The countdown to Polkadot’s parachain slot auctions has begun, with Kusama—Polkadot’s canary network—already paving the way. As the ecosystem gears up for this pivotal phase, developers, investors, and blockchain enthusiasts are closely watching the progress, risks, and opportunities tied to one of the most anticipated upgrades in decentralized infrastructure.
In a recent AMA session hosted by Baihua Blockchain, Helena, Asia Business and Operations Lead at Parity Technologies, and Santry Huang, CMO of Patract Labs, provided deep insights into Polkadot’s development roadmap, the significance of WebAssembly (Wasm), and what the parachain auction means for the future of Web3.
The Role of Parity and Patract in the Polkadot Ecosystem
Parity: Building the Foundation of Web3
Parity Technologies is the original developer behind Polkadot and the Substrate framework. While initially focused on Ethereum tooling, Parity shifted its mission to enable a decentralized web—Web3—where users control their data and digital identities.
Helena emphasized that Parity’s core objective is to foster a robust, diverse, and sustainable ecosystem around Polkadot, Kusama, and Substrate. This involves:
- Supporting projects technically and strategically
- Organizing developer events like hackathons and workshops
- Creating pathways for high-potential teams to evolve into leading parachain candidates
"Developer activity, code contributions, and project quality are the real metrics that reflect a blockchain’s health—not just price or hype."
Parity’s approach in the Asia-Pacific region has been particularly aggressive, focusing on building a strong developer funnel: from awareness to deep technical engagement with Substrate.

Patract: Advancing Wasm Smart Contracts
While many ecosystems rely on Ethereum Virtual Machine (EVM)-compatible contracts, Patract is pioneering WebAssembly (Wasm) adoption in the Polkadot ecosystem. As a key contributor to Wasm-based smart contract infrastructure, Patract provides:
- Full-stack developer tools for Wasm contracts
- Runtime and contract module development for parachains
- Advocacy for standardized Wasm contract models across Polkadot
Santry Huang highlighted that Wasm offers superior performance, flexibility, and efficiency compared to EVM:
- Near-native execution speed (10–100x faster than EVM)
- Support for multiple programming languages (C++, Rust, Java)
- Lower gas costs due to optimized computation
Projects like Acala, Phala, and Bifrost are already adopting Wasm, signaling a shift toward high-performance smart contracts.
Why Wasm Is the Future of Smart Contracts
Technical Superiority Over EVM
Ethereum’s EVM was groundbreaking but comes with limitations:
- Limited instruction set
- High gas fees during congestion
- Language constraints (primarily Solidity)
In contrast, Wasm was co-developed by tech giants like Google, Microsoft, and Apple for web applications. Its design makes it ideal for blockchain:
- Portable bytecode executable across platforms
- Sandboxed security model
- High throughput and low latency
"Wasm allows complex DeFi logic to run efficiently—something EVM struggles with under load."
This is why not just Polkadot, but other next-gen blockchains like Solana and Dfinity are also adopting Wasm as their runtime engine.
The Patract Open Platform Initiative
To accelerate Wasm adoption, Patract launched the Patract Open Platform, a coalition of projects committed to advancing Wasm-based contracts on Polkadot. The alliance aims to:
- Standardize contract interfaces
- Improve developer tooling and documentation
- Propose upgrades to resource and economic models
With no native contract standard yet on Polkadot, community-driven efforts like this are crucial for long-term scalability.
Parachain Slot Auction: Current Progress
Step-by-Step Rollout Strategy
The parachain launch follows a cautious, phased approach:
- Testnet validation – Code tested on simulation networks
- Deployment on Kusama – Real-world testing in a live but experimental environment
- Empty shell deployment – Initial chains without full functionality
- Integration of auction and crowdloan modules
- Upgrade to Statemine – Kusama’s first live public parachain
- Launch of commercial parachain auctions
As of the latest update, Statemine has gone live, marking a major milestone. Any technical issues identified in early May have been resolved, and the team is preparing for the next phase.
Kusama as a Canary Network
Kusama serves as a "wild" version of Polkadot—faster governance, riskier upgrades—allowing teams to test parachain functionality before Polkadot deployment. The lessons learned here will directly inform Polkadot’s rollout strategy.
Risks and Opportunities in the Auction Process
Is Winning the “First Slot” Worth It?
There’s intense competition to win early parachain slots, but Helena cautions against chasing PR wins over strategic timing:
- Early slots come with unknown performance variables
- Market dynamics may favor later bidders as more slots become available
- Projects should assess their readiness rather than rush
Instead of aiming for first place, teams should focus on:
- Community strength (for crowdloans)
- Long-term sustainability
- Technical preparedness
Crowdloans: A Sustainable Funding Model
Projects without enough DOT can use crowdloans to raise support from token holders. In return, contributors receive project-specific rewards or future tokens. This model:
- Reduces financial pressure on startups
- Strengthens community engagement
- Aligns incentives between projects and users
Moreover, slots are auctioned in eight discrete time periods, allowing teams to bid only for the duration they need.
Parallel Threads: An Alternative Path
For projects that can’t afford full parachain status, parallel threads offer a scalable alternative. These operate under similar security guarantees but pay per-use fees instead of leasing an entire slot.
How Polkadot Compares to Ethereum
Layer 0 vs Layer 1 Architecture
While Ethereum operates as a Layer 1 blockchain, Polkadot functions as a Layer 0 protocol—a foundational network that connects multiple Layer 1 blockchains (parachains). This enables:
- Shared security via the relay chain
- Native cross-chain messaging (XCMP)
- Heterogeneous chain design (each parachain can have unique logic)
"You can build an Ethereum-like chain on Polkadot using Substrate—but you can’t build Polkadot on Ethereum."
This architectural advantage positions Polkadot as a potential successor platform for scalable dApp ecosystems.
Toward Web3 Interoperability
Polkadot’s vision goes beyond performance—it aims to create a truly interconnected blockchain internet, where data and assets flow freely across chains. Combined with bridges to external networks like Bitcoin or Ethereum, this could eliminate data silos and unlock new composability patterns.

