The warning gives too many false positives - until things work properly,
locally one can just remove it to find instances where it gets used..

For EIP-7702 SetCode transaction, it is necessary to identify the
authority issuing an authorization. Its account's code is set to
proxy to the authorization address if successful.
Transaction signing is something that happens in a lot of places - this
PR introduces primitives for transaction signing in `transaction_utils`
such that we can use the same logic across web3/eth1/etc for this simple
operation.
`transaction_utils` also contains a few more "spec-derived" helpers for
working with transactions, such as the computation of a contract address
etc that cannot easily be introduced in `transactions` itself without
bringing in dependencies like secp and rlp, so they end up in a separate
module.
Finally, since these modules collect "versions" of these transaction
types across different eips, some tests are moved to follow the same
structure.
serialize fewer non-eth types and more eth types - this module is
fraught with issues however since there's no one good "canonical"
encoding to choose - this goes back to the json ser framework lacking
good isolation between projects.
Since these types were written, we've gained an executable spec:
https://github.com/ethereum/execution-specs
This PR aligns some of the types we use with this spec to simplify
comparisons and cross-referencing.
Using a `distinct` type is a tradeoff between nim ergonomics, type
safety and the ability to work around nim quirks and stdlib weaknesses.
In particular, it allows us to overload common functions such as `hash`
with correct and performant versions as well as maintain control over
string conversions etc at the cost of a little bit of ceremony when
instantiating them.
Apart from distinct byte types, `Hash32`, is introduced in lieu of the
existing `Hash256`, again aligning this commonly used type with the spec
which picks bytes rather than bits in the name.
We don't need to clear keccak context after hashing ethereum data since
it is already public - similar to
https://github.com/status-im/nimbus-eth2/pull/222.
Because we overwrite the result fully, we also don't need to zero first.
EIP-4844 blob sidecars are a concept that only exists in the mempool.
After inclusion of a transaction into an execution block, only the
versioned hash within the transaction remains. To improve type safety,
replace the `Transaction.networkPayload` member with a wrapper type
`PooledTransaction` that is used in contexts where blob sidecars exist.
1. Fix Assertion error when receipt is not a List nor has a single
byte value. Receiving such garbage data would cause a crash.
2. Fix decoding of Receipt list by adding the missing Blob
encapsulation
Also added tests for these scenarios.
Instead of patching BlockHeader or BlockBody codec
each time it get additional optional fields,
this PR make the rlp codec automatically handle
optional fields. Thus rlp codec overloading of
EthBlock, BlockHeader, and BlockBody can be removed.
Using exception in rlp.append turn out creates more problem than it solve.
`blockHash` operation is literally everywhere in nimbus-eth1, nimbus-eth2, and fluffy-code.
The compiler begins to complain about unlisted exception.
Rlp bytes coming from network and test vectors already verified by the decoder.
So, any invalid optional fields of blockheader that come into rlp.append means
programming error. Assertion will be more apropiate in this situation and less problematic.
including:
- fix rlp.append of BlockHeader
- add tests for rlp.readRecordType of BlockBody
- add tests for rlp.append of BlockHeader
- add tests for EthBlock roundtrip
