Announcements

You are invited to a hands-on workshop about Atomic Cross-Ledger Transactions Between Besu & Corda Ledgers using Hyperledger Cacti v2.  Speakers will demonstrate how to create, test and demo an application from scratch using the second major release of the Hyperledger Cacti blockchain interoperability framework.  This is scheduled for Thursday, November 16 starting at 9AM pacific and is a great opportunity to learn more about the latest developments with enabling blockchain interoperability.  If you're interested, register for the workshop.

Hyperledger AnonCreds

Mike Lodder joins the AnonCreds call this Monday, September 25 (7:00 Pacific / 16:00 Central Europe) to discuss the newly accepted Hyperledger Labs project "Agora", a set of repositories that implement the AnonCreds v2.0 specification that we have been discussing, and more.

Date/Time: Monday September 25, 2023, 7:00 Pacific / 16:00 Central Europe

Mike has been working on this implementation for the past several years and we're excited to have the code made open source and available to use and expand upon. The implementation enables the new features that have been envisioned for AnonCreds v2.0, an evolution of the existing AnonCreds specification/implementation that provides:

  1. Flexibility in the underlying signatures, including support for BBS+, PS and CL Signatures.
  2. Expanded Issuer/Holder access to ZKP capabilities, such as set membership, range proofs, verifiable encryption and more.
  3. The familiar participants, interactions, and objects of AnonCreds v1.0, enabling a clear and provend path to adoption

The project also includes a number of other generally useful cryptographic libraries that will be helpful for developers. An example is a key ring library for protecting secrets in memory from side channel attacks like Row hammer and ram bleed. Lots of fun/powerful tools for this space!
