The Sui ecosystem launches an innovative Decentralization storage solution Walrus

After the launch of the computing layer AO by the decentralized storage network Arweave, it successfully drove the return of AR coin price, ecosystem, and popularity. As a general computing chain, the decentralized storage network Walrus launched by Sui has also attracted attention in the industry.

Background Introduction

Team

Walrus is the latest product launched by a well-known blockchain development company, classified as "protocol, platform", and is a Decentralization storage network. Walrus means "walrus", and its official website emphasizes the characteristics of growing robustly and having strong adaptability, highlighting the reliability and availability of this protocol as a storage system.

and the relationship with Sui

Walrus is built on Sui and utilizes Sui to coordinate the sales of storage space and metadata. However, using Walrus does not require building applications or products on Sui. Walrus will launch an independent governance token, WAL, as a utility token.

Competitive Product Comparison

Decentralization storage protocols are generally divided into two main categories:

1. Complete replication system: such as Filecoin and Arweave. The advantage is that there are complete files on the storage nodes, allowing for easy access and migration of files even if a node goes offline. The disadvantage is that the storage overhead is large, and it may be susceptible to Sybil attacks.

2. Reed-Solomon(RS) coding system: It divides files into small chunks for storage. The advantage is high storage efficiency, but the encoding and decoding processes have high computational overhead, which limits the file size and the number of participating nodes.

Challenges Facing Storage

Existing decentralized storage systems face two main challenges:

1. A continuous challenge mechanism is needed to ensure that storage nodes retain data, which affects system scalability.
2. Storage nodes require complex coordination mechanisms, leading many systems to introduce custom blockchains and cryptocurrencies.

Core Innovation

Walrus can quickly and robustly encode data into small shards using innovative erasure coding technology, which are distributed and stored in a node network. Even if a large number of shards are lost, the original data can be quickly reconstructed while maintaining a low replication factor.

Specific innovations include:

1. RedStuff: A brand new 2D coding algorithm designed specifically for Byzantine fault tolerance, based on fountain codes, combining fast operations and high reliability.

2. Asynchronous Storage Proof: First implementation, total replication factor less than 5 times.

3. Efficient Committee Reconfiguration Protocol: Responding to the natural attrition of storage nodes to ensure continuous data availability.

4. Asynchronous Challenge Protocol: Validates the correctness of storage by nodes, with costs expanding logarithmically with the number of stored files.

5. Staking-based economic model: combining reward and punishment mechanisms.

Walrus, centered around the RedStuff protocol, provides a scalable, resilient, and economically viable Decentralization storage solution.

Future Outlook

Walrus will launch an independent token WAL for staking, governance, and more. A testnet is expected to be launched soon, with the mainnet launch date to be determined. Official documentation is currently available to learn how to use Walrus to deploy websites.

With the growing demand for decentralized storage, Walrus, with its innovative technology and close integration with Sui, is expected to occupy an important position in this field.
