Ethereum (ETH) — The EVM L1 Settlement Layer
Ethereum is the original general-purpose smart-contract chain and the largest EVM L1 by total value locked, holding $36.42B across DeFi as of June 2026. Since The Merge in 2022, it has run on PoS Gasper — a hybrid of Casper FFG finality gadget and LMD GHOST fork choice — secured by the largest validator set in crypto. Blocks land every 12 seconds; cryptoeconomic finality takes 768 seconds (~12.8 minutes) across two epochs. Throughput is deliberately conservative (~15 TPS typical, 30 TPS theoretical max) because Ethereum optimizes for verifiability, neutrality, and security over raw speed, pushing high-throughput execution to its rollup stack instead.
Ethereum (ETH) is the EVM L1 that defined programmable money. Launched 30 July 2015 by Vitalik Buterin and a small founding team, it introduced the Ethereum Virtual Machine — a Turing-complete, account-based runtime — and the ERC-20 / ERC-721 / ERC-1155 token standards that the rest of the industry has reused. Today Ethereum is the settlement and data-availability layer for the broader EVM economy: rollups like Arbitrum ($2.65B canonical bridge TVL on L1), Base ($2.29B), and OP Stack chains post their state roots and blobs back to Ethereum to inherit its security. The native asset, ETH, is both gas and a yield-bearing staking asset; since EIP-1559, the base fee is burned, turning fee pressure into a structural sink on supply. Ethereum is the home of the deepest liquidity in crypto — $80.08B of USDT (42.86% of total USDT supply) circulates as ERC-20 — making it the de-facto pricing venue for stablecoins, RWAs (Paxos Gold $1.98B), restaking (EigenCloud $4.4B), and the most mature DEX, lending, and derivatives stacks. It is the chain you choose when finality, liquidity depth, and credible neutrality matter more than per-transaction cost. AllSwap routes non-custodial cross-chain swaps that originate from, terminate on, or settle through Ethereum, treating it as the canonical reference chain for EVM assets.
About Ethereum
Ethereum launched its genesis block on 30 July 2015, four years after Vitalik Buterin's original 2013 whitepaper proposed a 'world computer' — a single, replicated state machine that could execute arbitrary code paid for in a native unit (gas). The early network ran on Ethash proof-of-work and was already differentiated from Bitcoin not by faster blocks (12-second blocks were chosen as a practical floor under uncle-rate constraints) but by the EVM itself: a 256-bit, account-based, Turing-complete virtual machine with deterministic gas pricing. That single architectural decision — making the chain a programmable execution layer rather than a payment ledger — is the source of every later EVM L1, every rollup, and most of the on-chain economy you see today.
On 15 September 2022, Ethereum completed The Merge, atomically swapping its PoW execution layer for a PoS consensus layer (the Beacon Chain) that had been running in parallel since December 2020. The new consensus is called Gasper — a composition of Casper FFG (a finality gadget that justifies and finalizes checkpoints every 32-slot epoch) and LMD GHOST (the fork-choice rule that weights validator attestations). Validators stake 32 ETH each; the active set is currently the largest in any PoS network, and that breadth — not block speed — is what Ethereum sells. Finality is reached in two epochs (~12.8 minutes, hence the 768-second figure), and reverting a finalized block requires slashing roughly one-third of all staked ETH, an attack with an explicit, multi-billion-dollar economic cost.
The economic design pairs that consensus security with two reinforcing mechanisms. EIP-1559 (deployed in the August 2021 London upgrade) replaced first-price auction fees with a dynamic base fee that is burned, plus an optional priority tip paid to proposers. This makes ETH issuance partly net-negative when network demand is high, tying token economics to genuine block-space demand rather than pure inflation. The Dencun upgrade (13 March 2024) added EIP-4844 proto-danksharding, introducing blob-carrying transactions: a separate, cheaper data lane sized specifically for rollup data, which collapsed L2 posting costs by an order of magnitude and is the technical reason Base, Arbitrum, and OP Stack chains can charge sub-cent fees today.
What you should take from this: Ethereum is not trying to compete with Solana or BSC on raw TPS, and the numbers in this page reflect that. 15 TPS typical and 768-second finality are deliberate trade-offs against a $36.42B TVL — the largest of any chain — and a validator set whose collusion cost is intentionally prohibitive. The execution scaling story has been outsourced to rollups, while Ethereum L1 specializes in settlement, data availability, and credibly neutral final state. This is the chain you trust with the bottom of the stablecoin order book and the top of the institutional RWA stack.
