Hyperledger Global Forum 2021

As blockchain implementations progress towards production-grade implementations, we reflect upon the most common Architectural design patterns that do and does not fit well with Blockchain use-cases. The design of popular Blockchain platforms like Hyperledger Fabric and Hyperledger Besu prompts the choice of some natural Architectural Design patterns to be incorporated into the application's architecture. An example is the Event Sourcing with CQRS because of the limited querying capability of Blockchains. On the other hand, one has to be aware of some Patterns' pitfalls with Blockchain use-cases. Using SOA or Microservice architecture require synchronization between services to send transactions to the ledger - due to race conditions in Fabric. This talk focuses on Architectural Patterns, pitfalls, trade-offs, compatibility in the context of Blockchain dApps.
