Deliverables

1 Requirement understanding & Design
2 Fabric chaincode to accept Aries DIDComm method call from fabric SDK.
3 Invoke chaincode from Aries SDK. Modify Aries SDK to invoke fabric chaincode
4 End-to-End testing

Milestones

Eval 1:

a Writing Chaincode (4 smart contracts in 1 chaincode)
b Calling chaincode from standalone application

Eval 2:

c Standalone application that calls aries/indy which then calls fabric network

Eval 3:

d. Integrating application code in aries/indy which then calls fabric network

Eval 4:

e. Test cases using Fabric
f. Issuance and Verification demo using Fabric

Timeline

Week	Task/Plan	Status
Week	Task/Plan	Status
May 24 - May 28	Analyze and document the plan	Done
May 31 - June 11	Connect with Aries Javascript team and discuss on the initial plan	Done
June 14 - June 25	Write chaincode (1 smart contract for 4 transactions) Code classes for 4 Transactions - Nym, Attrib, Schema, Credential Definition. Write Chaincode that creates and retrieves the 4 transactions. Write Client application that sets up an organization and allows it to interact with the chaincode deployed in fabric network.	Done Done Done Done
June 28 - July 2	Standalone application that calls chaincode inside fabric network Add functionalities to Update and Delete the transaction. Make the payloads similar to what AFJ exchanges with Indy	Done Done Done
July 5 - July 9	Documentation of id and payload that would go inside the fabric network. Eval 1	Done
July 12 - July 23	Design and Code connection to Fabric from AFJ Discussion on design from where connection to Fabric should happen from AFJ Initialize Connection to Fabric from AFJ	Done Done Done
July 26 - August 6	Integrate client application code with AFJ. Code functionality to create / read transaction to / from fabric through AFJ.	Done Done
August 9 - August 13	Test Schema transaction from AFJ to Fabric Network Implement and test creation and retrieval of Schema from fabric as a Ledger	Done Done
August 16 - August 27	Test Nym and Credential definition transaction from AFJ to Fabric Network. Implement and Test creation and retrieval of did and cred def from fabric as a ledger Eval 2	Done Done
August 30 - Sept 3	Write Test cases that supports Fabric as a ledger Write Test Cases That would test functionality of schema, cred def and did doc	Done
Sept 6 - Sept 17	Create a Documentation that has steps for running the demo with Fabric and Indy	Done
Sept 20 - 24
Sept 27 - Oct 1	Eval 3
Oct 4 - Oct 15
Oct 18 - Oct 29	Create a Demo of Issuance and Verification through AFJ and Indy as a Ledger	Done
Nov 1 - Nov 5	Create a Demo of Issuance and Verification through AFJ and Fabric as a Ledger	In progress
Nov 8 - Nov 12	Create a Presentation of the project Eval 4 Final evaluation and presentation of project	In Progress

Methodology

A chaincode was written that would interact with Fabric. It consists of transactions - Nym, Schema, Credential Definition.

A wrapper is written in AFJ that would interact with this chaincode and exercise the necessary transactions.
