Networks
There are three networks available for Filecoin:
- Mainnet, the only production Filecoin network.
- Calibration, the primary testing network for Filecoin.
- Devnet, the local development network designed to run with minimal resources for development testing.
Mainnet
Mainnet is the primary Filecoin network. Mainnet began on block 148,888. It supports 32 GiB and 64 GiB sectors.

Calibration
Calibration network is the most realistic simulation of the Filecoin mainnet:
- Prospective storage providers can experience realistic sealing performance and hardware requirements due to the use of final proofs constructions and parameters.
- Prospective storage clients can store and retrieve real data on the network. Clients can participate in deal-making workflows and storage + retrieval functionality.
- Same sector size as mainnet. The calibration network supports 32 GiB and 64 GiB sectors.
