Web3 introduces a new way of connecting users on the internet that goes beyond the traditional server and client connections. To be part of web3 you have to decide what blockchain you would like to interact with so it begets the question what is a blockchain.

What is a Blockchain

A Blockchain is a decentralized, distributed and typically immutable ledger that is transparent on a public network allowing everyone to view transactions. There are various blockchains, and **Solana **is one of them. We have other examples such as Ethereum, Binance Smart Chain, Polygon and many others.

Think of blockchain as an huge of record of connected users transactions with different pages of this record is saved on the interconnected users instead of it being saved on a server. This is the idea of a blockchain being decentralized and distributed.

Connecting to any blockchain requires users to have wallet addresses and this wallet address can be viewed on the network.
Most blockchain provides a public web interface to view transactions of a wallet. Solana blockchain provides Solana Explorer.
