* CORDA-696: Ensure deterministic transaction id calculation for contract upgrade and notary change transactions. The problem with the previous implementation is that the transaction would be deserialized with the schema specified in the serialized form, but the calculation of the id would involve re-serializing properties using a local serialization context which might produce a different result. * Support forwards compatibility for new hidden or visible properties * Some refactoring and updating api docs * Fix tests & add custom serializer in case the transaction is captured in a checkpoint * Update id calculation for notary change transactions as well - no filtering is involved * Use computeNonce * More refactoring * Use helper for computing component hashes * Optimise id calculation
Corda
Corda is a decentralised database system in which nodes trust each other as little as possible.
Features
- Smart contracts that can be written in Java and other JVM languages
- Flow framework to manage communication and negotiation between participants
- Peer-to-peer network of nodes
- "Notary" infrastructure to validate uniqueness and sequencing of transactions without global broadcast
- Enables the development and deployment of distributed apps called CorDapps
- Written in Kotlin, targeting the JVM
Getting started
- Read the Getting Started documentation
- Run the Example CorDapp
- Read about Corda's Key Concepts
- Follow the Hello, World! tutorial
