@0x_Ceee It means both chains end up exposed together!
LTC's yearly security budget is currently at $80M
This is only 3 times bigger compared to XMR, so this attack is highly feasible for them to pull off
If LTC can be hit, it also means all PoW chains besides BTC (for now) can be hit!
English

Monero was successfully attacked; XMR is now insecure & centralized
Qubic can rewrite XMR history, censor & double-spend!
Turns out a $300M PoS chain can "take over" a $6B PoW chain! PoS is that much better
The attacks will continue, foreshadowing BTC's fall; PoW is cooked: 🧵
The Full Story:
It all started out in May as a way to optimize profit for the Qubit validators, as they were able to dedicate spare compute cycles to mine XMR on the side (2% of XMR hashrate)
This ended up being so successful that Qubic formalized its decision by June to fully integrate XMR to help fund the Qubic ecosystem. This led to the Qubic mining pool growing rapidly (10% of XMR hashrate)
It was at this point that Qubic started offering additional token incentives for its pool. Attracting more of the pre-existing XMR miners to join. As Qubic was now able to offer 3x the reward of standard XMR pools!
Only after all of this did Qubic publicly announce its intention to "take over" the XMR network!
By late July, the Qubic hash rate was approaching a majority share (38% XMR hashrate) according to Qubic
Qubic itself was framing this as a "demonstration of power" rather than a malicious attack. Calling it a "tech demo" for decentralized AGI computing...
There were DDoS attacks against Qubic starting on the 5th of August, which slowed down Qubic's hashpower accumulation. This counterattack was not enough;
As on the 11th of August, the "selfish miner" attacks began, which allowed the Qubic mining pool to reach a "majority" share of hashpower by the 12th of August:
To prove their control over the network, they claimed to do a 6-block re-org. While orphaning over 60 blocks in the process. Some researchers have disputed this claim. What we do know is that they gained a majority share of hashpower over a 100-block time period. This absolutely does allow Qubic to rewrite XMR's history, destroying XMR's assumed immutability, censorship resistance & trustworthiness over that time period
This also allows Cubic to carry out double-spend attacks, which could potentially defraud people, protocols & institutions out of a lot of money. Which is exactly why most major exchanges have suspended withdrawals & deposits. Because they run the risk of getting ripped off by Qubic if they choose to exploit this vulnerability
The fact that they merely could have carried out such an attack over that time period is bad enough
As of today, the price has dropped significantly & the hashrate has also dropped over 30%... Demonstrating the viscous cycle of a failing PoW system
Qubic is framing itself as an ally of XMR & claims it only wanted to make a point & does not intend to attack XMR again... That this point can even be made in the first place is exactly what is so damning:
Lessons Learned:
The fact that the token incentives for a $300M PoS chain are sufficient to take over a $6B PoW chain speaks louder than words, proving PoW's inherent inferiority! That is what makes this a unique sneak peek into BTC's future, too
Applying the token economics of a smaller PoS chain to fund a "51% attack" on a larger PoW chain is not something I had thought of before. The incentive of free "marketing" might even be enough to pull that off at that scale. As I most likely never would have talked about Qubic otherwise, & look at all of the attention we are giving it now!
All PoW-based chains are vulnerable to this type of attack, because their security budget is so abysmal compared to PoS based chains
The introduction of political narrative also certainly muddies the water, where some might perceive the attacker as an ally instead. Further fracturing the defense effort...
What also stands out is that XMR's security ratio (the ratio between market capitalization & security budget) is actually slightly better when compared to BTC:
XMR = $55M (block reward) x 0.51 (attack threshold) = $28M (security budget) / $6B (market capitalization) = 0.5% (security ratio) (yearly)
BTC: $19B x 0.51 = $9.7B / 2.2T (0.4%)!
For reference & comparison, here is the security budget math for the top 3 PoS chains:
ETH: 542B+0.97B+3.33B x 0.29 x 0.33 = $52.2B (10%)
SOL: 101B+1.15B+5.26B x 0.68 x 0.33 = $24.1B (23%)
ADA: 29B+0.01B+0.7B x 0.60 x 0.51 = 9.1B (31.3%)
