zilawula lokhu. Le mikhawulo iqeda ukugcinwa endaweni eyodwa kwedatha kamazisi wabasebenzisi, njengoba kulokhu sizokwazi indawo yezisebenzi. Ngesikhathi esifanayo, asikwazanga ukuzibamba ngaphandle kokuzihlola ngenxa yamathuba okuntshontshwa kwama-scooters. Kodwa ngenxa ye-self-Sovereign Identity, abasebenzisi bethu basebenzise isistimu ngokungaziwa, futhi isikuta ngokwaso sahlola ilayisense yabo yokushayela ngaphambi kokuqala ukuqasha. Ngenxa yalokho, sigcine amamethrikhi omsebenzisi angaziwa; besingenawo amadokhumenti noma idatha yomuntu siqu: konke bekuqukethwe kumadivayisi abashayeli ngokwabo. Ngakho, sibonga i-SSI, isixazululo senkinga kuphrojekthi yethu sase silungile nangaphambi kokuba sivele.
Idivayisi inginikeze izinkinga
Asizange sisebenzise I-Self-Sovereign Identity ngokwethu, njengoba idinga ubuchwepheshe ku-cryptography kanye nesikhathi esiningi. Kunalokho, sasizakala ngomkhiqizo wozakwethu be-Jolocom futhi sahlanganisa isikhwama sabo semali kanye nezinsizakalo endaweni yethu. Ngeshwa, lo mkhiqizo unesici esisodwa esibalulekile: ulimi oluyinhloko lokuthuthukisa i-Node.js.
Lesi sitaki sobuchwepheshe sikhawulela kakhulu ukukhetha kwethu kwehadiwe eyakhelwe ku-scooter. Ngenhlanhla, ekuqaleni kwephrojekthi, sakhetha i-Raspberry Pi Zero, futhi sasebenzisa ngokunenzuzo zonke izinzuzo ze-microcomputer egcwele. Lokhu kusivumele ukuthi sisebenzise i-Node.js enkulu kusikuta. Ngaphezu kwalokho, sithole ukuqapha nokufinyelela okukude nge-VPN sisebenzisa amathuluzi enziwe ngomumo.
Ekuphethweni
Naphezu kwabo bonke “ubuhlungu” nezinkinga, iphrojekthi yaqalwa. Akuwona wonke owasebenza njengoba sasihlelile, kodwa kwakungenzeka ngempela ukugibela ama-scooters ngokuwaqasha.
Yebo, senze amaphutha amaningana lapho siklama izakhiwo ezingasivumeli ukuthi senze insizakalo ihlukaniseke ngokuphelele, kodwa noma ngaphandle kwala maphutha besingeke sikwazi ukudala inkundla engenaseva. Kuyinto eyodwa ukubhala enye i-crypto-pyramid, futhi okunye ukubhala insizakalo egcwele lapho udinga ukusingatha amaphutha, ukuxazulula amacala emingcele futhi wenze imisebenzi elindile. Asethembe ukuthi amapulatifomu amasha asanda kuvela azovumelana nezimo futhi asebenze.
