Backwards Compatibility provided by Corda
Let's explore some mechanisms through which Corda preserves backwards compatibility.
Corda is a very interesting case study from the perspective of backwards compatibility.
In a distributed system, the various nodes of the system might be running different versions of the software. In many cases, the software is deployed incrementally to them and not in a single step. There is an additional challenge in a decentralized system because different organizations now control the various nodes of the systems so that these discrepancies might last longer.
Corda provides a lot of different mechanisms to preserve backwards compatibility in different areas, so let’s explore some of them.
API & ABI backwards compatibility
Corda provides API & ABI backwards compatibility for all the public APIs available to CorDapps. It means that any CorDapp should run in future versions of the platform without any change or re-compilation.
Similar to other applications, CorDapps are expected to evolve, which might involve:
- Changing the structure of data exchanged between
