Multi-language Runtime Environments for Smart Contract Execution

on YouTube ↗30m

" summary

Implements a multi-language smart contract runtime inside a Scala blockchain client using GraalVM polyglot and Truffle, running JavaScript contracts on a Bifrost Akka node; demo executes increment and add functions, returns state updates and rejects wrong-typed arguments via a Truffle AST tooling pipeline that enforces parameter types. Uses sandbox instrumentation to keep guest code from affecting protocol state, targets off‑chain complexity estimation for fees, and runs on GraalVM 19.3 with the Prisomo simulator.
