v24.1.0

Notes

Nimbus v24.1.0 is a low-urgency upgrade bringing full support for the upcoming Cancun-Deneb hard-fork on the Goerli testnet and introducing the /eth/v3/validator/blocks/{slot} Beacon API end-point that greatly simplifies the implementation of profit-optimising validator clients.

Improvements

• Nimbus now includes the latest Goerli-Prater metadata, scheduling the Cancun-Deneb hard-fork:
  #5680

• The Nimbus beacon node now supports the /eth/v3/validator/blocks/{slot} Beacon API end-point:
  #5474
  https://ethereum.github.io/beacon-APIs/?urls.primaryName=dev#/Validator/produceBlockV3

• Nimbus now accepts POST requests to the /eth/v1/beacon/states/{state_id}/validators and /eth/v1/beacon/states/{state_id}/validator_balances Beacon API end-points:
  #5632
  ethereum/beacon-APIs#367

• Nimbus now follows the latest specification regarding the deprecated /eth/v1/validator/blinded_blocks/{slot} Beacon API end-point:
  #5639

• Nimbus now uses the latest set of bootstrap nodes for the Gnosis chain:
  #5656

Fixes

• Nimbus was sending unnecessary redundant forkChoiceUpdated notifications to the execution layer:
  #5635

• Nimbus was returning incorrect responses on requests for blocks at empty slots when working with ERA files:
  #5641

• The Nimbus validator client was not sending Builder API registration messages at the correct time:
  #5663

• Nimbus was ignoring a specified --jwt-secret option when no --el option was provided and the default localhost URL was being used:
  #5671
  #5665

Breaking Changes

• Machine consumers of Nimbus logs should be updated, as the abbreviated value of the NOTICE log level has been renamed from NOT to NTC:
  #5634

Urgency guidelines

low-urgency: update at your own convenience, sometime within our normal update cycle of two weeks

medium-urgency: may contain an important stability fix, it is better to update sooner rather than later

v23.11.0

Notes

Nimbus v23.11.0 is a low-urgency upgrade bringing enhanced support for the Obol DVT middleware, further profit optimisations for the Nimbus validator client and a simplified and safe alternative to the trusted node sync.

Improvements

• The new options external-beacon-api-url, trusted-block-root and trusted-state-root enable simple bootstrapping through the light client protocol and a non-trusted Beacon API provider:
  https://nimbus.guide/start-syncing.html#checkpoint-sync
  #5545

• Improved scoring algorithms allow the Nimbus validator client to maximize block rewards when working with multiple beacon nodes:
  #5447

• Nimbus now supports the /eth/v1/validator/beacon_committee_selections and /eth/v1/validator/sync_committee_selections Beacon API endpoints used by the Charon Obol middleware:
  #5375

• Efficient bulk write operations to the slashing protection database bring significant performance improvements when operating very large number of validators on a single machine (e.g. more than 10K):
  #5604

• Nimbus now disconnects peers who are behaving poorly with respect to the beacon chain request/response protocols and peers who are exceeding the GossipSub rate limits:
  #5579
  #5482

• The Nimbus guide now features light and dark themes:
  #5564

• Nimbus now honours the MIN_EPOCHS_FOR_BLOCK_REQUESTS network configuration parameter:
  #5590

Fixes

• The REST API endpoint /eth/v1/node/peers_count was producing an incorrectly encoded numeric response:
  #5548

• The REST API endpoint eth/v2/beacon/blocks was not handling the broadcast_validation parameter in accordance to the spec:
  #5531

• The validator client slashing database was not pruned:
  #5551

• Light clients following the event stream of light client updates delivered through the REST API or the P2P protocols were at risk of getting stuck due to missing notifications for certain key events:
  #5602
  ethereum/consensus-specs#3549

• Regression in v23.10.0 was preventing the Nimbus validator client from registering its validators with the external builder when no validators have been attached to the associated beacon node, effectively disabling the usage of the builder:
  #5603

• Nimbus was not retrying certain syncing requests after receiving an invalid response from a peer:
  #5615

• A theoretical possibility where Nimbus may fail to start after a clean shutdown has been addressed:
  #5617

v23.10.0

Notes

Nimbus v23.10.0 is a low-urgency upgrade focusing on stability and performance improvements. The performance improvements will be most impactful on networks with a large number of validators such as the Holešky testnet.

