Hyperledger Global Forum

Hyperledger and the Confidential Compute Consortium are two Linux Foundation projects providing unique enterprise computing models. At the intersection of these two projects is Avalon. Avalon makes the trusted execution capabilities of CCC usable in the distributed ledger frameworks provided by Hyperledger. Beyond deployment in HL frameworks Avalon also provides ease of composition in other B2B and distributed applications.

In this talk we will discuss how these open source efforts intersect and some of the impacts of that intersection emerging in cloud service provider capabilities. Technology leaders will benefit from learning about Avalon’s building blocks and lessons learned from some of the first commercial adoptions. Developers will learn about the application design model and cloud friendly container patterns for rapid prototyping. We will tie these topics and audiences together by walking through at least one end to end usage. This usage will demonstrate how to process confidential information between parties both attached to and disconnected from Fabric and Besu networks.

Additional presenters include:

• Manjunath A C
• Tong Li
• Joshua Satten
• Jim Zhang

Avalon addresses blockchain scalability and privacy challenges by moving compute intensive and private data processing off-chain. Other similar approaches typically trade resilience and integrity for scalability and privacy. Avalon avoids this trade off by utilizing trusted compute options, ZKP, MPC, and hardware based Trusted Execution Environments (TEE) to ensure that off-chain computation was done correctly and securely. Common usages include integration of existing legacy applications with blockchains and utilizing external data sources in decentralized applications (aka attested oracles).

During this workshop you will:
• Understand Avalon architecture and how it extends a notion of computational trust (when computer processing is used to establish validity of transactions rather than an institution or intermediary) beyond blockchain
• Learn what does it take to create and integrate a new worker type to Avalon, e.g.worker compliant with Confidential Compute Consortium requirements
• Implement a trusted workload for execution within Intel SGX trusted execution environment
• Apply Avalon framework to develop an attested oracle by accessing an external data source from the trusted workload
• Utilize Avalon to build end-to-end applications that bring trusted off-chain capabilities to Hyperledger Besu and Fabric blockchain networks
