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.

San Francisco and Zug — Web3 Foundation and Polychain Capital are joining forces to launch the Polkadot Ecosystem Fund during San Francisco Blockchain Week. The fund is a Polychain-operated investment vehicle jointly capitalized by Web3 Foundation and Polychain.
Kusama CC2: PrePoS
Kusama just got an upgrade. I’m pleased to announce that at exactly 9am today (Zug time), Kusama CC-2 went through a full upgrade to runtime version 1005 as found in Polkadot release v0.6.3.
Kusama CC2
Three weeks ago, we released Kusama Chain Candidate 1 (CC1). After several key fixes to the Polkadot, including the Babe consensus layer, we’re pleased to release the next chapter in Kusama: CC2.
