Sui launches the Decentralization storage network Walrus, introducing an innovative Algorithm.

The decentralized storage sector is welcoming new competitors. With Arweave launching its computing layer AO and achieving success, Sui has also introduced its own decentralized storage network Walrus as a general-purpose computing chain, bringing new solutions to this field.

Walrus is the latest product launched by Mysten Labs, classified as "protocol, platform". The project is built on Sui, utilizing Sui to coordinate the sale of storage space and metadata. It is noteworthy that using Walrus does not require building applications or products on Sui, and Walrus will launch a standalone governance token WAL.

In the field of decentralized storage, existing solutions are mainly divided into two categories: fully replicated systems and systems using Reed-Solomon coding. These systems have their own advantages and disadvantages, but all face challenges such as storage efficiency, scalability, and node coordination.

The core innovation of Walrus lies in its use of the RedStuff encoding algorithm. This is a new type of 2D encoding algorithm specifically designed for Byzantine fault tolerance, combining the advantages of fountain codes. RedStuff encodes data into primary slices and secondary slices, distributed across storage nodes, through simple XOR operations. This method maintains a low replication factor (4-5 times) while still ensuring high data availability and fault tolerance.

Compared to existing solutions, Walrus's RedStuff Algorithm has faster encoding/decoding speeds, lower storage overhead, and can scale to hundreds of nodes. In addition, Walrus also introduces an efficient committee reconfiguration protocol and an asynchronous challenge protocol, further enhancing the system's reliability and efficiency.

The economic model of Walrus is based on staking, combined with reward and penalty mechanisms. Its innovative storage certification mechanism expands logarithmically with the number of stored files, effectively reducing the cost of proving file storage.

Overall, Walrus, centered around the RedStuff protocol, provides a scalable, resilient, and economically viable Decentralization storage solution. This is all thanks to Sui as its control layer, offering scalable, programmable, and secure infrastructure.

Walrus is expected to launch its testnet soon, with the mainnet launch date to be determined. Currently, interested developers can refer to the official documentation to learn how to use Walrus to deploy their own websites. As the project progresses, we will see whether Walrus can create a new wave in the field of Decentralization storage.