Improvements

• Faster attestation packing algorithm reduces the risk of orphaned block proposals:
  #5471

• Nimbus now adjusts its own the file descriptor limits on start-up in order to reduce the risk of running out of file descriptors:
  #5436

• The Keymanager API now imports keystores faster when they are encrypted with the same password and salt (this is typical for keystores produced by the staking-deposit-cli tool):
  #5443

• The Beacon API now emits the spec-mandated finalized field on all relevant endpoints:
  #5422

• Faster SSZ hashing speed reduces the overall CPU usage of the client:
  #5463

• The list of mainnet bootstrap nodes has been expanded:
  #5472

• A more efficient algorithm for calculating the list of block proposers during the epoch reduces the risk of missed validator duties during the first slot of the epoch:
  #5414

• Nimbus now produces more detailed error messages when it fails to load validator keystores:
  #5480

• The options --verifying-web3-signer-url and --proven-block-property can be used in place of --web3-signer-url to leverage the support for the experimental Verifying Web3Signer protocol extension:
  https://nimbus.guide/web3signer.html#verifying-web3signer
  #5504

Fixes

• A rarely occurring file descriptor leak was degrading the performance of Nimbus over time in certain environments:
  #5394

• Nimbus was not properly maintaining connectivity to peers specified through the --direct-peer option. Besides the format /ip4/<address>/tcp/<port>/p2p/<peerId-public-key>, the option now also accepts ENR addresses:
  #5427

• Nimbus was rejecting some valid sync committee contributions during the first slot of every sync committee period (once per 27 hours):
  #5408

• The Nimbus validator client will no longer crash when the indicated beacon node hostname cannot be resolved:
  #5388

• The fork-choice algorithm was performing certain computations multiple times:
  #5437

• Nimbus was sending unnecessary validator registrations to the builders when configured with multiple per-validator builder preferences:
  #5431

• The Nimbus validator client was not able to process responses from a Teku beacon node replying to the /eth/v1/validator/liveness/{epoch} endpoint, due to the presence of additional non-standardized fields:
  #5418

• The Beacon API was using non-compliant HTTP status codes in case of invalid requests to certain endpoints:
  #5422

v23.9.0

Notes

Nimbus v23.9.0 is a low-urgency upgrade providing full support for the upcoming Holešky testnet and simplifying the required configuration for using remote signers.

We've been hard at work researching and developing a GossipSub protocol upgrade, designed to vastly improve bandwidth and latency, especially when dealing with the upcoming larger EIP-4844 blob messages. This release introduces the initial steps towards this upgrade, along with CPU optimizations and enhanced DDoS protection.

Improvements

• The GossipSub implementation of Nimbus now consumes less bandwidth and CPU cycles, while improving upon the existing DoS protections through better peer scoring:
  #5229

• The new --web3-signer-url command-line option can be used to connect Nimbus to one or more remote signers without requiring any remote keystore files to be created. The list of validators attached to each remote signer is obtained automatically through the /api/v1/eth2/publicKeys Web3Signer API endpoint:
  #5366
  #5385
  #5389

• Nimbus now supports the upcoming Holešky testnet:
  https://nimbus.guide/holesky.html
  #5337

• Faster validator registry processing reduces the time spent by Nimbus in state transitions and replays:
  #5412

Fixes

• The deposits exit command was failing due to incorrect parsing of certain fields in the response of the /eth/v1/config/spec endpoint:
  #5370
  #5371

v23.8.0

Notes

Nimbus v23.8.0 is a low-urgency upgrade focusing on performance and stability improvements, aiming to address the increasing number of validators on mainnet and upcoming testnets such as Holesky.

Please note that this version enables the new attestation subnet subscription logic, proposed in the Ethereum 1.4 consensus spec. This will significantly reduce the CPU usage and the consumed network bandwidth on beacon nodes with many validators, but it will slightly increase them on nodes with a single validator. The --subscribe-all-subnets option can still be used on powerful hardware configurations to produce potentially more profitable blocks by processing all attestations directly instead of relying on aggregators.

The upgraded BLST library now identifies your CPU model and selects the most efficient instruction set at run-time which significantly speeds up docker and binary builds. We have tested this on a wide range of hardware, but should the CPU incorrectly advertise extensions it does not have, a downgrade might be necessary while we investigate.

Improvements

• Optimised algorithms and improved thread scheduling strategy allow Nimbus to process 40% more incoming attestations on typical hardware configurations:
  #5288
  #5176

• Faster state replays and lower latency Beacon API responses are now possible due to lower overhead when loading any kind of data from the Nimbus database. This was achieved through more efficient SSZ deserialization routines, the elimination of redundant CRC checks during data decompression and more precise cache invalidation:
  #5207
  #5264
  #5282

• A more optimised SSZ hash tree root implementation brings faster state replays, block processing and other performance-critical operations in Nimbus:
  status-im/nim-ssz-serialization#53
  #5292

• Nimbus now performs less memory allocations during state transitions, reducing the risk of delays induced by Nim garbage collection:
  #5235

• The BLST library has been upgraded to its latest version. Nimbus is now using a more optimal approach to aggregate signature verification:
  #5272
  #5268

• Nimbus now supports the Chiado Gnosis testnet:
  #5208

• BearSSL has been upgraded to version 0.2.1:
  #5298

Fixes

• Nimbus was not compliant with the latest Web3Signer specification when requesting block signatures:
  #5294

