Filecoin / PL Launchpad

This talk given by zenground0 in July of 2022 takes a deep dive into the actors that make up the computational model of the Filecoin protocol. Learn about why Filecoin uses actors, the different types of actors, and what the current eleven available Filecoin actors do. Understand the upgrades that have occurred since mainnet launch. As the Filecoin Virtual Machine (FVM) is developed, the capabilities of Filecoin actors will greatly expand along with the potential for the Filecoin Protocol, by decoupling adding functionality from protocol upgrades and allowing for independent user actors.
