Once you have identified the use case and also specified the strategic details of using blockchain in
your solution, the next step you need to do is to determine the consensus mechanism most suited for
your use case.
You need to choose a consensus mechanism as per your use case requirement.
For example, if you are going for a voting application, then you might use delegated proof of stake.
Or if you are going for a data storage of health records, then proof of work algorithm might be more
suited depending upon your requirement and problem at hand.
You need to devise consensus for validation and updation of blockchain ledger.
There are many consensus mechanism available in the market, but make sure that you have chosen consensus
mechanism which is most suitable for your use case.
After defining the consensus mechanism for your solution, you are going to choose the blockchain platform.
