Why Blockchain?

  • Secure

It is impossible for anyone to temper with transactions or ledger records present in blockchain

  • Worldwide Adaptation

Blockchain has been adopted worldwide and has the backing of many investors form banking and non-banking sector

  • Automated Operations

In blockchain operation are fully automated through software. Private companies are not needed to handle operations

  • Open

Blockchain is a open source technology. All operations in blockchain are carried out by the open source community

  • Distributed Architecture

Blockchain works in a distributed mode in which records are stored in all nodes in the network. If one node goes down, it doesn’t impact the other nodes or records

  • Flexible

Blockchain is programmable, using basic programming concepts this make blockchain flexible.
Learn about blockchain from the Intellipaat Blockchain Training Course and excel in your career as a blockchain specialist.

Learn what blockchain can do

Blockchain is a digital ledger that keeps a record of all transactions taking place on a peer-to-peer network. All information transferred via blockchain is encrypted and every occurrence recorded, meaning it cannot be altered. It is de-centralised, so there’s no need for any central, certifying authority. It can be used for much more than the transfer of currency; contracts, records and other kinds of data can be shared. Encrypted information can be shared across multiple providers without risk of a privacy breach.

  • Distributed ledger on the internet
  • Each action is & stays visible for everyone; only adding lines is possible
  • “Peer to peer”: no third party is required in order to carry out transactions
  • Secured by uncrackable cryptography
  • Useful for everything having value in the broadest sense
