## What it is
The reference node implementation of the æternity blockchain, a scalable public blockchain platform written in Erlang. It supports smart contracts, state channels, oracles, a naming system, and tokens, and can be run via installer packages or Docker.

## Use cases
- run an aeternity blockchain node
- mine aeternity coins
- deploy and execute smart contracts on aeternity
- sync the aeternity mainnet or testnet from a snapshot
- operate a node in docker for blockchain development
- build decentralized apps on the aeternity platform
- run a hyperchain sidechain secured by bitcoin PoW

## When to choose
- you need to operate or participate in the æternity network as a miner or node operator
- you are building dapps or smart contracts targeting the æternity protocol
- you want a blockchain with state channels for high-throughput off-chain transactions

## When to avoid
- you need a general-purpose blockchain framework to build your own chain from scratch
- you want Ethereum or EVM compatibility
- you are not working with the æternity ecosystem specifically

## Facets
- artifact type: application
- maturity: active
- function: cryptography, networking, cli, developer-tools
- domain: blockchain, microservices, security
- platform: windows, elixir
- tags: blockchain-node, smart-contracts, state-channels, oracles, naming-system, erlang, cryptocurrency, hyperchains, proof-of-work, linux, macos, docker
