The Polkadot ecosystem is poised for a developer-focused upgrade as Dedot announces support for pallet-revive and ink! v6 through its Ink!ubator 2.0 program. This technical proposal by community member [sinzii] aims to enhance smart contract capabilities by bridging Polkadot’s core infrastructure with Phala Network’s off-chain computing power.
The integration enables ACID-compliant transactions (Atomicity, Consistency, Isolation, Durability) for decentralized applications through a novel request-response model. Developers can now combine on-chain smart contracts with verifiable off-chain computations executed on RISC-V processors, as detailed in the original forum proposal.
This upgrade addresses long-standing challenges in creating atomic multi-step transactions on Polkadot. The solution leverages Phala Cloud’s decentralized cloud infrastructure for reliable state management while maintaining blockchain security guarantees.

Polkadot’s Ecosystem Evolution
The implementation marks a strategic shift from WebAssembly to RISC-V architecture for smart contract execution. pallet-revive serves as the new execution environment for Kusama and Polkadot AssetHub chains, replacing the older pallet-contracts system.
Key improvements include:
- Transactional KV-store for stateful dApps
- Native support for mixed on-chain/off-chain workflows
- Enhanced developer tools through JavaScript/TypeScript SDKs
This architectural change enables developers to build complex applications requiring coordinated actions across multiple subsystems – a capability previously hampered by Polkadot’s isolated runtime environments.
Understanding pallet-revive
The revamped smart contract module introduces three core innovations:
| Feature | Impact |
|---|---|
| ACID Compliance | Ensures database transactions complete fully or roll back completely |
| Phala Cloud Integration | Provides decentralized cloud infrastructure for off-chain computations |
| RISC-V Runtime | Enables multi-language support beyond Rust-based ink! contracts |
Notably, pallet-revive’s design allows future support for additional programming languages through RISC-V compilation targets. The system currently supports ink! and Solidity via Parity’s revive compiler.
The Role of ink! v6
ink! v6 represents a major overhaul of Polkadot’s primary smart contract language. Developers must now:
- Use unreleased master branch builds
- Transition from WebAssembly to RISC-V targets
- Implement new storage access patterns
The update introduces a two-part SDK architecture – Rust libraries for on-chain contracts and JavaScript tools for Phala Cloud integration. This separation allows frontend applications to directly interact with smart contracts through WebSocket/HTTP connections.
Early adopters report 40-60% gas cost reductions in prototype applications, though comprehensive benchmarks remain pending. The upgrade particularly benefits DeFi protocols requiring complex state transitions across multiple contracts.
