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

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

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

v23.5.1

Notes

Nimbus v23.5.1 is a medium-urgency point release improving the compatibility of Nimbus with 3rd party validator clients and beacon nodes and introducing the support for incremental pruning. If you are still not using the --history:prune option, we recommend testing it in a non-production environment, as it will be enabled by default in our next release.

Breaking changes

• The Nimbus validator client no longer accepts under-specified beacon node URLs that doesn't include a port number or a protocol scheme. When a protocol scheme is specified, Nimbus now uses the default port for the selected protocol (80 for HTTP and 443 for HTTPS):
  #4921

Improvements

• The history pruning is now incremental and no longer results in start-up delays when the --history:prune option is enabled on an existing node:
  #4887

• Nimbus now uses the withdrawal address of the validator as a default choice for the fee recipient address if the user has not provided any value in the configuration:
  #4968

• Nimbus now supports the upcoming Capella hard-fork in the Gnosis network:
  #4936

Fixes

• The Capella-related properties MAX_BLS_TO_EXECUTION_CHANGES, MAX_WITHDRAWALS_PER_PAYLOAD, MAX_VALIDATORS_PER_WITHDRAWALS_SWEEP and DOMAIN_BLS_TO_EXECUTION_CHANGE were missing from the /eth/v1/config/spec REST API end-point:
  #4925

• The /eth/v1/validator/blinded_blocks/{slot} was supplying incorrectly encoded response when requested to return SSZ data:
  #4943

• The safety checks associated with the --weak-subjectivity-checkpoint parameter are now compliant with the latest Ethereum specs:
  #4923

• The Nimbus validator client was using HTTP pipelining which is not supported by all beacon node implementations:
  #4950

• The "Connection to EL node degraded" warning is now printed only after sufficiently persistent connectivity issues with the EL client:
  #4960

• After being only briefly disconnected from the execution layer client, the Nimbus beacon node was prematurely setting the execution_optimistic flag when returning validator duties:
  #4955

• Nimbus now allows the builder to respond 500ms later than the spec-mandated timeout in order to account for possible additional delays introduced by proxies such as mev-boost:
  #4964

• During sync committee period transitions, for a brief period of time there was a low risk of producing an invalid sync committee contribution:
  #4953

• Nimbus v23.5.0 introduced an unintended backwards-incompatible change in the parsing of remote keystores which is addressed in this release:
  #4967

---

Nimbus v23.5.0 was a medium-urgency upgrade that addresses a critical issue which was introduced in the previous version (v23.4.0). The issue was causing missed block proposals for users who were utilizing an external builder.

Improvements

• After Nimbus completes a trusted node sync executed with the --trusted-block-root flag, it will enable signature verification of all backfilled blocks, thereby reducing the assumed trust in the specified beacon node URL to merely expected data availability rather than expected data authenticity:

  #4858

• The /eth/v1/node/syncing BeaconAPI endpoint now supports the standardized el_offline property:

  #4860
  ethereum/beacon-APIs#290

• The secp256k1 library has been upgraded to version 0.3.1.

• Nimbus now supports an experimental extension of the Web3Signer protocol, allowing the signer server to verify certain properties of the signed block, such as the specified fee recipient:

  https://nimbus.guide/web3signer.html#verifying-web3signer
  #4775
  #4912

Fixes

• Nimbus was submitting blocks with incorrect state root to the attached external builder which resulted in missed block proposals:

  #4889

• Nimbus was skipping block proposals due to an inappropriate triggering of the slashing protection logic when an external builder was providing a block with insufficient value to be selected under the new --local-block-value-boost mechanism:

  #4894

• Nimbus was crashing after certain unsuccessful requests to the external block builder:

  #4890

• The Nimbus validator client was failing to perform sync committee duties when attached to multiple beacon nodes and when some of them were only optimistically synced:

  #4878

• The --trusted-block-root option was not visible in the trustedNodeSync help listing:

  #4859

• Nimbus was experiencing sporadic request time outs when being connected to the execution client over HTTP. Under specific circumstances this was introducing risk for missed attestation:

  d784672

• The required traffic to the execution client was reduced by preventing the sending of the same block multiple times:

  #4850

v23.5.0

Notes

Nimbus v23.5.0 is a medium-urgency upgrade that addresses a critical issue which was introduced in the previous version (v23.4.0). The issue was causing missed block proposals for users who were utilizing an external builder.

