How Ethereum Works

Blockchain Fundamentals

At the core of Ethereum's operation lies the revolutionary concept of blockchain technology. A blockchain is a distributed, unchangeable digital ledger that keeps track of all transactions made between computers in a network. In Ethereum's case, this distributed ledger stores a comprehensive history of all transactions and smart contracts executed on the platform. Through this transparent and tamper-proof system, Ethereum ensures trust and security, eliminating the need for intermediaries.

Ethereum's Consensus Mechanism (Proof of Work and Transition to Proof of

Stake)

Ethereum initially operated on a Proof of Work (PoW) consensus mechanism, similar to Bitcoin, where miners competed to solve complex mathematical puzzles to validate transactions and add blocks to the blockchain. However, due to concerns about energy consumption and scalability, Ethereum has been gradually transitioning to a more energy-efficient and scalable consensus mechanism called Proof of Stake (PoS) with Ethereum 2.0. PoS relies on validators who are chosen to create blocks and secure the network based on the number of Ether they "stake" or lock up as collateral. This transition aims to enhance the network's efficiency and sustainability.

Understanding Ether (ETH) as the Native Cryptocurrency

Ether (ETH) is Ethereum's native cryptocurrency and plays a pivotal role in the platform's ecosystem. It serves as a means of value transfer, allowing users to send and receive funds globally in a secure and pseudonymous manner. Beyond serving as digital cash, Ether holds intrinsic value within Ethereum as it is essential for executing smart contracts. These contracts require Ether to cover transaction fees and computational costs, incentivizing miners or validators to process and validate transactions.

Gas and Transaction Fees in Ethereum

In Ethereum, every operation, including smart contract execution and value transfers, requires a specific amount of computational resources. This computational cost is measured in "gas." Users must attach an appropriate amount of Ether as gas to their transactions to incentivize miners or validators to process them. The more complex the operation, the higher the gas requirement and, consequently, the transaction fee. Gas fees maintain network security and prevent spam or misuse

of the Ethereum blockchain.
