Abstract

We present a garbage collector that is specifically designed for a WebAssembly-based blockchain. Applications on the blockchain implement smart contracts that may have indefinitely long lifetime and may hold substantial monetary value. This imposes a different set of requirements for garbage collection compared to traditional platforms. In this paper, we explain the differences and show our garbage collector optimizes towards these goals.
