In this short episode, we discuss the unfortunate tradeoff when sending Monero transactions with unusual ringsizes. Some transactions were sent with ringsizes over 1000. Monero moved to consensus-mandated ringsizes in a recent update instead of minimum ringsizes. Thus, the concerns in this video serve an informative purpose, but they do not have any current relevance.

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.

In this episode, Sarang, Brandon (Suare), and Justin introduce key image reuse concerns. We explain some techniques to protect security and privacy under a number of circumstances. Ultimately, users should not claim "airdrop" funds if they have not thought long and hard about the implications.

Sarang and Justin discuss 0-decoy (0-mixin) rings, perhaps the oldest and best-studied past limitation of Monero. We discuss how research created for 0-decoy rings can be applied to other analysis types. We show a spreadsheet tool we use to test chain reaction impacts, which can be caused by a large number of possible Monero attacks. By understanding the basics of 0-decoy research, individuals can more easily understand how we study the potential impacts of other attacks and analysis.

Welcome to the first episode of Breaking Monero! Breaking Monero is a series of episodes where we explain the limitations of Monero’s security and privacy in a comprehensive and understandable way. We give a sneak peek into some of the work done behind the scenes to evaluate risks and to make Monero better. It’s an ongoing process, and we are happy to have you here along with us for this part of Monero’s journey!

What does the OFAC blacklisting of Bitcoin addresses mean for btc and has this news changed @Jwweatherman_'s opinion of Monero, or is it still a worthless scam coin.
