Scripts
type SerializedScript = ShortByteString Source #
Scripts to the ledger are serialised bytestrings.
A script on the chain. This is an opaque type as far as the chain is concerned.
Instances
| Eq Script Source # |
Note [Using Flat inside CBOR instance of Script] `plutus-ledger` uses CBOR for data serialisation and `plutus-core` uses Flat. The choice to use Flat was made to have a more efficient (most wins are in uncompressed size) data serialisation format and use less space on-chain. To make `plutus-ledger` work with scripts serialised with Flat, and keep the CBOR format otherwise we have defined a Serialise instance for Script, which is a wrapper over Programs serialised with Flat. The instance will see programs as an opaque ByteString, which is the result of encoding programs using Flat. Because Flat is not self-describing and it gets used in the encoding of Programs, data structures that include scripts (for example, transactions) no-longer benefit for CBOR's ability to self-describe it's format. |

fromCompiledCode :: CompiledCode a -> Script Source #
Turn a

) into a
Script
for use with this package.
Validating scripts
isScriptWellFormed :: ProtocolVersion -> SerializedScript -> Bool Source #
Check if a
Script
is "valid" according to a protocol version. At the moment this means "deserialises correctly", which in particular
implies that it is (almost certainly) an encoded script and the script does not mention any builtins unavailable in the given protocol version.
Running scripts
evaluateScriptRestricting Source #
Arguments
| :: ProtocolVersion | |
| -> VerboseMode |
Whether to produce log output |
| -> EvaluationContext |
The cost model that should already be synced to the most recent cost-model-params coming from the current protocol |
| -> ExBudget |
The resource budget which must not be exceeded during evaluation |
| -> SerializedScript |
The script to evaluate |
| -> [ Data ] |
The arguments to the script |
| -> ( LogOutput , Either EvaluationError ExBudget ) |
Evaluates a script, with a cost model and a budget that restricts how many resources it can use according to the cost model. Also returns the budget that was actually used.
Can be used to calculate budgets for scripts, but even in this case you must give a limit to guard against scripts that run for a long time or loop.
evaluateScriptCounting Source #
Arguments
| :: ProtocolVersion | |
| -> VerboseMode |
Whether to produce log output |
| -> EvaluationContext |
The cost model that should already be synced to the most recent cost-model-params coming from the current protocol |
| -> SerializedScript |
The script to evaluate |
| -> [ Data ] |
The arguments to the script |
| -> ( LogOutput , Either EvaluationError ExBudget ) |
Evaluates a script, returning the minimum budget that the script would need
to evaluate successfully. This will take as long as the script takes, if you need to
limit the execution time of the script also, you can use
evaluateScriptRestricting
, which
also returns the used budget.

Cost model
data EvaluationContext Source #
An opaque type that contains all the static parameters that the evaluator needs to evaluate a script. This is so that they can be computed once and cached, rather than recomputed on every evaluation.
There are two sets of parameters: one is with immediate unlifting and the other one is with deferred unlifting. We have to keep both of them, because depending on the language version either one has to be used or the other. We also compile them separately due to all the inlining and optimization that need to happen for things to be efficient.

Value
A cryptocurrency value. This is a map from
CurrencySymbol
s to a
quantity of that currency.
Operations on currencies are usually implemented
pointwise
. That is,
we apply the operation to the quantities for each currency in turn. So
when we add two
Value
s the resulting
Value
has, for each currency,
the sum of the quantities of
that particular
currency in the argument
Value
. The effect of this is that the currencies in the
Value
are "independent",
and are operated on separately.
Whenever we need to get the quantity of a currency in a
Value
where there
is no explicit quantity of that currency in the
Value
, then the quantity is
taken to be zero.
See note [Currencies] for more details.

data BuiltinData Source #
A type corresponding to the Plutus Core builtin equivalent of
Data
.
The point of this type is to be an opaque equivalent of
Data
, so as to
ensure that it is only used in ways that the compiler can handle.
As such, you should use this type in your on-chain code, and in any data structures that you want to be representable on-chain.
For off-chain usage, there are conversion functions
builtinDataToData
and
dataToBuiltinData
, but note that these will not work on-chain.
