hosting multiple blockchain platforms. This will enable each application to

benefit from the platform-specific strengths. It is also proposed to design and

develop an indigenous blockchain platform incorporating identified best

practices and advanced technological features. On each of these platforms, the

domain-specific chain such as property chain, health chain, education chain,

and so on may be hosted and controlled using the smart contract logic. The

framework would be capable of hosting multiple smart contracts and ledger

meeting the broader requirements of the country. Basic process automation

functional aspects related to assets such as asset creation, linking of an asset to

users, transferring or tracking of asset, and so on, could be provided using

easy-to-use and standard APIs using the National Blockchain API. This will

facilitate in customizing the application software for any workflow

requirements and get the benefits of the National Blockchain infrastructure.

Other generic value addition features, such as proof-of-storage, proof-of-

existence, and predictive visual analytics and intelligence, can be used by any

application to extend its functionality. Predictive visual analytics and

intelligence will help to build business intelligence from the metadata of

blockchain. The applications can also have integration points with existing

national services such as e-Pramaan, Aadhaar, e-Sign, Digilocker, and so on.

Security and privacy aspects can be enabled across the layers of the blockchain

framework.

Integration of important National Level Services to blockchain

e-Sign

e-Sign is a Public Key Infrastructure (PKI) based online service. This

service helps the citizens in the instant signing of their documents, enabling

non-repudiation in a legally acceptable form. e-Sign service is being leveraged

in various applications by Government and private agencies.

ePramaan

ePramaan is a standards-based e-Authentication framework. It provides

Security Assertion Markup Language (SAML) based single sign-on, which

can seamlessly get integrated with state and national level applications. This

makes it ideal for facilitating single window authenticated access to different

government services and applications.
