# DAppNode package _Alephium_

Alephium is a sharded blockchain that makes programmable money scalable and secure. For more information, please visit the [wiki](https://wiki.alephium.org/).

More information about the source project can be found at [their official website](https://alephium.org)

### Why _Alephium_ ?

The protocol's innovations extend battle-tested ideas from [Bitcoin](https://bitcoin.org/bitcoin.pdf) and [Ethereum](https://ethereum.org/en/whitepaper/):

* BlockFlow algorithm based on UTXO model enables sharding and scalability for today (code + [algorithm paper](https://github.com/alephium/research/blob/master/alephium.pdf))

  * The first sharding algorithm that supports `single-step cross-shard transactions`, offering the same user experience as single chain

  * Simple and elegant `PoW based sharding`, does not rely on beacon chain

* `Stateful UTXO model` combines the advantages of both eUTXO model and account model (see code, wiki to come)

  * Tokens are first-class citizens and UTXO-based, which are `owned by users` directly instead of contracts

  * Offer the same expressiveness as `account model`. DApps can be easily built on top of it with better security

  * Support `multiple participants` in a single smart contract transaction. Multiple calls can be packed into a single transaction too.

* Novel VM design resolves many critical challenges of dApp platforms (see code, wiki to come)

  * Less IO intensive

  * Flash loan is not available by design

  * Eliminate many attack vectors of EVM, including unlimited authorization, double dip issue, reentrancy attack, etc

  * UTXO style `fine-grained execution model` reduces risk-free arbitrage

* `Front-running mitigation` through random execution of transactions (see code, wiki to come)

* PoLW algorithm reduces the energy consumption of PoW in the long term ([research paper](https://github.com/alephium/research/blob/master/polw.pdf))

  * Adaptive rewards based on hashrate and timestamp are designed and implemented

  * Internal mining cost through burning will be activated when hashrate and energy consumption is significantly high
