Executive Overview

What is Symbiotic Relay?​

The Symbiotic Relay system implements a complete signature aggregation workflow from validator set derivation through on-chain commitment of the ValSetHeader data structure. This allows for provable attestation checks on any chain of an arbitrary data signed by the validator set quorum

Technology Foundation​

Symbiotic Relay is a peer-to-peer side-network designed to collect and aggregate signatures from validators maintaining validator sets on settlement contracts (potentially on other chain than where the actual stakes are), while keeping funds safe in the Symbiotic Core.

The system provides a modular smart contract framework that enables networks to manage validator sets dynamically, handle cryptographic keys, aggregate signatures, and commit cross-chain state

Business Value Proposition​

  • Scalable Signature Aggregation: supports both simple verification (optimal for ≤125 validators) and ZK-proof verification (for larger validator sets with constant gas costs)
  • Modular Architecture: extensible system with pre-built modules for operator whitelisting, blacklisting, jailing, multi-token support, and automated vault deployment
  • Enterprise Integration: built on proven cryptographic foundations with support for both BLS-BN254 and ECDSA-secp256k1 key types

Core Capabilities​

  • Dynamic Validator Set Management: automatically derive and maintain validator sets based on operator stake and voting power
  • Cross-Chain State Commitment: maintain compressed validator set headers across multiple chains
  • Flexible Onboarding Schemes: support various operator registration patterns through modular extensions
  • Cryptographic Verification: verify aggregated signatures with both direct and zero-knowledge proof mechanisms
