๐ŸŽฏ DAL Applications and Use Cases

๐Ÿ“Š DAL vs L1 Comparison

Metric L1 DAL
Bandwidth ~32 KB/s 0.5-100 MB/s
Cost High Low
Decentralization Full โœ… Full โœ…
Best For Consensus Large data

๐Ÿ’ก 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๏ธโƒฃ 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๏ธโƒฃ 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๏ธโƒฃ Rollup Operators

Purpose: Post rollup transaction batches

Benefits: Reduced fees vs L1, More transactions per batch, Higher throughput

4๏ธโƒฃ 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.

๐Ÿ”‘ Prof. Hans von Schlรผsselstein

Heidelberg-trained specialist in key distribution and threshold cryptography. Known for rigorous teaching in secure delegation theory.

โš–๏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.

๐Ÿ›๏ธ Dr. Erasmus Signet

English semiotician and former royal notary. Established the systematic study of seals, marks, and institutional authority.
