Network v16 Skyr (FVM M1) 🍼

🍼 Filecoin v16 Skyr upgrade will introduce Filecoin non-programmable WASM-based Filecoin Virtual Machine (FVM) to Filecoin mainnet. Upon the v16 Skyr upgrade, Mainnet will atomically switch from the current built-in VMs to the WASM-based reference FVM. A new gas model will be activated that accounts for actual WASM execution costs. Only built-in actors will be supported at this time. This upgrade will mark the completeness of FVM development Milestone 1.
