The Polkadot and Kusama ecosystems continue to evolve with key developments in governance, network upgrades, community initiatives, and upcoming events. From major protocol changes to global outreach efforts, here’s a comprehensive look at the latest happenings shaping the future of decentralized interoperability.
Sub0 Virtual Conference: A Must-Attend for Developers
Mark your calendars: Sub0, the premier virtual conference for Polkadot and Substrate developers, is set for October 13–14. This event will spotlight the latest advancements in Substrate, the foundational framework behind Polkadot’s modular blockchain design. Attendees can expect deep technical sessions, ecosystem project insights, and a special appearance by Gavin Wood, Polkadot’s co-founder and visionary architect.
Whether you're building on Polkadot or simply interested in the future of cross-chain communication, Sub0 offers invaluable knowledge and networking opportunities. Stay ahead of the curve by registering early and exploring the full agenda.

Gavin Wood Unveils XCM Fundamentals
In a significant move to improve developer understanding, Gavin Wood has launched a new article series introducing the Cross-Consensus Message Format (XCM). As the backbone of Polkadot’s interoperability model, XCM enables seamless communication between parachains and the relay chain.
The first installment breaks down:
- What XCM is and why it matters
- How messages are structured and executed
- Practical use cases and implementation patterns
- Future evolution of the protocol
This educational resource is essential reading for developers aiming to build scalable, composable applications within the Polkadot ecosystem. By demystifying complex consensus mechanics, Wood is empowering builders to harness the full potential of cross-chain logic.
Polkadot Network Upgrades and Governance Updates
Runtime Upgrade via Referendum 33
Polkadot has successfully executed Referendum 33, upgrading its runtime to version 9090. This marks another milestone in the network’s continuous improvement cycle, enhancing performance, security, and governance efficiency. The upgrade was widely supported across the DOT holder community and reflects the strength of Polkadot’s decentralized decision-making process.
Council Approves Funding for Polkadot Research Institute
The Polkadot Council has passed Motion 107, allocating treasury funds to support the Polkadot Ecosystem Research Institute. This initiative aims to advance core protocol research, foster academic collaboration, and publish technical papers that guide long-term network development.
Spanish-Language Education Initiative Launched
Two official Polkadot Ambassadors have announced plans to create a Spanish-language education center, expanding access to Web3 knowledge in Latin America and Spanish-speaking regions. This effort aligns with Polkadot’s mission of global inclusivity and aims to onboard new developers and users through localized content and training programs.
Validator Set Expansion Fails
A proposal to increase the number of active validators from 297 to 299 (Referendum 32) has failed as voting concluded. Although substantial DOT support was present, the motion did not meet the required threshold under Polkadot’s adaptive quorum biasing mechanism, which demands stronger majorities for proposals originating from public referenda.
This outcome highlights the robustness of Polkadot’s governance model—designed to prevent rapid or contentious changes without broad consensus.
Kusama Network Developments
Sixth Parachain Slot Auction Concluded
On September 8, Kusama completed its sixth parachain slot auction, with KILT Protocol emerging victorious after securing 219,999.9 KSM in crowdloan contributions. KILT officially connected to the Kusama relay chain later that day, beginning block production as a fully operational parachain.
PolkaWorld conducted an exclusive interview with the KILT team, discussing their vision for decentralized identity and how they plan to leverage Kusama’s canary network environment for rapid innovation.
Seventh Auction Underway
Immediately following the sixth auction, the Kusama Council passed Motion 350, launching the seventh parachain slot auction. Current leaders include:
- Calamari (Manta Network’s canary chain) – 216,042 KSM
- Basilisk – 156,345 KSM
- Altair (Centrifuge) – 54,861 KSM
- Heiko (Parallel Finance) – 38,143 KSM
These projects represent diverse use cases—from DeFi and NFTs to asset tokenization—showcasing Kusama’s role as a high-risk, high-reward innovation lab for Polkadot.

Treasury-Funded Integrations Moving Forward
Kusama continues to strengthen its ecosystem infrastructure through strategic treasury allocations:
- Motion 277: Integration with DeepDAO is now complete, enabling better governance analytics and transparency.
- Motion 349: Funding approved to integrate Statemine (Kusama’s common good parachain) into the Kodadot NFT marketplace UI, improving accessibility for creators and collectors.
RPC Services Proposal Under Review
The council is currently evaluating a proposal from Dwellir to develop enhanced RPC services for Kusama. Reliable remote procedure call endpoints are critical for developer tooling, wallet integrations, and node operation—making this a high-impact infrastructure upgrade.
Failed Referendum Attempts
- Referendum 133, aimed at reversing the effects of Referendum 129, failed due to insufficient support. Referendum 129 had inadvertently reduced the
ump_service_total_weightparameter from 100 billion to 5 billion, affecting message processing capacity. - Despite Bifrost’s efforts to correct this via Referendum 133, the reversal did not gain enough traction among voters.
Successful HRMP Parameter Adjustment
Referendum 132 passed and was implemented, increasing the HRMP (Horizontal Relay-routed Message Passing) open request time-to-live (TTL) from 2 sessions to 72 sessions. This change provides parachain teams with significantly more flexibility when establishing cross-chain communication channels. The technical committee accelerated this proposal due to its urgent operational importance.

Frequently Asked Questions (FAQ)
What is Sub0 and who should attend?
Sub0 is a virtual developer conference focused on Substrate and Polkadot technologies. It's ideal for blockchain engineers, protocol researchers, and anyone building decentralized applications on the Polkadot stack.
Why did Referendum 32 fail despite strong DOT support?
Polkadot uses adaptive quorum biasing for public referenda, requiring supermajorities for passage. Even with high stake support, Referendum 32 didn’t meet the elevated threshold needed for approval.
How does XCM enable cross-chain communication?
XCM is a messaging format that allows parachains to send instructions and data across the relay chain. It supports trustless interaction, enabling features like asset transfers, remote execution, and shared logic between chains.
What’s the difference between Polkadot and Kusama?
Kusama is Polkadot’s “canary network”—a faster, less governed environment for testing new features and projects before deployment on Polkadot’s mainnet.
Can anyone participate in parachain auctions?
Yes. Token holders can contribute to crowdloans for their favorite projects, potentially earning rewards if the project wins a slot. Participation helps decentralize network development.
Is there a Spanish-language learning path for Polkadot?
Yes. A new education initiative led by Polkadot Ambassadors aims to deliver comprehensive Web3 content in Spanish, lowering entry barriers for Latin American developers and users.
