Design principles:
- human-readable; small visual clutter (python-like, thus "stinger")
- supporint client-side-validation
- deterministic and fully transcodable with bitcoin script (
decode(encode(jet)) = jet; encode(decode(bitcoin_script)) = bitcoin_script; this means LN support) - supporting any existing scriptPubkey descriptors
- compact: frequently used complex expressions can be convolved into a short terms ("jets")
- evolving: new jets may be added with time (for new bitcoin features etc)
Example:

# This means derivation standard used. Here we use m/33/chain/org/unit/account/scope/index
use lnpbp derivation
# This defines organization units in derivation (see "unit" in the path above).
let board = unit 1
# This defines account index used by all participants under the same org unit
# (see "account" in the path above).
let current = account 2
# These are participant-specific components of derivation paths:
# - seed fingerprint
# - organization index (different participants may use different indexes for the same org)
# - organization unit
# - account index - taken from the definition above
let maxim = seed bf8564fd org 2 board current xpub.... with descriptor-wallet at paris-server
let giacomo = seed 88eca544 org 5 board current xpub.... with electrum at desktop-home
let olga = seed 9245a67c org 0 board current xpub.... with bitbox02 at home
let lawyer = seed 7835dc3d org 122 board current xpub.... with trezor at bank-safe-box
# These defines a group of users participating in multisig
let boardMembers = group maxim, giacomo, olga
descriptors: tr, wsh, shWsh
# Conditions which must be satisfied for UTXO spending:
# they are organized as a list, transformed into a tree for taproot
# outputs or linearized with OR operators for other types of outputs.
# For taproot the order of conditions must follow the probability
# of their usage (DFS ordering).
satisfying any:
all of boardMembers signed in the order of their pubkeys
tapret # here we allow wallets to put tapret commitments
at least 2 of boardMembers signed after 2 years in the order of their pubkeys
at least 1 of boardMembers signed after 3 years in the order of their pubkeys
lawyer signed after 5 years
