Corda

What do you like best?

- JVM based, I use existing JMX tools for monitoring, e.g (Prometheus, Graphana)

- All the storage is a relational SQL (Oracle, SQL server, Postrge). Persistence based on ORM (hibernate). Database migrations supported via simple XML files. This is very friendly for Java developers.

- The certificate authority (Doorman) is based on spring boot, very easy to customize for your cert issuance requirements (e.g HSM)

Quick development kick start, unit testing, good documentation, lots of examples

What do you dislike?

- requires JVM 1.8, so it does not work with newer java nor with openjdk

- Corda is a peer to peer network, so when you are implementing message broadcasting use case (one to all) you have to be creative

Recommendations to others considering the product:

easy to use, integration with existing software, devops

What problems are you solving with the product? What benefits have you realized?

Mostly I own you (IOU) type of contracts, digital assets, identity, and document tamper protection problems.

I wrote an app in the past allowing you to select a blockchain platform based on your need.
