The client's need was to create a prototype of a bank network system that would verify every transaction between institutions. In addition, each bank was to contain its own nodes and a copy of the blockchain. The client wanted the administration panel (shown on the right), which would show possible transaction inconsistencies and the differences that banks have in their database.

Key tasks:

  • creating the Hyperledger Fabric blockchain architecture
  • implementing chaincodes
  • deploying network to Amazon Managed Blockchain service
  • integrating 'BlockRecon' user interface module with Hyperledger Explorer

The client's need was to tokenize the works of art with assigned numbers. In order to introduce works of art into the blockchain world, the client decided on an auction platform that was to use smart contracts to create ERC-721 (in the future ERC-20) tokens on the Ethereum network and transfer them to winning bidders. The system took a hybrid form (blockchain and server connection) to reduce the costs associated with each auction transaction (customer requirement).
