Kusama Identity Registrar #1 - Why and How?

In a previous article, I submitted a motion to the Kusama Council proposing the registration of a new registrar on Kusama: Registrar #1. Unlike the name suggests, this is not the first registrar on Kusama. It brings a second registrar on the chain as we can see by querying the chain state of the identity module: 1. TLDR If you only want to jump to practical todos ignore the explanations, you may directly go to Certification process.

srtool now showing Substrate proposal hashes

I introduced srtool in a previous article. While the first implementation filled a gap and allowed for the first time users to verify substrate runtime wasm blobs, there was still work to do to improve the user’s experience. 1. Current verification process Up to now, the verification process looked like: a runtime dev works on some changes he builds the new runtime locally, preferably using srtool in order to get the SHA256 of the new wasm blob right away

Brave Crypto Wallet powered by Metamask

The surprise You may read more about Brave in my first article about the Brave browser. After recently visiting one of my own blog post to check the spelling, I got the surprise to be welcomed by a pop proposing me to install a mysterious Crypto Wallet extension.

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.

Cargo Remote: Speed up your Rust builds

There is no question that Rust is one of the, if not THE, best language of the decade. Rust allows us writting safe code while doing most of the safety checks at compile time. That means that we no longer need to bloat the binary that is produced with extra checks to safeguard against developer mistakes such as null and dangling pointers or overflows to mention just a few.
