If this database requires millions of dollars to secure lightweight financial transactions, then there’s a chance blockchains are the solution.

Is the speed of the transaction the most important consideration?
Does this database require high-performance millisecond transactions?

If high performance, millisecond transactions are what is required, then it’s best to stick with a traditional-model centralized system.

Centralized data systems based on the client-server model are faster and less expensive… for now.
