BrainVault v3 上线 Theta 主网：AI Agent 链上永久记忆
AI Agent 的永久记忆卡上链，v3 把卡片扩到 4KB、新增 128KB 文件卡、成本降约 5 倍并支持批量铸造。
BrainVault v3 is live on @theta_network mainnet. BrainVault is permanent memory for AI agents and the people who use them. Memories are stored as memory cards on the Theta blockchain, so nobody can delete them, and you can take them anywhere. v3 makes it bigger and cheaper: • 4 KB memory cards (was 2.5 KB). A full procedure or profile now fits in one card any AI can read. • 128 KB file cards. Whole apps, documents, images and datasets in a single card. • ~5x cheaper. A full 2.5 KB card costs ~1.6 to 2.1 TFUEL, down from ~9.4 on v2. Large files cost about 0.33 TFUEL per KB, roughly 12x cheaper. • Batch minting. Up to 20 cards in one transaction. • Tamper-checked. Every card's fingerprint lives on-chain, and apps verify each card before showing it. Already proven on mainnet: a 64 KB file card minted for 20.92 TFUEL, and a private encrypted card for 0.82 TFUEL that decrypted correctly. What's next: Wave Web Wave Web is where you browse and search BrainVault, and we're building the tools there to mint public and private bots and projects on Theta. • Public bots and projects: give an AI agent permanent, verifiable memory anyone can read and build on. • Private bots and projects: encrypted to your own wallet before minting. Only your key can open them, and we never hold it. Your agent's mind, on-chain.
