$CFX CFX can refer to a few different things, but in the context of cryptocurrency, it most commonly refers to Conflux.

Conflux is a public, permissionless Layer-1 blockchain platform. Here's a quick overview:

* Technology: It uses a unique "Tree-Graph" consensus algorithm, which combines elements of Proof of Work (PoW) and a Directed Acyclic Graph (DAG) to achieve high transaction throughput and scalability. It's designed to process multiple blocks simultaneously, which sets it apart from traditional blockchains like Bitcoin.

* Token: The native cryptocurrency of the Conflux network is also called CFX. It's used for network governance, staking, paying transaction fees, and interacting with decentralized applications (DApps) on the platform.

* Features: Conflux is compatible with the Ethereum Virtual Machine (EVM), which makes it easier for developers to migrate their DApps from Ethereum or build new ones. It also aims to provide low transaction costs and a "Fee Sponsorship Mechanism" that allows users with no CFX to still interact with the network.

While "CFX" is most associated with the Conflux cryptocurrency, it's worth noting that it's also the name of a licensed crypto exchange in Indonesia, PT Central Finansial X.
