Kusama’s First Adventure
A little chaos ensued on the Kusama network, Polkadot’s canary-net. Here’s a quick summary of the cause and solution.
Polkadot 2019: Year in review
I started the last year-end round-up with some statistics, and it seems fitting to continue the trend and report some numbers from this year. In total, the Polkadot project, including Substrate, Grandpa, Cumulus and a few bits of support code, has over three hundred thousand lines of code!
Goodbye 2019, Hello 2020
To close out the year, we asked colleagues across the Polkadot Launch Team to reflect on their work in 2019 and discuss what part of their work they’re most looking forward to in 2020. We’re excited to share their answers (some serious and some light-hearted!) with you below.
Polkadot Consensus Part 4: Security
So far, we have discussed how BABE creates blockchain candidates and GRANDPA finalizes them. We know that we need more than two-thirds of validators to properly follow the protocol. But how many validators are there? How are they chosen? Why should they follow the rules?
Polkadot Consensus Part 3: BABE
Blind Assignment for Blockchain Extension (BABE) is a block production engine that was inspired by Ouroboros Praos, another proof-of-stake protocol. It can be used on its own because it provides probabilistic finality, or it can be coupled with a finality gadget like GRANDPA.
Polkadot Consensus Part 2: GRANDPA
In the introduction to this series, I outlined that a consensus algorithm helps a network of computers answer three questions. GRANDPA addresses the second.
Polkadot Consensus Part 1: Introduction
This series will be a discussion about security and consensus in Polkadot. In part 1, we will define some terms before getting into the details of how Polkadot creates and secures blocks.
