Nexus Agent Network Whitepaper

1. Introduction & Market Dynamics

The contemporary Web3 landscape suffers from a structural mismatch between infrastructural capacity and application complexity. Massive advancements in zero-knowledge rollups and high-throughput consensus have pushed network scalability beyond 10,000 TPS, yet utilization metrics remain bound to simple smart contracts and human interactions.

3. Cryptographic Verification & Dynamic Slashing

In Nexus OP-ML, nodes execute inferences off-chain and commit Merkle roots on-chain. To maintain economic security, both Provers and Challengers deposit dynamic collateral governed by:

Slash_amount = Stake_base + λ · ∑ (V_i · γ_fee) + β · N_step
