Orphan blocks. They’re the digital equivalent of a typo in a legal agreement—more aggravation than anything, typically harmless and easily mitigated. What do you do when those typos become routine, and the surrounding context indicates that they are likely intentional? That’s the second question swirling around Monero right now, and blowing it off as simple FUD might be a very expensive mistake.

Data Says Something's Off

Let's be clear: orphan blocks are normal. They occur in every decentralized blockchain where a large number of miners are trying to solve the same cryptographic hash puzzle. How regularly they occur is the crux of the matter. Spagni refutes that claim by arguing that the current rate is in the range of a normal distribution. This is true, indeed — on average — but statistics can be a treacherous thing.

Think of it like this: a city might have an "average" crime rate, but if you suddenly see a cluster of burglaries in a specific neighborhood over a short period, you don't just shrug and say, "Well, it's within the average!" You investigate.

From August 6th into 7th, we saw one nightmarish peak of five orphan blocks! Four of these blocks were credited to some “unknown” miner, which is extremely rare. Interested in seeing this history come to life through some cool visualizations? Just a simple bar chart showing the trend of orphan block rate over the past year would go very far. Is this just a blip, or the beginning of a new trend? It's time for some serious data analysis.

Selfish Mining A Real Threat?

This is where the “selfish mining” theory, proposed by ‘untraceable’, comes into play and things start to get interesting. Selfish mining is just one of the many tactics miners could choose to employ. They do this by artificially delaying a valid block they’ve found, hoping to build out or fork an even longer, secret chain. If they can outcompete the public chain on those grounds, they can always launch their own chain. This action will make all the other miners’ hard work futile.

Selfish mining is only profitable if you control a significant portion of the network's hashrate – usually over 33%. This is where CFB and Qubic come into play.

CFB, a principal developer of Qubic, has publicly expressed his desire to “take over” Monero’s hashrate. Now, I know what you're thinking: "PR stunt!" And maybe it is. But even if Qubic's hashrate is below that 33% threshold, the attempt to manipulate the network creates uncertainty and erodes trust.

Now picture a game of poker where one of the players constantly and very loudly pre-announces their intention to cheat. Even if they never end up cheating, that creates a huge problem in the game—the other players are going to be constantly on edge, wondering about every hand. That’s the counterproductive effect CFB is having, and it’s perilous.

Qubic's Silence Raises Red Flags

The very fact that Qubic has gone “silent,” concealing its hashrate, is chilling, too. Transparency is crucial in any decentralized system. Why the secrecy? What are they hiding? The fact that this raises the block discovery share of the “unknown” miners from 2% to 8% only adds to the suspicion.

It’s sort of akin to a black box on an airplane. When the whole thing blows up, of course everybody rushes in wanting to see the underlying data. Qubic’s unwillingness to publish its hashrate data would be akin to not releasing that black box following a collision.

Unintended Consequences Loom Large

What are the unintended negative effects to be feared in this scenario? Here's where my anxiety kicks in.

  • Centralization: If smaller mining pools become afraid of being orphaned, they might flock to larger, more established pools, leading to increased centralization of mining power. This defeats the very purpose of a decentralized cryptocurrency.
  • Erosion of Trust: The constant FUD and uncertainty can erode trust in Monero's security and privacy, potentially impacting its adoption and value.
  • Regulatory Scrutiny: Let's not forget the ever-watchful eyes of regulators. A perceived vulnerability in Monero's network could trigger increased regulatory scrutiny, potentially hindering its growth.

Mitigation Strategies A Must

This isn't just about some abstract technical issue. It's about the long-term health and viability of Monero. We must treat this with the utmost respect, study the data, and put in place appropriate mitigation measures while there’s still time to do so. It’s time for the industry to see all this dismissed as just FUD – fear, uncertainty and doubt. It's time to demand transparency and action. Now is an appropriate and urgent moment to reckon with the promise of complete secrecy. Are we prepared to accept the systemic risk this poses?

  • Mining Algorithm Review: Perhaps it's time to revisit Monero's mining algorithm to make it more resistant to selfish mining attacks.
  • Enhanced Network Monitoring: We need better tools to monitor the network in real-time and detect suspicious activity.
  • Community Education: The Monero community needs to be educated about the risks of selfish mining and how to identify and report suspicious behavior.
  • Incentivize Transparency: Monero should incentivize mining pools to be transparent about their hashrate.

This isn't just about some abstract technical issue; it's about the long-term health and viability of Monero. We need to take this seriously, analyze the data, and implement mitigation strategies before it's too late. Dismissing this as mere FUD is not only naive, but downright irresponsible. It's time to demand transparency and action. And maybe, just maybe, it's time to ask ourselves if the promise of absolute privacy is worth the potential for systemic risk.
