Deterministic builds are back, srtool is now usable again in order to build and verifiy Substrate and Polkadot WASM blobs used as runtime.
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.
While using a website such as https://polkadot.js.org/apps/#/ or the https://github.com/polkadot-js/extension are convenient, those do not provide the best internet isolation to ensure the maximum security for your keys. This article explains how to use subkey to sign challenges for `Registar #1`.

Keeping an eye on the Polkadot network with Polkabot. Polkabot sends network alerts related to the Polkadot network.
Wilfried Kopp, aka Chevdor, talks about Substrate and Polkadot, as well as his work with KI decentralized, a blockchain consultancy, and Polkabot, a chat-bot for monitoring the Polkadot network.
Substrate & Polkadot are new Blockchain technologies programmed in a rather new but ultra safe language called Rust. This article helps you get started with a full network running locally, without requiring any prio Rust knowledge.
