The calibration network is the most realistic testnet simulation of the Filecoin mainnet.

Calibration network is the most realistic simulation of the Filecoin mainnet.

  • Prospective storage providers can experience more 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.
