When I first looked into Walrus, I realized it was solving a quiet but serious problem in crypto. Blockchains are good at moving value and running logic, but they struggle with large data. Walrus is designed to handle that missing piece.
The system works by taking a file and breaking it into many fragments using erasure coding. These fragments are spread across independent storage nodes. No single node holds the full file, but the network can always rebuild it as long as enough fragments are available. This design improves resilience and keeps costs lower than simple replication.
Walrus is closely integrated with the Sui blockchain. Sui acts as the coordinator, keeping records of stored data, verifying availability, and managing payments. The actual data stays off chain, which keeps the blockchain efficient while still allowing apps to reference stored files.
WAL tokens are used throughout the system. Users pay in WAL to store data, and node operators stake WAL to participate and earn rewards for reliable service. They’re incentivized to stay online and honest.
