INIT_CODE_HASH ምንድነው እና በDeFi ስማርት ኮንትራክቶች ውስጥ እንዴት ይሰላል / ጥቅም ላይ ይውላል

የ Init code hash በመሠረቱ የኮንትራቶች ባይትኮድ keccak256 ሃሽ ነው። የ Init Code አጠቃቀም

Init code hash ያስፈልጋል "የአድራሻ ስሌት የ init code ሃሽን ስለሚወስን። Init code የሚፈጽምበት ጊዜ ወደ state የሚገባውን runtime bytecode የሚያመነጭ ኮድ ነው፣ እናም በተለምዶ በከፍተኛ ደረጃ ቋንቋዎች 'constructor' ለመተግበር ያገለግላል።" "EIP-1014: Skinny CREATE2," Ethereum Improvement Proposals, no. 1014, April 2018. [Online serial]. Available: https://eips.ethereum.org/EIPS/eip-1014.

የ Init Code አጠቃቀም የ init code ዋና አጠቃቀም አድራሻዎችን ለማግኘት ነው። CREATE2 እና የኮንትራት init code እንዴት ተጠቅመን ለኮንትራት ማሰማራት የበለጠ ቀልጣፋ አድራሻዎችን 'ማግኘት' እንደምንችል ምሳሌ ለማየት https://github.com/0age/create2crunch ይመልከቱ። የኮድ init hash ለእርስዎ ለማመንጨት forge የሚጠቀም ቀላል የ bash ስክሪፕት እነሆ፡
