only makes the underlying system more efficient but also brings trust and

transparency to the system.

Blockchain can enable the officials to verify the proof of the existence of

documents by comparing the attributes of the provided copy of the document

against the details of the original version stored in the blockchain. Storing the

digital artefacts related to documents in a blockchain makes it secure and

immune to tampering.

SWOC analysis

SWOC includes strengths, weaknesses, opportunities, and challenges.

Strengths

1. Blockchain technology provides decentralized, vigilant, timestamped,

immutable, and consensus-based data storage for the stakeholders.

2. Blockchain technology provides an efficient ledger storage mechanism in

a distributed environment with appropriate authentication and

authorization based on the role of the stakeholder.

3 . Depending on the need of the application domain, either permissioned or

permissionless blockchain environments can be setup.

4. Blockchain-as-a-Service allows for seamless integration for using

blockchain features in various application domains.

Weaknesses

Every technology brings in its own disadvantages, but identification of these

weaknesses early would help in preparation to tackle the problems well before

they affect the developed blockchain ecosystem. Following are some of the

concerns that need to be addressed before deploying blockchain-based

systems:

1. Scalability: The current transaction processing rate of blockchain

platforms varies from 7 transactions per second (tps) to 3 ,5 00 tps

depending on the individual platform’s applicability to a particular

domain, architectural considerations, consensus approach, number of

nodes in deployment, and so on. The generic architectural platforms such

as HyperLedger Fabric, though apparently suitable for requirements of
