Functions

func CFilterV2HeaderCommitment

func CFilterV2HeaderCommitment(net wire.CurrencyNet, header *wire.BlockHeader, filter *gcs.FilterV2, leafIndex uint32, proof []chainhash.Hash) error

CFilterV2HeaderCommitment ensures the given v2 committed filter has actually been committed to in the header, assuming dcp0005 was activated.

func DCP0005MerkleRoot

func DCP0005MerkleRoot(block *wire.MsgBlock) error

DCP0005MerkleRoot recreates the combined regular and stake transaction merkle root and compares it against the merkle root in the block header.

DCP0005 (https://github.com/decred/dcps/blob/master/dcp-0005/dcp-0005.mediawiki) describes (among other changes) the hard forking change which combined the individual regular and stake merkle roots into a single root.

func MerkleRoots

func MerkleRoots(block *wire.MsgBlock) error

MerkleRoots recreates the merkle roots of regular and stake transactions from a block and compares them against the recorded merkle roots in the block header.

func PreDCP0005CFilterHash

func PreDCP0005CFilterHash(net wire.CurrencyNet, cfsethash *chainhash.Hash) error

PreDCP0005CfilterHash returns nil if the hash for the given set of cf data matches the exepected hash for the given network.
