3.0.2

Upgrade Background

REI Network dev team has been hard at work in making sure the success and as per the latest network status, the team is recommending that the Hard Fork be rescheduled to include an improved user experience. Therefore, we canceled hardfork in the version 3.0.1 upgrade. Version 3.0.2 defined a new rei-dao hardfork block height of 15774234 and estimated hardfork time is 9:00:00 UTC on October 11th.

NOTE: The specific time is based on block height.

Version

REI DAO

Upgrade Guide

It's a hard fork version upgrade. All nodes need to complete the upgrade before the block height of 15774234 (approximately 2023-10-11 09:00:00 UTC), otherwise the nodes cannot continue to synchronize after the hard fork. Please refer to the upgrade guide for details.

Version Features

Consistent with 3.0.1
If you have upgraded to 3.0.1, you only need to update the node program, ensure that the startup command remains unchanged, and restart the node.

3.0.1

Upgrade Background

As a new EVM-compatible public chain, REI Network has made continuous progress in self-iteration and performance exploration. After REI Network introduced the "Better POS" module on November 30, 2022, REI Network will usher in another major upgrade. In this upgrade, we have introduced the bls signature and the on-chain parameter management module. We call this upgrade REI DAO Hard Fork.

Version

REI DAO

Upgrade Guide

It's a hard fork version upgrade. All nodes need to complete the upgrade before the block height of 15084585 (approximately 2023-9-11 02:00:00 UTC), otherwise the nodes cannot continue to synchronize after the hard fork. Please refer to the upgrade guide for details.

Version Features

This hard fork includes:

• Introduce the bls signature. After the validator registers the bls public key, it uses the bls signature algorithm to sign the block, and each validator aggregates the signatures, which reduces the size of the block, and improves the block production efficiency and validator security.

  NOTE: You can find the documentation for generating and registering bls here

  In the previous startup commands, the validator needs to unlock the private key, for example

   rei --datadir ~/reiDataDir --mine --coinbase 0xFF96A3BfF24DA3d686FeA7BD4bEB5ccFD7868DdE --unlock 0xFF96...DdE --password ~/password

  After updating the program, the validator needs to add the bls unlock command, for example

   rei --datadir ~/reiDataDir --mine --coinbase 0xFF96A3BfF24DA3d686FeA7BD4bEB5ccFD7868DdE --unlock 0xFF96...DdE --password ~/password --bls-password ~/blspassword --bls-file UTC--2023-03-03T00-05-58.026Z--0xaa257914ddc6207fb4706e6fb2116e61d7b2cfdcab0a81a55ff7b16f7fe05bb8751de51c0fe272084f8a3a47dcfa6170.json

  You need to add two parameters: --bls-password and --bls-file, --bls-password to unlock the bls keystore, --bls-file is the corresponding file path of bls keystore.

  NOTE: After the block 15084585, the validator can remove --unlock and --password parameters, no need to unlock the account private key when the validator starts.

  NOTE: You can find the how to to verify that bls started correctly here

• The logic of validator election is optimized, which improves the efficiency of block production.

• Change some of the on-chain parameters to be controllable by the contract, such as: block rewards, number of validators, etc., to facilitate better-decentralized governance.

• Modified the slash logic for double-signature: after the hard fork, the double-signature validator will be frozen to wait for the ruling from the DAO. In this upgrade, the double-signature penalty amount before the fork will be returned to the DAO address after the hard fork to wait for the ruling.

Upgrade Background

As a new EVM-compatible public chain, REI Network has made continuous progress in self-iteration and performance exploration. After REI Network introduced the "Free Stake" module on July 13, 2022, REI Network will usher in another major upgrade. The new version will make great progress in terms of EVM performance improvement and mechanism innovation. We call this hard fork upgrade - "Better POS".

Version

Better POS

Upgrade Guide

It's a hard fork version upgrade. All nodes need to complete the upgrade before the block height of 9629061 (approximately 2022-12-30 10:00:00 UTC), otherwise the nodes cannot continue to synchronize after the hard fork. Please refer to the upgrade guide for details.

Version Features

This hard fork includes:

• Introduces the Jail Mechanism, and Validators who miss blocks ≥ 300 in one day will be prohibited from producing blocks. Solving the problems of block loss and other validator performance instability;
• evmone binding, which raises the execution efficiency of REI Network EVM by about 5 times;
  Adopts the compression coding algorithm to save the storage space of the system contract;
• Introduces support for snapshot synchronization;
• Lowers the Protection Mode Threshold of REI Network from 10%(100M) to 7%(70M);
