Resource hardening

[lemmih]

Summary

Executing Filecoin transactions are computationally expensive, caches are vital for performance but eat up memory, we rely on the p2p swarm but any individual peer may be unreliable. As of writing, Forest does not have any clear bounds on computation, memory, or network usage.

Motivation

Forest operators would benefit from clear requirements. Additionally, having bounded requirements is essential for security and resisting attacks.

Tasks

• Enumerate all caches, justify their size, and minimize if possible.
• Decouple the swarm from the execution layer.
• Make sure only validated data is comitted to the database.
