v1.0.0 - 2024-07-1

Obol Logo

This is Charon's first major release!

As detailed by our version compatibility, Charon v1.0.0 is not fully-backwards compatible with v0.x.x releases. Block proposals are not compatible between the versions, so once your cluster begins the upgrade, please upgrade all nodes promptly to ensure readiness for a proposal opportunity should one occur.

Breaking changes

  • Full support for beacon spec produceBlockV3 endpoint has been implemented: DutyProposer supports now both blinded and unblinded blocks, while DutyBuilderProposer has been deprecated.
    • This means you should remove the extra validator configuration added during previous versions of charon, consult the prior release to see what flags to remove to default to the lastest version of block proposals.

Migration notes

  • Make sure that your validator client of choice supports produceBlockV3, and that you re-enable it by either removing or toggling all the flags we detailed in v0.19.2 release notes:

    • Lodestar: --useProduceBlockV3=true as CLI parameter at startup
    • Lighthouse: --produce-block-v3 as CLI parameter at startup
    • Teku: --Xblock-v3-enabled=true as CLI parameter at startup

  • If you run Nimbus as a validator client, make sure to pass --feature-set-enable=json_requests as CLI parameter to charon run at startup

  • If you run Teku as a beacon node, add the flag --validators-graffiti-client-append-format=DISABLED to it.

Compatibility Matrix

This matrix details the combination of beacon node + validator clients and their corresponding versions the Obol team have tested with this charon release. More validator and consensus client will be added to this list as they are supported in our automated testing framework.

Legend

  • ✅: All duties succeed in testing
  • 🟡: All duties succeed in testing, except non-penalised aggregation duties
  • 🟠: Duties may fail for this combination

Consensus 👇 Validator 👉 Teku v24.6.1 Lighthouse v5.2.11 Lodestar v1.19.0 Nimbus v24.5.1 Prysm PR Remarks
Teku v24.6.1 ✅ 🟡 ✅ ✅ ✅ Teku bn needs the --validators-graffiti-client-append-format=DISABLED flag in order to produce blocks properly.
Lighthouse v5.2.1 ✅ 🟡 ✅ ✅ 🟠 Lighthouse vc are only failing aggregation duties, which are not directly penalised but impact network density at high scale.
Nimbus v24.5.1 🔴 🟡 ✅ ✅ ✅ Nimbus beacon nodes requires that you add the following flag to charon run: charon run --feature-set-enable=json_requests
Prysm v5.0.3 ✅ 🟡 ✅ ✅ ✅ Prysm validator needs a particular pull request merged and released for aggregation duties to succeed.
Lodestar v1.19.0 ✅ 🟡 ✅ ✅ ✅
