Za momwe mungalembe ndikusindikiza mgwirizano wanzeru ku TON

Kodi nkhaniyi ikunena za chiyani?

M'nkhaniyi ndilankhula za momwe ndinachitira nawo mpikisano woyamba (wa awiri) wa Telegraph blockchain, sindinalandire mphotho, ndipo ndinaganiza zolemba zomwe ndakumana nazo m'nkhani kuti zisalowe m'kuiwalika ndipo, mwina, kuthandizira. wina.

Popeza sindinkafuna kulemba code abstract, koma kuti ndichite chinachake chogwira ntchito, chifukwa cha nkhaniyi ndinalemba mgwirizano wanzeru wa lottery yomweyo ndi webusaiti yomwe imasonyeza deta yanzeru ya mgwirizano kuchokera ku TON popanda kugwiritsa ntchito kusungirako kwapakati.

Nkhaniyi idzakhala yothandiza kwa iwo omwe akufuna kupanga mgwirizano wawo woyamba wanzeru ku TON, koma osadziwa komwe angayambire.

Pogwiritsa ntchito lottery monga chitsanzo, ndidzachoka pa kukhazikitsa chilengedwe mpaka kufalitsa mgwirizano wanzeru, kuyanjana nawo, ndikulemba webusaiti kuti ndilandire ndi kusindikiza deta.

Za kutenga nawo mbali pa mpikisano

October watha, Telegalamu adalengeza mpikisano wa blockchain ndi zilankhulo zatsopano Fift и FunC. Zinali zofunikira kusankha kulemba chilichonse mwa mapangano asanu omwe akufunsidwa. Ndinaganiza kuti zingakhale bwino kuchita chinachake chosiyana, kuphunzira chinenero ndi kupanga chinachake, ngakhale ine ndiribe kulemba china chilichonse m'tsogolo. Komanso, mutuwo nthawi zonse umakhala pamilomo.

Ndikoyenera kunena kuti ndinalibe chidziwitso chopanga makontrakitala anzeru.

Ndinalinganiza kutengamo mbali mpaka kumapeto kwenikweni kufikira nditakhoza ndiyeno kulemba nkhani yobwereza, koma ndinalephera nthaŵi yomweyo pa yoyamba. Ine analemba chikwama ndi ma signature ambiri FunC ndipo nthawi zambiri zinagwira ntchito. Ndinazitenga ngati maziko smart contract pa Solidity.

Panthawiyo, ndinkaganiza kuti zimenezi zinali zokwanira kuti nditengepo mphoto. Chifukwa cha zimenezi, pafupifupi 40 mwa otenga nawo mbali 60 anakhala opambana mphoto ndipo ine sindinali m’gulu lawo. Mwambiri, palibe cholakwika ndi izi, koma chinthu chimodzi chidandivutitsa. Pa nthawi yolengeza zotsatira, kuwunikanso mayeso a mgwirizano wanga sikunachitike, ndidafunsa omwe adalowa nawo pazokambirana ngati pali wina yemwe alibe, palibe.

Mwachiwonekere kumvetsera mauthenga anga, patatha masiku awiri oweruza adasindikiza ndemanga ndipo sindikumvetsabe ngati adaphonya mwangozi mgwirizano wanga wanzeru panthawi yoweruza kapena amangoganiza kuti zinali zoipa kwambiri moti sizikusowa ndemanga. Ndinafunsa funso patsambalo, koma sindinayankhe. Ngakhale kuti si chinsinsi amene anaweruza, ndinaona kuti sikoyenera kulemba mauthenga aumwini.

Nthawi yochuluka idagwiritsidwa ntchito kumvetsetsa, choncho adaganiza zolemba nkhani. Popeza palibe zambiri zambiri, nkhaniyi ithandiza kusunga nthawi kwa aliyense amene ali ndi chidwi.

Lingaliro la makontrakitala anzeru mu TON

Musanalembe chilichonse, muyenera kudziwa mbali yomwe mungayandikire chinthuchi. Chifukwa chake, tsopano ndikuwuzani magawo omwe dongosololi lili. Ndendende, ndi mbali ziti zomwe muyenera kudziwa kuti mulembe osachepera mtundu wina wa mgwirizano wogwira ntchito.

Tidzayang'ana pa kulemba mgwirizano wanzeru ndikugwira nawo ntchito TON Virtual Machine (TVM), Fift и FunC, kotero kuti nkhaniyi ili ngati kufotokozera za chitukuko cha pulogalamu yokhazikika. Sitingoganizira momwe nsanjayo imagwirira ntchito pano.

Zambiri za momwe zimagwirira ntchito TVM ndi chinenero Fift pali zolembedwa zabwino zovomerezeka. Pamene ndikuchita nawo mpikisano ndipo tsopano ndikulemba mgwirizano wamakono, nthawi zambiri ndinkatembenukira kwa iye.

