I kekahi kakahiaka ua ʻike au i kahi ʻatikala e pili ana ma ka Waves platform blockchain.
Ua maopopo ke kiʻi holoʻokoʻa, akā ʻaʻole i maopopo ke ʻano hoʻokō kikoʻī. ʻO kekahi mau code, pūlima, he aha, ma hea, no ke aha?
Nui nā kūkākūkā me ka mea kākau o ka ʻōlelo aʻoaʻo, ma muli o ka hopena, ua hiki ke hoʻohui i ka logic kiʻi (hoʻokō ʻia ma PHP) me kahi algorithm no ka loaʻa ʻana o kahi helu maʻamau.
- I ka hoʻomaka ʻana o ka hoʻokūkū/puni, noi mākou i ka hapa mua o ke code (R-code) mai ka ʻōlelo aʻoaʻo.
I kēia manawa, ʻaʻohe ʻike e pili ana i ka helu o nā mea pāʻani, ka helu o nā wahi makana, ka nui o nā uku makana, a i ʻole ke ola ʻana o ka loteri ma ka laulā. ʻO ka ʻōlelo aʻoaʻo, ma o ke kālepa ʻana, hoʻopuka i kahi code random pilikino, a laila hiki ke hoʻohana ʻia i hoʻokahi wale nō a na ka poʻe i noi. Ma ke ala, hiki ke "kūʻai" ʻia ka R-code (ʻo ia hoʻi ke kumukūʻai o ke kālepa noi + uku i ka ʻōlelo aʻoaʻo no ka pane pane ʻana, ʻo ia ka nui o $ 0.015 ma ka helu o kēia manawa, ua hoʻopuka ʻia ke code me ka uku ʻole. ) i mau manawa ma mua, i ʻole e kali i ka loaʻa ʻana o ka pane pane ma hope. Ua hana au i kahi mea hoʻopaʻa paʻa i hoʻonui mau ʻia ma ka waihona.
- ʻO ka hoʻokūkū maʻamau he 60 mau poloka o ka Waves platform blockchain, i kēia manawa ma kahi o 1 hola. Manaʻo ʻia ka hoʻokūkū ʻana a pani ʻia inā ma hope o 60 mau poloka aia ʻelua mau tikiki i loko, inā ʻaʻole e hoʻonui ʻia ka manawa hana hoʻokūkū no nā poloka 60 e hiki mai ana.
- Ma hope koke iho o ka pau ʻana o ka hoʻokūkū, hana mākou a hoʻouna i kahi kālepa lā (uku mākou i ke kōmike ma kahi o $0.005 no ia mea), inā pono, he nui, kahi i hoʻopaʻa ʻia ai nā kūlana āpau o ke kiʻi a me kahi papa inoa o nā mea pāʻani (tickets) mai laila mākou e koho ai i nā mea lanakila.
- I kēia pae, ua loaʻa iā mākou ka ʻāpana mua o ke code (R-code) me ka ID lā kūʻai (TXID). Hoʻouna mākou iā lākou no ke kau inoa ʻana i ka ʻōlelo aʻoaʻo ma ke ʻano o ka concatenation (R-code + TXID), uku hou mākou i kahi komisina + uku. Nānā ka ʻōlelo aʻoaʻo i ka ʻikepili i loaʻa no ka ʻokoʻa a me ke ʻano, a ma ka pane e hoʻouna mai iā mākou i ka ʻāpana ʻelua o ke code (S-code) ma ka format sha256, ʻo ia ka wahi hoʻomaka no ka mea hoʻomohala helu maʻamau.
- No ka loaʻa ʻana o kahi helu maʻamau e hōʻike i ka helu kaʻina o ka tiketi lanakila, hoʻololi mākou i ka S-code mai ka ʻikepili binary sha256 i kahi hōʻike hexadecimal (HEX). A laila mai ke kaula HEX i loaʻa, loaʻa iā mākou kahi helu. Loaʻa iā mākou ke koena o ka puʻunaue ʻana i ka helu i loaʻa i ka helu o nā tiketi (all_tickets) a hoʻohui i ka 1 i ka hopena (e kiʻi i ka helu 1 ma mua o all_tickets). ʻO ka hopena, loaʻa iā mākou ka helu serial o ka mea lanakila.
- Inā, e like me nā kūlana o ke kaha kiʻi, he nui nā mea lanakila, a laila e hana hou mākou i nā hana mua i ka nui e like me ka helu o nā wahi makana. I kēia hihia, i kēlā me kēia manawa mākou e wehe mai ka papa inoa i kahi tiketi i lanakila mua a hoʻemi i nā all_tickets e 1, a ma kahi o S-code mākou e hōʻike i ka helu mua i loaʻa.
E nānā kākou i kekahi laʻana maoli, hoʻokūkū No. 119:
Huina 7 tikiki (all_tickets)
ʻO ke kumu kūʻai he 50 mau kālā (Bet)
Uku pāʻani 10% (Uku)
E like me nā kūlana o ka hailona, 30% hele i ke kālā makana, i.e. i kēia hihia, pono e loaʻa i nā tiketi 2 kahi makana, ʻo ka nui o ia mea i helu ʻia e like me ke kumu (Bet*all_tickets-Fee)/2.
1. Loaʻa iā R-code:
2. Ma hope o ka pau ʻana o ka hoʻokūkū, loaʻa iā mākou kahi papa inoa o nā tiketi ma ke ʻano o nā pālua: helu + helu wahi (ka helu o ka ʻeke kālā i uku ʻia no ke komo ʻana i ka hoʻokūkū). E ʻoluʻolu e hiki ke hana hou ʻia nā ʻōlelo, ʻo ia hoʻi ua kūʻai kekahi mea komo i nā tiketi i hoʻokahi hoʻokūkū; ʻaʻole pāpā ʻia kēia e nā lula.
Hoʻouna ʻia ka lā kūʻai:
3. Noi ia S-code: me ka manaʻo (R-code + TXID):

4. Loaʻa iā S-code:
5. Hoʻoholo ʻia ka poʻe lanakila.

ʻO ka hopena, loaʻa iā mākou kahi hoʻopaʻa ʻana i kēlā me kēia pae o ke kaʻina hana kiʻi makana ma ka blockchain me ka hiki ke nānā iā ia i kēlā me kēia manawa. Aneane hiki ʻole i ka mea hoʻonohonoho ke hoʻoponopono i nā hopena; ma ka liʻiliʻi, ʻaʻole hiki ke hana ʻia me ka ʻike ʻole ʻia.
