* Initial implementation of era1 + export + verify
Initial implementation of era1 + export and verify command in the
existing eth_data_exporter.
* Quick verify version to test with geth created era1 files
* Add Era1File object and getter for specific block tuple
* Add getAccumulatorRoot and update AccumulatorRoot type name
+ clean-up of some comments.
* Implement BlockIndex based verify + additional helper calls
+ fix bug for reading last (incomplete) Era1 file
* Fix init BlockIndex offsets for last era + extra check on reading
* Remove duplicated e2store code
* Correct the shortcut for ommershash verification post Shanghai
There was a faulty length check being done in the assumption that
the uncles field was already the list. However it is still the
RLP encoded data at that point, hence we check directly for the
RLP encoded value for empty list.
* Fix copy-paste error in withdrawal root verification
And print out the hashes in txs root and withdrawal root
verification
* Nimbus folder environment update
details:
* Integrated `CoreDbRef` for the sources in the `nimbus` sub-folder.
* The `nimbus` program does not compile yet as it needs the updates
in the parallel `stateless` sub-folder.
* Stateless environment update
details:
* Integrated `CoreDbRef` for the sources in the `stateless` sub-folder.
* The `nimbus` program compiles now.
* Premix environment update
details:
* Integrated `CoreDbRef` for the sources in the `premix` sub-folder.
* Fluffy environment update
details:
* Integrated `CoreDbRef` for the sources in the `fluffy` sub-folder.
* Tools environment update
details:
* Integrated `CoreDbRef` for the sources in the `tools` sub-folder.
* Nodocker environment update
details:
* Integrated `CoreDbRef` for the sources in the
`hive_integration/nodocker` sub-folder.
* Tests environment update
details:
* Integrated `CoreDbRef` for the sources in the `tests` sub-folder.
* The unit tests compile and run cleanly now.
* Generalise `CoreDbRef` to any `select_backend` supported database
why:
Generalisation was just missed due to overcoming some compiler oddity
which was tied to rocksdb for testing.
* Suppress compiler warning for `newChainDB()`
why:
Warning was added to this function which must be wrapped so that
any `CatchableError` is re-raised as `Defect`.
* Split off persistent `CoreDbRef` constructor into separate file
why:
This allows to compile a memory only database version without linking
the backend library.
* Use memory `CoreDbRef` database by default
detail:
Persistent DB constructor needs to import `db/core_db/persistent
why:
Most tests use memory DB anyway. This avoids linking `-lrocksdb` or
any other backend by default.
* fix `toLegacyBackend()` availability check
why:
got garbled after memory/persistent split.
* Clarify raw access to MPT for snap sync handler
why:
Logically, `kvt` is not the raw access for the hexary trie (although
this holds for the legacy database)
- Remove failing on withdrawalsRoot to allow Shanghai BlockHeader.
Still need to add real checks in block header / body validation.
- Add withdrawals array to Block object for JSON-RPC API
Allow for the Fluffy Portal bridge to inject receipts. This
requires a web3 endpoint to be provided, and currently only
Alchemy is supported due to the used JSON-RPC endpoint.
* Refactoring in preparation for time-based forking.
* Timestamp-based hard-fork-transition.
* Workaround SideEffect issue / compiler bug for both failing locations in Portal history code

* Reduce Nim 1.6 compiler warnings/hints for Fluffy and Nimbus proxy
Mostly raises Defect removals, TaintedString removal and some
unnecessary imports.
Also updating the copyright years alongside.
* Further reduce Nim 1.6 compiler warnings/hints for Nimbus
* Move BlockHeaderWithProof content to content key selector 0
- Remove as content type with content key selector 4
- Replace regular block header with BlockHeaderWithProof at
content key selector 0
* Apply blockHeader content key also to bridge
* Add tests for header with proof generation and verification
This is an example of how the beacon state historical_roots could
be added with a proof to be able to provide on the network and
verify by means of proof against the state root.
The `BlockHeader` structure in `nim-eth` was updated with support for
EIP-4844 (danksharding). To enable the `nim-eth` bump, the ingress of
`BlockHeader` structures has been hardened to reject headers that have
the new `excessDataGas` field until proper EIP4844 support exists.

- Switch from using Option to Opt which allows for smoother
usage with already existing Result types
- With all moved to Opt, make more use of valueOr to avoid
too many if else clause indentation and unstead have a more
clear error path at each step
- Remove dead code, char limits, style guide, etc.
- Replace getEncodedKeyForContent with ContentKey.init
and use ContentKey.init for each type
The `BlockHeader` structure in `nim-eth` was updated with support for
EIP-4895 (withdrawals). To enable the `nim-eth` bump, the ingress of
`BlockHeader` structures has been hardened to reject headers that have
the new `withdrawalsRoot` field until proper withdrawals support exists.

* Add headers with proof content type and use it for verification
- Add BlockHeaderWithProof content type & content
- Use BlockHeaderWithProof content to verify if chain data is
part of the canonical chain
- Adjust parser & seeder code to be able to seed these headers
with proof
- Adjust eth_data_exporter to be able to export custom header
ranges for which to build proofs (mostly for testing)
There is currently quite some ugliness & clean-up needed for which
a big part is due tos upporting both BlockHeader and
BlockHeaderWithProof on the network.
* Change accumulator proof to array / SSZ vector type
- Change accumulator proof to SSZ vector instead of SSZ list.
- Add and use general buildProof and buildHeaderWithProof func.
* Make the BlockHeaderWithProof an SSZ Union with None option
* Update portal-spec-tests to master commit
- Can write epoch accumulators to files now with eth_data_exporter
- RPC requests to gossip epoch accumulators now uses these files
instead of building on the fly
- Other build accumulator calls are adjusted and only used for
tests and thus moved to testing folder
For accumulator building we now use intermediary header epoch
files which renders the use of a temporary db for this no longer
needed. Code was already no longer in use.
Portal master accumulator was removed from the network specs as a
content type shared on the network, as since the merge this is
a finite accumulator (pre-merge only).
So in this PR the accumulator gets removed as network type and
gets instead baked into the library. Building it is done by
seperate tooling (eth_data_exporter).
Because of this a lot of extra code can be removed that was
located in history_network, content_db, portal_protocol, etc.
Also removed to option to build the accumulator at start-up
of fluffy as this takes several minutes making it not viable.
It can still be loaded from a provided file however.
The ssz accumulator file is for now stored in the recently
created portal-spec-tests repository.
- Let accumulator finish its last pre merge epoch (hash_tree_root
on incomplete epoch).
- Adjust code to use isPreMerge and remove isCurrentEpoch
- Split up tests to a set that runs with a mainnet merge block
number and a set that runs with a testing value.
Also requires us to split header data propagation from block body
and receipts propagation as the now fixed bug would allow for more
data to be gossiped even when data does not get validated (which
requires the headers).
* Fix bug in inCurrentEpoch and improve accumulator related tests
- Fix negative wraparound / underflow in inCurrentEpoch
- Add tests in accumulator tests to verify the above
- Add header offer tests with accumulator that does and doesn't
contain historical epochs
- Additional clean-up of history tests
- enable canonicalVerify in the tests
