BAC-L3-TIA-116Celestia and modular blockchains
The economics of data availability
For a rollup, data publication is the dominant cost line. Controlling it is an architecture skill, not a late optimisation.

Learning objectives
- 01Break down a rollup's publication cost
- 02Reduce that cost through compression and batching
- 03Build a three-year cost model
Guided lab
Measure your rollup's publication cost, then cut it through compression and batching.
Independent lab
Model the annual cost of a rollup serving a million traceability transactions.
Security angle
Over-compression can make data unrecoverable without proprietary tooling: availability includes readability.
Assessment
Cost model with a measured before/after reduction.
