Changes here are more significant because of some good old tech debt in
block production which has grown quite hairy - the reduction in
exception handling at least provides some steps in the right direction.
* Avoid global in p2p macro (fixes#4578)
* copy p2p macro to this repo and start de-crufting it
* make protocol registration dynamic, removing light client hacks et al
* split out light client protocol into its own file
* cleanups
* Option -> Opt
* remove more cruft
* further split beacon_sync
this allows the light client to respond to peer metadata messages
without exposing the block sync protocol
* better protocol init
* "constant" protocol index
* avoid casts
* copyright
* move some discovery code to discovery
* avoid extraneous data copy when sending chunks
* remove redundant forkdigest field
* document how to connect to a specific peer
With Capella, `bls_to_execution_change` SSE should be emitted on the
event stream whenever a new `SignedBLSToExecutionChange` is received.
Add this missing functionality for compatibility with beacon-API specs.
- https://github.com/ethereum/beacon-APIs/pull/248
This requires all object types to be explicitly white-listed for
default serialization. The PR makes the minimal changes, although
a number of similar mechanisms in eth2_rest_serialization can now
be removed.
* Initial commit.
* Fix issues and tests.
* Fix test compilation issue.
* Update AllTests.
* Change the most poor score name from <lowest> to <bad>.
Split sync committee message score in range, so lexicographic scores will not intersect with normal one.
Lexicographic scores should be below to normal scores.
* Address review comments.
Fix aggregated attestation scoring to use MAX_VALIDATORS_PER_COMMITTEE.
Fix sync committee contributions to use SYNC_SUBCOMMITTEE_SIZE.
Add getUniqueVotes test vectors.
* Post-rebase fixes.
* Address review comments.
* Return back score calculation based on actual bits length.
* AllTests modification.
* Add slashing database pruning to VC.
Fix GetBlockHeaderResponse object declaration (spec has been changed).
* Switch to getFinalizedBlockHeader instead.
* Fix proper sign.
Add statements.
Show pruning log statement only when pruning happens.
* Optimize and remove debugging helpers.
Directly initialize `ForkedLightClientObj` instead of separately first
setting the `kind` (initializing everything to zero) and then assigning
the forky data after that.
For symmetry with `forkyState` when using `withState`, and to avoid
problems with shadowing of `blck` when using `withBlck` in `template`,
also rename the injected `blck` to `forkyBlck`.
- https://github.com/nim-lang/Nim/issues/22698
To allow testing https://github.com/ethereum/consensus-specs/issues/3466
add support for selecting fork choice version at launch. This means we
can deploy a different logic when `DENEB_FORK_EPOCH != FAR_FUTURE_EPOCH`
that won't be used on Mainnet.
This PR renames the existing `validator_duties` to `beacon_validators`
and in doing so, names validators running inside the beacon node process
"beacon validators" while those running the VC can be referred to as
"client validators" to disambiguate the two.
The existing `validator_duties` instead takes on a new responsibility:
as a home for logic shared between beacon and client validators - ie
code that provides consistency in implementation and behavior between
the two modes of operation.
Not only does this simplify reasoning about where to put code -it also
reduces the number of dependencies the validator client has from ~5000
to ~3000 modules (!) according to `nim genDepend` significantly reducing
compile times.
- Remove unnecessary `Defect` references
- Remove spurious `SerializationError` references
- Remove duplicate `writeValue` template in `keystore.nim`;
same implementation already exists a bit further above in same file.
* Add support for POST /eth/v2/beacon/blocks
* More descriptive errors
* Address review feedback
* Return 500 (not 400) for a missing implementation case
* Make VC able to understand any type of `/eth/v1/config/spec` response without any changes in source code.
Update compatibility checking.
Now VC is able to obtain any constant from `spec` call.
* Remove RestSpecVC declaration.
* Initial commit.
* Add algorithm in comment.
Remove delays.
Fix logging statement issues.
Change update from epoch to slot.
* Obtain timestamp earlier.
* Add processing delays into algorithm.
* Fix time offset logging to produce integers instead of strings.
* Address review comments.
* Fix copyright year.
