After finalizing the blockchain instance, we need to work with APIs which will be used by developers
to make applications interact with the blockchain.
Usually most of the platforms already provide predefined APIs.
If we require to build a blockchain platform from scratch, then we might have to look into the design
and schemas for APIs carefully as per our requirement.
We need to make sure that only those APIs are available which are required for the applications and
there is no leakage of information through our APIs.
Moreover, we can also add permissions or rules over APIs.
Some of the most used APIs that might be required for the blockchain project could be generation of
key pairs, asset issuance, data authentication and so on.
Key generation API will be used by the users to generate private key and addresses, which is valid
for the blockchain asset.
Issuance provides features to generate assets over the blockchain.
Data authentication can be used to verify and authenticate the data.
Reading the blockchain parameters could be used to retrieve information about the blockchain.
Apart from functional APIs, we could also add the APIs to manage addresses over the blockchain.
Like we can add APIs to check, address, balance or check address permissions.
We can also make APIs available for the processes running on top of blockchain like the creation of
smart contracts or interacting with the smart contracts.
We always need to make sure that only those APIs are available for your platform, which are required
by the developers and applications.
We don't need to reveal much of the information to everyone, and we also don't need a solution where
nothing is visible as no APIs are provisioned.
We need to find a balance for APIs on our platform.
After defining the APIs for our blockchain project, we also need to define the front end, which can
be used by administrator and users to interact with our blockchain project.
