Ethereum vs Stellar

Key differences

Ethereum and Stellar target different layers of finance. Ethereum, live since 2015, is a general-purpose smart contract platform — a programmable global computer where developers build DeFi protocols, NFT marketplaces, and games without central control. Stellar, co-founded in 2014 by Jed McCaleb and Joyce Kim, is purpose-built for payments: moving value quickly and cheaply across currencies and borders, connecting banks, payment systems, and individuals.

Their consensus models differ. Ethereum is secured by Proof of Stake, with validators staking ETH. Stellar uses the Stellar Consensus Protocol, a federated agreement system without mining or staking rewards. Supply mechanics also diverge: ETH has no maximum supply, with about 120.7 million coins outstanding, issuance to stakers, and partial fee burning; XLM has no ongoing mining, with roughly 34.5 billion lumens circulating out of about 50 billion total, and the network is stewarded by the non-profit Stellar Development Foundation.

Ecosystem roles reflect their designs. Ethereum hosts the largest on-chain application economy, with billions in DeFi value and an extensive Layer 2 scaling ecosystem. Stellar's ecosystem centers on Anchors — trusted entities that hold deposits and issue on-chain representations of fiat currencies — plus stablecoins like USDC and tokenized real-world assets, serving remittances and financial inclusion.

ETH is the fuel of a maximally programmable platform; XLM is the native asset of a lean network optimized for currency transfer.
