Introduction to Encrypted Data Availability & the Private Rollup Stack
Encrypted Data Availability (EDA) is an emerging solution to one of the biggest challenges in modular blockchain design: how to keep transaction data verifiable without exposing sensitive information. Traditional rollups publish transaction data in plaintext to ensure security, but this transparency prevents enterprises, regulated industries, and privacy‑focused applications from adopting them. By encrypting data before it reaches the availability layer, private rollups can achieve confidentiality while maintaining verifiability and scalability. This course explores the technologies, architectures, and real‑world use cases driving this next evolution in blockchain infrastructure.
About the Course
This course provides a complete overview of encrypted data availability and its role in enabling private rollups. It begins with the fundamentals of data availability, explains the cryptographic tools that make encryption possible, and explores how private rollup stacks are built and secured. Learners will study real-world implementations such as Avail’s Enigma upgrade, examine key challenges like key management and interoperability, and understand how these systems are applied across finance, healthcare, identity, and supply chain use cases. By the end of the course, participants will have a clear understanding of both the technical foundations and the practical implications of deploying privacy-preserving rollups.
