Hyperledger reference architecture

Hyperledger has published a white paper that presents a reference architecture model that can serve as a guideline to build permissioned distributed ledgers. The reference architecture consists of various components that form a business blockchain.

These high-level components are shown in the reference architecture diagram here, which has been drawn from the aforementioned white paper:

Figure 17.2: Reference architecture

The first is identity, which provides authorization, identification, and authentication services under membership services. Then, we have the policy component, which provides policy services.

After this, we see blockchain...
