all: implement EIP-1559 (#22837) 
This is the initial implementation of EIP-1559 in packages core/types and core.
Mining, RPC, etc. will be added in subsequent commits.

EIP-1559 testing

This test contains testcases for EIP-1559, which uses an new transaction type and has a new block parameter.

Prestate

The alloc portion contains one contract (0x000000000000000000000000000000000000aaaa), containing the following code: 0x58585454: PC; PC; SLOAD; SLOAD.

Essentialy, this contract does SLOAD(0) and SLOAD(1).

The alloc also contains some funds on 0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b.

Transactions

There are two transactions, each invokes the contract above.

  1. EIP-1559 ACL-transaction, which contains the 0x0 slot for 0xaaaa
  2. Legacy transaction

Execution

Running it yields:

$ dir=./testdata/9 && ./evm t8n --state.fork=London --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --trace && cat trace-* | grep SLOAD
{"pc":2,"op":84,"gas":"0x48c28","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0","0x1"],"returnStack":null,"returnD
ata":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":3,"op":84,"gas":"0x483f4","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x0","0x0"],"returnStack":null,"returnDa
ta":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":2,"op":84,"gas":"0x49cf4","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0","0x1"],"returnStack":null,"returnD
ata":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":3,"op":84,"gas":"0x494c0","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0","0x0"],"returnStack":null,"returnD
ata":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}

We can also get the post-alloc:

$ dir=./testdata/9 && ./evm t8n --state.fork=London --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --output.alloc=stdout
{
 "alloc": {
  "0x000000000000000000000000000000000000aaaa": {
   "code": "0x58585454",
   "balance": "0x3",
   "nonce": "0x1"
  },
  "0x2adc25665018aa1fe0e6bc666dac8fc2697ff9ba": {
   "balance": "0xbfc02677a000"
  },
  "0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b": {
   "balance": "0xff104fcfea7800",
   "nonce": "0x2"
  }
 }
}

If we try to execute it on older rules:

dir=./testdata/9 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --output.alloc=stdout
ERROR(10): Failed signing transactions: ERROR(10): Tx 0: failed to sign tx: transaction type not supported

It fails, due to the evm t8n cannot sign them in with the given signer. We can bypass that, however, by feeding it presigned transactions, located in txs_signed.json.

dir=./testdata/9 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs_signed.json --input.env=$dir/env.json 
INFO [05-07|12:28:42.072] rejected tx                              index=0 hash=b4821e..536819 error="transaction type not supported"
INFO [05-07|12:28:42.072] rejected tx                              index=1 hash=a9c6c6..fa4036 from=0xa94f5374Fce5edBC8E2a8697C15331677e6EbF0B error="nonce too high: address 0xa94f5374Fce5edBC8E2a8697C15331677e6EbF0B, tx: 1 state: 0"
INFO [05-07|12:28:42.073] Wrote file                               file=alloc.json
INFO [05-07|12:28:42.073] Wrote file                               file=result.json

Number 0 is not applicable, and therefore number 1 has wrong nonce, and both are rejected.
