What Is Alephium?

1. What Is Alephium?

Alephium is a high-performance Layer 1 blockchain that brings scalability, security, and smart contract functionality together in a unique architecture. Designed to support decentralized applications (dApps) and DeFi protocols at scale, Alephium leverages a novel sharding mechanism and Proof-of-Less-Work (PoLW) consensus to deliver low-cost, high-throughput transactions without compromising decentralization. Unlike many Layer 1 blockchains that suffer from congestion and centralization risks, Alephium is built to handle real-world demands efficiently while staying secure and energy-conscious.

2. Why Alephium Was Created

Alephium was created to solve the blockchain trilemma: achieving scalability, security, and decentralization simultaneously. Traditional blockchains like Bitcoin offer strong security but suffer from limited throughput. Others, like Ethereum, offer smart contracts but struggle with congestion and high gas fees. Many newer blockchains improve scalability but compromise on decentralization or security.

Alephium addresses these limitations by introducing a new consensus algorithm and a unique sharding model, enabling the network to process thousands of transactions per second without excessive energy consumption or centralization. The goal is to make blockchain usable at scale for both financial and non-financial applications.

3. How Alephium Works

1. Sharded Blockchain Structure – Alephium implements a stateful UTXO model and combines it with sharding to parallelize transaction processing, drastically improving scalability.
2. Proof-of-Less-Work (PoLW) – Alephium replaces traditional energy-intensive Proof-of-Work with a more efficient variant that maintains security while lowering energy use.
3. Smart Contracts on UTXO – Alephium introduces a new virtual machine and programming language (Ralph) that brings smart contract capability to the UTXO model, blending Bitcoin’s security with Ethereum’s programmability.
4. Single-Step Cross-Shard Transactions – Users can send and receive funds across shards seamlessly and atomically, eliminating the complexity typically seen in sharded systems.
5. On-Chain Governance – The network supports decentralized decision-making through community-driven governance mechanisms.
6. Decentralized Infrastructure – The project promotes a truly decentralized node architecture, avoiding the validator centralization common in many PoS-based chains.

4. Key Features of Alephium

• PoLW Consensus: A greener alternative to Proof-of-Work

6. What Is the $ALPH Token?

$ALPH is the native utility token of the Alephium network. It plays multiple critical roles within the ecosystem:

• Transaction Fees: Used to pay for network and smart contract operations
• Staking & Security: Earned through PoLW mining and used to secure the network
• Governance: Grants token holders the ability to propose and vote on protocol decisions
• Smart Contract Interaction: Needed to deploy and interact with dApps on Alephium
• Store of Value: A digital asset with embedded utility and network demand
