Hyperledger Sawtooth

Sawtooth is an enterprise-grade distributed ledger that can run in both permissioned and non-permissioned modes. Sawtooth has several new features, which are introduced in the following sections.

Core features

These features include modular design, parallel transaction execution, global state agreement, dynamic consensus, and some other advanced features. We will now explore these features one by one.

Modular design

The modular design of Sawtooth enables separation between the application and the core system. This means that developers can focus on the business objectives instead of worrying about the underlying design of the system. The design of Sawtooth can be viewed as a layered architecture where transaction processors manage the application business logic and, on another layer, validators handle the verification and consensus on transactions. A separate layer called the transaction processing layer is responsible for managing transaction...
