# Radix Mainnet (Olympia)

**[Olympia](https://www.radixdlt.com/blog/radix-olympia-launch)** [ /oʊˈlɪmpiə/ ] was was the initial release of the Radix Public Network and introduced the core node software, desktop wallet, staking, the Radix Explorer, and the native $XRD token. [Olympia](https://learn.radixdlt.com/article/what-was-radixs-olympia-mainnet) did not employ the [Radix Engine](/contents/tech/core-protocols/radix-engine) as a runtime environment for decentralized applications.

## Etymology

All Radix public releases are related to the [Seven Wonders of the Ancient World](https://en.wikipedia.org/wiki/Seven_Wonders_of_the_Ancient_World). Olympia was the location of the [Statue of Zeus](https://en.wikipedia.org/wiki/Statue_of_Zeus_at_Olympia).

## Release Components

The Olympia release provided the core components of the Radix ecosystem, which continued to expand with future releases. Key components included:

### Radix Node software

Implemented the core Radix protocol, including [Radix Engine](/contents/tech/core-protocols/radix-engine) v1 and unsharded [Cerberus](/contents/tech/core-protocols/cerberus-consensus-protocol) consensus.

### The [Radix Engine](/developers/legacy-docs/reference/radix-engine/radix-engine)

The first version of Radix's replacement for the [Ethereum](https://ethereum.org) Virtual Machine, designed to eventually run full [DeFi](https://en.wikipedia.org/wiki/Decentralized_finance) applications.

### RADIX token - $XRD

The native [$XRD](/contents/tech/core-protocols/xrd-token) token, used for staking, network security, and transaction fees.

### Simple Token Creation

Allowed new tokens to be created, named, minted, burned, and transacted via the JSON-RPC Radix Node API.
