Polygon PoS Architecture Explainer

Polygon PoS Architecture Explainer (Under the section blockchain and cryptocurrencies)

Description

Polygon (just incase you never heard that name xD) is stack of blockchain protocols designed to solve scalability issues for public blockchains, specifically ethereum. One of the primary and early solutions of Polygon is it's Proof of Stake (PoS) chain which runs as a side chain to ethereum. It's one of the most used side chain with more than 19k+ decentralized applications deployed on it. Lot of developers have chosen to deploy on Polygon PoS chain as it's much cheaper and faster as compared to other solutions.

Now, as a developer, there is literally no difference in building stuff (be it contracts or dapps) on Polygon. The user experience and efforts are same as that on ethereum or any EVM compatible chain. So, given the large number of users and developers, it's interesting for them to know the underlying architecture of the chain and all the components involved in it. I would say the components are developed in such a fashion that they abstract lot of things from the end user.

In my current role at Polygon, working as a blockchain developer on the PoS chain itself, I've been involved in knowing the internals of the system. This will help me explain the major components of the system and some lesser known stuff about the chain. It can be a good introduction of Polygon to some beginner and will help those who already know/have developed on the chain in a better way.

About me: I work at Polygon (Prev. Matic Network) as a Blockchain Developer, specifically on it's PoS chain (bor and heimdall). While I am away from work, I love to explore blockchain protocols and take part in hackathons. You can find more details about me at my website.
