# Alephium Blockchain

What is Alephium? Alephium is a sharded L1 blockchain that aims to scale and improve on Bitcoin’s core technologies while offering smart contracts and dApps capabilities.

It uses a stateful UTXO model that combines the best of both worlds: high scalability, security, and programmability. It also introduces a novel consensus algorithm called Proof-of-Less-Work (PoLW) that reduces energy consumption by 87.5% compared to Bitcoin.

&#x20;**Features:**

* **It scales through sharding**&#x20;
* **It is programmable & secure**
* **It is less energy consuming thanks to POLW**&#x20;
* **It improves on chain structure with its own custom VM (Alphred)**&#x20;
* **It has its own programming language for dApps**

**Tokenomics** \
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 next \~80 years. Of these 140M tokens&#x20;
* Pre-sales and future strategic private sales. Vesting periods varying from 2 to 4 years. \[ 80M tokens (8%) ]
* Community and ecosystem development. Locked on-chain for 4 years and vested quarterly. \[ 30M tokens (3%) ]
* Treasury & Team. Locked on-chain for 3 years, and vested quarterly. \[ 30M tokens (3%) ]\
  Mining Rewards. These tokens will be used for mining rewards over the next \~80 years. They ensure the processing of transactions and the execution of smart contracts on the Alephium blockchain. \[ 860M tokens (86%) ]

**Bridge**\
Team just announced their native bridge is about to launch anytime before 15th November 2023 The bridge will allow users to migrate stablecoins to Alephium's chain. This will bring significant amounts of capital from the Ethereum chain to Alephium!

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://alphdolphins.gitbook.io/alphdolphins-nfts-or-white-paper/informations/alephium-blockchain.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
