Expand description

Trait describing a lookup table for signatures, hash preimages, etc. Every method has a default implementation that simply returns None on every query. Users are expected to override the methods that they have data for.

Provided Methods

Given a public key, look up an ECDSA signature with that key

Lookup the tap key spend sig

Given a public key and a associated leaf hash, look up an schnorr signature with that key

Obtain a reference to the control block for a ver and script

Given a Pkh, lookup corresponding Pk

Given a keyhash, look up the EC signature and the associated key Even if signatures for public key Hashes are not available, the users can use this map to provide pkh -> pk mapping which can be useful for dissatisfying pkh.

Given a keyhash, look up the schnorr signature and the associated key Even if signatures for public key Hashes are not available, the users can use this map to provide pkh -> pk mapping which can be useful for dissatisfying pkh.

Given a SHA256 hash, look up its preimage

Given a HASH256 hash, look up its preimage

Given a RIPEMD160 hash, look up its preimage

Given a HASH160 hash, look up its preimage

Assert whether an relative locktime is satisfied

Assert whether a absolute locktime is satisfied

Assert if tx template is satisfied
