Chaincode pib thiab tswj cov ntaub ntawv hauv xeev los ntawm kev xa khoom xa los ntawm daim ntawv thov.

Hauv qhov no, Dab tsi yog Chaincode hauv Blockchain?

Lub hauv paus ntawm ib qho blockchain platform yog daim ntawv teev npe, sib koom, tamper-pov thawj keeb kwm ntawm lub ntiaj teb. Tshwj xeeb, nws yog cov ntaub ntawv ntawm txhua qhov kev hloov pauv hauv nws qhov peev txheej. Chaincode yog lub sij hawm rau cov kev pab cuam uas khiav saum lub blockchain los siv lub lag luam logic ntawm yuav ua li cas cov ntawv thov cuam tshuam nrog daim ntawv teev npe.

Ib yam li ntawd, lub luag haujlwm ntawm Chaincode yog dab tsi? Chaincode yog ib qhov kev pab cuam (smart contract) uas yog sau los nyeem thiab hloov kho cov ntaub ntawv hauv lub xeev. Cov neeg tsim khoom siv chaincode los tsim cov ntawv cog lus ua lag luam, kev txhais cov cuab yeej cuab tam, thiab sib sau ua ke-tswj cov ntawv thov kev ua haujlwm.

Qhov twg Chaincode muaj nuj nqi hu ua thaum Chaincode yog thawj zaug xa tawm?

Init yog hu ua thaum chaincode yog xa mus rau cov ua ntej lub sij hawm, los yog upgraded rau ib tug tshiab version. Qhov no muaj nuj nqi tuaj yeem muaj cov logic uas koj xav siv, lossis nws tuaj yeem tso tseg. Piv txwv ntawm ib qho yooj yim init muaj nuj nqi yog cov hauv qab no: func (t *SmartContract) Init(stub shim. ChaincodeStubInterface) phooj ywg.
