Ethereum ETH

Ethereum (ETH) is a decentralized, programmable blockchain and the leading platform for smart contracts and decentralized applications. Launched in 2015, it lets developers deploy code that runs exactly as written, powering everything from decentralized finance to NFTs. Its native asset, ether (ETH), is used to pay for computation and secure the network.

How Ethereum works

At the heart of Ethereum is the Ethereum Virtual Machine (EVM), a global, shared runtime that executes smart contracts. Anyone can write a contract, deploy it to the network, and have it enforced automatically by thousands of nodes. This turns the blockchain into a general-purpose computing platform rather than a ledger for a single currency.

Since the 2022 upgrade known as The Merge, Ethereum secures itself with proof of stake. Validators lock up ether as a stake and are chosen to propose and attest to blocks; honest behavior earns rewards while misconduct can lead to penalties or slashing. This replaced energy-intensive mining and cut the network's energy use dramatically.

Gas and fees

Every operation on Ethereum costs gas, a unit that measures computational effort and is paid in ether. Fees rise when the network is busy and fall when it is quiet. To improve scalability, much activity now happens on Layer 2 networks that batch transactions and settle back to Ethereum, lowering costs while inheriting its security.

What Ethereum is used for

• Decentralized finance (DeFi): lending, trading, and stablecoins run on Ethereum smart contracts.
• Tokens: most ERC-20 tokens and many stablecoins are issued on Ethereum.
• NFTs and digital ownership: the ERC-721 standard originated here.
• Staking: holders can stake ether to help secure the network and earn rewards.
• Settlement for Layer 2s: rollups post data and proofs back to Ethereum.

Tokenomics & supply

Ether has no fixed maximum supply, but its issuance is now modest and tied to staking rewards. A fee-burning mechanism introduced in 2021 destroys part of every transaction fee, so during periods of high activity the network can burn more ether than it issues, making net supply slightly deflationary at times.

This combination of low issuance and fee burning means ether's supply dynamics depend heavily on network usage rather than a rigid schedule. Staked ether also reduces the freely circulating amount, since validators commit it to securing the chain.

Risks and considerations

Ether is volatile, and the platform's complexity introduces smart contract risk: bugs or exploits in applications built on Ethereum can lead to loss of funds even when the base layer functions correctly. Fees can spike during congestion, and the ongoing transition of activity to Layer 2s adds bridging and ecosystem fragmentation considerations.

Regulatory questions around staking, tokens, and DeFi remain unsettled in many jurisdictions. As with any crypto asset, users should research applications carefully, manage custody securely, and understand that on-chain transactions are generally irreversible.
