Dear Polkadot Governance Forum Members,

I’m thrilled to share with you a groundbreaking project that emerged from our recent experiences at the PBA Campus in Lucerne - Bend-PVM, a next-generation smart contract language specifically designed for the PolkaVM ecosystem.

The Genesis of Bend-PVM

The inspiration for Bend-PVM struck during Module 3 of our PBA training, where P.G. Herveou, Erin Grasmick, and Cyrill Leutwiler from Parity illuminated the intricate architecture of Polkadot, PolkaVM, and smart contracts. It became clear that while Polkadot offers revolutionary technical advantages, we need specialized tools to fully harness its potential.

Why Bend-PVM Matters for Polkadot

Polkadot’s ecosystem growth fundamentally depends on developer adoption. Currently, millions of developers are comfortable with Ethereum’s development environment, creating a significant barrier to entry for Polkadot. Bend-PVM bridges this gap by offering:

  • Familiar Syntax with Enhanced Power: 90% Solidity compatibility paired with functional programming paradigms from the Bend language
  • RISC-V Optimization: Leveraging PolkaVM’s efficient instruction set for superior performance
  • Multi-Dimensional Resource Model: A revolutionary approach to resource management that transcends Ethereum’s one-dimensional gas model

Technical Innovation

Bend-PVM introduces several technical innovations that align perfectly with Polkadot’s architecture:

  1. Three-Dimensional Resource Metering:

    • ref_time: Computational resources (similar to Ethereum gas)
    • proof_size: State proof size for Polkadot validators
    • storage_deposit: Prevention of state bloat with deposit/refund mechanism

  2. Functional Programming Features:

    • Pattern matching for elegant data handling
    • Algebraic data types for type-safe representation
    • Monadic error handling with Result type

  3. Ethereum Compatibility Layer:

    • Seamless migration path for existing Solidity contracts
    • Familiar development workflow for Ethereum developers

Ecosystem Impact

The introduction of Bend-PVM has far-reaching implications for Polkadot’s ecosystem:

  • Developer Influx: Lowering the barrier to entry for Ethereum developers
  • Application Diversity: Enabling more complex DeFi, NFT, gaming, and governance applications
  • Resource Efficiency: Reducing transaction costs while increasing computational capabilities
  • Security Enhancements: Leveraging functional programming paradigms for safer smart contracts

Current Status and Roadmap

We’ve launched an initial website at https://bend-pvm.aipop.fun/ and established our repository at https://github.com/developerfred/Bend-PVM.

Our roadmap includes:

  • Q2 2025: Alpha release with core language features
  • Q3 2025: Beta release with full standard library
  • Q4 2025: Production release with comprehensive tooling
  • Q1 2026: Ecosystem expansion and community adoption

The Role of PBA in Bend-PVM’s Development

I cannot overstate the impact of the Polkadot Blockchain Academy on this project’s conception. The deep technical insights provided during the Lucerne campus modules, particularly the session on Polkadot architecture and PolkaVM, were instrumental in identifying this opportunity and shaping the technical direction of Bend-PVM.

Call for Collaboration

For Bend-PVM to reach its full potential, we need the collective expertise and support of the Polkadot community:

  1. Technical Feedback: Insights on our resource model and RISC-V implementation
  2. Early Adopters: Projects willing to experiment with Bend-PVM in development
  3. Integration Support: Guidance on optimal integration with Polkadot’s infrastructure
  4. Access to PolkaVM Beta: Early access would accelerate our development timeline

Conclusion

The strength of any blockchain ecosystem ultimately depends on its developer tools. With Bend-PVM, we have an opportunity to dramatically expand Polkadot’s developer base by offering a familiar yet powerful way to harness PolkaVM’s capabilities.

I firmly believe that with the right tools, Polkadot can attract a massive influx of developers from Ethereum and other ecosystems. Bend-PVM aims to be that critical bridge, combining the best of Ethereum’s accessibility with Polkadot’s technical superiority.

I welcome your thoughts, questions, and especially your critical feedback on how we can refine this vision to best serve the Polkadot ecosystem.

Committed to Polkadot success,
