Monero, a cryptocurrency celebrated for its privacy features, recently faced a scare that put the entire community on high alert: a potential 51% attack. After the game, the team and situation was well-managed. It exposed serious vulnerabilities in blockchain technology itself, raising critical questions on the security of decentralized networks. BlockchainShock tracks what happened and explores why it matters. It looks at the future consequences of this move for Monero and other privacy coins.
Understanding 51% Attacks
A 51% attack occurs when a single entity or group gains control of more than half of a blockchain network's hashing power. This overwhelming control gives them the opportunity to change the rules of the blockchain, risking chaos and millions in investor losses. It’s really important to clear up what a 51% attack can do and what it can’t.
The Silent Takeover Explained
A successful 51% attack doesn’t automatically put your coins in an attacker’s hands. In many cases, they cannot reverse confirmed transactions that have already been finalized on the blockchain. The biggest risk is in the attacker’s ability to control the sequence of incoming transactions. They can block politically-charged transactions from being confirmed. This censorship can stop network transactions and compromise the trustworthiness of the network. For instance, they can black out competing miners by disallowing them to add blocks on the chain, thus rendering them inactive.
Economic Consequences of a 51% Attack
The greatest risk of a 51% attack is the loss of confidence in the cryptocurrency. If users do uncertainty about the network’s security, they will almost certainly dump their tokens. This sudden mass selling can lead to the price crashing. This “dumping” effect can be catastrophic for the cryptocurrency’s long-term success. In 2020, Bitcoin Gold suffered a major hack. This 51% attack let hackers steal more than $18 million from the blockchain via double-spending. It’s a chilling counterpoint to the theoretical legal harms in the world of finance.
The Master Plan Behind the Attack
Malicious actors typically initiate 51% attacks to drain value from the blockchain network. This could involve double-spending their own coins (spending the same coins twice) or manipulating the network for other financial gains. CoinLaw really hits the nail on the head here. Here’s why whoever controls that much mining power would be better off mining legitimately than by deploying a malicious attack. But sometimes the incentive to take advantage of such a weak network is just too good to resist, particularly when the possible benefit exceeds the risk. Unbeknownst to them, however, the Qubic network was still using its hashrate and economic incentives to try to mount a network takeover of Monero.
Community Response and Resistance
What we saw from the Monero community when faced with this attempted 51% attack was a full, fierce and admirable reaction. When Qubic announced its intention to replace the entire network, the community mobilized. So, they came together to track what was going on, and to take steps to prevent it. This meant working together to ensure that no one organization ever took over more than half of the network’s hashing power. In the end, the Qubic mining pool failed to gain market share. This decrease occurred just as the community learned what they really planned. This is an excellent example of how an organized and active constituency can successfully protect a decentralized network from overreach.
Vulnerabilities of Privacy Coins
Privacy coins, such as Monero, provide additional levels of anonymity than other cryptocurrency assets, such as Bitcoin, which are more transparent by design. This creates a whole new set of challenges, especially when it comes to security.
Why Privacy Coins Are Particularly Exposed
Monero, with its focus on privacy, shares a common risk factor with other blockchains: a weak security budget. The security budget is the economic incentive to secure the network against attack. High incentives to mine or validate transactions indirectly incentivize bad actors. This makes it simpler for them to amass the necessary hashing power to carry out a 51% attack. The latter is the case, as cost of exploitation is lower than expected profits from exploitation.
The Impact of Market Dynamics
Monero has fallen 5% over the past two weeks. A number of factors, like the typically overall general market conditions, may be responsible. Whatever the initial cause, the threat posed by the 51% attack scare is important to heed. In short, bad news and bad feelings typically go hand in hand with price drops as investors get gun-shy.
What Transpired During the Incident?
The failed 51% attack on Monero this past September was a wake-up call to the cryptocurrency community. This made clear the continued threat from malicious actors, as well as the need to keep the network decentralized and secure.
Key Events Leading Up to the Attack
The whole drama started when the Qubic mining pool proudly proclaimed that it wanted to take over the Monero network. Sergey Ivancheglo ran up an attempt to take over the project with his forked. He accused Qubic of attempting to “stir up controversy” for its “sham cryptocurrency.” This announcement sent alarm bells through the Monero community, and they mobilized to act quickly.
