feat: include single attestations in producing blocks by twoeths · Pull Request #8076 · ChainSafe/lodestar

twoeths · 2025-07-23T08:25:56Z

Motivation

lodestar usually has too few attestations in its produced blocks and it has some rooms for improvement.
this PR tries to include missing SingleAttestations

Description

new SingleAttestation pool
- store 3 slots up to 32 63 slots depending on total attestation count capped by ~~100_000~~ 150_000 as analyzed in the PR
- the goal is to store less than 32 50 MB of SingleAttestations so that it does not affect performance of node
new getAttestationsForBlock, for each slot:
- get aggregated attestations from AggregatedAttestationPool
- if there are unseen committee members, continue with the new SingleAttestationPool
- consolidate attestations and sort
  Closes Include SingleAttestation when producing block #8028

TODOs

monitor on public networks. Does it affect memory, performance, how many more attestations included?
- new seen attesters metric tracked
- new attestation from SingleAttestationPool tracked
- performance when producing block is even better, performance for aggregated attestation validation is the same
- memory is really slow but I bound it to 50MB only
unit tests
left some TODOs for refactor work to make it less diffs to review. Need to work on that in the end ==> will do it in a separate PR
test on a real hoodi node to make sure produced blocks are included on chain: block 965135 is proposed by this branch

…t per slot

here are metrics on mainnet node (before and after I subscribe to all subnets)

there are more consolidations from the new SingleAttestationPool than the old AggregatedAttestationPool

as a result, there are more packed attestations in block, and it's mostly 8 after the node subscribed to all subnets

there are a big difference on new seen attesters after the node subscribed to all subnets

but time spent for attestation inclusion was actually reduced after the node subscribed to all subnets (because it reached max consolidations quickly, so it does not have to scan all slots)

memory of SingleAttestationPool was bound to 50MB, for a regular node it's almost nothing, and for a node subscribing to all subnets it's 1/4 of that capacity (ie it's < 12.5MB)

there is a minimal impact on aggregated attestation validation, see https://github.com/ChainSafe/lodestar/pull/8084/files#r2240237562

will separate this PR into 4 smaller PRs to make it easier to review:

enhance AggregatedAttestationPool ==> feat: enhance AggregatedAttestationPool #8095
implement SingleAttestationPool
main logic to get attestations for block production, populate SingleAttestationPool
refactor AggregatedAttestationPool after all: remove unused method, move common types/utils to better places

memory of SingleAttestationPool was bound to 50MB, for a regular node it's almost nothing, and for a node subscribing to all subnets it's 1/4 of that capacity (ie it's < 12.5MB)

* there is a minimal impact on aggregated attestation validation, see https://github.com//pull/8084/files#r2240237562

It looks like that 150_000 cap is only enforced during prune and not add. So the 50MB is not a hard bound per se as it can go over 50MB during the slot.
I guess the worst case is there is zero aggregated attestations on the network and all SingleAttestations. For 1 million active validators, there will be 1000000 / 32 = 31250 single attestations, and it will add 31250 * 316 bytes = 9.42MB. So the largest size SingleAttestationPool can reach is 59.42MB, which will be pruned to 50MB onClockSlot. Still nothing significant in my opinion.

Do we still have MIN_SLOTS_RETAINED mechanism? It looks like prune() will prune all attestations except those for current epoch and last epoch, and then prune down to MAX_ATTESTATIONS_RETAINED

I did have MIN_SLOTS_RETAINED then removed since I switched to only store not-seen attestations
I don't see the use of it anymore. In unfinality time it's more important to keep the node stable than trying to find not-seen attestations to include in block

For single attestations this strategy seems fine as it's not likely they will represent a lot of weight
