How Walrus compares
Frequently asked questions
What does Walrus do?+
Walrus is a data platform that keeps data portable, protected and verifiable across systems. It stores critical records persistently and supports agents, applications and marketplaces. Control and verification stay central to how it operates.
How does Walrus prove data remains unchanged?+
Walrus creates a unique ID from the contents of stored data and records that ID externally. Anyone can compare stored bytes against the ID to confirm no alteration occurred. Storage nodes also post proofs that they continue to hold the data.
What is Walrus Memory?+
Walrus Memory is the portable memory layer for agents built on the verifiable platform. It stores memory, conversations, checkpoints and reasoning as persistent data across sessions. Authorized applications can read and build on the same shared memory.
Who controls access to data on Walrus?+
