SRTOOL & Deterministic builds are back to Kusama & Polkadot

Deterministic builds are back, srtool is now usable again in order to build and verifiy Substrate and Polkadot WASM blobs used as runtime.

Registrars updates

Since its first implementation around the end of 2019, the `Registrar #1` (which is now a set of registrars), has evolved a lot. This article looks back on those evolutions as well as at the current stand. I will go through the challenges I ran into and how they have been solved. This includes a few dedicated web services, the use of a BPM engine as well as new functionnalities recently added to Polkadot, Kusama and the Westend chains.

Docker for Polkadot & Decentralization

Docker is a powerful virtualization tool. While this is not the only virtualization solution available today, it remains one of the simplest to use. Let's see if and how it plays a critical role in decentralized systems.

The Brave browser and what you missed

Google Chrome needs no introduction and most people who visited an internet page within the last 5 years likely used Chrome or one of the Chromium based browsers. Figure 1. Chrome Market Share since 2013 Chrome is the browser developed and maintained by Google and it is a great browser. Chrome brought speed to the internet, a fast and slick interface, themes, extensions, excellent Javascript support, great tools for developers.

Kusama Proposal: New Registrar

At the launch of the Kusama network, there was no way to identify who the owner of a given account was beside making your own research and adding a name to an account in the https://polkadot.js.org/apps/#/addressbook[PolkadotJS UI]. New solutions have been tested and the system is evolving.
