Hyperledger welcomes Trusted Compute Framework (TCF) project Avalon

The Avalon project started in incubation and is now a full-fledged Hyperledger project

Hyperledger, the open source collaborative effort created to advance cross-industry blockchain technologies, today has announced the latest Hyperledger project called Avalon. It is a ledger independent implementation of the Trusted Compute Specifications from the Enterprise Ethereum Alliance (EEA).

The project is an intersection of Hyperledger, EEA, and cloud service provider ecosystems. According to the Hyperledger team, Avalon “…is perhaps the most broadly sponsored project to date. It brings together sponsorship from Intel, iExec Blockchain Tech, Alibaba Cloud, Baidu, BGI, Chainlink, Consensys, EEA, Espeo, IBM, Kaleido, Microsoft, Banco Santander, WiPro, Oracle, and Monax.”

For blockchain scalability, there has always been a trade-off of resiliency and integrity for performance and confidentiality.

The Trusted Compute Framework (TCF) enables the secure movement of blockchain processing off the main chain to dedicated computing resources. This enables:

TCF is designed to help developers gain the benefits of computational trust and mitigate its drawbacks. A blockchain is used to enforce execution policies and ensure transaction auditability, while associated off-chain trusted compute resources execute transactions.

Preservation of the integrity of execution and the enforcement of confidentiality guarantees come through the use of a Trusted Compute (TC) option, such as:

The approach will work with any Trusted Compute option that guarantees integrity for code and integrity and confidentiality for data. The initial implementation uses a Trusted Execution Environment enabled by Intel Software Guard Extensions (SGX).

The TCF uses a distributed ledger to:

“Now that Avalon has matriculated to a full project at Hyperledger, we are excited to continue maturing and expanding the code base. Some of the initial areas we plan to work on are solidifying the Hyperledger Fabric integration and similarly working with another new addition to Hyperledger, the Ethereum client, Hyperledger Besu.”
