Unspendable Pubkey Generator

Generates a verifiably unspendable pubkey for the secp256k1 elliptic curve using the strategy outlined in bip0341.

An unspendable pubkey is a point on the curve whose discrete log is not known with respect to the generator point G. This can be verified by revealing the random scalar r used to generate the pubkey by shifting the NUMS point.

Prerequisites

1. Install sage as per these instructions.

2. (Optional) Install poetry as per these instructions.

Run

If poetry is installed
