๐ฏ DAL Applications and Use Cases
๐ DAL vs L1 Comparison
| Metric | L1 | DAL |
|---|---|---|
| Bandwidth | ~32 KB/s | 0.5-100 MB/s |
| Cost | High | Low |
| Decentralization | Full โ | Full โ |
| Best For | Consensus | Large data |
๐ก Tezos X Roadmap
DAL is critical for:
- Scaling to millions of users
- Competitive L2 ecosystem
- Future: 100 MB/s target
Primary use today: Smart Rollups (like Etherlink) posting L2 operations โ this is what fills the DAL slots you're attesting and earning rewards for!
Primary Applications
1๏ธโฃ Smart Rollups Primary Use
Purpose: Publish Layer 2 operations and state data
Why: 1,500x+ increase in data throughput!
Examples: Etherlink (EVM rollup), Gaming rollups, DeFi applications, High-throughput L2
2๏ธโฃ dApps & Smart Contracts
Purpose: Store large data blobs cheaply
Use Cases: NFT metadata (images, videos), Large contract state, Off-chain data references, Application data storage
3๏ธโฃ Rollup Operators
Purpose: Post rollup transaction batches
Benefits: Reduced fees vs L1, More transactions per batch, Higher throughput
4๏ธโฃ Data Availability Services
Purpose: Decentralized storage verification
Use Cases: Decentralized file storage, Data markets, Archival services, Censorship-resistant data

Current Faculty
Four distinguished faculty members maintain the institutional legacy from our founding in 1847, bridging centuries of cryptographic innovation.
๐ Prof. Hans von Schlรผsselstein
Heidelberg-trained specialist in key distribution and threshold cryptography. Known for rigorous teaching in secure delegation theory.
โ๏ธ Prof. Niccolรฒ Testamonte
Florentine legal scholar exploring moral dimensions of digital trust. Coined "A chain of eyes is stronger than a seal of wax."
โ๏ธ Prof. Severin Kettenbuch
Viennese creator of chained record books. His prophetic lectures on distributed continuity blur history and future.
๐๏ธ Dr. Erasmus Signet
English semiotician and former royal notary. Established the systematic study of seals, marks, and institutional authority.
