Blockchain technology is a structure that stores transactional records, also known as the block, which consist of several databases, known as the “chain,” in a network connected through peer-to-peer nodes. Typically, this storage is referred to as a ‘digital ledger’.

Every transaction in this ledger is authorized by the digital signature of the owner, which authenticates the transaction and safeguards it from tampering. Hence, the information is highly secured

The amazing part of blockchain is that anyone can read the document but no one can change the data in it.

Ethereum is a blockchain platform with its own cryptocurrency, called Ether(ETH) or Ethererum and its own programming language, called Solidity.

Solidity is an object-oriented, high-level language for implementing smart contracts. Smart contracts are programs which govern the behaviour of accounts within the Ethereum state.

Solidity is a curly-bracket language. It is influenced by C++, Python and JavaScript, and is designed to target the Ethereum Virtual Machine (EVM).
