Public-Private Blockchain Interoperability
We propose for the first time, a framework for public-private blockchain interoperation - CollabFed. CollabFed is a decentralized gateway architecture that bridges private blockchains with end-users in a public network, enabling secure and verifiable service provisioning for decentralized platforms like e-commerce and cloud federations.
Key Contributions
- Contribution 1: CollabFed ensures multi-party consensus validation and supports secure data transfer between consumers and businesses through interoperability between public and private blockchain networks.
- Contribution 2: The Consensus on Consensus mechanism handles the secure and verifiable transfer of data from the open network into the private blockchain.
- Contribution 3: A novel mechanism based on collective signing (CoSi) generates verifiable results from the consortium, which can be securely accessed by consumers.
- Contribution 4: CollabFed enables collaboration among participating businesses and ensures fair scheduling of requests through distributed consensus, demonstrated through a proof-of-concept implementation using Ethereum, Hyperledger Fabric, and Burrow for cloud federation service provisioning, tested with three emulated CSPs.
