  • Ukuqina kuwulimi oluyinhloko lokuhlela izinkontileka ezihlakaniphile ku-Ethereum.
  • Izicelo zayo zifaka i-DeFi, NFTs, kanye nezinhlelo zokuvota ezihlukaniselwe abantu.
  • Ifinyeleleka kubahleli bezinhlelo abanolwazi lwangaphambili lwezilimi ezifana neJavaScript.
  • Amathuluzi afana ne-Remix enza kube lula ukuhlela nokusebenzisa izinkontileka ezihlakaniphile.

Uhlelo lokuqina

Ukuqina Iwulimi lokuhlela oluthole ukuhlobana okukhulu ekuthuthukisweni kwe izinkontileka smart kanye nezicelo ezihlukaniselwe phakathi blockchain kusuka ku-Ethereum. Nakuba ukusetshenziswa kwayo okuyinhloko kugxile ku-Ethereum, ikhona nakwamanye amanethiwekhi ahambisanayo ngenxa yokuguquguquka nokuvumelana nezimo. Idizayini yayo egxile entweni kanye nokufana kwayo nezilimi ezifana neJavaScript kuyenza ibe ithuluzi elifinyeleleka kubahleli bohlelo, nakuba ijika layo lokufunda lingaba yinkimbinkimbi kwabaqalayo ngaphandle kolwazi lohlelo lwangaphambili.

Kulesi sihloko, sizohlola ngokucophelela Konke odinga ukukwazi mayelana Solidity: kusukela kokuyisisekelo, izici zobuchwepheshe kanye nezinhlelo zokusebenza eziphawuleka kakhulu, kuya kumhlahlandlela wokuqala wesinyathelo ngesinyathelo kulabo abafisa ukuhlolisisa lolu limi oluthakazelisayo. Uma unentshisekelo emhlabeni wezinkontileka ezihlakaniphile, lesi sihloko senzelwe wena.

Iyini i-Solidity futhi isebenza kanjani?

Ukuqina kuwulimi lokuhlela izinga eliphakeme, eklanyelwe ngokukhethekile ukuhlela izinkontileka ezihlakaniphile, okuyizinhlelo ezizenzelayo ezigcinwe ku blockchain. Yakhiwe ngo-2014 ngabathuthukisi abakhulu bephrojekthi ye-Ethereum, njengo-Christian Reitwiessner no-Alex Beregszaszi.

Ikhodi yomthombo weSolidity ihlanganiswa ibe ikhodi, evumela ukwenziwa kwayo ngaphakathi kwe Umshini we-Ethereum Virtual Machine (EVM). Lokhu kunika amandla ukudalwa kwezinkontileka ezihlakaniphile ezenza ngokuzenzakalelayo izenzo ezichazwe ngaphambilini lapho izimo ezithile zifinyelelwa.

I-Ethereum Blockchain

Ezinye izici ezibalulekile ezichaza i-Solidity ingeyayo ukuthayipha okumile, umumo wento kanye nekhono layo lokuthola ifa nokusebenzisa kabusha ikhodi. Ngaphezu kwalokho, inamathuluzi okuqinisekisa ukuphepha nokusebenza kahle kwekhodi, njengokuphatha okuhlukile kanye Izindlela ze-GAS, esetshenziselwa ukuvimbela izihibe ezingapheli ezingase ziphahlaze inethiwekhi ye-Ethereum.

Izici eziyinhloko ze-Solidity

  • I-syntax efana ne-JavaScript: Lokhu kwenza ukufunda kube lula kubahleli bewebhu abanolwazi.
  • Okuqondiswe entweni: Ivumela idatha ukuthi imelwe ngezinto eziqukethe izibaluli ezithile nokuziphatha.
  • Ukuguqula ulimi oluphelele: Iyakwazi ukwenza noma iyiphi i-algorithm ehleliwe, inqobo nje uma izinsiza zanele.
  • Ukusekelwa kwemitapo yolwazi eyinkimbinkimbi nedatha: Lokhu kuyenza ifanelekele izinhlelo zokusebenza eziyinkimbinkimbi.

