This can be a balanced tree if each of the conditions these scripts correspond to are equally likely.

These algorithms take advantage of helper functions from the [https://github.com/sipa/bips/blob/bip-schnorr/bip-schnorr/reference.py bip-schnorr reference code] for integer conversion, point multiplication, and tagged hashes. First, we define <code>taproot_tweak_pubkey</code> for 32-byte bip-schnorr public key arrays. In addition to the tweaked public key byte array, the function returns a boolean for the squareness of the tweaked points' Y coordinate modulo the secp256k1 field order. |
