§fn check_terminal_non_malleable<Pk>(
frag: &Terminal<Pk, Legacy>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
fn check_terminal_non_malleable<Pk>(
frag: &Terminal<Pk, Legacy>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
Depending on ScriptContext, fragments can be malleable. For Example,
under Legacy context, PkH is malleable because it is possible to
estimate the cost of satisfaction because of compressed keys
This is currently only used in compiler code for removing malleable
compilations.
This does NOT recursively check if the children of the fragment are
valid or not. Since the compilation proceeds in a leaf to root fashion,
a recursive check is unnecessary.
§fn check_pk<Pk>(pk: &Pk) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
fn check_pk<Pk>(pk: &Pk) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
Each context has slightly different rules on what Pks are allowed in descriptors
Legacy/Bare does not allow x_only keys
Segwit does not allow uncompressed keys and x_only keys
Tapscript does not allow uncompressed keys
§fn check_witness(witness: &[Vec<u8>]) -> Result<(), ScriptContextError>
fn check_witness(witness: &[Vec<u8>]) -> Result<(), ScriptContextError>
Check whether the given satisfaction is valid under the ScriptContext
For example, segwit satisfactions may fail if the witness len is more
3600 or number of stack elements are more than 100.
§fn check_global_consensus_validity<Pk>(
ms: &Miniscript<Pk, Legacy>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
fn check_global_consensus_validity<Pk>(
ms: &Miniscript<Pk, Legacy>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
Depending on script Context, some of the Terminals might not
be valid under the current consensus rules.
Or some of the script resource limits may have been exceeded.
These miniscripts would never be accepted by the Bitcoin network and hence
it is safe to discard them
For example, in Segwit Context with MiniscriptKey as bitcoin::PublicKey
uncompressed public keys are non-standard and thus invalid.
In LegacyP2SH context, scripts above 520 bytes are invalid.
Post Tapscript upgrade, this would have to consider other nodes.
This does NOT recursively check the miniscript fragments.
§fn check_local_consensus_validity<Pk>(
ms: &Miniscript<Pk, Legacy>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
fn check_local_consensus_validity<Pk>(
ms: &Miniscript<Pk, Legacy>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
Consensus rules at the Miniscript satisfaction time.
It is possible that some paths of miniscript may exceed resource limits
and our current satisfier and lifting analysis would not work correctly.
For example, satisfaction path(Legacy/Segwitv0) may require more than 201 opcodes.
§fn check_local_policy_validity<Pk>(
ms: &Miniscript<Pk, Legacy>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
fn check_local_policy_validity<Pk>(
ms: &Miniscript<Pk, Legacy>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
Policy rules at the Miniscript satisfaction time.
It is possible that some paths of miniscript may exceed resource limits
and our current satisfier and lifting analysis would not work correctly.
For example, satisfaction path in Legacy context scriptSig more
than 1650 bytes
§fn max_satisfaction_size<Pk>(ms: &Miniscript<Pk, Legacy>) -> Option<usize>where
Pk: MiniscriptKey,
fn max_satisfaction_size<Pk>(ms: &Miniscript<Pk, Legacy>) -> Option<usize>where
Pk: MiniscriptKey,
Depending on script context, the size of a satifaction witness may slightly differ.
§fn pk_len<Pk>(pk: &Pk) -> usizewhere
Pk: MiniscriptKey,
fn pk_len<Pk>(pk: &Pk) -> usizewhere
Pk: MiniscriptKey,
Get the len of public key when serialized based on context
Note that this includes the serialization prefix. Returns
34/66 for Bare/Legacy based on key compressedness
34 for Segwitv0, 33 for Tap
§fn check_global_policy_validity<Pk>(
_ms: &Miniscript<Pk, Self>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
fn check_global_policy_validity<Pk>(
_ms: &Miniscript<Pk, Self>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
Depending on script Context, some of the script resource limits
may have been exceeded under the current bitcoin core policy rules
These miniscripts would never be accepted by the Bitcoin network and hence
it is safe to discard them. (unless explicitly disabled by non-standard flag)
For example, in Segwit Context with MiniscriptKey as bitcoin::PublicKey
scripts over 3600 bytes are invalid.
Post Tapscript upgrade, this would have to consider other nodes.
This does NOT recursively check the miniscript fragments.
§fn check_global_validity<Pk>(
ms: &Miniscript<Pk, Self>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
fn check_global_validity<Pk>(
ms: &Miniscript<Pk, Self>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
Check the consensus + policy(if not disabled) rules that are not based
satisfaction
§fn check_local_validity<Pk>(
ms: &Miniscript<Pk, Self>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
fn check_local_validity<Pk>(
ms: &Miniscript<Pk, Self>
) -> Result<(), ScriptContextError>where
Pk: MiniscriptKey,
Check the consensus + policy(if not disabled) rules including the
ones for satisfaction
§fn top_level_type_check<Pk>(ms: &Miniscript<Pk, Self>) -> Result<(), Error>where
Pk: MiniscriptKey,
fn top_level_type_check<Pk>(ms: &Miniscript<Pk, Self>) -> Result<(), Error>where
Pk: MiniscriptKey,
Check whether the top-level is type B
§fn other_top_level_checks<Pk>(_ms: &Miniscript<Pk, Self>) -> Result<(), Error>where
Pk: MiniscriptKey,
fn other_top_level_checks<Pk>(_ms: &Miniscript<Pk, Self>) -> Result<(), Error>where
Pk: MiniscriptKey,
Other top level checks that are context specific
§fn top_level_checks<Pk>(ms: &Miniscript<Pk, Self>) -> Result<(), Error>where
Pk: MiniscriptKey,
fn top_level_checks<Pk>(ms: &Miniscript<Pk, Self>) -> Result<(), Error>where
Pk: MiniscriptKey,
Check top level consensus rules.
