Comparison and Analysis of AI Agent Infrastructure Protocols @Infinit_Labs, @TalusNetwork, and @wardenprotocol each demonstrate different approaches to the infrastructure for executing and validating AI agents. INFINIT is a real-world AI-based DeFi abstraction layer with over $630 million in total value locked (TVL), where off-chain agents process user intentions and execute on-chain transactions through manual validation. Talus Network is designed as a MoveVM-based layer-1 blockchain that supports AI prediction markets and on-chain agent workflows, providing a deterministic execution environment. Warden Protocol is a modular validation layer based on the Cosmos SDK, which verifies AI computations across various blockchain environments through Statistical Execution Proofs (SPEX). INFINIT operates based on a data stream that combines real-time on-chain and off-chain data, interpreting natural language user inputs to automate complex DeFi tasks. Talus Network utilizes the object-oriented structure of MoveVM to execute agent workflows in parallel, with non-deterministic LLM computations performed off-chain and recorded as signed event results. Warden Protocol allows Solvers to encode intermediate AI computation states as bloom filters, with validators probabilistically sampling these to acknowledge execution with high reliability. Differences in computational efficiency among the three protocols are also evident. INFINIT minimizes gas fees and latency by processing most computations off-chain. Talus Network secures scalability and performance through the parallel execution structure of MoveVM and resource management at the object level. Warden Protocol has lower overhead compared to zero-knowledge proofs or trusted execution environments (TEE), enabling large-scale AI inference verification through probabilistic sampling. In terms of security and transparency, INFINIT has completed external security audits with no serious vulnerabilities reported. Talus Network is open-source and integrates pre-security tools. Warden Protocol also maintains an open-source structure, presenting the official white paper for SPEX and a mathematical threat model. The governance structure sees INFINIT adopting a staking-based structure with IN tokens, Talus Network planning to introduce token governance in the future, and Warden Protocol adopting a fair distribution WARD token without venture capital. Regarding inter-chain integration, INFINIT connects with over 10 networks, including Ethereum, Base, Arbitrum, and Solana, using LayerZero's OFT standard. Talus Network is closely linked to the Sui ecosystem and is pursuing technical integration with the Walrus Protocol. Warden Protocol interoperates with Ethereum, Arbitrum, Polkadot, etc., through IBC, supporting EVM and WASM smart contracts. In terms of ecosystem maturity, INFINIT shows the highest operational completeness. It is integrated with 12 DeFi platforms, with the total TVL of the integrated ecosystem exceeding $600 million. Talus Network enhances its developer-friendly structure through active development and extensive SDK support, while Warden Protocol boasts the largest community size and adopts a community-centric growth strategy. Strategically, INFINIT focuses on user experience and practical DeFi automation, Talus Network concentrates on foundational technologies for building AI-native blockchain applications, and Warden Protocol establishes a trust basis for AI computations centered on the precision and reliability of the validation layer. The three projects each choose different balance points between decentralization, performance, and validation assurance, likely forming a complementary ecosystem.
