Kusama and Polkadot are independent, standalone networks built on very similar codebases, but Kusama has faster governance parameters and lower barriers to entry. While Kusama is wild and fast, Polkadot is more conservative, prioritizing stability and dependability, with slower, more methodical governance and upgrade processes. Kusama is great for bold experimentation and early-stage deployment. Polkadot is designed for stable execution of risk-averse, high-value applications.

As the launch of Polkadot draws near, many are asking how the network will compare to Kusama and how both will be used in different ways going forward. Below we’ll explore a few of the key…

To close out the year, we asked colleagues colleagues working on the launch of Polkadot 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.

Responses come from almost every team at Web3 Foundation — from the Research and Communications to Infrastructure and Community & Growth — and from three continents. We also asked a few colleagues at our main development partner Parity Technologies to join in.

Enjoy! And see you in 2020.

The KILT Protocol team launched their first test net, “Mash-Net,” built on Parity Substrate. The open-source blockchain protocol enables trust markets through verifiable certificates and the integration of data sovereignty. KILT intends to secure a parachain slot after Polkadot main net launch and aims to provide the Polkadot ecosystem with an interoperable trust infrastructure to create numerous opportunities for both projects.

KILT Protocol has the potential to be an essential building block of Web 3.0: It allows users (persons, organizations, objects, artificial intelligence) to claim arbitrary attributes about themselves in a standardized way and receive attestation from trusted entities.

The…

Web3 Foundation engaged Chain Security for an audit of the Polkadot Claims smart contract. The audit found 0 Critical, 0 High, 2 Medium and 9 Low level issues, all of which have been resolved in the latest commits to the code.

The Polkadot Claims contract is an Ethereum smart contract allows holders of the DOT allocation indicator token to claim their balances of DOTs to a Polkadot public key ahead of Polkadot genesis.

In order to launch Polkadot in a transparent and decentralized way, an Ethereum smart contract was required to hold data necessary to the genesis of Polkadot including…

Kusama is an experimental community research and development network.

Warning: this is an experimental network.

EXPECT CHAOS.

In Kusama’s mind, “R&D” stands for Risk and Danger. Introducing Polkadot’s wild cousin, its canary in the coal mine: the Kusama network.

Kusama is an early, unaudited and unrefined release of Polkadot. Kusama will serve as a proving ground, allowing teams and developers to build and deploy a parachain or try out Polkadot’s governance, staking, nomination and validation functionality in a real environment.

Kusama is a canary-net: It is an early, highly experimental version of Polkadot presenting real economic conditions. It is not…

Note: Everything described here is subject to change before Polkadot’s initial mainnet launch, which is targeted for the end of 2019 depending on security audits and launch provisions outside of our control. It is also very likely that once Polkadot goes live, the network will upgrade the governance mechanisms described here. To stay up-to-date, follow Polkadot on Twitter for future announcements or keep an eye on the Polkadot Wiki, where the details of the governance mechanisms will be updated

Polkadot institutes a cutting-edge governance model designed to achieve a healthy network that adapts to its users’ needs. It is designed…

The Akropolis team launched a Substrate-based chain earlier this year for their DeFi protocol. Akropolis intends to participate in a parachain slot auction after the Polkadot main net launch. As a parachain, they would provide financial services and contracts to other applications in the Polkadot system.

Once launched, the Akropolis chain will enable peer-to-peer, user-owned financial organizations to exchange value regardless of geography and provide core financial services without dependending on banks, governments, or financial institutions (e.g. savings accounts, pooled financial/investment instruments, pooled insurance contracts, alternative pensions solutions, etc.). …

The Polkadot and Web3 community has grown significantly in 2019, with community events taking place around the world. We want to encourage these events and help facilitate them, so together, we can grow the global Web3 community.

Staying true to our vision of a distributed web & community, our team is here to encourage and help facilitate independently-hosted events wherever you are in the world. We have supported many events across Europe, Asia, North America, and are looking for your support to help grow the Polkadot and Web3 community worldwide.

Past events have been successfully organized across Asia, North America…

If you follow the developments of the larger ecosystem closely, then you already know that Polkadot represents an exciting part of where Web3 is headed. Since 2016, when Dr. Gavin Wood wrote Polkadot’s whitepaper, we’ve been working to connect private/consortium chains, public/permission-less networks, oracles and future technological developments yet to be created in the Web3 ecosystem. Today marks the day that we turn outward to ask for your help with this mission by launching the official Polkadot Ambassadors Program.

We already know that you’re out there. Every day, we interact with scores of Polkadot enthusiasts around the globe, who understand…

As Polkadot gets closer to mainnet launch, the Web3 Foundation is increasingly receiving inquiries about parachains: the initial allocation and the steps a project takes to become a parachain. The following is a working document that includes a draft plan for a fair parachain distribution at launch as well as an explanation of how Polkadot will handle additional parachain slot availability in the future.

We have sent an earlier version of this document to a number of projects building on Polkadot and we are now offering it to the greater Polkadot community to elicit feedback from additional parachain builders and…
