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 sealed via Seal (the encryption solution from Walrus) to create a Walrus blob containing immutable proof of delivery.
Why Walrus Storage Matters
Walrus storage provides:
- 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
Impact on Fees
Walrus storage costs are deducted from gross protocol fees before distribution. The minimal cost structure (fraction of a cent per transaction) ensures maximum net fees flow to stakers.
