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.

Note to Developers

  • 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.
