What demands this conversation? What are the use cases that needs architecture of enterprise applications on Blockchain?

Nigeria Medical Records Use Case Data integrity management service ie notarization to prove the existence or authenticity of a record/document and its status FinTech use cases, i.e. Clearing & Settlement, Syndicated-Loans, Payments An enterprise solution design needs to ensure it can not only scale but also comply with regulatory requirements, offers data protection and abide by data laws such as GDPR.

What are the key criteria consideration one needs to make while designing architecture that includes Blockchain.

It is also important to understand what you are using Blockchain for?

Is it your data store for immutability, data integrity and transparency? Is it your data + logic + network layer i.e. transaction or triggers related implementation? Most importantly don't use Blockchain for the sake of using Blockchain.

How do you decide which Blockchain to use?

who needs to have access to the data? control to the data between all the participants, who owns the ultimate truth? Threat to data integrity? How secure data is? Ability to handle exploding number of transactions without sacrificing security, data integrity, immutability how complex provisioning can be for active and dormant participants?

Security Scalability Immutability and Data Integrity Decentralised/P2P Permissioned/Private

Lessons Learnt

There is no one Blockchain that is able to satisfy all 5 key requirements. Most 'private Blockchain' solutions offers scalability at the expense of immutability and security. Do not treat blockchains as traditional databases. On chain and off chain provides the optimal hybrid solutions that uses blockchain and yet stores most of the information off the chain on private blockchain. You cannot modify an existing record or contract, you can only replace them with a new one.

Lessons Learnt

Because Blockchain is such an evolving “infrastructure”/”technology”, spend time doing proof of concepts, don’t rush into making decisions and publish white papers. Write down key matrix important to you such as hosting cost, transaction speed and ensure it is covered while you build proof of concept. Decision between serverless architecture, or traditional centralised server API architecture that connects with Blockchain downstream.
