Global Priority

Very HIGH: This is a very high priority release, and you must upgrade as as soon as possible.

• runtime version 20 -> 22
• Improve bitcoin gateway
• Update substrate to Polkadot-v0.9.18
• Add evm London support

This runtime introduces many changes to our Ethereum layer, specially around the EIP 1559. Here are the important parts:

EVM 0.33.1 - London support

• EIP-3198: BASEFEE opcode
• EIP-3529: Reduction in refunds
• EIP-3541: Reject new contracts starting with the 0xEF byte

Ethereum 0.11.1

• EIP-2718: Typed transactions
• EIP-2930: Optional access lists
• EIP-1559: Fee market change

Ethereum API - Changes

• new rpc eth_feeHistory: Returns transaction fee data for up to 1,024 blocks.
• new property block.baseFeePerGas: baseFeePerGas used for the given block
• new property transactionReceipt.effectiveGasPrice: gas price being used for the transaction
• new property transaction.accessList: is an array of type [[{20 bytes}, [{32 bytes}...]]...], storing the contract address and the storage keys. Ex:

[
  [
    "0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae",
    [
     "0x0000000000000000000000000000000000000000000000000000000000000003",
     "0x0000000000000000000000000000000000000000000000000000000000000007"
    ]
  ], [
    "0xbb9bc244d798123fde783fcc1c72d3bb8c189413",
    []
  ]
]

• new property transaction.maxFeePerGas: how much BaseFee the transaction is allowed to pay.
• new property transaction.maxPriorityFeePerGas: Correspond to the "tip" to the miner. (Note: It is currently included in the normal fees, being 100% to validators)
• new property transaction.type: The current type of transaction 0 (Legacy), 1 (EIP-2930), 2 (EIP-1559)
• The base fee used in block is currently constant (450Gwei on SherpaX). The call the eth_gasPrice will return that value.

How to sync blocks from genesis(block #0)

• (0) You should know Debug: panicked at 'Storage root must match that calculated ' #609
  if you use ChainX v4.x.x directly sync blocks will be stuck at #881910 or other block.
• (1) Compile ChainX v3.0.0 by nightly-2020-09-30 or Download chainx-v3.0.0-ubuntu20.04-x86_64-unknown-linux-gnu-1
  the ChainX v3.0.0 seed nodes are bad, so you should use new mainnet bootnodes with --bootnodes

"/ip4/52.77.243.26/tcp/23555/ws/p2p/12D3KooWQ6GGfmvmmmsbKRmZqMA3A8rxaHz25HvA7JNBbcZhLXtk"
"/ip4/120.26.57.227/tcp/36789/ws/p2p/12D3KooWEAX2BcQCZP79MuxQpqLQUop7P3tZY97eNxxUgc4ZTu3k"
"/ip4/47.114.74.52/tcp/36789/ws/p2p/12D3KooWJPMUkGytfAMt3AMqm4AFn4VToXjbWZoC4Z2NxXNXvTwb"

• (2) Until #3038400, please use ChainX v3.0.0 to synchronize with NativeElseWasm (default mode)
• (3) For blocks after #3038400, complete (2) first, and then replace ChainX v3.0.0 with ChainX v4.x.x to complete the db migration (note that the migration process is irreversible, it is recommended to back up the data first)
• (4) ChainX v4.x.x continues to synchronize blocks

Rust compiler versions
