Microsoft is launching a preview version of its Azure Confidential Ledger service, its new secure block chain-based ledger.
A few weeks after announcing its intention to close its Azure Block chain as a Service offering, Microsoft is back with a new block chain-based idea with its Azure Confidential Ledger service. Microsoft executives have unveiled the public preview of Azure Confidential Ledger on the first day of its Build 2021 developer virtual conference on May 25.
Azure Confidential Ledger, like Azure Block chain Service, is based on the idea that block chain is a large distributed ledger. Microsoft's Azure Confidential Ledger (ACL) adds an additional layer of security and scalability to the block chain. ACL uses the Azure Confidential Computing Platform, which means that an ACL instance runs in a dedicated, fully verified hardware enclave.
ACL is based on the Confidential Consortium Framework (CCF), which Microsoft officials introduced publicly in 2017. At the time, officials said the Coco Framework (short for "Confidential Consortium") was supposed to work with any distributed registry protocol and run on any operating system and hypervisor that supported a. Compatible Trusted Execution Environment (TEE), or secure area of a processor. The framework was designed for use on-premises and / or in clouds from various vendors, officials said.
Microsoft executives have said that one of the goals of ACL is to meet the needs of users, for example, requiring audit logging and tracking highly sensitive administrative operations. They suggested that healthcare, finance and retail, information technology, supply chain monitoring, and any business where contracts and deeds need to be traded securely would all be good candidates for ACL.
I asked Microsoft if ACL should be considered the replacement for Azure Block chain as a Service and did not get a direct response. Instead, a spokesperson said, “We are asking customers (of Azure Block chain Service) to switch to ConsenSys Block chain Quorum solution. As industry dynamics have changed, we have made the decision to move from a product-oriented offer to a partner-oriented solution. "
