Galileo伽利略(v1.1.2)

The Galileo (v1.1.2) release is a hotfix for an online issue #1880 that could cause verifier nodes to be slashed.

Bug-fixes

• Fix data inconsistency in concurrent cases due to the use of global random instancePlatON-issue-1880

Notes

When the seed of a random instance is contaminated by concurrency, there will be a 'BAD BLOCK' in the nodes' log. Besides, the block will not be verified, resulting in failure to receive enough votes for the proposer's block. There are 3 possible situations as follows,

• If the first block produced by the node is not affected, but the seed has been contaminated in subsequent blocks. The node's block production rate will be affected because the final confirmed block is less than 10, the expected number.

• According to Giskard consensus mechanism, if the first block is contaminated by concurrency, the next blocks can be proposed without confirmation. Subsequently, all blocks of the node in this round will not be confirmed, which will eventually result in 0 blocks proposed and the nodes being slashed.

• For non-block-producing nodes, the seed may be contaminated while verifying the block, resulting in failure to pass the block verification. Hence, the overall fault tolerance of the consensus will be reduced regarding that the contaminated node can't vote.

  In the above consideration, it is strongly recommended that all verifiers upgrade your node immediately.

Copernicus哥白尼(v1.1.1)

The Copernicus (v1.1.1) release is a patch release of the core development team's maintenance, which includes the implementation of the EVM compatibility proposal PIP-2 as well as fixes for some known issues.

Improvements

• EVM compatibility proposal PIP-2 solution implementation
• Synchronised update of features in Ethereum1.9.0 release
• Synchronized incorporation of ethereum vulnerability CVE-2021-39137, detailed description available here

Bug-fixes

• Fix bug that staking nodes cann't produce blocks #1836
• Fix web3js not updating bindata issue
• Fix pre-estimated gas interface error #1819
• Fix FastSyncStatus exception after abnormal termination #1775
• Fix platon_getlogs did not work
• Fix the dockerfile build failure issue #1537
• Fix the problem that listening to events with the subscription interface gives 2 identical logs #1867
• Fix the problem that platon_estimateGas returns too few messages #1819

Notes

1. This release contains some features of ethereum 1.9.0, including the feature on freezer, see ethereum-19244 for details
2. According to the actual tesging, the storage overhead of PlatON mainnet nodes will be partially increased after upgrading to 1.1.1 (for example, the storage space will be increased by about 8G after upgrading from 16,200,000 block high)
3. Because of the freezer feature of migrating the original data, the process will migrate some of the historical data to the freezer database for a period of time after the node is upgraded, and during this process (about 1 hour or so)
   a. CPU overhead will increase compared to normal operation, about 2~4 times the load in normal state, after the data migration is completed it will return to normal
   b. A few nodes will experience a short increase in memory overhead after the upgrade and reboot, which will return to normal after the data migration is completed.
   Please pay attention to the resource usage of the host, it is recommended to use swap partition, if possible, you can also choose to upgrade the physical memory of the machine to 16GB
4. The migrated data is not applicable to the old version (1.1.0), it is recommended to back up the data (data/platon directory) before upgrading
5. This version does not require an on-chain governance upgrade, but it is recommended that nodes upgrade as soon as possible due to the fixing of critical vulnerabilities

v1.1.0

PlatON version 1.1.0 is a feature release that implements long-discussed optimisation features in PIP-3.

Optimizations

• Optimize transaction dissemination strategy, send transaction hash value to nodes that do not directly broadcast transactions issue-1780
• Support the feature of RPC returning chainid (refer to EIP-695)
• Open the getWaitSlashingNodeList interface for obtaining Slashing status issue-1787
• According to the community proposal, take the random election of the PlatON network blocking node. The expected value of the cumulative binomial distribution function is adjusted from 30 to 43. The candidate nodes are shuffled to increase the randomness. For details, please refer toissue-1785，Discuss

Bug fixes

• Fix the failure to restart the node when the fast synchronization is not completed issue-1775
• Fix the bug that gasPrice must be passed in for the estimation of the governance contract when the gas estimate interface is called issue-1758
• Fix the bug that the call method occasionally returns -32000 error code issue-1769
• Fix the bug of BAD BLOCK after the node fast synchronization fails issue-1783
• Fix the bug of the value of platon_caller being incorrect when WASM is called across contracts issue-1779
• Synchronously fix the bug of incorrect return value of Ethereum txpool's batch inserting transaction ETH-21683

v1.0.0

This release is the first major release of PlatON-Go and the initial live-net version of the mainnet, it marks an important milestone for PlatON network.
We have implemented all features described in the PlatON Economic Bluepaper and made some targeted optimizations based on Alaya(including bug fixes):

• Alternative validators qty 201, validators qty 43
• Minimum staking amount 100,000 lat
• Maximum number of consensus rounds tolerated for no-proposing blocks 20
• Slashing: number of locked epochs when no-proposing block 56
• Slashing: no-proposing block will be slashed lats latequivalent to 2500 block rewards
• Number of locked epochs when unstaking 168
• Chain ID 100
• Fixed the bug of dockerfile mismatching #1537
• Fixed OOM issue caused by platon_blockhash function of wasm contract #1622
• Filled in genesis block timestamp and genesis block manifesto
