Specification

Interface specification is the following Contractum code:

-- Defined by LNPBP-31 standard in `RGBContract.sty` file
import urn:ubideco:stl:6vbr9ZrtsD9aBjo5qRQ36QEZPVucqvRRjKCPqE8yPeJr#choice-little-boxer as RGBContract

import RGB21

interface RGB23
    global id :: RGB21.ContractId
    global deed* :: Entry

    global created :: RGBContract.Timestamp

    owned deedRight

    op Log :: deedRight, deed -> deedRight

data Entry ::
    type MimeType,
    data [Byte],
    resources { ResourceId -> Resource }

data ResourceId :: U16

data Resource ::
    type MimeType,
    digest Digest

-- TODO: add more digest algorithms
-- TODO: move digest to Contractum standard library to use in RGB21
data Digest :: sha256([U8 ^ 32]) | blake3([U8 ^ 32])
