Architecture

This article describes the architecture of the confidential computing platform that underlies both Confidential Computing Ledger workloads: Azure confidential ledger and Microsoft's Signing Transparency Ledger.

The platform is a REST API service that lets clients interact with the ledger through administrative and functional API calls. When data is recorded to the ledger, it's sent to permissioned blockchain nodes that are replicas backed by hardware-based secure enclaves. The replicas follow a consensus protocol. Clients can also retrieve receipts for data that was committed to the ledger.
