Corda

Architecture Evolution

The code present in this repository reflects the first version of the implementation of the Corda model for DLT technology. This first architecture version covers Corda versions 1 through 4 and continues to deliver on the promise of DLT for both the open source community and industry as a whole.

However, like all things, Corda must evolve to serve the more stringent needs of today. This is why the second (and current) version of the Corda Architecture can be found here and will form the basis of the Corda 5 release.
