🇺🇸 29,700 new US businesses are projected to form monthly over the next year. Many will run on agents from day one. Their records will need to be provable, not just kept. That's where Walrus, a verifiable data platform, comes in.
📣 Great conversation with @inkray_io about the future of decentralized publishing. Built on Walrus, Inkray gives creators decentralized storage for their content while making it easy to bring existing work on-chain, including automatic imports from Medium via RSS. Community feedback will help sha
Scale past one agent and most teams hit the same three memory problems. → Context disappears when a session ends → Agents overwrite each other's state → No audit trail when something breaks Walrus Memory was built for all three. 🦭
One person running 40 agents is the new normal. But can their agents share what they know and build on eachother’s work? Walrus Memory provides them with one source of truth, making them production-ready and more efficient.
Many AI teams treat memory and context as the same thing. They aren't. Context is what the model sees right now. Memory is what survives after the session ends. That distinction doesn't matter in a demo. It matters when an agent needs to pick up where it left off. That's where Walrus Memory fits:
Most memory systems were built for a single agent, but the future of AI is teams of agents working together. Once multiple agents enter the loop, memory stops being personal and becomes collective: shared state that lets agents coordinate and build on what the team has learned. Walrus Memory gives
.@Cole_Medin used a single prompt to set up Walrus Memory across Claude Code, Codex and Pi, and it stays encrypted and owned by him the whole way. Watch the demo 🦭👇
Yesterday's X Space covered a lot of ground on Walrus Memory. 🦭 - Memory that's portable across apps, sessions, and models, verifiable, and programmable so you control access - 38K memories registered in the first two weeks, ~2K agent owners, around 7% daily growth - The Fable moment as proof of t