Reactions from the Crypto Community
The crypto community answered with a measured apprehension but a fierce resolve. This year, dozens swarmed to show their enthusiasm for Monero and promised to provide an effort to protect the network from the attack. Gavin Andresen, then chief scientist at the Bitcoin Foundation, called attention to some speculative code written back in 2012. This piece of code would automatically reject the attackers fraudulent blockchain and help bring the Bitcoin network back to normal operation in a matter of hours. This does not absolve network developers from having contingency plans like this available to soften the blow of a 51% attack.
Market Reactions and Trends
The failed 51% attack on Monero raised considerable alarm at the time, including its immediate effect on market sentiment and trading activity. Though the network was able to withstand the attack in the end, the incident was a clear reminder of the risks that came with cryptocurrencies.
Whale Sales and Foundation Moves
Although there's no concrete evidence of widespread "whale" sales (large-scale selling of cryptocurrency holdings) directly triggered by the attack, it's plausible that some investors may have reduced their exposure to Monero due to the increased perceived risk. Keeping an eye on rapid on-chain movements and large dollar volumes transacting can help flag potential whale activity.
Surge in Institutional Demand
Yet the incident did not lead to an increase in institutional demand. The implications of a 51% attack are much fewer than the digital currency itself. Trust in the network would be lost, causing a catastrophic price crash as everyone would try to sell their assets at once.
Technical Analysis and Future Predictions
Examining Monero’s technical indicators can give you important hints as to where the price of this cryptocurrency is headed and how healthy it’s really is.
Patterns Indicating a Potential Breakout
So as long as no one person or organization can control more than 50% of the mining power, the network is secure. With two or three pools still controlling 80%+ of Monero’s hashrate, this has been a persistent issue for Monero. The pool pledged not to exceed a 40% cut in its long-term use.
Implications for Investors
For crypto investors, the Monero 51% attack scare is just another reminder to diversify and manage risks appropriately. No cryptocurrency is immune from attacks. To guard against losses that can’t be avoided, diversify your investments among various asset classes.
Insights and Conclusions
As it turned out, the Monero 51% attack scare served as a good reminder for the entire cryptocurrency community.
Why Bitcoin Remains a Safer Long-Term Investment
While Bitcoin could be attacked in several ways, the large network size and widespread adoption powerfully protect it from a 51% attack. By comparison, smaller cryptocurrencies like Monero are far more susceptible. Getting enough hashing power to effectively control the Bitcoin network is prohibitively costly. This significant expense proves value enough to keep up malicious actors from targeting it.
Advantages of Volatility Resistance
Cryptocurrencies that fight against volatility are able to withstand large price movements. They are immune to the whims of a stock market, market sentiment, and other external or market-driven events. Bitcoin’s relative stability compared to every other cryptocurrency gives it a further leg up as long-term investors’ preferred store of value.
Final Thoughts from CoinLaw
The recent unsuccessfull 51% attack on Monero underscores the paramount importance of security through perpetual attention. As a whole, it reaffirms the necessity of grassroots engagement to win freedom-retaining, decentralized networks.
Kathleen Kinder's Perspective
In her testimony, Kathleen Kinder’s expertise underscores the importance of doing more to proactively prevent attacks in the first place. But unless the blockchain’s community adopts certain structural reforms, then “this can happen again.” Butual changes you would make to the mining algorithm. Instead, you can just raise the block size or find some other way to make the network more secure.
Importance of Staying Informed

Yet a 51% attack is a very real threat to any fledgling blockchain lacking significant diversification to its hashing power. This revelation prompted to explore alternative avenues. Keep in mind, an actor with immense mining capability stands to make more by playing by the rules. It’s more rewarding than attempting to censor transactions or perform a double-spend. On Sunday Sergey Ivancheglo took the credit on X (formerly Twitter) for the takeover attempt. He disclosed that the Qubic mining pool he operates is currently under a DDoS attack. On Saturday, January 5, 2019, Coinbase noticed a massive “deep chain reorganization” on the Ethereum Classic (ETC) blockchain. This disruption even involved a rare case of double spending.
