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.

There are three Discord channels:
- #sawtooth - general discussion / Q&A
- #sawtooth-contributors - contributor discussion
- #sawtooth-announcements - official announcements
There is a sawtooth mailing list but the most active discussions are on Discord.
Release Notes: Release notes will be provided for release 1.0 and thereafter.
The project will follow the Hyperledger security bug process and identify any security vulnerabilities fixed in the release.
Security bugs: Security bugs can be reported to email@example.com.
The Sawtooth project will follow the HyperLedger security process and will respond within 14 days.
Static analysis: The Sawtooth project will follow the Hyperledger security process and address bugs found by static analysis in a timely manner.
Dynamic analysis: The Sawtooth project will perform dynamic analysis prior to major releases will follow the Hyperledger security process and address bugs found by static analysis in a timely manner.
