Breaking Changes
- Updated counter metrics to incorporate the suffix
_total
. If you are using a custom dashboard to monitor Teku metrics, you might need to update the metrics manually when breaking changes are introduced. For more information, see Update metrics. - Java 21+ is required to be installed to run Teku. Refer to https://docs.teku.consensys.io/get-started/install for the updated instructions.
Additions and Improvements
- Added support for dual-stack (IPv4/IPv6) for discovery and p2p. Refer to https://docs.teku.consensys.io/development/how-to/find-and-connect/configure-ipv6 for more details.

Breaking Changes
Additions and Improvements
Bug Fixes
- Fixed an issue from version 24.6.0 where Teku failed to start on machines with directly assigned public IP addresses (not running under NAT), displaying the error message:
Teku failed to start: java.io.UncheckedIOException: java.net.UnknownHostException: Unable to determine local IPvx Address
Upcoming Breaking Changes
- Next release will introduce a breaking change to Teku's metrics. This is due to some metrics changing names after a library upgrade.
We recommend all users of theTeku - Detailed
dashboard to upgrade to version Revision 12
as soon as possible. Documentation with all metrics that have been renamed will be provided. - Next release will require Java 21. The current release is compatible, please consider upgrading before the next release.
- From the next release, you will need to explicitly set
--data-storage-mode=(prune|archive)
unless you're using minimal data-storage-mode (which is the default behaviour).

Breaking Changes
- Renamed
--Xp2p-dumps-to-file-enabled
hidden CLI option to--Xdebug-data-dumping-enabled
Additions and Improvements
- Added metadata fields to
/eth/v1/beacon/blob_sidecars/{block_id}
Beacon API response as per ethereum/beacon-APIs#441 - Added rest api endpoint
/teku/v1/beacon/state/finalized/slot/before/{slot}
to return the slot of the most recently stored state at or before the specified slot. - The validator client will start using the
v2
variant of the beacon node block publishing
endpoints. In the cases where the block has been produced in the same beacon node, only equivocation validation will be done instead of the entire gossip validation. - Docker images are now based on ubuntu 24.04 LTS (noble)
- The
teku vc
subcommand fails when no validator key source is provided. In order to run a validator client, one of the following options must be set:
--validator-keys
,--validators-external-signer-url
or--validator-api-enabled
- Updated dependencies.
Bug Fixes
- Fixed performance degradation introduced in 24.4.0 regarding archive state retrieval time.
- Fixed file writer when storing database mode settings to file (related to #8357).

Breaking Changes
- Removed support for the Goerli network
--network=goerli
.
Additions and Improvements
- Increased the executor queue default maximum size to 40_000 (previously 20_000), and other queues to 10_000 (previously 5_000). If you have custom settings for these queues, check to ensure they're still required.
- Added
peers_direction_current
libp2p metric to track the number of peers by direction (inbound and outbound). - Deposit tree snapshots will be loaded from database as a default unless custom snapshot has been provided.
- Added hidden option
--Xdeposit-contract-logs-syncing-enabled
to allow disabling the syncing of the deposit contract logs from the EL. This is useful when running a non-validating node. It is advisable to be used alongside with--Xeth1-missing-deposits-event-logging-enabled=false
to avoid unnecessary logging of missing deposits. - Updated the bootnodes for Chiado and Gnosis networks.
- Added hidden option
--Xp2p-dumps-to-file-enabled
to enable saving p2p dumps to file. - Consensus layer (CL) and execution layer (EL) clients' information will be appended to the validator graffiti. Check documentation for the available configuration options.
- Added support for Graffiti management in the Key Manager API.

