Hello everyone, I made a pull request for adding ec_sum to math/ https://github.com/libbitcoin/libbitcoin/pull/922

GitHub

added new function to math/ called ec_sum. Adds a list of provided ec points together. by narodnik · Pull Request #922 · libbitcoin/libbitcoin

Provided unit test. Neccessary for modern privacy schemes which hide sharing amounts. They involve summing points from different curves together: A + B + C. This function provides that functionality.

This is great! I was trying to do petersen commitment (C = rH + aG) with ec math a couple weeks ago in Libbitcoin, and this was exactly what I needed! Previously could only add multiples of Generator points.
