This repository implements and benchmarks Block-STM and other baselines for the paper Block-STM: Scaling Blockchain Execution by Turning Ordering Curse to a Performance Blessing. The implementation of Block-STM has been merged on the main branch of the Diem blockchain open source code-base, see PR.

Branches block_stm and aptos implement and benchmark Block-STM with Diem peer-to-peer transactions and Aptos peer-to-peer transactions, respectively. Similarly, branches bohm and litm implement and benchmark Bohm and LiTM with Diem peer-to-peer transactions, respectively.

Note to readers: On December 1, 2020, the Libra Association was renamed to Diem Association. The project repos are in the process of being migrated. All projects will remain available for use here until the migration to a new GitHub Organization is complete.

Diem Core implements a decentralized, programmable database which provides a financial infrastructure that can empower billions of people.

• Diem Core is a prototype.
• The APIs are constantly evolving and designed to demonstrate types of functionality. Expect substantial changes before the release.
• We’ve launched a testnet that is a live demonstration of an early prototype of the Diem Blockchain software.
