Breaking Monero Episode 05: Input Selection Algorithm
Channel: Monero Community Workgroup
Date: 2019-01-17

In this episode, Sarang and Justin explain more about how Monero selects decoys for ring signatures, more than just "randomly." We explain how Monero's selection algorithm has evolved over time, and how a strong input selection algorithm is critical for protective ring signatures.