Chilankhulo chachikulu chomwe ma contract anzeru amalembedwa ndi FunC. Palibe zolembedwa pa izo pakali pano, kotero kuti mulembe chinachake muyenera kuphunzira zitsanzo za mapangano anzeru ku chosungira boma ndi kukhazikitsa chinenero palokha kumeneko, kuphatikizapo mukhoza kuyang'ana zitsanzo za mapangano anzeru kuyambira awiri apitawa. mpikisano. Maulalo kumapeto kwa nkhani.

Tinene kuti talemba kale contract yanzeru FunC, pambuyo pake timapanga code kukhala Fift assembler.

Mgwirizano wanzeru wophatikizidwa uyenera kusindikizidwa. Kuti muchite izi muyenera kulemba ntchito mu Fift, yomwe idzatenge kachidindo kanzeru ndi magawo ena monga chothandizira, ndipo zotsatira zake zidzakhala fayilo yokhala ndi zowonjezera. .boc (lomwe limatanthauza "chikwama cha maselo"), ndipo, malingana ndi momwe timalembera, chinsinsi chachinsinsi ndi adiresi, zomwe zimapangidwa motsatira ndondomeko ya mgwirizano wanzeru. Mutha kutumiza kale magalamu ku adilesi ya mgwirizano wanzeru womwe sunasindikizidwebe.

Kuti musindikize mgwirizano wanzeru ku TON walandira .boc fayilo iyenera kutumizidwa ku blockchain pogwiritsa ntchito kasitomala wopepuka (zambiri pamunsimu). Koma musanasindikize, muyenera kusamutsa magalamu ku adilesi yopangidwa, apo ayi mgwirizano wanzeru sudzasindikizidwa. Pambuyo pofalitsa, mutha kuyanjana ndi mgwirizano wanzeru potumiza mauthenga kuchokera kunja (mwachitsanzo, pogwiritsa ntchito kasitomala wopepuka) kapena kuchokera mkati (mwachitsanzo, mgwirizano umodzi wanzeru umatumiza wina uthenga mkati mwa TON).

Tikamvetsetsa momwe code imasindikizidwira, zimakhala zosavuta. Timadziwa bwino zomwe tikufuna kulemba komanso momwe pulogalamu yathu idzagwirira ntchito. Ndipo polemba, timayang'ana momwe izi zagwiritsidwira ntchito kale pamakontrakitala anzeru omwe alipo, kapena timayang'ana pama code okhazikitsa Fift и FunC m'malo ovomerezeka, kapena yang'anani muzolemba zovomerezeka.

Nthawi zambiri ndimayang'ana mawu osakira pamacheza a Telegraph pomwe onse omwe adachita nawo mpikisano ndi ogwira ntchito pa Telegraph adasonkhana, ndipo zidachitika kuti pampikisanowo aliyense adasonkhana pamenepo ndikuyamba kukambirana za Fift ndi FunC. Lumikizani kumapeto kwa nkhaniyo.

Yakwana nthawi yochoka ku chiphunzitso kupita kukuchita.

Kukonzekera chilengedwe chogwirira ntchito ndi TON

Ndidachita zonse zomwe zidzafotokozedwe m'nkhani ya MacOS ndikuyiyang'ana kawiri mu Ubuntu 18.04 LTS pa Docker.

Chinthu choyamba muyenera kuchita ndi download ndi kukhazikitsa lite-client momwe mungatumizire zopempha ku TON.

Malangizo omwe ali patsamba lovomerezeka amafotokoza za kukhazikitsa mwatsatanetsatane komanso momveka bwino ndikusiya zambiri. Apa tikutsatira malangizowo, ndikuyika zodalira zomwe zikusowa panjira. Sindinapange pulojekiti iliyonse ndekha ndikuyika kuchokera ku Ubuntu repository (pa MacOS ndidagwiritsa ntchito brew).

Monga ndalembera pamwambapa, mgwirizano wanzeru womwe tikulemba ndi lottery.

Komanso, iyi si lottery yomwe muyenera kugula tikiti ndikudikirira ola, tsiku kapena mwezi, koma nthawi yomweyo yomwe wogwiritsa ntchito amasamutsira ku adilesi ya mgwirizano. N magalamu, ndipo nthawi yomweyo amachibwezera 2 * N magalamu kapena kutaya. Tipanga mwayi wopambana pafupifupi 40%. Ngati palibe magalamu okwanira olipira, ndiye kuti tiwona zomwe zikuchitikazo ngati zowonjezera.

Kuphatikiza apo, ndikofunikira kuti kubetcha kumawonedwa munthawi yeniyeni komanso m'njira yabwino, kuti wogwiritsa ntchitoyo amvetsetse ngati adapambana kapena adataya. Chifukwa chake, muyenera kupanga tsamba lomwe liziwonetsa kubetcha ndi zotsatira kuchokera ku TON.

