feat: london #1135

davidmurdoch · 2021-09-07T23:20:10Z

Addition of EIP-1559 transactions.
Added baseFeePerGas to a block
When London is activated, use baseFeePerGas as the block's gasPrice
When London is activated, re-prioritize the txPool based off of the transaction's new effectiveGasPrice
Write tests for miner and txPool reordering
Fix some instamine behavior
- Added a DESIGN-DECISIONS.md to explain the change
Set london as the default hard fork
Fixed bug in how typed transactions are signed (no longer including the tx type)

Curious about the reasoning for this!

We should never mutate the json data a user gives us (like in provider.send("eth_sendTransaction", transaction)) but in one place in our code we were. Marking the type as Readonly prevents that sort of bug from happening.

It doesn't just throw with an "invalid remainder" message now :-)

Probably fine to leave it as is and fix when we re-organize the transactions classes

I think the _common is needed because the super class needs it because LegacyTransaction needs it. The _ makes the linter stop complaining about an unused variable.