• The Nimbus beacon node was frequently crashing immediately after block proposal when using a validator client and an external builder:
  #5295

• The Nimbus validator client was crashing in certain situations after a request to the beacon node has timed out:
  #5297

• Nimbus was failing to load a built-in genesis state of a supported network on certain ARM CPUs:
  #5244

• When optimistically synced, Nimbus was sending unnecessary forkChoiceUpdated notifications for already finalized blocks:
  #5248

Removed functionality

• The builder API is no longer supported in network simulations and custom testnets, based on the Bellatrix specification:
  #5162
  #5203
  #5251
  #5262
  #5272

v23.7.0

Notes

Nimbus v23.7.0 is a low-urgency upgrade, bringing advanced profit optimisation capabilities to the Nimbus validator client and addressing risk factors that can contribute to poorer validator performance.

Improvements

• The Nimbus validator client now uses a scoring algorithm capable of selecting the most optimal attestation data when working with multiple beacon nodes:
  #5101

• The Nimbus validator client now synchronizes its clock with the Nimbus beacon node in order to eliminate any risks for poor validator performance stemming from de-synchronized clocks:
  #4846

• The /eth/v1/beacon/states/{state_id}/* family of REST end-points now support queries by state root as long as the state is within the most recent 8192 slots (approximately 27 hours):
  #5155

• Improved validation of blocks during syncing allows Nimbus to optimize the initial syncing target of the execution layer node:
  #5169

• The Nimbus light client is now available a C library for easy reuse and embedding in other software (alpha release):
  #5122

Fixes

• Due to multiple reports of slow start-up times on certain hardware configurations, caused by the one-time initial pruning performed by Nimbus v23.6.0 and v23.6.1, this functionality has been temporarily disabled:
  #5191

• The block monitoring performed by the Nimbus validator client was permanently interrupted in certain situations after a timed out request to the beacon node:
  #5109

• Nimbus now uses the most up-to-date bootstrap nodes for the Gnosis chain:
  #5175

• Nimbus has addressed a minor risk for missed block proposals at epoch boundaries due to multiple compounding risk factors:
  #5195
  #5196
  #5194

v23.6.1

Notes

Nimbus v23.6.1 is a low-urgency point release significantly improving the performance of database pruning on Nimbus instances that have accumulated history prior to April 2021 (Nimbus 1.1.0). Affected users are advised to upgrade as soon as possible in order to reduce the risk of missed attestations and blocks.

Fixes

• The legacy Nimbus database is not subjected to pruning due to the high I/O cost of the operations:
  #5116

---

Nimbus v23.6.0 was a medium-priority upgrade, further improving the efficiency and the standards-compliance of Nimbus while laying out the foundations for the upcoming Deneb hard-fork.

Improvements

• The --history:prune option is now enabled by default.

• Nimbus can now process untimely attestations without triggering expensive state replays, resulting in increased resilience:
  #4911

• The Keymanager API can now be used to perform voluntary exits:
  #5020
  https://ethereum.github.io/keymanager-APIs/?urls.primaryName=dev#/Voluntary%20Exit

• The Nimbus validator client now leverages the more efficient support for SSZ responses of the Beacon API:
  #4999

• Full support for the upcoming Shapella hard-fork on the Gnosis chain:
  #5114

Fixes

• The support for interacting with the Beacon API from CORS-enabled clients has been restored:
  #5028

• The Nimbus beacon node will no longer inappropriately report el_offline=true when fully synced:
  #4991

• The Nimbus validator client will no longer occasionally fail to perform sync committee duties in the first slot of every epoch:
  #5083
  #5084

• Nimbus will no longer refuse to import certain valid SPDIR files (slashing protection interchange format):
  #4997

• The Nimbus behavior differed in minor ways from the Ethereum's fork-choice and honest validator specifications:
  #4992
  #5002

• The Nimbus beacon node was leaking a small amount of memory during a build-up of peer-to-peer block syncing requests:
  #4697

• The Nimbus validator client is now compatible with Lighthouse beacon nodes as it no longer exceeds the maximum allowed number of validator indices per request to the /eth/v1/beacon/states/{state_id}/validators endpoint:
  #5082

  We are deeply grateful to @jshufro for contributing important fixes in two consecutive Nimbus releases!

Removed functionality

• The implementation of the phase0-specific Beacon API endpoint /eth/v1/debug/beacon/heads has been removed:
  #5058

• The Web3Signer support for performing the phase0-specific V1 block signing requests has been removed:
  #5014

Urgency guidelines

low-urgency: update at your own convenience, sometime within our normal update cycle of two weeks

medium-urgency: may contain an important stability fix, it is better to update sooner rather than later

high-urgency: update as soon as you can, this is a critical update required for Nimbus to function correctly
