Notes on adapting Miniscript for Tapscript

(Contains input from many people, not my own ideas)

Notes

  • Forbid multi, have a new multi_a itself forbidden in other contexts
  • We now need to care about the maximum stack size (1000). With Taproot it's now also checked before executing the Script.
  • We could have a new d: wrapper that is u because the MINIMALIF rule is consensus
  • It doesn't look like there is interesting combinations of the new CHECKSIGADD opcode with existing fragment. Maybe we could have used it for thresh to save an OP_ADD if the sub was a CHECKSIG, but the arguments aren't in the right order for this.
  • No need to check for the Script size anymore
  • I don't think we need to take the sigop budget into account, as we can't create a Script that would duplicate the signatures.
  • When calculating sizes, keep in mind the signature length is now 64

A quick script to plot the balance over time of a C-lightning routing node using the report from `bkpr-listincome`
import json
import matplotlib.pyplot as plt
import numpy as np
from datetime import datetime
STARTING_BALANCE = 0
with open("bkpr_report.json", "r") as report:
events = json.load(report)["income_events"]
