There’s no doubt that @Arbitrum is becoming the hub for on-chain AI.

This all comes together through ERC-8004, which acts as the backbone for how agents show who they are, and whether they can be trusted. ERC-8004 focuses on three registries: identity, reputation, and validation. -------------------------------------------------- 𝐇𝐨𝐰 𝐀𝐫𝐛𝐢𝐭𝐫𝐮𝐦 𝐂𝐨𝐦𝐞𝐬 𝐈𝐧 Many AI verification processes require heavy computation, and running them on the standard EVM would be too expensive or simply not possible. This is exactly why Stylus, Arbitrum’s WASM-based virtual machine, matters. It lets developers write contracts in Rust, C++, or similar high-performance languages instead of being locked to Solidity. That means compute-intensive tasks like calculating reputation scores, running trust algorithms, re-executing inference, or validating zkML proofs can now happen directly on-chain without ridiculous gas costs. Stylus transforms what could be a simple proof-anchoring system into a full on-chain execution layer, enabling AI agents to operate autonomously, verifiably, and at scale. This infrastructure addresses one of the biggest challenges in the emerging agent economy: trust. ERC-8004 and Stylus together create an environment where agents can dynamically discover, evaluate, and coordinate with one another in a permissionless, decentralized way.

It’s a basis for applications like agent marketplaces, autonomous DeFi strategies, AI-driven routing, credit networks, fully automated workflows, and agent-to-agent commerce. Imagine wallets that manage themselves, trading strategies that optimize automatically, research agents that collaborate without human oversight, or entire applications that operate as interconnected networks of agents rather than single isolated bots. ------------------------------------------------- 𝐇𝐨𝐰 𝐒𝐭𝐲𝐥𝐮𝐬 𝐈𝐬 𝐒𝐨𝐥𝐯𝐢𝐧𝐠 𝐄𝐑𝐂-8004 𝐂𝐡𝐚𝐥𝐥𝐞𝐧𝐠𝐞𝐬 ERC-8004 still has issues like Sybil attacks, transferable reputations, and privacy concerns, but Stylus makes solving all of this possible. It makes running on-chain solutions economically feasible for the first time. Developers can now implement robust validators, slashing mechanisms, Sybil-resistant scoring systems, encrypted reputation layers, zk-based verification, or even compute-intensive filters similar to EigenTrust.

All of this is happening alongside other Arbitrum initiatives like the x402 payment standard, intent-based architectures, and the growing focus on L2 privacy. In closing, Arbitrum is positioned as the home for a true on-chain agent economy. ERC-8004 gives AI agents identity, reputation, and verifiable work. Stylus provides the compute power and flexibility to make it all practical. Together, they lay a foundation for an ecosystem where autonomous agents can interact, execute tasks with trust and transparency.
