The Ethereum Foundation has announced a new solution that will cut deposit times from Ethereum Layer 1 to Layer 2 networks and exchanges to just 13 seconds. The new Fast Confirmation Rule (FCR) is expected to reduce wait times by 80-98% for most users. FCR achieves this speed by counting attestations rather than blocks to confirm deposits. The foundation stated that the solution minimizes the risk of reorgs under reasonable assumptions, such as network synchronicity and a 25% stake limit, and includes a fallback mechanism that waits for full finality if these conditions are not met, ensuring security. The FCR solution is scheduled for implementation within the next few months and will activate automatically on nodes once clients adopt it.

World, the iris-scanning identity project co-founded by Sam Altman, has launched a developer toolkit called AgentKit, CoinDesk reported. The toolkit allows AI agents to carry cryptographic proofs verifying they are operated by a real user via World's World ID system. The launch addresses growing concerns about identity verification as AI agents are increasingly used for online transactions and shopping. AgentKit aims to solve this by linking multiple agents to a single, verified human. The system integrates with x402, a protocol developed by Coinbase and Cloudflare. The x402 protocol enables agent-to-agent payments by applying stablecoin micropayments to the internet's communication layer, allowing AI agents and software to transact without human intervention. By implementing x402, World aims to establish AI agents as verifiable economic participants rather than just suspicious automated traffic.