Fix updateStatus().
* Remove fields from Slot start log statement.
Fix issues when BN do not support Nimbus Extensions.
Rename metric name and type change.
* Add beacon role to disable time offset check manually.
`nim-serialization` is tagged with `{.raises:[SerializationError].}` so
it is no longer sufficient to catch `SszError` in some situations.
`SszError` inherits from `SerializationError`, so broadening the caught
exception types can be done now, to enable bumping `nim-serialization`.
https://github.com/status-im/nimbus-eth2/pull/5043#issuecomment-1584227993#5061 is also needed to bump `nim-serialization`.
* Refactor api.nim to provide more informative failure reasons.
Distinct between unexpected data and unexpected code.
Deprecate Option[T] usage.
* Fix 400 for produceBlindedBlock().
Get proper string conversion for strategy.
* Fix SSZ encoded versions of ProduceBlockResponseV2, ProduceBlockResponseV2 can be received and decoded.
Fix done() warnings.
Bump presto.
* Fix compilation error with new presto.
Use TcpNoDelay option for Web3Signer.
* Fix produceBlockV2() should provide SSZ responses too.
* Address block encoding issue.
* Fix signing test.
* Bump presto.
* Address review comments.
Use separate functions per format when parsing LC data from REST.
This allows to process events from the eventstream more directly,
as they are always JSON not SSZ. And also makes the code cleaner.
* Initial commit with both methods enabled: `poll` and `event`.
* Address review comments.
* Address review comments.
Fix copyright years.
* After bump fixes.
* fix SSZ response for `produceBlindedBlock`
In `produceBlindedBlock`, we sent the `ForkedBlindedBeaconBlock` when
requested to reply in SSZ format. However, expected result is just the
inner `ForkyBlindedBeaconBlock` together with `eth-consensus-version`.
Note: We do not use SSZ format in our VC for this endpoint at this time,
which explains why we haven't noticed earlier.
* fix Altair/Phase0
The `SAFE_SLOTS_TO_UPDATE_JUSTIFIED` constant is no longer used as the
bouncing attack fix was removed:
https://github.com/ethereum/consensus-specs/pull/3290
Note: Some test networks still define the constant, ignoring the config
constant for now until it is no longer used.
Add compatibility with https://github.com/ethereum/beacon-APIs/pull/290
to the beacon node. Behaviour when configured with multiple ELs is not
specified; intention suggests to indicate whether all ELs are offline.
* allow trusted node sync based on LC trusted block root
Extends `trustedNodeSync` with a new `--trusted-block-root` option that
allows initializing a light client. No `--state-id` must be provided.
The beacon node will then use this light client to obtain the latest
finalized state from the remote server in a trust-minimized fashion.
Note that the provided `--trusted-block-root` should be somewhat recent,
and that security precautions such as comparing the state root against
block explorers is still recommended.
* fix
* workaround for `valueOr` limitations
* reduce magic numbers
* digest len > context len for readability
* move `cstring` conversion to caller
* avoid abbreviations
* `return` codestyle
Two fixes to `/eth/v1/debug/fork_choice`:
- `validity` enum is expected to be serialized as string instead of int
- `data` wrapper is not expected for this endpoint
* Refactor nimbus_signing_node to support Unix signals.
* Fix SN unable to close REST server properly.
* Fix `keys`, `deposit` and `validator_registration` endpoints issues.
Add getValidatorExitSignature() and getDepositMessageSignature() to validator_pool.
* Add /reload endpoint and implementation.
Fix signData to not cancel `timer`.
Fix validator_pool should clear attachedValidators table.
* Diva protocol enhancement implementation.
* Fix issue when VC unable to detect errors properly and act accordingly.
Switch all API functions used by VC to RestPlainResponse, this allows us to print errors returned by BN servers.
* Fix issue when prepareBeaconCommitteeSubnet() do not perform actions when BN is optimistically synced only.
* Fix Defect issue.
* Fix submit/publish returning `false` when operation was successful.
* Address review comments.
* Fix some client calls unable to receive `execution_optimistic` field, mark BN as OptSynced when such request has been made.
* Adjust warning levels.
