QRL Zond Development

Several changes and improvements have been made to the execution node and related packages. One notable change is the unification of the pqaccounts and account packages into a single account package. Additionally, the pqcrypto package has undergone fixes and updates, including changes to the sign function.

The update also introduces a constant named DilithiumSignatureLength and makes various changes to transaction data and API to support Dilithium-based wallets. This includes added and initializing DilithiumWithdrawalPrefixByte, ZondAddressWithdrawalPrefixByte & DomainDilithiumToExecutionChange in config, fields which are used in the staking-deposit-cli for staking deposits and withdrawal.

This includes updates to the RPCTransaction API with new fields for PublicKey and Signature. Transaction marshalling has been updated to accommodate these new fields for Dilithium compatibility.

Several bug fixes and unit test updates have been implemented, and successful testing has been conducted for making and signing transactions from the CLI. Transaction Pool in the Execution Node has also been tested successfully, including fund transfers between Dilithium wallets.

The update covers progress in validator staking, including the exit of validators and withdrawal of balances. Non-required flags have been removed from the staking-deposit-cli, and various bug fixes and improvements have been made.
