Alephium overview

๐Ÿฅ What is Alephium?โ€‹

Alephium is the first live Layer 1 sharded blockchain scaling and improving on Bitcoin core technologies, Proof of Work & UTXO. It delivers a highly performant, secure DeFi & Dapps platform with enhanced energy efficiency.

  • Like Bitcoin, but more programmable & energy efficient.
  • Like Ethereum, but more secure & scalable.
  • Like Solana, but more decentralised & trustless.

๐Ÿ’Ž Why is Alephium special?โ€‹

On top of an awesome team, an outstanding community and a lot of energy, here are our technical specificities:

It scales through sharding. Alephium is built on a novel and complete sharding algorithm called BlockFlow. It improves on the UTXO model of BTC to make it scalable, and uses DAG data structure to reach consensus between different shards. This will allow up to 10โ€™000 Transactions Per Second (currently more than 400 TPS vs Bitcoins 7 TPS).

It is programmable & secure. Alephium proposes a stateful UTXO model offering layer-1 scalability and the same level of programmability as the account model implemented on ETH, whilst being more secure.

It is less energy consuming thanks to POLW. Proof of Less Work combines physical work and Coin economics to dynamically adjust the work required to mine new blocks. Given the same network conditions, Alephium only uses โ…› of the energy compared to Bitcoin.

It improves on chain structure with its own custom VM (Alphred). It resolves many of the critical issues of the current dApps platforms with huge improvements on security, development experience and introductions of new paradigms such as trustless P2P smart contracts transactions.

It has its own programming language for dApps. Ralph is similar to the Rust syntax, hence its name. It allows to build efficient and secure smart contracts easier than Solidity for example. It is specifically designed to facilitate the creation of Decentralized Finance applications!

Putting all these innovations together, Alephium delivers a highly demanded solution in the industry: a scalable blockchain improving on mature ideas from Bitcoin to deliver reliable, powerful and secure DeFi and dApps capabilities. And weโ€™re live!

๐Ÿ›ฃ๏ธ Roadmapโ€‹

The network is young and growing rapidly. We will update the roadmap to reflect the latest priorities.

Core Platform

  • Improve the robustness, efficiency and dev-experience of the full node
  • Improve documentation of the core infrastructure
  • Improve the Alephium SDK with more features
  • Improve the robustness and efficiency of the explorer backend
  • Bridge development, testing, and launch
  • Leman Network Upgrade for cross-chain interoperability
  • dApp support in the desktop wallet
  • DEX development, testing, and launch
  • Mobile wallet
  • Hardware wallet integration


  • Website revamp
  • Build-up community engagement & marketing initiatives (hackathon, AMAs, community competitions, campaigns, etc)
  • Key industry events (PBWS, EthCCand others)
  • DEX listing (after the deployment of the bridge)
  • Additional CEX listing
  • 3rd party dApps (NFT, DEX, stablecoin) on Alephium

๐Ÿ›ก Our tokenomicsโ€‹

The token supply on Alephium is limited with a hardcap of 1 billion. At Mainnet Launch (11.8.21), an initial supply of 140M tokens (14% of the hardcap) was mined with the genesis block. The remaining supply of ALPH tokens will be mined over the years. Of these 140M tokens:

80M tokens (8%) ๐Ÿค Pre-sales and future strategic private sales. Vesting periods varying from 2 to 4 years.

30M tokens (3%) ๐Ÿ’ก Community and ecosystem development. Locked on-chain for 4 years and vested quarterly.

30M tokens (3%) ๐Ÿง‘โ€๐Ÿ’ป Treasury & Team. Locked on-chain for 3 years, and vested quarterly.

860M tokens (86%) ๐ŸŒŠ Mining Rewards. These tokens will be used for mining rewards over years. They ensure the processing of transactions and the execution of smart contracts on the Alephium blockchain.

In addition, half of the transaction fees are burned with each block and Proof of Less Work enables internal mining cost through burning when the hashrate and energy consumption are significantly high.
