v2.0.0-unstable.0

⚠️ You should not run this release on mainnet operators ⚠️

This release introduces support for the Alan fork to the SSV Holesky testnet.

Note: Alan databases are not backwards-compatible, meaning an upgraded node cannot downgrade without removing the database and syncing from scratch.

Upgrade Priority

Network	Priority	Alan Fork
Holesky	Mandatory	Oct. 8th 12:00 UTC (Epoch 84,600)
Mainnet	Don't upgrade ⚠️	TBD

Docker Tag

docker pull ssvlabs/ssv-node:v2.0.0-unstable.0

Intoducing Alan

Alan is the most significant SSV upgrade to date, poised to tackle scalability by dramatically reducing resource usage.

Alan changes the way a committee (group of operators) perform their validators's duties. Rather than performing every attestation and sync committee duty separately, a committee would perform them all together.

For more, see Meet Alan.

Other Changes

On top of Alan support, this release includes many fixes and improvements.

v1.3.7

This release includes a fix for cases where validators are registered while in a sync committee, alongside a performance optimization in how SSV retrieves validators from Beacon nodes.

Changes

• fix: refetch duties after metdata update (#1429)

v1.3.6

This release features a hotfix for block proposals with recent Lighthouse and Teku versions.

Upgrade Priority

Beacon Node	Version	Priority
Lighthouse	>= v5.2.0	⚠️ Mandatory
Teku	>= 24.4.0	⚠️ Mandatory
Others		⭐️ Strongly Recommended

⚠️ Upgrade to SSV v1.3.6 to avoid missing block proposals!

Note: Affected Teku users can safely remove the --validators-graffiti-client-append-format=DISABLED flag after upgrading to SSV v1.3.6

Brief

Recent Lighthouse and Teku versions began modifying the graffiti of block proposals to include EL/CL versions for client diversity analysis.

This caused a dependency we use to interact with Beacon nodes to reject block proposals from those Beacon nodes, because the returned graffiti was different than requested.

This hotfix removes this unnecessary constraint.

Changes

• #1438
• #1439

v1.3.5

This release includes an optimization which should accelerate the rate at which nodes form connections.

This should improve the performance of nodes after restarts, by helping them recover their ideal peer count quicker.

Changes

• refactor: low discovery interval

v1.3.4

This version includes two minor fixes that should improve performance in certain cases.

Fixes

• Registering a validator while its in sync committee no longer causes their operators to miss duties (#1432)
• Fixed external IP detection (#1433)

v1.3.3

This version introduces mainly optimizations to the consensus and message processing.

• By introducing OpenSSL for RSA signing we expect 10x faster signature verifications and lower CPU usage. As a side effect, memory usage should increase. Make sure to allocate at least as much RAM as is recommended in the docs (4 GB, as of this release).
  NOTE: This optimization is for Linux OS only.
• Enhancing consensus BLS verification by choosing an optimistic approach, verifying reconstructed messages and falling back to verify each one of the signatures if it fails.

Also fixed a bug that caused newly active validators to miss first epoch.

Expect fast consensus times and higher attestation rates.

IMPORTANT: Users running full nodes (exporters) should NOT update to this release.

Change log

• 🕒 Validator Startup: Fixed an issue to ensure validators start on time by using ActivationEpoch (#1347, @olegshmuelov).
• 🆔 Stale Operator ID Cases: Addressed and resolved remaining stale operator ID issues (#1240, @nkryuchkov).
• 🔏 Operator Key Encapsulation: Improved security by encapsulating operator keys (#1274, @nkryuchkov, @olegshmuelov, @y0sher, @moshe-blox).
• 💾 OperatorData Store: Introduced OperatorData store for efficient data management (#1356, @nkryuchkov, @moshe-blox, @y0sher).
• ✅ Signature Verification: Implemented partial signature verification aggregation to enhance performance (#1351, @nkryuchkov, @moshe-blox).
• ⚡ RSA Optimization: Utilized microsoft/openssl for RSA sign/verify operations to optimize performance (#1358, @y0sher, @moshe-blox).

v1.3.2

This hotfix contains additional updates to for the upcoming Deneb fork.

For this reason, we strongly urge operators to update to v1.3.2 on mainnet and all testnets.

Changes

• 🚧 voluntary exit signature in post-deneb networks (#1338)

v1.3.1

This release is a hotfix for Prysm users, fixing a block proposal bug which occurs in certain environments where Prysm returns JSON responses (rather than SSZ).

Affected users are those who run Prysm with an HTTP proxy and/or load balancer in-between Prysm and SSV.

Fixes

• update to use patched fixed go-eth2-client (#1334)

v1.3.0 — Dencun

This release is mandatory for all mainnet operators, as it's the first stable release for the upcoming Dencun fork.