Kulemba mgwirizano wanzeru

Kuti zikhale zosavuta, ndaunikira kachidindo ka FunC; pulogalamu yowonjezera ingapezeke ndikuyika mukusaka kwa Visual Studio Code; ngati mwadzidzidzi mukufuna kuwonjezera china, ndapangitsa kuti pulogalamu yowonjezerayi ipezeke poyera. Komanso, wina adapanga pulogalamu yowonjezera yogwira ntchito ndi Fift, mutha kuyiyikanso ndikuipeza mu VSC.

Tiyeni nthawi yomweyo tipange malo osungiramo momwe timapangira zotsatira zapakatikati.

Kuti moyo wathu ukhale wosavuta, tidzalemba mgwirizano wanzeru ndikuyesa kwanuko mpaka itakonzeka. Pambuyo pake tidzazisindikiza mu TON.

Mgwirizano wanzeru uli ndi njira ziwiri zakunja zomwe zingapezeke. Choyamba, recv_external() ntchito iyi imachitidwa pamene pempho la mgwirizano limachokera kudziko lakunja, ndiko kuti, osati kuchokera ku TON, mwachitsanzo, pamene ife tokha timapanga uthenga ndikutumiza kudzera mwa lite-client. Chachiwiri, recv_internal() apa ndi pamene, mkati mwa TON yokha, mgwirizano uliwonse umatanthawuza zathu. Muzochitika zonsezi, mutha kudutsa magawo ku ntchitoyi.

Tiyeni tiyambe ndi chitsanzo chosavuta chomwe chidzagwira ntchito ngati chisindikizidwa, koma palibe katundu wogwira ntchito mmenemo.

Osayiwala kusaina uthengawo ndi kiyi yanu yachinsinsi lottery.pk, yomwe idapangidwa kale popanga mgwirizano wanzeru. Nayi kudzipereka kofananira.

Kulandira zambiri kuchokera ku mgwirizano wanzeru pogwiritsa ntchito njira zopezera

Tsopano tiyeni tione mmene kuthamanga anzeru mgwirizano kupeza njira.

Yambitsani lite-client ndikuyendetsa kupeza njira zomwe tidalemba.

Tigwiritsa ntchito kasitomala ndikupeza njira zowonetsera zambiri zamakampani anzeru patsamba.

Kuwonetsa chidziwitso chamgwirizano wanzeru patsamba lawebusayiti

Ndinalemba tsamba losavuta ku Python kuti ndiwonetse deta kuchokera ku mgwirizano wanzeru m'njira yabwino. Pano sindikhalapo mwatsatanetsatane ndipo ndidzafalitsa malowa mu kudzipereka kumodzi.

Zopempha ku TON zimapangidwa kuchokera Python ndi thandizo lite-client. Kuti zitheke, tsambalo limayikidwa mu Docker ndikusindikizidwa pa Google Cloud. Lumikizani.

Kuyesera

Tsopano tiyeni tiyese kutumiza magalamu kumeneko kuti abwereze kuchokera chikwama. Timatumiza 40 magalamu. Ndipo tiyeni tichite mabetcha angapo kuti amveke bwino. Tikuwona kuti tsambalo likuwonetsa mbiri ya kubetcha, kuchuluka komwe kwapambana ndi zina zambiri zothandiza.

Tikuwonakuti tinapambana yoyamba, tinataya yachiwiri.

Pambuyo pake

Nkhaniyi idakhala yayitali kwambiri kuposa momwe ndimayembekezera, mwina ingakhale yayifupi, kapena mwina kwa munthu amene sadziwa chilichonse chokhudza TON ndipo akufuna kulemba ndikusindikiza mgwirizano wanzeru wosavuta komanso wokhoza kuyanjana nawo. izo. Mwina zinthu zina zikanatha kufotokozedwa mosavuta.

Mwinamwake mbali zina za kukhazikitsidwa zikanachitidwa bwino kwambiri ndi mokongola, koma zikanatenga nthawi yochuluka kwambiri kukonzekera nkhaniyo. N'zothekanso kuti ndinalakwitsa kwinakwake kapena sindinamvetse chinachake, kotero ngati mukuchita chinachake chachikulu, muyenera kudalira zolemba zovomerezeka kapena malo ovomerezeka ndi TON code.

Tiyenera kukumbukira kuti popeza TON mwiniwakeyo akadali mu gawo logwira ntchito lachitukuko, kusintha kungachitike kuti kuthyole njira iliyonse m'nkhaniyi (zomwe zinachitika pamene ndikulemba, zakonzedwa kale), koma njira yowonjezereka ndiyo. zokayikitsa kusintha.
