Ethereum Mainnet: A Decentralized Platform for Smart Contracts

The Ethereum Mainnet is a decentralized platform that enables the creation and execution of smart contracts. It was launched on July 30, 2015, by Vitalik Buterin and the core Ethereum team.

The mainnet uses a Proof of Stake consensus mechanism, which replaced the old energy-intensive Proof of Work model in September 2022. Validators are chosen to propose and confirm new blocks of transactions, earning rewards paid in ETH in exchange for securing the network.

Every operation on the mainnet requires a fee called gas, measured in gwei. Gas fees fluctuate based on network demand, making it essential for users to understand how the system works.