Frequently Asked Questions
Q: Can you write Wasm smart contracts in C++?
A: Yes. Wasm supports multiple languages including C++, Rust, Java, and JavaScript, making it accessible to a broader range of developers.
Q: Are parachain slot auctions sustainable given the two-year lock-up period?
A: Yes. Slots are divided into eight lease periods, so teams can bid selectively. Crowdloans also distribute financial burden across the community.
Q: Is Polkadot’s auction similar to EOS’s DPoS model?
A: No. Polkadot uses a candle auction mechanism for fairness and decentralization. It doesn’t rely on elected block producers like EOS, preserving network neutrality.
Q: What happens if my project loses the auction?
A: You can retry in future auctions or opt for a parallel thread—a cost-effective alternative with similar functionality.
Q: How does Polkadot ensure security across parachains?
A: Through shared security via the relay chain. Validators are randomly assigned to parachains, reducing attack risks.
Q: When will Polkadot’s mainnet auctions begin?
A: After successful testing on Kusama, Polkadot’s auctions will follow using the same proven process.

Final Thoughts: A New Era for Blockchain Innovation
Polkadot’s journey is still in its early stages, but the foundation is solid. With Substrate enabling rapid chain development, Wasm unlocking high-performance smart contracts, and parachain auctions democratizing access to shared security, the ecosystem is poised for explosive growth.
The delay in rollout isn’t a setback—it’s a sign of responsible engineering. As Helena noted:
“Slow is fast. Stable progress beats rushed launches every time.”
For developers and investors alike, now is the time to engage deeply—not just financially, but technically and communally. The future of Web3 isn’t just about building better apps; it’s about building better foundations.
