Inference, a formal verification framework, analyzes three WebAssembly-based blockchains for verifiability. Stellar Soroban emerges as the most feasible target due to its minimalist architecture and strict separation of business logic from infrastructure, unlike Polkadot's monolithic design.
Inference, an innovative formal verification framework, compares three major blockchain platforms targeting WebAssembly: Polkadot Substrate, Stellar Soroban, and Arbitrum Stylus. The analysis reveals that architectural choices fundamentally impact verifiability. Polkadot's modular pallet system collapses into a monolithic binary during compilation, making formal verification nearly impossible. Stellar Soroban's minimalist C/C++ core and strict WebAssembly sandbox isolation create ideal conditions for verification, with business logic completely separated from infrastructure. Arbitrum Stylus occupies a middle ground, using Go and EVM persistence which adds complexity. The framework consists of an Inference compiler, mechanized WebAssembly semantics in Rocq theorem prover, and a mathematical theory enabling contract verification with unprecedented ease.
