ssvlabs/ssv-dkg v3.1.0

DKG v3.1.0

on GitHub

All operators in a ceremony must run the same version.
v3.0.x ↔ v3.1.0 mixed ceremonies will fail — exact version match is enforced.
Coordinate upgrades across your operator set.

Features

• 0x02 compounding withdrawal credentials (Pectra/EIP-7251) via --compounding flag (#222, #223)

Security

• HTTP request body capped at 105 MiB (#224)
• MaxInstances reduced 102400 → 1024 (DoS) (#226)
• Nonce widened uint16 → uint64 in signature verification (#227)
• Internal error text no longer exposed in error responses (#228)
• HTTP handler goroutines no longer block forever (#229)
• Out-of-order DKG message deadlock removed (#230)
• Healthcheck pong signature verification fixed (#231)
• Resign rejects mismatched owner address (dkg-spec v1.2.0, dkg-spec#31)

Fixes

• EIP-1271 contract signature ABI corrected to isValidSignature(bytes32,bytes) (dkg-spec v1.2.0, dkg-spec#29)

Infrastructure

• Docker Hub multi-arch (amd64 + arm64) automated publishing (#232)

Breaking

• ping requires --operatorsInfo or --operatorsInfoPath (was --ip alone)
• Error responses no longer leak internal error text — clients parsing error message strings must update

Upgrade

• docker pull ssvlabs/ssv-dkg:v3.1.0
• Update any ping scripts to include --operatorsInfo
• Coordinate with your operator set before running ceremonies on v3.1.0
