Explanation: 

Detailed explanation-1: -A blockchain platform is a shared digital ledger that allows users to record transactions and share information securely, tamper-resistant. A distributed network of computers maintains the register, and each transaction is verified by consensus among the network participants.

Detailed explanation-2: -A blockchain is a decentralized ledger of all transactions across a peer-to-peer network.

Detailed explanation-3: -A blockchain can be either centralized or decentralized. It is important, however, that decentralized not be confused with distributed. While a blockchain is inherently distributed (meaning that many parties hold copies of the ledger), it is not inherently decentralized.

Detailed explanation-4: -Correct Option 2). A blockchain is a digitally distributed, decentralized, public ledger that exists across a network. A blockchain is a distributed database that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format.

Detailed explanation-5: -A blockchain is a type of distributed database or ledger-one of today’s top tech trends-which means the power to update a blockchain is distributed between the nodes, or participants, of a public or private computer network. This is known as distributed ledger technology, or DLT.
