Functions ¶
func CommP ¶
func CommP(ctx context.Context, bs bstore.Blockstore, data *storagemarket.DataRef, maxTraversalLinks uint64) (cid.Cid, abi.UnpaddedPieceSize, error)
CommP calculates the commP for a given dataref In Markets, CommP = PieceCid. We can't rely on the CARv1 payload in the given CARv2 file being deterministic as the client could have written a "non-deterministic/unordered" CARv2 file. So, we need to do a CARv1 traversal here by giving the traverser a random access CARv2 blockstore that wraps the given CARv2 file.
func LabelField ¶
LabelField makes a label field for a deal proposal as a multibase encoding of the payload CID (B58BTC for V0, B64 for V1)
func VerifyResponse ¶
func VerifyResponse(ctx context.Context, resp network.SignedResponse, minerAddr address.Address, tok shared.TipSetToken, verifier VerifyFunc) error
VerifyResponse verifies the signature on the given signed response matches the given miner address, using the given signature verification function
