handle duplicate pubkeys in sync committee (#2902) When sync committee message handling was introduced in #2830, the edge case of the same validator being selected multiple times as part of a sync subcommittee was not covered. Not handling that edge case makes sync contributions have a lower-than-expected participation rate as each sync validator is only counted up through once per subcommittee. This patch ensures that this edge case is properly covered.

Validator monitoring (#2925) Validator monitoring based on and mostly compatible with the implementation in Lighthouse - tracks additional logs and metrics for specified validators so as to stay on top on performance. The implementation works more or less the following way: * Validator pubkeys are singled out for monitoring - these can be running on the node or not * For every action that the validator takes, we record steps in the process such as messages being seen on the network or published in the API * When the dust settles at the end of an epoch, we report the information from one epoch before that, which coincides with the balances being updated - this is a tradeoff between being correct (waiting for finalization) and providing relevant information in a timely manner)

move quarantine outside of chaindag (#3124) * move quarantine outside of chaindag The quarantine has been part of the ChainDAG for the longest time, but this design has a few issues: * the function in which blocks are verified and added to the dag becomes reentrant and therefore difficult to reason about - we're currently using a stateful flag to work around it * quarantined blocks bypass the processing queue leading to a processing stampede * the quarantine flow is unsuitable for orphaned attestations - these should also should be quarantined eventually Instead of processing the quarantine inside ChainDAG, this PR moves re-queueing to `block_processor` which already is responsible for dealing with follow-up work when a block is added to the dag This sets the stage for keeping attestations in the quarantine as well. Also: * make `BlockError` `{.pure.}` * avoid use of `ValidationResult` in block clearance (that's for gossip)

singe validator key cache Instead of keeping a validator key list per EpochRef, this PR introduces a single shared validator key list in ChainDAG, and cleans up some other ChainDAG and key-related issues. The PR does not introduce the validator key list in the state transition - this is because we batch-check all signatures before entering the spec code, thus the spec code never hits the cache. A future refactor should _probably_ remove the threadvar altogether. There's a few other small fixes in here that make the flow easier to read: * fix `var ChainDAGRef` -> `ChainDAGRef` * fix `var QuarantineRef` -> `QuarantineRef` * consistent `dag` variable name * avoid using threadvar pubkey cache in most cases * better error messages in batch signature checking

reward accounting for altair+ (#2981) Similar to the existing `RewardInfo`, this PR adds the infrastructure needed to export epoch processing information from altair+. Because accounting is done somewhat differently, the PR uses a fork-specific object to extrct the information in order to make the cost on the spec side low. * RewardInfo -> EpochInfo, ForkedEpochInfo * use array for computing new sync committee * avoid repeated total active balance computations in block processing * simplify proposer index check * simplify epoch transition tests * pre-compute base increment and reuse in epoch processing, and a few other small optimizations This PR introduces the type and does the heavy lifting in terms of refactoring - the tools that use the accounting will need separate PR:s (as well as refinements to the exportred information)

Backfill support for ChainDAG (#3171) In the ChainDAG, 3 block pointers are kept: genesis, tail and head. This PR adds one more block pointer: the backfill block which represents the block that has been backfilled so far. When doing a checkpoint sync, a random block is given as starting point - this is the tail block, and we require that the tail block has a corresponding state. When backfilling, we end up with blocks without corresponding states, hence we cannot use `tail` as a backfill pointer - there is no state. Nonetheless, we need to keep track of where we are in the backfill process between restarts, such that we can answer GetBeaconBlocksByRange requests. This PR adds the basic support for backfill handling - it needs to be integrated with backfill sync, and the REST API needs to be adjusted to take advantage of the new backfilled blocks when responding to certain requests. Future work will also enable moving the tail in either direction: * pruning means moving the tail forward in time and removing states * backwards means recreating past states from genesis, such that intermediate states are recreated step by step all the way to the tail - at that point, tail, genesis and backfill will match up. * backfilling is done when backfill != genesis - later, this will be the WSS checkpoint instead

Collecting the time related stuff in one place makes it easier to find, avoids some circular imports and allows more easily identifying the code actually needs wall time to operate. * move genesis-time-related functionality into `spec/beacon_time` * avoid using `chronos.Duration` for time differences - it does not support negative values (such as when something happens earlier than it should) * saturate conversions between `FAR_FUTURE_XXX`, so as to avoid overflows * fix delay reporting in validator client so it uses the expected deadline of the slot, not "closest wall slot" * simplify looping over the slots of an epoch * `compute_start_slot_at_epoch` -> `start_slot` * `compute_epoch_at_slot` -> `epoch` A follow-up PR will (likely) introduce saturating arithmetic for the time units - this is merely code moves, renames and fixing of small bugs.

