# 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. --- # Agent Instructions: 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.
