Polygon

Polygon, previously known as Matic Network, is a Layer 2 scaling solution backed by Binance and Coinbase. Key features include scalability, security, and the ability to create sovereign blockchains with the flexibility and independence of standalone blockchains but with the security and interoperability of Ethereum. It provides an infrastructure for building Ethereum-compatible and interoperable blockchain networks.

Polygon uses a version of the PoS (Proof of Stake) consensus algorithm in its mainnet. It also uses an architecture known as Heimdall and Bor. Heimdall is the Proof of Stake layer where validators stake POL tokens to secure the network, and Bor is the block producer layer which uses a set of validators elected by PoS participants.

Operating a dedicated Polygon PoS node demands technical proficiency, a reliable and stable internet connection, and sufficient hardware resources. Hosting a dedicated node contributes significantly to the network's decentralization, security, and overall integrity. Serving as a validator within the PoS consensus mechanism enables you to garner rewards from transaction fees and staking activities.

Polygon offers a variety of SDKs and developer tools such as:

• Javascript
• GO
• Swift.
• Developers can utilize the Polygon SDK, which supports stand-alone chains and secured chains. It's designed for flexibility and allows developers to build both Layer 2 chains or standalone chains. Other tools include Remix, Truffle, Hardhat and the Matic.js library which facilitate easier integration with the Polygon network.

Yes, the native token of the Polygon network is POL. The POL token is used for various purposes in the Polygon ecosystem, such as participating in the network's PoS consensus mechanism, paying gas fees, and contributing to on-chain governance.
