The production Walrus Mainnet is now live, and operated by a decentralized network of over 100 storage nodes. Epoch 1 begun on March 25, 2025. The network can now be used to publish and retrieve blobs, upload and browse Walrus Sites, as well as stake and unstake to determine future committees using the live Mainnet WAL token. On Mainnet, the Walrus security properties hold. And Walrus is now ready to satisfy the needs of real applications.
We are today redeploying the Walrus Testnet to incorporate various improvements, including some backwards-incompatible changes. Make sure to get the latest binary and configuration as described in the setup section.
Walrus is an innovative decentralized storage network for blockchain apps and autonomous agents. The Walrus storage system is being released today as a developer preview for Sui builders in order to gather feedback. We expect a broad rollout to other web3 communities very soon!
Today, a community of operators launches the first public Walrus Testnet. This is an important milestone in validating the operation of Walrus as a decentralized blob store, by operating it on a set of independent storage nodes, that change over time through a delegated proof of stake mechanism. The Testnet also brings functionality updates relating to governance, epochs, and blob deletion.
In June, Mysten Labs announced Walrus, a new decentralized secure blob store design, and introduced a developer preview that currently stores over 12TiB of data. Breaking the Ice gathered over 200 developers to build apps leveraging decentralized storage.
We have redeployed the Walrus Devnet to incorporate various improvements to the Walrus storage nodes and clients. In this process, all blobs stored on Walrus were wiped. Note that this may happen again on Devnet and Testnet, but obviously not on the future Mainnet.
