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.  

...

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

...

  1. Discuss hash functions 
  2. Symmetric and Asymmetric Cryptography, key exchange (DH as well as other methods) 
  3. Systems View and VulnerabilitiesSignature and Encryption schemes
  4. Ursa and why reusable libraries are important
  5. Systems View and Vulnerabilities
  6. 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 underpinnings cause differences in functional behavior.
