• 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

• Fixed bug in richlist

Weekly Dev Snapshot 📸 👇

• Finished implementation of go-zond-wallet-encryptor-keystore
• Implementation of Dilithium Execution Changes file is in progress, it will generate the file with credentials, allowing one to withdraw the locked balance with staking reward for the validator that has exited.
• Implementation of tools and other required changes for the validator exit is in progress.

QRL Monthly: feat QRL Documentation Revision - August 2023

The QRL documentation is currently being revised with the aim of enhancing user engagement and facilitating development. QRL Zond continues to advance with go-zond-types, wallet-types, staking-deposit-cli, and wallet-encryptor-keystore. Finally, the third episode of “History of Cryptography: Behind The Code” discusses Enigma and Alan Turing.

Read more in our blog.

Weekly Dev Snapshot 📸 👇

• Implemented go-zond-types which is a library that has cryptography related data types supported by Zond.
• Implemented go-zond-wallet-types which is a library that has datatypes related to Zond based wallet and using the go-zond-types library for the cryptography related datatypes.
• Implementation of go-zond-wallet-encryptor-keystore is in progress using the go-zond-wallet-types. This will be used to encrypt and decrypt the keystore files generated by staking-deposit-cli. This library will be used by the beacon node while importing validator wallet from the key store files for the purpose of staking.

Weekly Dev Snapshot

• Implemented staking-deposit-cli which generates multiple dilithium wallet for staking based on the parameters provided along with the keystore files with the dilithium seed encrypted with AES-128-CTR. It also generates files including details such as withdrawal credentials that would be used to create transaction that will be broadcasted further to start staking.
• Bug fixes for staking-deposit-cli
• staking-deposit-cli is currently being tested along with the beacon chain

Weekly Dev Snapshot 📸 👇

• Fixed issue related to P2P syncing
• Fixed genesis block serialization issue
• Go based staking-deposit-cli which will allow to generate staking keys is in progress

QRL Zond

• Added code to support account with smart contract code while generating genesis state from genesis.json, this will be used to deploy deposit contract for staking in genesis block
• Resolved memory related issue with the beacon chain causing beacon node to crash
• Bug fix for the state resumption after node is restarted
• Tested staking 3000+ blocks
• P2P testing & bug fixing is in progress

QRL

• multiple long-standing explorer bugs fixed

Weekly Dev Snapshot

QRL Node v4.0.3

New version is released which fixes a bug with a wallet daemon throwing error while converting non utf-8 data to string will now try to convert the data into hex string

To update, visit our node update guide.

Note: Only required to update if you’re calling the get_block function from the wallet daemon

QRL: New Richlist

• Implementation of richlist-api middleware between indexer and user-facing applications including export of data as CSV for all non-zero balance addresses
