About Blockchain technology

  • A blockchain is a specific type of data structure which can be used to transact across nodes or participants.
  • The ownership rights are recorded in cryptographically stored and linked blocks which contain records of ownership of assets among the participants that can remain anonymous.
  • Blockchains are open, distributed ledger that can chronologically record transactions between two or more parties efficiently in near real time.
  • The prerequisite for each subsequent transaction to be added to the ledger is the respective consensus of the network participants (called nodes), thereby creating a continuous mechanism of control regarding manipulation, errors, and data quality.
  • The blockchain technology generally has key characteristics of decentralization, persistency, anonymity and auditability. With these traits, blockchain can greatly save the cost and improve the efficiency.
  • It has various applications like in field of banking, capital markets, cybers security, healthcare, agriculture, telecom, governance etc.
  • The NITI Aayog is exploring the use of blockchain and AI technologies in diverse areas such as education, healthcare, agriculture, electricity distribution and land records, among others.
