Ethereum is an open-source, decentralized blockchain platform that allows for the execution of smart contracts and dApps — thus expanding the function of blockchain technology beyond just cryptocurrency transactions. It was founded by Vitalik Buterin along with co-founders such as Gavin Wood and Joseph Lubin, and has grown into the largest smart contract blockchain ecosystem, with hundreds of contributors working together to grow the platform.
Vitalik Buterin, at age 19, publishes the Ethereum whitepaper describing a 'next-generation smart contract and decentralized application platform,' inspired by Bitcoin's limitations

The largest DeFi ecosystem, highest stablecoin volumes, and largest developer community (28.5% ETH staked, L2 scaling) - Ethereum is currently leading. Solana offers much faster transaction processing than Ethereum but is experiencing frequent outages and lower levels of liquidity. Ethereum’s upcoming upgrades (Glamsterdam, Heze-Bogota) are targeting 10x the current processing capacity as early as 2026.
Use Ethereum for mature DeFi/RWAs, use Solana for fast-speed consumer applications.
As a decentralized network, Ethereum has better institutional adoption (ETF holdings), whereas Binance Smart Chain (BSC) is more centralized and offers lower security guarantees at a lower cost to transact.
Use Ethereum for institutional/compliance requirements; use BSC for cheap retail trading.
Ethereum processes transactions faster due to its large and established ecosystem, while Cardano is focused on research but trails Ethereum significantly in terms of Total Value Locked (TVL) and actual use cases. Analyst forecasts suggest that Ethereum will continue to have greater momentum going forward.
Use Ethereum for producing DeFi, use Cardano for experimental/academic projects.
Ethereum has the largest amount of single-chain liquidity; Polkadot is best for facilitating interoperability among chains but causes fragmentation of assets across multiple parachains.
Use Ethereum for creating a singular pool of liquidity; use Polkadot for building ecosystems using cross-chain communication.
Ethereum is decentralized and there is no single organization providing official support — use community forums such as Discord and Stack Exchange to get assistance. Be aware of anyone claiming to be an official representative — they may be attempting to scam you.
Ethereum will not assist with processing or speeding up transaction times — check the current gas prices and wait or utilize tools such as Etherscan. Also contact the customer service for your wallet or exchange provider for assistance.
Bitcoin is primarily designed as a form of digital currency; Ethereum is a programmable blockchain which provides support for creating smart contracts and dApps. Ethereum provides the ability to create more complex applications and services beyond simply transferring value.
All Ethereum transactions are public and immutable. To protect yourself, always keep your private keys safe, do not share them and store your funds in a hardware wallet along with safely storing your seed phrase.
There is no direct method to connect to the Ethereum network, therefore download one of the clients (Geth, Nethermind or Besu) and follow the instructions provided on their documentation. Join their respective Discord servers if you need any assistance with the setup process and start by testing out the network using testnets before deploying smart contracts.
Testnets such as Sepolia and Holesky allow developers to test smart contracts with "fake" ETH which is provided through faucets. While they are identical to mainnet, none of this ETH has actual monetary value.
Utilize Solidity when developing smart contracts and use either Remix or Hardhat to deploy them. When building a frontend use either ethers.js or web3.js. For additional resources regarding development see ethereum.org/en/developers.
The current upgrade of Ethereum are called sequential updates (i.e., Denecun, Pectra). Check out ethereum.org for the most up-to-date roadmap. The most recent upgrades have focused on scaling using roll-ups.
The top smart contract platform for Web3 and the biggest decentralized application developer ecosystem in the world is Ethereum. With a massive developer ecosystem and huge amount of liquidity, Ethereum has become the default platform for all blockchain innovation, while the scalability issues that exist today will be solved by layer two solutions. A key part of the proof-of-stake design of Ethereum is the security provided by the network, as well as the large amount of tools available to developers, which makes Ethereum the best option for blockchain-based projects and applications. However, because of the decentralized nature of the platform, user self-reliance is required for decentralized support.
Serious Web3 Development Will Require You To Have Technical Competence And Self-Recover When Things Go Wrong.
Because Of Its Decentralized Nature, Ethereum Has No Official Support Channels, Instead It Relies On Community Provided Support Through Discord, Stack Exchange, Project-Specific Forums. Most Of The Primary Support For Ethereum Comes From Developer Communities Around Clients (Geth, Nethermind), Tooling (ethers.js, Hardhat), Block Explorers (Etherscan), As Well As Standard Json-Rpc API Integration, With Excellent Testnet Infrastructure, But No Centralized SLAs.
Good - official ethereum.org pages, Etherscan documentation, and ecosystem project sites provide comprehensive decentralized support information. No centralized customer satisfaction metrics available.
A global developer ecosystem that includes over 100,000 questions on Ethereum Stack Exchange, large communities on Discord, and an annual conference called Devcon; most active blockchain developer community in the world.
A non-profit organization supporting the growth of ecosystems by providing funding to grow the ecosystem through its Ecosystem Support Program (ESP); also offers research and public good funding to help support ideas that are requested through its wishlist or request for proposals (RFP).
Many different execution clients (Geth is used by approximately 70% + of the Ethereum client base; Nethermind, Besu, Erigon, Reth) and many consensus clients (Lighthouse, Prysm, Lodestar) exist; so that there is no one single point of failure on the network.
Approximately 150 layer 2 rollups (Optimism, Arbitrum, Base, zkSync) process over 90% of all Ethereum transaction volume; continued improvements from danksharding and other future upgrades will improve the overall scalability of the Ethereum network.
The beacon chain and proof-of-stake has been live since 2022 and has had no successful attacks; a total of $30 billion dollars or more have been staked as security for the network; formal verification tools are increasingly being used.
| L2 Solution | Type | TVL | TPS |
|---|---|---|---|
| Arbitrum One | Optimistic Rollup | $10B+ | 40 TPS |
| Optimism | Optimistic Rollup | $5B+ | 30 TPS |
| zkSync Era | ZK Rollup | $500M+ | 100+ TPS |
| Base | Optimistic Rollup | $2B+ | 30 TPS |
