🐋 What Walrus Is
Walrus is a decentralized storage network built on the Sui blockchain. It’s designed to let users and developers store large data (like videos, images, AI datasets, websites, NFT media) in a decentralized way — instead of relying on centralized cloud services. �

The network uses a special token called $WAL that powers the system. �

🧠 How It Works: The Basics
🗃️ 1. Upload & Storage
When you upload a file (called a blob), Walrus doesn’t store the whole file in one place.
It uses erasure coding — breaking the file into many tiny shards/slivers and spreading them across lots of storage nodes.
Even if some nodes go offline, the file can still be reassembled. �

This sharding + erasure coding method makes decentralized storage reliable and cheaper than storing full copies everywhere. �

💰 2. The WAL Token: Multi-Purpose
The $WAL token is used for multiple jobs inside the Walrus network:
💸 Payments
Users pay WAL tokens to store or extend storage of data.
Storage fees are paid upfront and distributed over time to node operators and stakers. �

🔒 Staking & Network Security
People holding WAL can stake (lock) tokens to support the network.
Nodes that reliably store and serve data are rewarded with WAL. �

🗳️ Governance
WAL holders can vote on network decisions, like pricing or protocol upgrades. �

🕸️ 3. Technology Behind It
📊 RedStuff Erasure Coding
Walrus uses an algorithm called RedStuff to make storage efficient and fault-tolerant. Instead of full backups, it stores only coded pieces that can rebuild the whole file even if many pieces are lost. �
Superex
📜 On-Chain Metadata
Walrus doesn’t put big files directly on the Sui chain. Instead, it keeps metadata and proofs on-chain, while the actual shards live off-chain with the nodes. This keeps blockchain costs low. �

📦 4. Data Access
When you want your file back, the network reassembles it by fetching shards from different nodes.
Because each node holds only small fragments, retrieval stays fast and efficient. �
