 Ethereum developers are by default Polygon developers. Welcome. Simply switch to the [Polygon RPC](https://polygon-rpc.com/) and get started. All familiar tools used on Ethereum are supported on Polygon. Whether it is Truffle, Remix or Web3js, Polygon offers the same UX as Ethereum.

 ## Overview
 
 Polygon is a layer 2 (L2) network to Ethereum, employing a proof-of-stake (PoS) consensus mechanism, and thus composed of the following two layers:

+ Welcome to the Polygon PoS how-to section. There is a number of how-to guides here to help you get started with common technical tasks. We hope you find them useful.
 
 The section covers a number of tutorials on how to operate different types of Polygon PoS nodes, how to bridge assets from PoS to Ethereum and conversely, or send messages between L1 and L2 networks, and how to work with smart contracts.
 
-Included in the section is an elaborate startup guide for users who wish to implement the Polygon DID, which is a three-part package consisting of an indentity-registrar, an identity-resolver and an identity-registry-contract.

 The Polygon Proof-of-Stake (PoS) network, originally launched as Matic Network in June 2020, has been upgraded a number of times since inception. Initially designed to scale Ethereum through a sidechain, a new discussion on the Polygon forum proposes upgrading Polygon PoS into a zero-knowledge (ZK)-based validium on Ethereum.