Ethereum technical parameters
Ethereum's technical profile is misread more often than any other chain. The 12-second block time and 768-second finality look slow next to Solana (0.4s blocks, 12.8s finality) or Aptos (0.15s blocks, 0.65s finality), but they are deliberate, not accidental. Every parameter on this page reflects a single design priority: make the cost of attacking finality so high that institutions, rollups, and high-value DeFi can settle there without a backup plan.

Consensus mechanism
Ethereum runs Gasper, which is two separate algorithms fused at the protocol level. LMD GHOST is the fork-choice rule: every 12 seconds a proposer is pseudo-randomly selected from the active validator set, builds a block, and attesters vote on it. LMD GHOST (Latest Message Driven Greedy Heaviest Observed Sub-Tree) picks the heaviest subtree of attestations as the canonical chain head, so honest validators converge on the same block within one slot under normal network conditions. Casper FFG (Friendly Finality Gadget) sits on top: every 32 slots forms an epoch, and validators cast votes that justify and then finalize epoch checkpoints. A block is finalized once two consecutive epochs are justified — that is where the 768-second (~12.8 minute) finality figure comes from. Crucially, finality here is economic, not probabilistic: reverting a finalized block requires at least one-third of all staked ETH to vote inconsistently, which gets that stake slashed by protocol. With the largest validator set in PoS, the dollar cost of such an attack is in the multiple-billions, which is why Ethereum finality is widely treated as the highest-assurance settlement in crypto.
Performance context
15 TPS typical (30 TPS theoretical max) is calculated against an average gas limit per block, not a marketing number. In practice that means a base-layer transaction costs more and confirms slower than on any high-speed L1 on this site — and that is exactly what the design wants. Ethereum L1 is now positioned as the settlement and data-availability layer; execution throughput is supposed to happen on rollups. Post-Dencun (March 2024), blob transactions give rollups a dedicated, ~3 MB-per-block data lane that is priced independently of the regular fee market. Base alone routinely lands 1,500 TPS while paying Ethereum cents per blob. So the honest framing is: 15 TPS at the base layer enables collectively thousands of TPS across the rollup stack, all inheriting Ethereum's 768-second finality.
Ethereum ecosystem map
Ethereum is not just the chain with the largest TVL; it is the chain whose top eight protocols span every primitive in DeFi. The $36.42B locked breaks down across staking infrastructure, lending, synthetic dollars, restaking, stablecoin bridges, canonical L2 bridges, and tokenized RWAs — a coverage profile no other L1 reproduces.
Infrastructure
SSV Network leads the entire ecosystem with $11.64B TVL, providing distributed validator technology (DVT) that splits a single validator's signing duties across multiple operators. It is the largest single protocol on Ethereum and underpins much of the institutional staking stack.
Lending
Sky Lending (the rebranded MakerDAO CDP stack) holds $5.90B in collateral backing the USDS/DAI stablecoin system — the longest-running, most battle-tested CDP design on any chain, and the original primitive for decentralized over-collateralized debt.
DEX / Synth
Ethena USDe runs $4.50B of basis-trade collateral, generating a synthetic dollar from delta-neutral perpetual positions. It is Ethereum-native because the basis trade requires the deep, regulated CEX hedging venues and the deepest ETH/stETH spot liquidity, both of which live here.
Infrastructure
EigenCloud (EigenLayer's restaking platform) holds $4.44B, letting stakers re-pledge their ETH to secure additional services (AVSs). Restaking only makes economic sense on Ethereum because it monetizes the same validator set that is already securing the highest-TVL chain in crypto.
Bridge
USDT0 ($3.67B) and the canonical Arbitrum Bridge ($2.65B) and Base Bridge ($2.29B) together hold over $8.6B in bridge TVL. These aren't third-party bridges — they are the official entry/exit ramps for the major rollups, which is why Ethereum is effectively the reserve layer for L2 ETH and USDC.
Infrastructure
Paxos Gold ($1.98B) is the largest tokenized real-world asset by chain TVL — 1:1 physical gold custodied by Paxos Trust. Ethereum hosts the deepest RWA stack in crypto (tokenized treasuries, gold, equities) because issuers want SEC-recognized custodians settling on the most credibly neutral chain.

