; This is a hash of data which may affect evaluation of a script.
; This data consists of:
;   - The redeemers from the transaction_witness_set (the value of field 5).
;   - The datums from the transaction_witness_set (the value of field 4).
;   - The value in the costmdls map corresponding to the script's language
;     (in field 18 of protocol_param_update.)
; (In the future it may contain additional protocol parameters.)
; 
; Since this data does not exist in contiguous form inside a transaction, it needs
; to be independently constructed by each recipient.
; 
; The bytestring which is hashed is the concatenation of three things:
;   redeemers || datums || language views
; The redeemers are exactly the data present in the transaction witness set.
; Similarly for the datums, if present. If no datums are provided, the middle
; field is omitted (i.e. it is the empty/null bytestring).
; 
; language views CDDL:
; { * language => script_integrity_data }
; 
; This must be encoded canonically, using the same scheme as in
; RFC7049 section 3.9:
;  - Maps, strings, and bytestrings must use a definite-length encoding
;  - Integers must be as small as possible.
;  - The expressions for map length, string length, and bytestring length
;    must be as short as possible.
;  - The keys in the map must be sorted as follows:
;     -  If two keys have different lengths, the shorter one sorts earlier.
;     -  If two keys have the same length, the one with the lower value
;        in (byte-wise) lexical order sorts earlier.
; 
; For PlutusV1 (language id 0), the language view is the following:
;   - the value of costmdls map at key 0 (in other words, the script_integrity_data)
;     is encoded as an indefinite length list and the result is encoded as a bytestring.
;     (our apologies)
;     For example, the script_integrity_data corresponding to the all zero costmodel for V1
;     would be encoded as (in hex):
;     58a89f00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000ff
;   - the language ID tag is also encoded twice. first as a uint then as
;     a bytestring. (our apologies)
;     Concretely, this means that the language version for V1 is encoded as
;     4100 in hex.
; For PlutusV2 (language id 1), the language view is the following:
;   - the value of costmdls map at key 1 is encoded as an definite length list.
;     For example, the script_integrity_data corresponding to the all zero costmodel for V2
;     would be encoded as (in hex):
;     98af0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
;   - the language ID tag is encoded as expected.
;     Concretely, this means that the language version for V2 is encoded as
;     01 in hex.
; 
; Note that each Plutus language represented inside a transaction must have
; a cost model in the costmdls protocol parameter in order to execute,
; regardless of what the script integrity data is.
; 
; Finally, note that in the case that a transaction includes datums but does not
; include the redeemers field, the script data format becomes (in hex):
; [ 80 | datums | A0 ]
; corresponding to a CBOR empty list and an empty map.
; Note that a transaction might include the redeemers field and set it to the
; empty map, in which case the user supplied encoding of the empty map is used.

; The real unit_interval is: #6.30([uint, uint])
; 
; A unit interval is a number in the range between 0 and 1, which
; means there are two extra constraints:
;   1. numerator <= denominator
;   2. denominator > 0
; 
; The relation between numerator and denominator can be
; expressed in CDDL, but we have a limitation currently
; (see: https://github.com/input-output-hk/cuddle/issues/30)
; which poses a problem for testing. We need to be able to
; generate random valid data for testing implementation of
; our encoders/decoders. Which means we cannot use the actual
; definition here and we hard code the value to 1/2
