Decentralized Validation Network
The Decentralized Validation Network is responsible for monitoring trades and ensuring that the Optimex Vault settles assets correctly when all trade conditions are met. It consists of Multiparty Computation (MPC) nodes, which collectively authorize transactions using a threshold signature scheme.
Structure & Security
MPC Nodes: The Validation Network initially consists of three MPC nodes, producing a 2-of-3 threshold (tECDSA) signature for trade settlement.
Epoch-Based Key Refresh: To enhance security, MPC nodes and their cryptographic keys are refreshed at regular epochs.
Security Deposits & Slashing:
Each node must stake a security deposit, ensuring economic accountability.
Nodes are slashed if they deviate from protocol rules, such as failing to sign in time or blocking valid settlements.
The combined stake of all nodes must always be greater than the value of assets temporarily controlled by the Vault during trades.
Scalability & Risk Mitigation:
Because assets remain under Vault control only during the trade process and are settled immediately, the Validation Network can facilitate billions in trading volume with reasonable security deposits (e.g., $10M–$20M per node).
The Validation Network's decentralized design ensures trustless trade execution, high security, and economic alignment among participants in the Optimex ecosystem.
Current Deployment
The Validation Network currently comprises three nodes operated by three independent teams:
This multi-party setup ensures no single entity controls the committee, providing decentralization from day one while the network scales toward broader validator participation through permissionless staking.
