QRL Weekly, 2023-September-12

Weekly Dev Snapshot 📸 👇

• Implemented CLI functionality to generate Dilithium to execution change
• Changed default value of execution-address flag in staking-deposit-cli while generating new seed for staking deposit
• Added and initialized DilithiumWithdrawalPrefixByte, ZondAddressWithdrawalPrefixByte & DomainDilithiumToExecutionChange in config, these fields are used in staking-deposit-cli for stakings deposits and withdrawal.
• WithdrawalCredentialsHash function now uses DilithiumWithdrawalPrefixByte to compute hash while generating new staking deposit
• Added validation of withdrawal credentials in validateDeposit function in staking-deposit-cli
• Added proto messages for Dilithium based execution change for validator exit
• Added other helper functions such as DecodeHex, ToSizedDilithiumSignature, ToSizedDilithiumPublicKey for staking-deposit-cli
• Node has been successfully tested for 14000-15000 blocks and intentionally stopped thereafter.
• Fixed bug in richlist
