⚠️ 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

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.
