v22.7.0 Released

[antonydenyer]

🎉 Enhancements 🎉

Support Empty Blocks in QBFT

You can configure your QBFT network to not produce blocks when you have no transactions, saving on disk space. Documentation available https://consensys.net/docs/goquorum/en/latest/configure-and-manage/configure/consensus-protocols/qbft/#configure-empty-block-period

• qbft: add new block period setting used when the block is empty qbft: add new block period setting used when the block is empty #1433

Re-enable gas

GoQuorum now supports gas - this is so you can make your networks public facing whilst mitigating the risk of a denial of service attack. Documentation available https://consensys.net/docs/goquorum/en/latest/concepts/gas-enabled-network/

• Enable gas price Enable gas price #1446
• configurable gas limit configurable gas limit #1448

Transitions

Further enhancements have been made to transitions config to make it easier to manage and change your network over time. You can now manipulate the following configurations at any block height using transitions:

• algorithm ( qbft/ibft )
• epochLength ( Number of blocks that should pass before pending validator votes are reset )
• blockPeriodSeconds ( Minimum time between two consecutive IBFT or QBFT blocks’ timestamps )
• emptyBlockPeriodSeconds ( Minimum time between two consecutive IBFT or QBFT a block and empty block’ timestamps )
• requestTimeoutSeconds ( Minimum request timeout for each IBFT or QBFT round )
• contractSizeLimit ( Maximum smart contract code size in kb)
• validatorContractAddress ( Smart contract address for list of validators )
• validatorSelectionMode ( Validator selection mode to switch )
• enhancedPermissioningEnabled ( aka QIP714Block )
• privacyEnhancementsEnabled ( privacy enhancements (mandatory party, private state validation) )
• PrivacyPrecompileEnabled ( enable marker transactions support )
• gasPriceEnabled ( enable gas price )
• miner.gasLimit ( Miner gas ceiling limit for each block)
• twoFPlusOneEnabled ( Ceil(2N/3) is the default you need to explicitly use 2F + 1 if migrating from an old network )
• transactionSizeLimit ( change the ceiling size of a transaction )

Note that you can enable and disable features, where as with previous release you could only enable a feature at a block height.
