Blockchains are all related through crypto. Crypto means cryptology. Discuss the unifying cryptographic foundations of Blockchain; starting with crypto-primitives like hash functions and signature and encryption schemes to more advanced ideas. How do the DLTs in Hyperledger use these primitives, what is their cryptographic relationship to other popular Blockchains like Bitcoin and Ethereum. Demonstration of these ideas through a demo of explorers on popular chains. This is intended as a beginning to intermediate session.

Beginner
Session Language
English, Chinese if there is a volunteer
Programming Language(s)
We will present snippets in many of these languages from Github repos.
...
Each of these will have demos, of data structures using explorers (of live or testnets as far as they are accessible), of actual code in Hyperledger DLTs
Fabric
- Iroha
- Sawtooth
- Burrow
- Indy
- Quilt
...
- Discuss hash functions
- Symmetric and Asymmetric Cryptography, key exchange (DH as well as other methods)
- Systems View and VulnerabilitiesSignature and Encryption schemes
- Ursa and why reusable libraries are important
- Systems View and Vulnerabilities
- Demo of block structure through unbounded.Advanced topics - ZK, E2EE etc. Grin, ZCash etc.
The Goals
Attendees learn to look at DLTs from a systems perspective , figuring out what unites them and why cryptographic changes in underpinnings cause differences in functional behavior. Why are they the same yet different. Why do we need shared libraries, ursa.
Software to Install Before

According to introductions we had a diverse group of participants from multiple sectors.
Investors, provenance tracking CEOs , data scientists, ethereum developers, students etc.
What worked: A through line linking all blockchains to basic concepts of cryptography.
What needs to be changed: Have the introductions be pointed and limit to 1 minute.
The use of unbounded.hacera.com seems to have worked.
