Google Cloud and Sui Build a Proof Layer for AI Agent Actions

On Tuesday, the Sui Foundation announced on X that Mysten Labs has partnered with Google Cloud to launch Verifiable Agent Arbiter (VAA), an evidence layer enabling enterprises to prove their AI agents acted as authorised, using Sui Network and Walrus Protocol as anchors. 

As agents execute transactions and act across company boundaries, standard logs are not enough. Counterparties, auditors, and regulators demand proof of their integrity.

VAA delivers that proof and helps enterprises meet upcoming regulations, including the EU AI Act. VAA enables powerful enterprise capabilities: 

  • Dispute replay for companies transacting via the Agent2Agent (A2A) protocol 

  • Incident reconstruction for security teams 

  • Verifiable agentic commerce via Sui Agent Payments and x402

Sui is a Layer 1 blockchain designed to provide top-notch developer and user experiences backed by robust technological foundations. It is a groundbreaking layer-1 blockchain platform designed to support the needs of global adoption by offering a secure, powerful, and scalable development platform. At its core, Sui leverages a novel object-centric data model and the secure Move programming language to address inefficiencies prevalent in existing blockchain architectures.

On top of strong technical foundations, Sui prioritizes user experience by eliminating barriers commonly associated with blockchain interactions. Through innovations like zkLogin, sponsored transactions, and programmable transaction blocks, Sui creates a higher standard for user experience within Web3 by ensuring applications are accessible and user-friendly. 

Sui’s innovative architecture offers low-latency transactions with stable transaction fees, high throughput through horizontal scaling and parallelized execution, and empowers developers with powerful capabilities and tools to craft the next generation of Web3 applications.

At the heart of Sui's uniqueness lies its object-oriented design, offering a new way of developing on blockchain. Offering powerful capabilities in a way that ensures deep composability with important developer and user safety measures. As everything on Sui is an object, the ability to define object types allows developers to create objects tailored to their application needs with inherent network-wide compatibility. This changes how assets and protocols can work together to create greater products with broad composability.

SUI is down 4.3% in the last 24 hours, trading at $1.13 per coin.