Ngaphezu kwalokho, i-Solidity ihlanganisa amathuluzi athuthukile njengokuhlanganisa amakhodi nokuhlakazwa, ukwenza lula imisebenzi efana nokucwaninga amabhuku kanye nokulungisa amaphutha ezinkontileka ezihlakaniphile.

Solidity Izicelo

Ukusetshenziswa okuyinhloko kwe-Solidity ukudala izinkontileka ezihlakaniphile ze-Ethereum blockchain, kodwa izicelo zayo zihlanganisa imikhakha efana nale:

  • Izimali Ezimisiwe (DeFi): Ukuthuthukiswa kwezinkundla zokubolekisa, izimakethe ezihlukaniselwe amazwe kanye nezinhlelo zokuqagela.
  • Amathokheni angafungi (NFT): Ukudala izinkontileka ezisekela izimpahla zedijithali njengobuciko, imidlalo, noma izikhumbuzo zezemidlalo.
  • Ukuphatha ukuhlinzeka: Ukugadwa kanye ne-automation yezinqubo ze-logistics.
  • Amasistimu okuvota: Ukuqaliswa kwezinqubo zokuvota ezisobala nezivikelekile kusetshenziswa i-blockchain.

Izinzuzo kanye nebubi beSolidity

Esinye sezizathu zokukhuphuka kweSolidity yikhono layo lokuphendula izidingo ze-Ethereum blockchain. Kodwa-ke, njenganoma yibuphi ubuchwepheshe, inobuhle nebubi bayo.

Izinzuzo

  • Ukuvumelana nezimo: Ivumela ukudalwa kwezinhlobonhlobo zezinkontileka ezihlakaniphile.
  • Ezokuphepha: Kufaka phakathi izilawuli zokufinyelela kanye nokuphatha okuhlukile.
  • Umphakathi omkhulu: Inezinsiza eziningi kanye nesizinda sonjiniyela esikhula njalo.

nebubi

  • Ijika lokufunda: Kungaba inselele kulabo abangenawo i-blockchain noma isipiliyoni sokuhlela.
  • Imikhawulo yensiza: Konke ukusebenza ku-blockchain kudla i-GAS, okwandisa izindleko.
  • Ukungaguquki: Inkontileka esetshenzisiwe ayikwazi ukuguqulwa, edinga ukunakekelwa okukhulu phakathi nokudalwa kwayo.

Ukuqalisa ngokuhlela izinkontileka ezihlakaniphile

Uma ufuna ukuqalisa ku-Solidity, isiqalo esihle ukusebenzisa amathuluzi afana Remix, indawo yokuthuthukisa esekelwe kusiphequluli ekuvumela ukuthi ubhale futhi usebenzise izinkontileka ngaphandle kokulungiselelwa okuyinkimbinkimbi. Landela lezi zinyathelo eziyisisekelo:

  1. Ukufinyelela ku- Remix.
  2. Dala ifayela elisha ngesandiso .sol.
  3. Icacisa ilayisense ye-SPDX nenguqulo ye-compiler.
  4. Chaza isivumelwano ngegama contract, futhi ihlela ukucabanga kwayo kwangaphakathi.
  5. Hlola futhi usebenzise inkontileka usebenzisa amathuluzi we-Remix.

Ngalezi zinyathelo, ungaqala ukuzijwayeza nge-syntax ye-Solidity kanye nengqondo ngokusebenzisa izibonelo ezisebenzayo. Ukubaluleka kweSolidity akukhona nje kuphela ekhonweni layo lokudala izinkontileka ezihlakaniphile, kodwa ekuguqulweni okukuvumelayo ngaphakathi kwemikhakha efana nezezimali, ezokuthutha, ukuvota, nokunye. Ukuyifunda kumelela ukutshalwa kwezimali okubalulekile esikhathini esizayo sokuthuthukiswa kwe-blockchain, ukuyibeka njengethuluzi elibalulekile lanoma yimuphi umhleli ofuna ukungena ezweni elihlukaniswe.
