POLYGON

In our ambition to build the world’s largest NFT based game we quickly saw the need to choose an infrastructure that could support our immense ambitions, provide cost effective transactions and be fast enough to enable compelling gameplay. Finally, we wanted to build our Metaverse on a platform that shared our values concerning sustainability. After extensive research we settled on Polygon as the only L2 solution capable of meeting all of our stringent requirements. Polygon is incredibly cheap and quick to use and it is sufficiently decentralized. Perhaps most importantly, Polygon is one of the most environmentally friendly and sustainable blockchains in the market today. Polygon is a protocol and framework for building and connecting Ethereum EVM-compatible blockchain networks. It is a modular interoperability protocol which guarantees Ethereum’s deterministic finality on a much faster and scalable node network. Polygon combines the best of Ethereum into a much more agile developer experience. It uses the EVM’s established stack, tools, language and standards in a custom WASM execution environment, with a highly scalable consensus algorithm.

Polygon’s stability is provided by a pool of professional validators, with dedicated throughput and resources, with fully sovereign governance. Native support for arbitrary message passing, bridges to external systems and its instant transaction finality make it the perfect choice for a highly ambitious project like Planet IX - with mass adoption, upgradability and community collaboration in mind. Its compatibility with industry wide tools like MetaMask, Remix, Chainlink, and other existing ecosystem leaders further prove its trustworthiness and reliability. Polygon provides the core components and tools to join the global blockchain digital economy. Polygon architecture consists of four abstract, composable layers:

  1. Ethereum layer: Polygon uses Ethereum, the most secure programmable blockchain in the world, to host and execute mission-critical logic. Implemented in smart contracts these functions include staking, finality, disputes and messaging.

  2. Security layer: A set of validators that periodically check the validity of transactions and secure the network.

  3. Network layer: Responsible for block-production, local consensus and up time.

  4. Execution layer: The virtual machine implementation which runs execution and state transition.
