stars-labs/heco-chain v1.2.0

on GitHub

This release contains go-ethereum's code follow up AND HECO chain-governance improvement.

And this release will support three hard-forks, all of these hard-forks share the same hard-fork block number, which is:

• 8290000 for the Testnet (Estimated Target Date: Thu Sep 16 2021 10:52:06 GMT+0800)
• 8577000 for the Mainnet (Estimated Target Date: Sun Sep 26 2021 10:54:45 GMT+0800)

All nodes should be upgraded before the hard-forks take effect.

Sophon Hard Fork

• upgrade some system contracts, supportting the new mechanism of block-rewards distribution (see the London hard-fork for detail).

Berlin Hard Fork

It's the same as the go-ethereum.

London Hard Fork

• Modify the distribution of block rewards: (a) block rewards are divided into three parts: burn, foundation rewards and validator rewards.The rates can be adjusted through the system contract. (b) the amount of gas to be burned is controled by the burnRate in the system-validators contract, burned = blockRewards * burnRate/10000, and the burnRate can be changed by the HECO DAO; (c) the burned HT will be sent to 0x000000000000000000000000000000000000FaaA.
• The BaseFee will always be zero.

Other features:

Mostly the same as go-ethereum v1.10.8, except that

• the TxLookupLimit is 0 by default (which means keep all transactions index by default).
• now it will be ok to debug_trace those blocks containing sys-txs (transactions initiated inside the Congress engine).
