Variants§
Fetch
Fetches the most recent snapshot from a trusted, pre-defined location.
Fields
chain: NetworkChain
Network chain the snapshot will belong to
vendor: TrustedVendor
Vendor to fetch the snapshot from
ValidateDiffs
Validate the provided snapshots as a whole.
Fields
check_network: Option<NetworkChain>
Assert the snapshot belongs to this network. If left blank, the network will be inferred before executing messages.
Validate
Validate the snapshots individually.
Fields
check_network: Option<NetworkChain>
Assert the snapshot belongs to this network. If left blank, the network will be inferred before executing messages.
Compress
Make this snapshot suitable for use as a compressed car-backed blockstore.
Fields
ComputeState
Filecoin keeps track of “the state of the world”, including: wallets and their balances; storage providers and their deals; etc…
It does this by (essentially) hashing the state of the world.
The world can change when new blocks are mined and transmitted. A block may contain a message to e.g transfer FIL between two parties. Blocks are ordered by “epoch”, which can be thought of as a timestamp.
Snapshots contain (among other things) these messages.
The command calculates the state of the world at EPOCH-1, applies all the messages at EPOCH, and prints the resulting hash of the state of the world.
If –json is supplied, details about each message execution will printed.
