Alephium Overview
Quickstart
Welcome to Alephium!
What is Alephium?
The Web3 you were promised. Scalability, smart contracts, and real decentralization without the tradeoffs.
Alephium unites the best of both worlds: the decentralized, censorship-resistant security of Proof-of-Work & UTXO, and the speed, scalability, and usability expected from modern smart contract platforms.
Why is Alephium special?
On top of an awesome team, an outstanding community and a lot of energy, here are our technical specificities:
⚡Fast: 8 second block time, 2 BPS network throughput. Each chain on Alephium now produces a block every 8 seconds. With parallel processing across the network, Alephium achieves 2 blocks per second on average, matching the speed of leading PoS networks without sacrificing decentralization.
⛓️Scalable: 20,000+ tps, single-chain experience. Alephium's BlockFlow sharding processes over 20,000 transactions per second while eliminating cross-chain complexity, delivering high throughput and the simplicity of a single-chain environment.
🔒Secure: Security by design. Alephium offers a robust, developer-friendly environment with built-in protections against common vulnerabilities. Its MEV-aware architecture and native safeguards prevent threats like reentrancy attacks, unlimited approvals, and flash loan exploits.
🌱Sustainable: The best of PoW, 87% less energy. Alephium's Proof-of-Less-Work consensus delivers true decentralization with a fraction of the energy. It retains the security and simplicity of traditional PoW while cutting energy use by over 87%.
🧩Programmable: Stateful UTXO, the best of Bitcoin and Ethereum. Alephium's stateful UTXO model combines Ethereum's flexibility with Bitcoin's security. It enables powerful smart contracts with mutable state while ensuring robust, UTXO-based asset protection.
🧑💻Dev-friendly: Custom VM & language built for performance. Alephium empowers developers with its purpose-built Virtual Machine (Alphred), intuitive SDK, and high-performance programming language (RALPH), enabling efficient development and unlocking new possibilities for smart contracts, dApps, and tokens.
All of this runs natively on a single Layer 1, with no dependence on bridges, sequencers, L2s, or rollups, avoiding complexity, fragmentation, and UX tradeoffs. Alephium unites the best of both worlds: the decentralized, censorship-resistant security of Proof-of-Work, and the speed, scalability, and usability expected from modern smart contract chains.
Alephium delivers the Web3 you were promised.

Built on Alephium
Alephium powers a diverse ecosystem of innovative dApps. Dive in!
Tokenomics
Since the Danube upgrade, ALPH emissions are no longer capped and the supply is unlimited.
| Category | Allocation | Vesting/Lock |
|---|---|---|
| Mining Emissions | Unlimited | 500 minutes lock |
| Burned | - All transaction fees - Proof of Less Work | None |
| Seed/Private Sales Allocation | 80M | Unlock quarterly over 2 to 4 years |
| Ecosystem Allocation | 30M | Unlock quarterly over 4 years |
| Treasury Allocation | 30M | Unlock quarterly over 3 years |
If you need the endpoints, find them here: Total Supply = Circulating Supply + Reserved Supply + Locked ALPH

Get ALPH
The native token of Alephium. You can get it through your wallet, exchanges, other networks or your peers.
On-Ramps
You can get ALPH directly from the Alephium mobile and desktop wallets with a debit/credit card, bank transfer, or even Apple Pay. Geographical restrictions apply. See announcement.
Centralised Exchanges
Centralised Exchanges (CEX) are platforms where ALPH is available using traditional currencies. They maintain custody over the ALPH you get until you transfer it to a wallet under your control. The full list of centralized exchanges is available on CoinMarketCap and Coingecko.
DEXs
ALPH is available natively on Elexium, Ayin, and Nightshade, as well as on Uniswap (wrapped ALPH via the Ethereum Bridge) and PancakeSwap (via the BSC Bridge). For a full list of decentralized exchanges, see Coingecko.
⚠️ Some pairs have low liquidity, always check liquidity before choosing a venue or bridging an asset.
Bridged ALPH
ALPH is also available on other networks such as Ethereum (via Uniswap) and BSC (via PancakeSwap). You can use the Alephium Token Bridge to move bridged ALPH between these networks and the native Alephium network.
From your peers
Once you have an Alephium wallet, you just need to share your address to start sending and receiving ALPH and other tokens directly with others. Get a wallet here.
Contribute as Developers
Alephium is public, fully open source and decentralized. Discover and contribute to Alephium's main projects on GitHub.
If you are building a dApp, get start from here. Once released, let everyone know by sending a PR to add your project to the awesome-alephium repo. The Alephium Brand Guide might also come in handy.
