The Polkadot and Kusama ecosystems continue to gain momentum, with major upgrades, parachain auctions, and community-driven governance shaping the future of decentralized networks. This week’s update highlights critical developments across both platforms—from parachain onboarding and staking improvements to governance milestones and upcoming events celebrating Web3 innovation.
Polkadot: Fourth Parachain Slot Secured, Fifth Auction Underway
On December 9, 2021, at 20:52 UTC, Polkadot concluded its fourth parachain slot auction. The candle auction mechanism ended in the randomized termination phase, with Parallel emerging as the winner after successfully locking 10,751,500 DOT.
With this win, a total of four projects have now secured parachain slots on Polkadot. Combined with active and completed crowdloans, over 108 million DOT—representing 9.2% of the total supply—have been committed to support these decentralized projects.
The fifth auction launched shortly after, on December 10 at 02:51 UTC. Among the current crowdloan campaigns, Clover leads in DOT contributions, followed by strong contenders such as Efinity, Manta, and Litentry.
A significant milestone is approaching: all five initial parachain winners will go live on the Polkadot relay chain around 04:00 UTC on December 18, 2021. At that moment, they will begin producing blocks as fully operational parachains—marking a pivotal step in Polkadot’s journey toward scalable, interoperable blockchain solutions.
Celebrating a New Era: Polkadot Parachain Party
To commemorate this historic launch, the Polkadot team will host a virtual event called the Polkadot Parachain Party on December 19 via Twitter Spaces. This live broadcast will celebrate the network’s evolution and engage the global community in discussions about the future of decentralized applications.
Additionally, Polkadot has launched a creative contest under the hashtag #AdsForChads, inviting users to design fictional commercials for their favorite parachains. Winners will receive exclusive Polkadot merchandise and recognition during the event. It’s a fun way to boost engagement while showcasing the ecosystem’s vibrant culture.
Governance Upgrade: Validator Count Increased
Polkadot’s Referendum #43 has passed, approving an increase in the maximum number of active validators from the previous cap to 400. This enhancement improves network decentralization and security by allowing more participants to contribute to consensus.
The upgrade reflects Polkadot’s commitment to on-chain governance—where stakeholders directly influence protocol changes through democratic voting. As validator diversity grows, so does the network’s resilience against centralization risks.
Kusama: 18 Parachains Live, 25.4% of KSM Locked
Kusama, Polkadot’s canary network, continues to lead in innovation and rapid deployment. The 17th parachain auction concluded on December 12 at approximately 12:00 UTC, with Zeitgeist securing the slot by bonding 77,028 KSM. Shortly after, the 18th auction began, with Sakura currently leading in bids.
With these additions, a total of 18 parachains are now integrated into the Kusama relay chain—including Statemine, the network’s system parachain for asset issuance. Collectively, these projects have locked 2,995,000 KSM, representing 25.4% of the total circulating supply—a strong signal of community confidence and economic participation.
Key Kusama Upgrades and Proposals
- Referendum #158 passed, approving Encointer as a公益 (public good) parachain. It is scheduled to go live around 05:00 UTC on December 17.
- Referendum #160 succeeded, upgrading Kusama to runtime version v9130, enabling new features and performance optimizations.
- A proposal has been submitted by Acala to establish an HRMP (Horizontal Relay-routed Message Passing) channel between Karura and Statemine, facilitating cross-chain communication. The proposal is currently under review by the Kusama Council and community.
These developments underscore Kusama’s role as a high-speed testing ground for innovations later deployed on Polkadot.

Frequently Asked Questions
What is a parachain auction?
A parachain auction allows projects to lease a slot on Polkadot or Kusama’s relay chain by gathering community support through crowdloans. Winners gain access to shared security and cross-chain capabilities for a fixed period.
Why is 25.4% of KSM locked significant?
High token lockup indicates strong ecosystem engagement. With over a quarter of KSM staked in parachain bids, it reflects confidence in Kusama’s utility and long-term value.
How does increasing validators to 400 improve Polkadot?
More validators enhance decentralization, reduce concentration risks, and strengthen network security by distributing consensus power across a broader set of nodes.
What happens when a parachain goes live?
Once connected, a parachain can process transactions independently while benefiting from the relay chain’s security and communicating with other chains via XCMP (Cross-Chain Message Passing).
What is HRMP, and why does it matter?
HRMP (Horizontal Relay-routed Message Passing) enables temporary message transfer between parachains before full XCMP is implemented. It's essential for early-stage interoperability.
How can I participate in future auctions?
Users can support projects by contributing DOT or KSM to crowdloans. In return, they often receive project-specific rewards or governance tokens.
This week marks a turning point for both Polkadot and Kusama. With multiple parachains live, governance evolving, and developer momentum building, the foundation for a scalable Web3 future is firmly in place. As these networks mature, they continue to demonstrate the power of community-driven innovation in decentralized systems.
