New version of PolkaStats

PolkaStats is a Substrate open source block explorer aiming to provide the best staking and economic data for both validators and nominators. It helps both types of users by providing comprehensive metrics, charts and utilities to improve their knowledge and performance.

The project needed a big refactor for a long time so I finally decided to migrate the backend to TypeScript to take full advantage of type’s magic delivered by Polkadot JS API and increase code robustness.

Lot of work was spent in the frontend also with the focus on removing legacy code that didn’t work and creating some new solid features that leveraged the new backend.

Most important thing about this version of PolkaStats is that Validator Resource Center for Kusama features has been completely ported to PolkaStats block explorer. The reason behind this is that it is difficult for me to maintain these two projects at the same time. Now you can filter and select validators based on your preferences and the provided metrics. Once you are done, you can even submit your selection to the chain using Polkadot JS Extension.

I’ll show you some of the most relevant changes:
