The rapid pace of innovation in the development and deployment of blockchain technologies is creating more points of intersection for cross chain and cross application data and transaction flow. Fortunately, there is also a robust effort underway to deliver new approaches to ensuring that solutions work across platforms and protocols. Case in point: at the upcoming Hyperledger Global Forum, there will be 20 talks covering various aspects of blockchain interoperability and integration.
Below, we take a look at a sampling of use cases where Hyperledger technologies are at play in solutions that are operating in or enabling cross-platform production deployments:
Daml
Daml, a multi-party application platform created by Digital Asset, is widely used in distributed applications that deliver portability across a number of blockchain platforms, including Hyperledger frameworks: Besu, Fabric and Sawtooth. Recently, using Hyperledger Fabric, Ethereum and a traditional Postgres database, Digital Asset demonstrated platform interoperability and open sourced the code to help CBDCs (and other applications that need to integrate with CBDCs) interoperate, making the digital currencies compatible regardless of the underlying technology. The code for this CBDC use case is available on Git Hub. Read more and watch the demo here.
Hala System’s Sentry
Hala Systems is using Hyperledger Fabric alongside Hedera as part of its Sentry early warning system, which helps protect 2M+ people in Syria. Hala Systems uses both Hyperledger Fabric and Hedera to manage the metadata of created media and user input produced in conflict. The hashed metadata is simultaneously written to a private blockchain built on an IBM Blockchain Platform powered by Hyperledger Fabric and to Hedera Consensus Service. Hala Systems uses the IBM Blockchain Platform to act as its internal repository, preserving additional metadata to augment the auditable hash data sent to Hedera Consensus Service. With these two sets of records, any third party can verify the information on the public ledger to match the image and, if necessary, its accompanying data stored on the private ledger.
Project Starling
Project Starling was developed to help empower organizations to securely capture, store, and verify human history. Starling represents a ground-breaking methodology in the fight against the spread of misinformation and the looming threat of deep fakes by providing open-source tools. Starling uses the latest cryptographic methods and decentralized web protocols to meet the challenges of establishing trust in our most sensitive digital records.
Jointly developed by teams at USC and Stanford, the Starling framework leverages multiple decentralized technologies including IPFS, GUN, Hyperledger Fabric, and Hedera Hashgraph throughout its process. For each piece of media captured, the framework is designed to store images on IPFS, using Filecoin, these image’s associated metadata is then stored in a permissioned Hyperledger Fabric network, securely protecting any sensitive information. For each media file, a hash of the information stored in Hyperledger Fabric is taken and recorded on the public Hedera network. By doing so, third parties are able to more readily trust the application owner and be assured no bad actor has falsified or modified results after the fact.