24.3.1
This is a recommended update for mainnet nodes with improvements to CPU and bandwidth issues observed since Deneb upgrade.
Key changes:
- Updated libp2p seen cache configuration reducing CPU and bandwidth consumption
- Increased attestation cache capacity to improve block building
- Introduced Validator Slashing Prevention feature
- Fixed issue between Teku Validator Client and Lighthouse Beacon Nodes

Breaking Changes
- The development command line argument
--Xvalidator-is-local-slashing-protection-synchronized-enabled
has become a supported and documented argument--validator-is-local-slashing-protection-synchronized-enabled
.
Additions and Improvements
- Introduced Validator Slashing Prevention feature.
- If the EL supports the
engine_getClientVersionV1
Engine API method, the default graffiti (when no graffiti has been configured by the validator) will include EL as well as CL version information. For more details, please see ethereum/execution-apis#517. --p2p-private-key-file
command line option supports reading a binary private key file.- Updated libp2p seen cache configuration to reflect EIP-7045 spec changes. This reduces CPU and network bandwidth consumption.
- Increased the attestation cache capacity to allow Teku a bigger pool of attestations when block building.
- Defaulted
--builder-bid-compare-factor
to 90. This makes it necessary for external block builders to give at least 10% additional profit compared to a local build before being taken into consideration. If you would like to go back to the previous default, set--builder-bid-compare-factor
to 100. - Added
--p2p-direct-peers
command line option to configure explicit peers as per Explicit Peering Agreements libp2p spec.
Bug Fixes
- Fix incompatibility between Teku validator client and Lighthouse beacon nodes #8117

Breaking Changes
- When a lock file is unable to be cleaned up, the (BN or VC) will now exit code 2 in preference to being 'up' but not able to perform duties. This will not self recover and will need intervention from the node operator.
Additions and Improvements
- Improve block rewards calculation performance for
/eth/v3/validator/blocks/{slot}
block production beacon node API. - Updated Javalin to v.6 (used by rest-api and keymanager-api).
- Docker image tags now default to jdk21 images unless a jdk-specific tag is used.
Bug Fixes
- Fixed an issue where stale lock files weren't able to be cleaned up and would effectively park the service (BN or VC) with no user errors or any indication that the service was in a bad state.
24.2.0
Changelog
This is a required update for Mainnet users containing the configuration for the Deneb upgrade on March 13th. This update is required for Gnosis Deneb network upgrade on March 11th. For all other networks, this update is optional.
Attention: Teku will require around 50 GB of extra storage for blobs for Mainnet (35 GB for Gnosis), but theoretically blob storage requirements can go up to ~100 GB (200 GB for Gnosis). This extra storage space WILL NOT grow above this limit over time.
For more information about blobs, please have a look at the following page: https://docs.teku.consensys.io/concepts/proto-danksharding

Breaking Changes
- The CLI options
--beacon-events-block-notify-when-validated-enabled
and
--beacon-events-block-notify-when-imported-enabled
have been removed. This change was made due
to redundancy, as the functionality of these options is now covered by the newblock_gossip
and
the existingblock
SSE events.
Additions and Improvements
- Updated Mainnet configuration with Deneb fork scheduled for epoch 269568 (March 13, 2024, 13:55:35 UTC)
- Updated Gnosis configuration with Deneb fork scheduled for epoch 889856 (March 11, 2024, 18:30:20 UTC)
- Improved compatibility with
/eth/v3/validator/blocks/{slot}
experimental beacon API for block production. It can now respond with blinded and unblinded content based on the block production flow. It also supports thebuilder_boost_factor
parameter. - Add
block_gossip
SSE event as per ethereum/beacon-APIs#405 - Deposit tree snapshots will be downloaded from checkpoint-sync-url when available #7715
- Applied fork-choice confirmation rule prerequisite change outlined in ethereum/consensus-specs#3431.
24.1.1
Changelog
This is a required update for Sepolia, Holesky and Chiado. Optional for other networks.
Attention: Teku will require around 50 GB (35 GB for Chiado) of extra storage for blobs, but theoretically blob storage requirements can go up to 103 GB (200 GB for Chiado). This extra storage space WILL NOT grow above this limit over time.

Additions and Improvements
- Added a hidden flag
--Xfork-choice-updated-always-send-payload-attributes
which would cause payload attributes to be calculated and sent with every fcU. This could be useful for builders consuming thepayload_attributes
SSE events. - Added Deneb (aka Dencun) configuration for Sepolia network for epoch 132608 (2024-01-30 22:51:12 UTC).
- Added Deneb (aka Dencun) configuration for Chiado network for epoch 516608 (2024-01-31 18:15:40 UTC).
