Blockchain technology is a digital ledger structure, and this is connected through peer-to-peer nodes and stores transactional records in several databases known as the blockchain. These transactional records are also k/as blocks. Each and every transaction in this ledger is authenticated and can not be tampered with as it is authorized by the digital signature of the owner. Hence this ledger structure of blocks is highly secure and reliable to carry out digital transactions.http://www.techsaga.co.in/
