Walrus Blobs

What are Walrus Blobs?

Walrus is Sui's decentralised storage solution that Alkimi uses to store every impression, click, and conversion on-chain. Multiple advertising transactions are bundled up and encrypted via Seal (the data encryption and on-chain access control from Sui) to create a Walrus blob containing immutable proof of delivery.

Why Walrus Storage Matters

Walrus storage provides on chain:

• Cryptographic proof of ad delivery
• Elimination of payment disputes between advertisers and publishers
• Full transparency and auditability

Data Stored in Walrus Blobs

Each blob contains:

• Impression metadata (timestamp, creative details, placement)
• Click verification data
• Conversion tracking information
• Campaign performance metrics
