Why ArcNano Is So Much More Private & How Our Groth16 Proof Generates
Understanding why traditional Web3 payments leak sensitive agent intelligence, and inspecting the mathematical zero-knowledge proof mechanics inside spend.circom.
The Public Explorer Surveillance Trap (msg.sender)
In standard public crypto payments, every micro-query to an LLM or data provider creates an on-chain transaction. Anyone watching the Arc block explorer sees msg.sender paying the AI provider, permanently linking proprietary prompt traffic and counterparties to your wallet.
The Naive Zero-Knowledge Trap
Beginners often assume “I'll just use a ZK proof to hide the payment.” But if your wallet signs the EVM transaction calling contract.spend(proof), your address is broadcast in the transaction envelope, instantly destroying anonymity.

Legacy mixers (like Tornado Cash) pool clean and illicit funds indistinguishably, leading to global regulatory bans and blacklisting by legitimate APIs that cannot risk accepting dirty money.
The 3-Second Latency Gap
Even with Arc's rapid 3-second block finality, 3,000ms is an eternity for an AI streaming tokens at 60 tokens/second (1 token every ~15ms). Chaining 5 tool calls adds 15s of pure blockchain stall.
< 8ms off-chain, tokens stream instantly, and settlement happens asynchronously.