move quarantine outside of chaindag (#3124) * move quarantine outside of chaindag The quarantine has been part of the ChainDAG for the longest time, but this design has a few issues: * the function in which blocks are verified and added to the dag becomes reentrant and therefore difficult to reason about - we're currently using a stateful flag to work around it * quarantined blocks bypass the processing queue leading to a processing stampede * the quarantine flow is unsuitable for orphaned attestations - these should also should be quarantined eventually Instead of processing the quarantine inside ChainDAG, this PR moves re-queueing to `block_processor` which already is responsible for dealing with follow-up work when a block is added to the dag This sets the stage for keeping attestations in the quarantine as well. Also: * make `BlockError` `{.pure.}` * avoid use of `ValidationResult` in block clearance (that's for gossip)

singe validator key cache Instead of keeping a validator key list per EpochRef, this PR introduces a single shared validator key list in ChainDAG, and cleans up some other ChainDAG and key-related issues. The PR does not introduce the validator key list in the state transition - this is because we batch-check all signatures before entering the spec code, thus the spec code never hits the cache. A future refactor should _probably_ remove the threadvar altogether. There's a few other small fixes in here that make the flow easier to read: * fix `var ChainDAGRef` -> `ChainDAGRef` * fix `var QuarantineRef` -> `QuarantineRef` * consistent `dag` variable name * avoid using threadvar pubkey cache in most cases * better error messages in batch signature checking

The implementation works more or less the following way: * Validator pubkeys are singled out for monitoring - these can be running on the node or not * For every action that the validator takes, we record steps in the process such as messages being seen on the network or published in the API * When the dust settles at the end of an epoch, we report the information from one epoch before that, which coincides with the balances being updated - this is a tradeoff between being correct (waiting for finalization) and providing relevant information in a timely manner)

Backfill support for ChainDAG (#3171) In the ChainDAG, 3 block pointers are kept: genesis, tail and head. This PR adds one more block pointer: the backfill block which represents the block that has been backfilled so far. When doing a checkpoint sync, a random block is given as starting point - this is the tail block, and we require that the tail block has a corresponding state. When backfilling, we end up with blocks without corresponding states, hence we cannot use `tail` as a backfill pointer - there is no state. Nonetheless, we need to keep track of where we are in the backfill process between restarts, such that we can answer GetBeaconBlocksByRange requests. This PR adds the basic support for backfill handling - it needs to be integrated with backfill sync, and the REST API needs to be adjusted to take advantage of the new backfilled blocks when responding to certain requests. Future work will also enable moving the tail in either direction: * pruning means moving the tail forward in time and removing states * backwards means recreating past states from genesis, such that intermediate states are recreated step by step all the way to the tail - at that point, tail, genesis and backfill will match up. * backfilling is done when backfill != genesis - later, this will be the WSS checkpoint instead

handle duplicate pubkeys in sync committee (#2902) When sync committee message handling was introduced in #2830, the edge case of the same validator being selected multiple times as part of a sync subcommittee was not covered. Not handling that edge case makes sync contributions have a lower-than-expected participation rate as each sync validator is only counted up through once per subcommittee. This patch ensures that this edge case is properly covered.

move quarantine outside of chaindag (#3124) * move quarantine outside of chaindag The quarantine has been part of the ChainDAG for the longest time, but this design has a few issues: * the function in which blocks are verified and added to the dag becomes reentrant and therefore difficult to reason about - we're currently using a stateful flag to work around it * quarantined blocks bypass the processing queue leading to a processing stampede * the quarantine flow is unsuitable for orphaned attestations - these should also should be quarantined eventually Instead of processing the quarantine inside ChainDAG, this PR moves re-queueing to `block_processor` which already is responsible for dealing with follow-up work when a block is added to the dag This sets the stage for keeping attestations in the quarantine as well. Also: * make `BlockError` `{.pure.}` * avoid use of `ValidationResult` in block clearance (that's for gossip)

remove StateData (#3507) One more step on the journey to reduce `BlockRef` usage across the codebase - this one gets rid of `StateData` whose job was to keep track of which block was last assigned to a state - these duties have now been taken over by `latest_block_root`, a fairly recent addition that computes this block root from state data (at a small cost that should be insignificant) 99% mechanical change.
