Alephium is built on a novel sharding algorithm called BlockFlow. It leverages a stateful UTXO model and DAG data structure to deliver efficient and practical sharding. This enables Alephium to natively support over 10,000 transactions per second while preserving a seamless 'single-chain' user experience.

Alephium's Proof Of less Work is a simple, consistent and robust consensus mechanism for achieving decentralization while reducing the energy consumption by over 87% compared to classic Proof of Work. On Alephium, anyone can run a full node and verify on-chain data,'Don't trust, verify'.

Alephium's stateful UTXO model combines the advantages of the UTXO and account models. It supports mutable states, like those found in Ethereum, for smart contracts while leveraging the security benefits of the UTXO model for assets.

Alephium enhances developer experience and security with its Virtual Machine, SDK, and performance-optimized programming language. Its MEV-aware design and built-in security measures eliminate common attack vectors, such as reentrancy attacks, unlimited authorization and flash loans. Alephium allows devs to focus on what matters and pioneers entirely new possibilities for smart contracts, dApps and tokens.
