Slashing

Slashing penalizes storage providers that either fail to provide reliable uptime or act maliciously against the network. In Filecoin, storage providers are succeptible to two different kinds of slashing: storage fault slashing, and consensus fault slashing.

Storage fault slashing #

This term encompasses a broad set of penalties which are to be paid by storage providers if they fail to provide sector reliability or decide to voluntarily exit the network. These include:

• Fault fees are incurred for each day a storage provider’s sector is offline (fails to submit Proofs-of-Spacetime to the chain). Fault fees continue until the associated wallet is empty and the storage provider is removed from the network. In the case of a faulted sector, there will be an additional sector penalty added immediately following the fault fee.
• Sector penalties are incurred for a faulted sector that was not declared faulted before a WindowPoSt check occurs. The sector will pay a fault fee after a Sector Penalty once the fault is detected.
• Termination fees are incurred when a sector is voluntarily or involuntarily terminated and is removed from the network.

Consensus fault slashing #

This penalty is incurred when committing consensus faults. This penalty is applied to storage providers that have acted maliciously against the network’s consensus functionality.
