Ethereum (ETH), launched in July 2015, is the native cryptocurrency of the Ethereum blockchain, a decentralized, open-source Layer 1 blockchain that pioneered smart contracts. Founded by Vitalik Buterin and others, Ethereum enables developers to build decentralized applications (dApps) for DeFi, NFTs, gaming, and more. ETH powers transaction fees (gas), staking, and governance within the ecosystem.

Key Features

  • Smart Contracts: Programmable contracts automate trustless transactions, supporting 350K+ dApps.
  • High Adoption: Hosts ~60% of DeFi’s $220B total value locked (TVL) and major Layer 2 solutions like Arbitrum and Polygon.
  • Proof-of-Stake (PoS): Energy-efficient consensus post-Merge (2022), with 33M+ ETH staked.
  • Ecosystem: Supports tokens like USDT, UNI, and ENS, with 17.4M active addresses weekly.

ETH Token

  • Purpose: Used for gas fees, staking, and as a store of value or collateral in DeFi.
  • Supply: Circulating supply of ~120.7 million ETH, with no fixed max supply (deflationary since EIP-1559).
  • Contract Address: Native to Ethereum; CoinGecko CMC. Add to wallets like MetaMask or Trust Wallet.

Who Are the Founders of Ethereum?

Ethereum was co-founded by Vitalik Buterin, Gavin Wood, Anthony Di Iorio, Charles Hoskinson, and others in 2013. The Ethereum Foundation, based in Switzerland, oversees development. Funded by a 2014 ICO raising $18.3M, Ethereum launched with an ROI of ~270% annually. Buterin remains a key figure, guiding protocol upgrades.

What Makes Ethereum Unique?

Ethereum stands out for its smart contract platform:

  • Developer Ecosystem: Largest dApp ecosystem, with tools like Solidity and Ethers.js attracting 1M+ developers.
  • Layer 2 Scaling: Solutions like Optimism and Base reduce gas fees (~$0.01-$0.10) and boost TPS to 100K+.
  • Institutional Support: Backed by BlackRock, Fidelity, and spot ETH ETFs, with $1.9B in weekly inflows.
  • Deflationary Mechanism: EIP-1559 burns ~3M ETH annually, reducing supply during high network activity.

ETH Network Upgrades (2025)

  • Pectra Hard Fork (June 2025): Enhanced EVM efficiency and validator stability, boosting TPS by 20%.
  • Sharding Progress (Q2 2025): Split database into 64 shard chains, lowering node requirements and gas fees.
  • Layer 2 Growth (May 2025): Arbitrum and Base hit 7.55x adoption, processing 80% of Ethereum’s transactions.

How Is ETH Secured?

Ethereum and ETH are secured through:

  • PoS Consensus: Validators stake ETH (minimum 32 ETH) to secure the network, with slashing for misbehavior.
  • Validator Network: Over 1M validators globally, ensuring decentralization.
  • Smart Contract Audits: Regular audits by firms like ConsenSys and Trail of Bits mitigate vulnerabilities.
  • Governance: ETH holders and developers vote on upgrades via EIPs, fostering community-driven security.

Conclusion

Ethereum (ETH) powers the world’s leading smart contract blockchain, driving innovation in DeFi, NFTs, and Web3. With its robust developer ecosystem, Layer 2 scaling, and institutional adoption via ETFs, Ethereum remains a cornerstone of the $3.5T crypto market. Recent upgrades like Pectra and sharding position it for scalability and global impact.
