Here's what's known about Cerberus from @Arcium ↓
Cerberus = zero-trust MPC protocol built for privacy under real adversarial conditions.
• Dishonest-majority security (t = n − 1)
Cerberus preserves privacy even if all but one node are malicious. This is the bar institutions care about.
• Malicious security, no trusted dealer
No setup assumptions, no “just trust the coordinator.” Security holds even against active attackers.
• Exact encrypted compute
Uses additive secret sharing → fast local additions + one-round multiplications, no noise growth, no approximation games.
• Economic enforcement baked in
Node operators stake to activate hardware, earn for correct execution, and get slashed for misbehavior. Crypto-native accountability.
• Scaling is being engineered, not hand-waved
Planned integration with @doublezero multicast reduces most communication from O(n²) → O(n), which is critical for real workloads.
• Cheater identification is an active focus
Cheater identification + identifiable abort is being built harden security guarantees.
The thesis is simple but rare:
Privacy without security and correctness is useless.
Cerberus is Arcium’s attempt to make encrypted compute correct by construction, even when the environment is hostile.
Bullish on @Arcium.
