The Polkadot and Kusama ecosystems continue to evolve at a rapid pace, with key upgrades, governance decisions, and network developments shaping the future of decentralized infrastructure. This week’s update highlights essential technical upgrades, upcoming milestones in parachain auctions, and active community governance proposals—all crucial for developers, validators, and ecosystem participants to stay informed.
Polkadot 0.9.11 Released: Critical Upgrade for Node Operators
The latest release of Polkadot 0.9.11 has been rolled out with a medium-priority upgrade classification. This version introduces an important database migration, which means that reverting to version 0.9.10 without a full chain resynchronization is no longer possible. This change emphasizes the importance of timely node maintenance and forward compatibility within the network.
All node operators—on both Polkadot and Kusama—are strongly advised to upgrade their nodes to at least version 0.9.10 by October 11. Failure to do so will result in incompatibility after the upcoming runtime v9100 upgrade, leaving outdated nodes unable to sync with the network.
This upgrade is not just a routine maintenance step; it ensures seamless continuity during runtime transitions and supports long-term network stability. Validators and infrastructure providers should treat this as a high-priority task to avoid service disruptions.

Sub0 Conference Kicks Off: A Milestone for Substrate Developers
Next week marks the highly anticipated Sub0 conference, taking place on October 13–14, dedicated entirely to Substrate development. As the largest gathering of Substrate builders, Sub0 offers sessions tailored for developers across all experience levels—beginner, intermediate, and advanced.
Attendees can expect deep dives into core Substrate architecture, best practices for pallet development, runtime customization, and insights into building scalable parachains. With Polkadot’s ecosystem growing rapidly, events like Sub0 play a vital role in fostering technical excellence and community collaboration.
Whether you're building your first custom chain or optimizing an existing parachain, Sub0 provides valuable networking opportunities and direct access to core developers from Parity Technologies and beyond.
Polkadot Referendum #35: Lack of Detail Sparks Concern
A new governance proposal—Polkadot Referendum #35—has raised eyebrows due to its lack of transparency. The referendum proposes changes to the runtime code, but curiously, it includes no additional context or explanation beyond the inclusion of the Wasmblob itself.
This absence of documentation has led to skepticism among voters, and as of now, the proposal appears to be heading toward failure in the voting process. In a decentralized ecosystem where informed decision-making is paramount, such opaque submissions risk undermining trust in the governance system.
The incident underscores the need for clearer communication standards in future proposals. Community members are calling for mandatory explanatory notes and impact assessments before runtime changes are submitted for voting.
Heiko Secures Kusama’s 10th Parachain Slot
On October 6 at 16:50 UTC, Kusama concluded its 10th parachain slot auction. After approximately 40 minutes of the randomized "candle auction" mechanism—colloquially known as “rolling the dice”—Heiko, the canary network of Parallel Finance, emerged victorious.
Heiko secured the slot by locking 202,793 KSM, demonstrating strong community support and strategic crowdloan participation. Just two hours later, at around 18:30 UTC, Heiko successfully connected to the Kusama relay chain and began producing blocks as a fully operational parachain.
This milestone enables Heiko to test new DeFi primitives in a live environment, including lending, staking derivatives, and cross-chain asset integration—paving the way for Parallel Finance’s mainnet deployment on Polkadot.
Kusama’s 11th Auction Underway: KintsugiBTC Leads the Race
The countdown has begun for Kusama’s 11th parachain auction, which officially launched at block #9,535,569. The auction is expected to conclude around October 13 at 14:30 UTC.
Currently leading the bid is KintsugiBTC, the canary network of Interlay’s Bitcoin-wrapping solution. It has reached its crowdloan cap of 199,999.9 KSM, indicating robust community backing and demand for native Bitcoin interoperability within the Kusama ecosystem.
KintsugiBTC aims to bring cross-chain BTC functionality to Kusama, allowing users to use Bitcoin in DeFi applications through trust-minimized wrapped BTC (kBTC). If successful, this integration could significantly expand Kusama’s utility in the multi-chain landscape.
Other contenders are still active in secondary markets, but with KintsugiBTC hitting its maximum target, momentum appears firmly in its favor.

Governance Acceleration: Runtime Upgrades Fast-Tracked
Two critical runtime upgrades for Kusama have been fast-tracked by the Technical Committee, reflecting urgent technical needs within the network:
- Referendum #135: Proposes upgrading Kusama’s runtime to v9100
- Referendum #136: Proposes upgrading Kusama’s runtime to v9110
Both proposals are now open for voting by all KSM holders, emphasizing the decentralized nature of governance in the Kusama network. These upgrades are designed to improve performance, fix bugs, and ensure compatibility with new features being rolled out across parachains.
Fast-tracking these referendums highlights the agility of Kusama’s governance model—enabling rapid responses to evolving technical requirements while maintaining community oversight.
Statescan Seeks Treasury Funding for Enhanced Tooling
Statescan, a popular Substrate-based blockchain explorer, has submitted a funding request to the Kusama Treasury. The proposal aims to enhance its asset chain browser capabilities, providing better visualization and analytics for token holders, developers, and auditors.
If approved, the upgrade will offer improved support for:
- Multi-chain asset tracking
- Real-time balance monitoring
- Historical state queries
- User-friendly transaction decoding
This initiative aligns with broader efforts to improve developer tooling and user experience across the Polkadot ecosystem. Treasury-funded projects like this demonstrate how decentralized funding can drive innovation without centralized control.
The proposal is currently awaiting feedback from both the Kusama Council and the wider community.
Frequently Asked Questions (FAQ)
What is a parachain slot auction on Kusama?
A parachain slot auction allows projects to lease a slot on Kusama’s relay chain for a fixed period (typically up to 48 weeks). Projects raise KSM through crowdloans, where supporters contribute tokens in exchange for future rewards or project benefits.
Why is Polkadot 0.9.11 important for node operators?
Version 0.9.11 includes a database migration that prevents rollback to previous versions without resyncing. Node operators must upgrade by October 11 to remain compatible after the v9100 runtime upgrade.
What happens if a node doesn’t upgrade before the runtime change?
Nodes running outdated software will fail to sync with the network, leading to missed blocks, reduced validator performance, or complete disconnection from the chain.
How does the “candle auction” work in Kusama?
The candle auction uses a random endpoint within a predefined window to determine the winner, preventing last-second bidding manipulation. It adds fairness and unpredictability to the parachain slot allocation process.
What is the difference between Polkadot and Kusama?
Kusama is Polkadot’s canary network—faster-paced and less formal—used for testing new features and innovations before deployment on Polkadot. It serves as a proving ground for teams building on Substrate.
Can anyone vote on Kusama referendums?
Yes, any holder of KSM tokens can participate in governance by voting on referendums. Voting power is proportional to token holdings and lock-up duration.
Final Thoughts: Momentum Builds Across Both Networks
As Kusama approaches the end of its 11th parachain auction and Polkadot prepares for critical runtime upgrades, both networks showcase the strength of decentralized governance and continuous innovation.
From developer conferences like Sub0 to treasury-backed tooling improvements and high-stakes parachain competitions, the ecosystem remains dynamic and community-driven. These developments lay the groundwork for broader adoption, enhanced security, and richer cross-chain applications in 2025 and beyond.
For developers, investors, and enthusiasts alike, staying engaged with these updates is essential—not just to follow trends, but to actively shape the future of Web3 infrastructure.
