Project:
Hyperledger Sawtooth
In the last quarter focus has been on the Artifact APIs in the Sawtooth Library, contributions to Sawtooth's underlying dependencies (Transact, Augrim), and extending the Go SDK to include support for consensus engines.
The following work is currently in progress:
- Create a new consensus library that will be used by the Sawtooth validator
- Improve Sabre performance by implementing state caching in Transact for large pieces of state, such as smart contracts.
- Sawtooth 2 component designs
- Migrate to Github Issues, away from JIRA.
- Rewriting the Sawtooth CLI in Rust (paused)

Sawtooth Updates:
- Stabilized SQLite and PostgresSQL support for the ReceiptStore in sawtooth-lib
- Removed smart permission and Pike from Sabre. Pike has been moved to Grid and had a major update, and Smart Permissions are currently not used anywhere but did rely heavily on Pike.
- Community bug fixes

| Description | Distributed ledger with Multi-Language Support |
Originally contributed by Intel, Sawtooth is a blockchain suite designed for versatility and scalability. Distributed Ledger Technology has potential in many fields with use cases from IoT to Financials. This architecture recognizes the diversity of requirements across that spectrum. Sawtooth supports both permissioned and permissionless deployments. It includes a novel consensus algorithm, Proof of Elapsed Time (PoET). PoET targets large distributed validator populations with minimal resource consumption. Transaction business logic is decoupled from the consensus layer into Transaction Families that allow for restricted or unfettered semantics.
Key Characteristics
Pluggable consensus algorithms (Change consensus on the fly by transaction)
Includes Proof of Elapsed Time (PoET) consensus
Write smart contracts in almost any language
Ethereum contract support via Hyperledger Burrow integration
Supply Chain example out of the box
Parallel transaction execution for added throughput
