A “significant” decoy selection bug has been reported for Monero via the project’s official Twitter handle. According to the investigation, carried out by software developer Justin Berman, the bug “may impact your transaction’s privacy” during a brief window of time after funds have been received.

If users spend funds immediately following the lock time in the first 2 blocks allowable by consensus rules (~20 minutes after receiving funds), then there is a good probability that the output can be identified as the true spend.

Monero Research Lab clarified that the data at risk of exposure is related to addresses or transactions amounts, the funds themself are “Never at risk of being stolen”. Since the report was published around 10 hours ago, the bug has persisted in the “official wallet code”.

In order to mitigate the bug, users can wait 1 hour before spending funds after receiving them. Developers are currently working on a wallet software update. This won’t need to be implemented via a Hard Fork.

The Monero Research Lab and Monero developers take this matter very seriously. We will provide an update when wallet fixes are available.

A Potential Fix For The Monero Decoy Selection Bug

On the Monero Project GitHub repository, Berman made a detailed explanation of the bug. He revealed that his investigation was run by core developers before it was published. He clarified that the decoy selection mechanism that affects the software wallet has “0 change of selecting extremely recent outputs as decoys”.

Thus, why users can mitigate the bug by spending their funds after a while. As the developer clarified, the algorithm introduces 10 “decoys” into a Monero ring, later, it hides the real output. The selection mechanism has almost 0 chance of selecting a decoy with less than 100 outputs, but still, the probability is there:

The fact that there is still a chance to select a decoy with output index <100 is thanks to this part of the algorithm which takes the output_index determined by exp(x), finds the block it’s in, and then randomly selects an output from that block. So outputs from blocks that have >100 outputs have a chance at being selected as decoys.

Although it is still under development, Berman believes that the solution for the Monero bug will require a modification to the decoy selection mechanism. This could potentially impact the uniformity of the transactions if they are processed by a node without the update versus the way update nodes will construct rings, the developer said.

The fix I’m leaning toward at the moment is that the algorithm is off by 1 block, meaning that the paper’s observed gamma distribution simply plotted observed spents. At a block time of 120 seconds, you would expect next to 0 outputs to be spent in less than 120 seconds, which the paper’s recommended gamma distribution seems to corroborate.

At the time of writing, Monero (XMR) trades at $220.95 with a 16.1% profit in the weekly chart. XMR follows the general market sentiment moving sideways after a significant push to the upside during the weekend.

Reynaldo Marquez

A literature major, Reynaldo Márquez has been deeply immersed in the crypto industry since 2017. His journey began with translating articles for various crypto news outlets, a role he took on with zeal. In 2018, amidst a challenging market, he embraced his first writing assignment, demonstrating his unwavering commitment to the nascent industry and the promise of change it bears for many people worldwide.
In March 2021, he joined the prestigious crypto news outlet NewsBTC and Bitcoinist, where he not only reported on the latest crypto news but also had the privilege of interviewing some of the industry's most influential figures. A year later, his dedication and hard work were recognized, and he was promoted to Managing Editor, a position he currently holds with pride.
He believes in honesty, good communication, hard work, and the power of cryptocurrency and its potential to transform people's lives, especially those alienated by the legacy financial system. Born in 1992 in Venezuela, Reynaldo is familiar with how governments and central banks can negatively affect people, their everyday lives, and their futures by creating inflation and erasing their hopes for a better future. Thus, like many Venezuelans, he embraced this new technology to help him and his family navigate difficult times.
In another life, Reynaldo would have pursued a career as an investigator, most likely tracking down the origins of the Cyberpunk movement with the publication of William Gibson’s ‘Neuromancer.’ The intersection between fiction and reality, with the materialization of Bitcoin in 2009, would have allowed him to dive deep into the crypto sphere as something more than a financial phenomenon but also a cultural shift in society that was brewing since the XX century, and maybe even sooner, in the XIX century with the publication of Henry David Thoreau’s ‘Civil Disobedience.’
But that’s for another life. In this one, Reynaldo has been trading to improve his trading skills. Since 2023, he has been trying to learn Python to create successful strategies and find ways to execute them. It is a difficult task, which continues to keep him busy today and will most likely continue to keep him busy in the near and long term.
In his free time, he enjoys lifting heavy objects, reading, watching movies, and listening to his favorite music. Some of his favorite authors are Walt Whitman, William Faulkner, Allen Ginsberg, James Baldwin, Raymond Carver, Ray Bradbury, George Orwell, Mario Vargas Llosa, Reinaldo Arenas, Rafael Cadenas, and many others. Lately, he has been primarily interested in reading about dystopic societies, a topic that deeply resonates with the crypto industry.
Since 2023, he has lived in Spain with his wife. He loves the weather, the food, and the people and their culture. They both expect to travel much more within the country they now call home and beyond its border. He hopes to retire with his wife, maybe in a quiet place near a beach, but most likely in a city close to a library and a university with his kids and, hopefully, grandkids.
