# Blockchain Technology

## DOS Chain

We decided to develop an [Avalanche L1](https://docs.avax.network/learn/avalanche/subnets-overview), named [DOS Chain](https://doschain.com/), due to its usability, accessibility, and security features. [DOS Chain](https://doschain.com/) enables MetaDOS to provide best-in-class performance with its unique subnet architecture, innovative Snowman consensus, and unparalleled safety guarantees. 

DOS also stands out among many blockchains due to its Net Zero carbon footprint, reflecting our commitment to reducing environmental impact.

With DOS’s sub one-second settlement time and [**zero** transaction fees](https://docs.doschain.com/#ko5fk), we can ensure a great user experience across our platform. DOS is designed to ensure outstanding performance while ensuring decentralization with reasonable hardware requirements for validators. 

## LayerZero

[LayerZero](https://layerzero.network/) technology allows players to effortlessly move their digital assets in and out of MetaDOS's platform with an advanced and secure cross-chain transfer technology.

## Openfort

With [Openfort](https://www.openfort.xyz/), we can combine the power of Web3 with the user experience of Web2 to easily onboard anyone with an email, Facebook, or Google account. Our Openfort-powered Web3 wallet, DOSafe, offers one-click login flows, flexible authentication options, and secure account recovery.

## Stardust

[Stardust](https://www.stardust.gg/) provides a straightforward REST API that offers the quickest and easiest way to onboard new players to our game, and manage their keys, and help create custodial wallets with a single API call.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.metados.com/intro/technology/blockchain-technology.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
