🧵Lighthouse February 2026 Update Summary: Lighthouse released SDK v0.4.4, adding support for CAR file uploads to IPFS/IPLD DAGs. This update also covers persistent storage for AI agent memory, USDC-based x402 pay-as-you-go uploads, and Turby tokens. 1/ Agent Memory @LighthouseWeb3 shared its February update, focusing on persistent storage for AI systems. Many agents rely on ephemeral memory layers and centralized services that reset data. Lighthouse proposes an encrypted storage scheme that allows agents to retain data, records, and historical information. 2/ SDK Update SDK v0.4.4 adds support for CAR files. Developers can upload complete content-addressed DAGs without unpacking or dataset processing. This version supports IPFS and IPLD workflows used in AI data pipelines and includes upload progress tracking. 3/ Storage Model Lighthouse discussed the limitations of vector memory and temporary contexts used in many AI systems. At the heart of the proposal is persistent storage, which keeps agent data secure while performing different tasks, ensuring encryption and user ownership of stored information. 4/ Payments @Filecoin mentioned Lighthouse's work on x402 uploads. After a request returns a 402 response, the client pays with USDC using the base currency, then retryes with the transaction hash and receives the CID. Lighthouse also enabled the Turbo Mint.
