ZetaChain functions as a universal Layer 1 blockchain, enabling developers to create applications that function across both blockchain networks and AI models. While it was initially built to address Web3 fragmentation via universal apps, ZetaChain has expanded its interoperability focus to include AI. This is achieved through an AI interoperability stack that facilitates cross-model interactions while maintaining private, user-controlled context. The network offers native connectivity among major blockchain ecosystems and handles global execution, permissions, and settlement for both applications and agents.

The founder of ZetaChain was an early staff member at Coinbase and helped create the Basic Attention Token (BAT). The project’s backers feature leading market makers, prominent exchanges, and early employees from both Coinbase and Binance, specifically Dan Romero, Sam Rosenblum, and John Yi. Also among the investors are key contributors to widely used industry protocols and notable funds, such as JD Kanani from Polygon.

Advisors include Nathalie McGrath, the first Head of People at Coinbase, who grew the exchange’s workforce from 10 to more than 800 people, and Juan Suarez, who acted as in-house counsel for Coinbase between 2013 and 2022.

ZetaChain stands out by merging universal blockchain interoperability with an AI interoperability layer, enabling developers to create a single solution that serves users across various chains and models. The platform features an AI Portal that handles routing and execution among multiple AI model providers, ensuring there is no vendor lock-in. Additionally, it includes a Private Memory Layer that keeps user context encrypted and permissioned while allowing it to remain portable across different applications and models. These elements allow developers to deploy privacy-focused apps and agents with persistent memory, cross-chain capabilities, and global monetization options, all without the need to construct complex backend infrastructure.

ZetaChain operates as a Proof of Stake (PoS) blockchain constructed using the Cosmos SDK and Tendermint consensus mechanism. It enables decentralized, trustless, permissionless, transparent, and efficient connections to external blockchains such as Ethereum, BSC, Solana, Avalanche, Terra, and Bitcoin, as well as layers like Polygon, Optimism, and Arbitrum, without relying on a single point of failure.

The network’s security architecture relies on three components: validators, observers, and signers. Validators produce blocks and earn rewards based on their bonded staking coins. Observers achieve consensus regarding states and events on external chains. Signers manage standard ECDSA/EdDSA keys in a distributed manner to sign messages for ZetaChain. The system employs the GG20 leaderless Threshold Signature Scheme (TSS) for distributed key generation and signing, ensuring that no individual node or person ever holds the complete private key. Every inbound and outbound transaction, along with state-change decisions, is recorded in ZetaChain blocks, making them immutable, verifiable, available, and fully transparent.
