Ethereum Fundamentals: Smart Contracts, Proof of Stake, and Staking
Summary
This guide explains Ethereum as a programmable blockchain and contrasts its role with Bitcoin’s focus on digital money. It describes how the Ethereum Virtual Machine runs smart contracts, how transactions consume gas, and how part of the fee is burned under EIP-1559. It also summarizes the move from proof of work to proof of stake, validator participation, staking rewards and slashing, and the use of Layer 2 rollups to expand capacity.
The article places these mechanisms in a timeline of major upgrades, including The Merge, Shapella, and Dencun, and outlines Ethereum’s intended scaling direction. It compares ETH’s utility and supply dynamics with Bitcoin’s capped supply, while noting that Ethereum has no fixed issuance cap and that fee burning can make supply deflationary at times. The discussion is introductory and mixes established mechanisms with roadmap expectations. Staking yields, network throughput, adoption measures, and future upgrade plans are time-sensitive; the guide’s investment framing does not establish future returns.
Key ideas
- Ethereum uses the EVM to execute smart contracts and decentralized applications.
- Network actions require gas fees, part of which is burned under the EIP-1559 fee mechanism.
- Ethereum’s proof-of-stake system uses staked ETH to support block validation and exposes validators to slashing.
- Layer 2 rollups bundle transactions and post summaries to Ethereum to reduce costs and increase capacity.
- ETH’s investment profile is linked to network use and staking, while its supply model differs from Bitcoin’s fixed cap.