Improvements

• After Nimbus completes a trusted node sync executed with the --trusted-block-root flag, it will enable signature verification of all backfilled blocks, thereby reducing the assumed trust in the specified beacon node URL to merely expected data availability rather than expected data authenticity:

  #4858

• The /eth/v1/node/syncing BeaconAPI endpoint now supports the standardized el_offline property:

  #4860
  ethereum/beacon-APIs#290

• The secp256k1 library has been upgraded to version 0.3.1.

• Nimbus now supports an experimental extension of the Web3Signer protocol, allowing the signer server to verify certain properties of the signed block, such as the specified fee recipient:

  https://nimbus.guide/web3signer.html#verifying-web3signer
  #4775
  #4912

Fixes

• Nimbus was submitting blocks with incorrect state root to the attached external builder which resulted in missed block proposals:

  #4889

• Nimbus was skipping block proposals due to an inappropriate triggering of the slashing protection logic when an external builder was providing a block with insufficient value to be selected under the new --local-block-value-boost mechanism:

  #4894

• Nimbus was crashing after certain unsuccessful requests to the external block builder:

  #4890

• The Nimbus validator client was failing to perform sync committee duties when attached to multiple beacon nodes and when some of them were only optimistically synced:

  #4878

• The --trusted-block-root option was not visible in the trustedNodeSync help listing:

  #4859

• Nimbus was experiencing sporadic request time outs when being connected to the execution client over HTTP. Under specific circumstances this was introducing risk for missed attestations:

  d784672

• The required traffic to the execution client was reduced by preventing the sending of the same block multiple times:

  #4850

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

v23.4.0

Notes

Nimbus v23.4.0 is a medium-urgency upgrade addressing a number of low probability risks for missed block proposals, bringing performance improvements in setups relying on the Nimbus validator client, and introducing some exciting new capabilities of the Nimbus light client and Builder API implementations.

Improvements

• Nimbus now obtains blocks from the configured builder and execution layer nodes without providing timing advantage to any source. You can use the newly added --local-block-value-boost option to give preference to the best block provided by an execution layer node, as long as its value is within the specified percentage of the value advertised by the best external builder. Setting this flag to a non-zero value is recommended because the usage of an external builder introduces an additional risk that the advertised block won't be published by the builder:

  #4749
  #4795
  #4847

• Nimbus now supports the standardized Builder API liveness failsafe mechanism:

  #4746

• The --sync-light-client option is now enabled by default, providing significant speedups in beacon chain syncing and re-syncing:

  #4805

• The trustedNodeSync command features a new --trusted-block-root option that leverages the Nimbus light client in order to minimize the required trust in the specified Beacon API endpoint. After downloading the state snapshot, the light client will verify that it conforms to the established consensus in the network. Note that the provided --trusted-block-root should be somewhat recent, and that additional security precautions such as comparing the state root against block explorers are still recommended.

  #4736

• Improved scheduling mechanisms in the Nimbus validator client deliver stability and performance improvements:

  #4743

• The deposits exit command can now be used to perform voluntary exits for multiple validators at once:

  #4855
  https://nimbus.guide/voluntary-exit.html

• Nimbus now supports the /eth/v1/beacon/states/{state_id}/randao REST API endpoint:

  #4799

• Nimbus now uses only the Capella-enabled engine_forkchoiceUpdatedV2 endpoint in all communication with the execution layer:

  #4817

Fixes

• Nimbus has addressed a risk of missed block proposal due to incorrectly computed withdrawals at epoch boundaries:

  #4820

• Nimbus has addressed a low probability risk of missed block proposals when the configured builder doesn't respond in time:

  #4764

• Nimbus has addressed a low probability risk of missed block proposals when a late block triggers a chain re-org while an engine_forkchoiceUpdated request to the execution layer is in flight:

  #4800

• Nimbus will no longer experience occasional response timeouts when performing a large number of concurrent HTTP requests (e.g. when configured to operate with a large number of remote keystores):

  status-im/nim-presto#44
  status-im/nim-chronos#324
  #4779

• The Nimbus validator client will no longer crash on start-up when supplied with incorrect beacon node configuration:

  #4765

• Nimbus will no longer crash when there is a network mismatch between the imported slashing protection database and the specified data directory:

  #4791

• Inactive validators will no longer affect the initial GossipSub topic subscriptions:

  #4793

• Failed or timed out request to engine_exchangeTransitionConfigurationV1 will no longer degrade the status of the connection to the execution layer:

  #4831

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
