Aegis - Validator Set Configuration

EO Validator Sets are integrated into the Ethereum PoS Validator Set through the Aegis protocol, enabling Ethereum validators to participate freely in the EO network permissionlessly.

Validator Set Membership

EO is an expansion chain that derives its cryptoeconomic security from Ethereum staking and benefits from the stability of ETH. Through innovative infrastructure provided by Eigenlayer, Ethereum Validators are able to participate in the EO blockchain as part of Validator Set. Validators can initiate a withdrawal from the Validator Set, and membership can be revoked for misbehavior, within Ethereum.

Naively implementing a new PoS protocol is not possible since the validators' stake is managed on Ethereum rather than directly by the protocol. To address this challenge, we developed Aegis—a novel protocol for creating an expansion chain based on primary-chain stake, in our case, restaked ETH. The EO blockchain is built on Aegis.

Aegis uses references from Aegis blocks to primary-chain blocks to define Validator Set, checkpoints on the primary chain to perpetuate decisions, and resets on the primary chain to establish a new committee if the previous one becomes obsolete. It ensures safety at all times and rapid progress when latency among Aegis nodes is low.
