Circle vows zero chain rollbacks on new Arc network
- Circle launched Arc with direct USDC gas fees to simplify institutional compliance.
- Chief Technology Officer Nikhil Chandhok promised Circle will never roll back Arc's ledger after exploits.
- Arc provides sub-second payment finality and micro-credit loops for autonomous AI agents.
Circle refuses to hit the rewind button.
Speaking on Bankless, Circle Chief Technology Officer Nikhil Chandhok detailed the architecture behind Arc, the company's new layer-one blockchain. Arc eliminates volatile native gas tokens, charging network fees directly in USDC. For corporate treasuries holding real-world assets, accounting for native gas tokens on balance sheets has long posed compliance friction. Paying transaction fees in a dollar-pegged stablecoin removes that operational hurdle.
To balance regulatory demands with decentralized development, Arc relies on a permissioned set of validators. Institutional investors require clear identity guarantees from node operators before deploying substantial capital on-chain. Arc pairs these controlled validators with permissionless smart contract execution, allowing external developers to deploy code without Circle's explicit approval.
The strict architecture faces its ultimate test in ledger immutability. Asked how Circle would handle potential exploits from state-sponsored hacker groups like Lazarus, Chandhok declared that the network will never roll back state transitions. Unwinding transactions destroys systemic trust in public digital rails. Even in the event of a multi-million-dollar drain, the ledger stands unchanged.
Beyond corporate treasuries, Circle is positioning Arc as infrastructure for autonomous AI agents. Chandhok argued that current artificial intelligence models operate in isolated silos, trading text rather than verifiable economic output. Arc introduces specialized primitives including reputation scoring, an agent marketplace, and nano-payments capable of processing sub-cent transactions.
These primitives aim to give autonomous software its own native balance sheet. Rather than relying on credit cards tied to human owners, agents on Arc can acquire short-term loans, execute automated trading strategies, and settle interest within seconds. Sub-second finality allows these automated micro-credit loops to operate without traditional seed capital.
Machines do not need bank accounts when they have immutable rails.
