Chia is a modern cryptocurrency built from scratch, designed to be efficient, decentralized, and secure. Here are some of the features and benefits:
2021-03-23 20:40:19 +03:00
* [Proof of space and time ](https://docs.google.com/document/d/1tmRIb7lgi4QfKkNaxuKOBHRmwbVlGL4f7EsBDr_5xZE/edit ) based consensus which allows anyone to farm with commodity hardware
* Very easy to use full node and farmer GUI and cli (thousands of nodes active on mainnet)
2021-05-26 21:11:44 +03:00
* Simplified UTXO based transaction model, with small on-chain state
* Lisp-style Turing-complete functional [programming language ](https://chialisp.com/ ) for money related use cases
2021-03-23 20:40:19 +03:00
* BLS keys and aggregate signatures (only one signature per block)
* [Pooling protocol ](https://www.chia.net/2020/11/10/pools-in-chia.html ) (in development) that allows farmers to have control of making blocks
* Support for light clients with fast, objective syncing
2021-05-12 23:12:30 +03:00
* A growing community of farmers and developers around the world

Python 3.7+ is required. Make sure your default python version is >=3.7
by typing `python3` .
If you are behind a NAT, it can be difficult for peers outside your subnet to
reach you when they start up. You can enable
[UPnP ](https://www.homenethowto.com/ports-and-nat/upnp-automatic-port-forward/ )
on your router or add a NAT (for IPv4 but not IPv6) and firewall rules to allow
TCP port 8444 access to your peer.

These methods tend to be router make/model specific.

Most users should only install harvesters, farmers, plotter, full nodes, and wallets.
Building Timelords and VDFs is for sophisticated users, in most environments.
2020-04-27 02:18:21 +03:00
Chia Network and additional volunteers are running sufficient Timelords
2021-03-14 01:57:41 +03:00
for consensus.
