...

• Write software according to standardized public specifications
• Development of distributed and decentralized fault tolerant protocols
• Art of writing good documentation, both targeted at developers and at users
• Blockchain/DLT application development: specifically Fabric, Besu, Corda
• Science of blockchain/DLT interoperation

Expected Outcome

• Implement/augment Relay as an SATP gateway, with the ability to run SATP protocol units, communicate SATP messages, maintain logs for audit, and carry out operations in a fault tolerant manner.
  
• Implement and demonstrate end-to-end asset transfer example across two networks running on Fabric, Besu, or Corda.
• Documentation: update Cacti RFC specifications, setup instructions, tutorials.
• (Potentially) Use lessons learned from implementation to update IETF SATP specification draft.
• (Optional) Run performance measurements to benchmark SATP and the Cacti Relay/gateway.

Relation to Hyperledger 

• Core development in Hyperledger Cacti
• Use Hyperledger Fabric and Besu to construct and demonstrate end-to-end example use case.