Ethereum vs peers
Ethereum's EVM L1 peer set (BSC, Avalanche, Tron, Gnosis, Cardano) is the cleanest comparison because every chain here either runs an EVM or directly competes for the same DeFi user base. The numbers tell a sharp story: Ethereum is slower than all of them, more expensive than all of them, and holds more TVL than all of them combined.
| Chain | Block | Finality | TPS | TVL |
|---|---|---|---|---|
| Ethereumcurrent | 12 s | 12.8 min | 15 | $36.42B |
| BSC | 750 ms | 1.88 s | 200 | $5.08B |
| Avalanche | 2 s | 1.5 s | 50 | $480.08M |
| Gnosis | 5 s | 16 min | 30 | $65.92M |
| Tron | 3 s | 57 s | 100 | $4.37B |
| Cardano | 20 s | 10 min | 10 | $92.24M |
Comparison insights
- TVL gap is structural, not marginal. Ethereum's $36.42B TVL is 7.2× BSC ($5.08B), 8.3× Tron ($4.37B), 76× Avalanche ($480M), 395× Cardano ($92M), and 552× Gnosis ($66M). Every other EVM L1 in this peer set combined ($10.09B) is still 3.6× smaller than Ethereum alone — capital concentration this skewed reflects a long-running flight to the highest-assurance settlement venue.
- Ethereum trades raw throughput for finality assurance. At 15 TPS typical it sits below BSC (200), Tron (100), Avalanche (50), and Gnosis (30), and only just above Cardano (10). But its 768s finality is economically backed by the largest staked-value validator set in crypto, whereas BSC's 1.875s fast finality runs on a 21-validator PoSA ring and Tron's 57s finality on 27 Super Representatives — both significantly more centralized trust models.
- USDT distribution shows the dominance is real-money, not just locked TVL. Ethereum holds $80.08B of USDT (42.86% of total supply), second only to Tron ($88.34B, 47.28%) — but Ethereum's USDT lives inside an order-book of lending, DEX, and derivatives liquidity that Tron's USDT (mostly transfer-only) does not have. BSC sits a distant third at $9.18B (4.91%).
- The Merge made Ethereum the only large-cap EVM L1 with credible neutrality. BSC's PoSA validators are a known set of mostly Binance-aligned operators; Tron uses 27 elected DPoS Super Representatives; Avalanche and Gnosis are PoS but with much smaller validator counts and TVL. Ethereum's tens of thousands of validators, geographically distributed, are the reason Sky, Ethena, and Paxos chose to anchor multi-billion-dollar collateral here rather than on a faster peer.
- Genesis date matters for compounding. Ethereum (2015-07-30) had a 5-year head start on BSC (2020-09-01) and Avalanche (2020-09-21), 3 years on Tron (2018-05-31), and 2 years on Cardano (2017-09-29). That head start compounded into ERC-20 becoming the universal token standard, MetaMask becoming the default wallet, and Solidity becoming the default smart-contract language — network effects that the peer set has been unable to dislodge despite cheaper, faster execution.
Ethereum timeline
Ethereum's history is a sequence of upgrades and one defining crisis. The chain went live on 30 July 2015 with a PoW Frontier release; over the next seven years it shipped Homestead, Byzantium, Constantinople, Istanbul, and Berlin hard forks, gradually tuning gas pricing and adding precompiles. The defining incident came early: on 17 June 2016, an attacker exploited a reentrancy bug in The DAO smart contract and drained approximately $60M of ETH. The community, led by core developers, executed a controversial hard fork to refund affected holders; a minority refused and kept mining the original chain, which became Ethereum Classic (ETC). That split is still cited today as the canonical example of social-layer governance overriding code-is-law, and it set the precedent that Ethereum's social consensus matters as much as its protocol consensus. Five years later, the London upgrade (August 2021) shipped EIP-1559, replacing the auction fee market with a base-fee burn mechanism that has since burned millions of ETH and changed the asset's monetary properties. The Merge on 15 September 2022 was the largest live infrastructure migration in crypto history: the PoW execution layer was atomically replaced with the PoS Beacon Chain that had been running in parallel since December 2020. Issuance dropped roughly 90% overnight, energy consumption fell by more than 99.9%, and not a single block was lost. Most recently, the Dencun upgrade on 13 March 2024 activated EIP-4844 proto-danksharding, adding blob-carrying transactions — a dedicated, cheaper data lane sized for rollups. That single upgrade is the reason L2 transaction fees fell from dollars to fractions of a cent and is what made the modular roadmap economically real.

