Fixes

Maintenance release

• Go version upgrade to 1.19 #1601

Fixes

🎉 Enhancements 🎉

• perf: improved func ValidateNodeForTxn node id parsing #1578

Critical Fixes

• If communication with tessera fails GoQuorum should retry and then exit #1575

Prior to this change GoQuorum would silently continue if it received a 5xx response from tessera. This could cause a possible divergent state when one should not exist. This would be more prevalent in environments where tessera was not 100% highly available and reliable.

• Update indirect github.com/gogo/protobuf to 1.3.2 #1571
• Fix validator selection mode on qbft config #1570
• Add extra trace logs for tessera #1562

• Fix block period validation when reducing the block period at transition height #1564
• fix: incorrect link of QuickStart #1550

⚠️ Breaking Changes ⚠️

qbft issues with block rewards and mining beneficiary #1547

If you have started running a network with block rewards enabled and specifying a mining beneficiary you must upgrade each node individually and perform a full sync. This change fixes an issue with gas rewards not being allocated to the correct beneficiary.

Fixes

• fix: qbft empty block period waiting too long #1549
• fix: debug.traceCall: check nil transactions #1537

🎉 Enhancements 🎉

QBFT Validator Override

Add support to allow a list of validators to be specified at a block height. This is useful if you loose validator keys and need to reset the list of validators. The ability to propose and vote on validator inclusion will continue at subsequent blocks. #1530

 "transitions": [
        {
          "block":12,
          "validatorSelectionMode":"blockheader",
          "validators":["0xed9d02e382b34818e88b88a309c7fe71e65f419d", "0x..."]
        }
      ]

Validator Rewards

⚠️ This version contains a major bug with block rewards - please use v22.7.3 where it is fixed ⚠️

With the re-introduction of gas fees back into GoQuorum you need to have some gas to be able to spend! The introduction of validator rewards allows a fixed amount of BlockReward to be allocated to someone each block. You could use this to fill up a faucet contract or the network operators wallet for distribution. #1502

 "transitions": [
        {
          "block":12,
          "beneficiaryMode":"fixed",
          "miningBeneficiary":"0xed9d02e382b34818e88b88a309c7fe71e65f419d"
        }
      ]

  (maintenance release, containing bug fixes and performance improvements)

Deprecations

Support for eth/64 has been dropped - 22636
If you wish to upgrade any node on your network to this version you should ensure that all other nodes support eth/65. This was releases in [v21.4.0]

Fixes

• fix: qlight token refreshment #1488
• Bump karalabe/usb dependency to latest release #1482
• github has deprecated ubuntu 18, replace it 18 with 20 #1484

🎉 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 #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 #1446
• 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.
