How might Taproot be implemented in BCH, and do we need it?

Taproot is an interesting technology to enable multiparty privacy on a bitcoin. Currently, there is a problem with multiparty contracts in that they are obvious deviation from the most common script type (P2PKH), which hurts privacy. The script that gets used will typically indicate exactly what kind of protocol was at play. Also complex P2SH scripts take extra resources (transaction size and CPU cycles).

The basic idea with Taproot is that instead of P2SH where a script is committed by a hash, you can hide a script (or set of possible scripts) as a commitment within a normal-looking public key. Now there are two ways to spend from this public key:

  1. Create a normal transaction signature using the public key, or,
  2. Reveal the commitment, and provide parameters that satisfy the revealed script.

To do #1, it means you need to know the private key, or, you have a set of signers who are able to produce a signature (that's where Schnor

PMv3 BCH Network Discussion Notes (June 1, 2021)

1. Problem Statement/Use Case

Without going into any history or context, what are the practical implications of solving the problem you’re trying to solve?

Bitcoin Cash already has a very powerful programming language – by solving an issue with how transactions are formatted, we'll be able to build advanced, Decentralized Finance (DeFi) applications which scale better than those on "global state" networks like Ethereum.

What use-cases would be enabled, and why should they be accommodated?

PMv3 would allow BCH developers to build almost any kind of decentralized application currently possible on other "smart contract"-focused cryptocurrency networks, including prediction markets, synthetic assets, and decentralized exchanges.