Developer reference
Ethereum's developer surface is the industry default. The official public RPC endpoint is https://ethereum.publicnode.com and the canonical block explorer is etherscan.io, which most other EVM chains have copied verbatim. Addresses are 20-byte hex strings, 0x-prefixed and EIP-55 checksum-cased; the same address format works across every EVM chain on this site (Ethereum, BSC, Avalanche, Arbitrum, Base, etc.), which is why MetaMask, Rabby, Frame, Coinbase Wallet, Ledger, and WalletConnect-compatible wallets all support Ethereum natively. The execution layer is the EVM with Solidity (and Vyper, Huff) as primary languages; the token standards — ERC-20 for fungibles, ERC-721 for NFTs, ERC-1155 for multi-token — were defined here and reused by every EVM peer. Tooling: Foundry and Hardhat for development, ethers.js / viem / web3.py for clients, and ethereum.org/developers as the canonical documentation portal. For consensus-layer interaction, the Beacon API spec is implemented by every CL client (Prysm, Lighthouse, Teku, Lodestar, Nimbus). Chain ID is 1.

Ethereum FAQ
01Is Ethereum decentralized?
By every measurable axis, Ethereum is the most decentralized large-cap smart-contract chain. It runs on the largest validator set in PoS — tens of thousands of independent validators, each staking 32 ETH — distributed across hundreds of node operators and geographies. There are five major consensus-layer client implementations (Prysm, Lighthouse, Teku, Lodestar, Nimbus) and four execution-layer clients (Geth, Nethermind, Besu, Reth), so no single codebase controls the network. The Merge in September 2022 removed mining concentration risk entirely. Compare this with EVM L1 peers like BSC (21 PoSA validators) or Tron (27 DPoS Super Representatives), and Ethereum's decentralization advantage is structural, not marketing.
02What is Ethereum's finality time?
Ethereum reaches economic finality in approximately 768 seconds (about 12.8 minutes) — two epochs of 32 slots each, where each slot is 12 seconds. Once finalized, reverting a block requires roughly one-third of all staked ETH to vote inconsistently, which the protocol slashes. That makes finality reversion economically irrational at the multi-billion-dollar scale. For most real-world use cases, single-slot confirmation (12 seconds) plus a few additional confirmations is sufficient; full 768s finality is what high-value DeFi, RWAs, and L2 bridges wait for.
03How does Ethereum compare to Solana or Aptos on speed?
Ethereum is significantly slower at the base layer: 12-second blocks and 768-second finality versus Solana (0.4s blocks, 12.8s finality) or Aptos (0.15s blocks, 0.65s finality). Typical TPS at L1 is around 15, versus Solana's ~3,000 typical and Aptos's ~800 typical. This is deliberate. Ethereum prioritizes verifiability and finality assurance for the L1, then scales execution through rollups (Arbitrum, Base, OP, Scroll, Starknet) that inherit L1 security. Post-Dencun, those rollups can collectively process thousands of TPS while posting cheap blob data to Ethereum L1.
04What is Ethereum's TVL and what does it cover?
Ethereum's DeFi TVL is $36.42B as of June 2026 — larger than any other chain by a wide margin. The composition is unusually broad: SSV Network ($11.64B distributed validator infrastructure), Sky Lending ($5.90B CDP collateral for USDS/DAI), Ethena USDe ($4.50B basis trade collateral), EigenCloud ($4.44B restaking), USDT0 ($3.67B bridge), canonical bridges to Arbitrum ($2.65B) and Base ($2.29B), and Paxos Gold ($1.98B RWA). No other EVM L1 reproduces this breadth across staking, lending, synth dollars, restaking, bridging, and tokenized assets.
05Why is ETH used for gas, and is the supply inflationary?
ETH is the native unit of gas: every operation in a transaction has a gas cost paid in ETH, which compensates validators for execution and state storage. Since EIP-1559 (August 2021), each transaction's base fee is burned instead of paid to the proposer, so high network demand turns ETH into a deflationary asset. Combined with the ~90% issuance cut from The Merge, ETH supply has been net-negative during multiple periods of sustained demand. Issuance now scales with validator count and is significantly below pre-Merge levels.