It is crazy how much better PoS security really is when compared to PoW. ETH, for example, has 5x the security budget of BTC at 1/4th the market capitalization, with a lower inflation rate to boot!
Another interesting observation is that XMR actually does have tail inflation... Teaching us that even adding tail inflation to BTC when the crisis inevitably hits might also not be enough by itself to defend from an ongoing "51% attack"!
This is all adding to the laundry list of competing interests, responses, factions & incentives at play during a "51% attack" on a PoW chain. We can at least draw the conclusion that when this all finally plays out on BTC that it will be even messier & ever more chaotic than we first thought
Bad Enough:
This was technically not a "51% attack" as the total stake was much lower, somewhere between 28% too 38% depending on whose numbers you believe. While also not fitting the "attack" part of "51% attack", as they did not steal from or censor anyone. This can be seen as more of a "demonstration"
There is conflicting information on the claimed 6-block re-org, as some researcher are reporting that their nodes did not see it. This is also not the type of thing you can look up on a normal explorer, either, as most explorers will only display the "canonical" history. Cyber Capital research was not running a Monero node at that time, either, so I will throw my hands up on this one until more information comes out to clarify this contradiction in evidence
However, Qubic was able to get to over 51% of block production over a period of 100 blocks by leveraging "selfish mining" techniques. This is even confirmed by Qubics' critics. That is, as far as I am concerned, bad enough by itself & represents another type of attack. Gaining control without acting on that newfound power does not negate the control...
That is why I am mostly uninterested in attempting to minimize the gravity of this event by debating overly nuanced technical details. As that quickly becomes another way for us to stick our heads in the sand
Who is Next:
The Qubic community has just voted to target Dogecoin next!
This same playbook can be applied to chains mined with ASIC's as the majority of the hashrate came from "bribing" pre-existing miners using Qubic token incentives
So that means an attack on DOGE & maybe even LTC (merged mining) is potentially on the table for Qubic. We should not expect a public announcement of intent until they are much closer to gaining a majority share, as that is what they did with XMR
Ofcourse, this playbook is not limited to Qubic, so we might end up seeing other chains follow their example by taking over other smaller PoW chains
Solution:
The majority of the XMR community is not going to like my solution: Proof of Stake
The writing is on the wall: PoS is objectively more secure, more decentralized, more fair & more economically sound
There is no good reason not to embrace this new technological reality: Evolve or die
Conclusion:
Out of all of the PoW chains, this could have happened too; XMR is the least deserving of being attacked
XMR is a staunch community of cypherpunks & privacy advocates. Whose heart, for the most part, is definitely in the right place, as they are actively fighting for all of our freedoms, especially our right to privacy! ❤️
That is why I hope they come out of this stronger; adopting PoS will most certainly achieve that. The greatest expression of anti-fragility is to accept radical change when under extreme pressure;
As that is how diamonds are formed! 💎

@Coach_Yac @Invader49er Look what Kyle did to the 49ers his first year. 49er fans are ungrateful as fuck. One year where he ain’t dominating and you start talking like he ain’t won a game

never seen anything destroy a man in a first world country as hastily as social media
most men observed that are addicted or spend a large majority of their life doom scrolling are obsessed with the lives of others because they have such little purpose and zero drive to accomplish anything meaningful in their own life.
how has it come to the point in 2024 that a man dedicates an entire day of his life to try and get photos of himself and then even worse spends hours more of his life trying to decide "which ones to post"
...sitting there waiting for dopamine hits of validation from their fellow NPC's
social media is one of the main vices thats stopping men from being men, keeps them trapped in a realm of impotent and worthless thoughts
its quite sad to see... and even sadder they cant see it themselves, self awareness is a forgotten art
these men...if you can call them that.. the ones addicted to social media in all formats, are often highly materialistic individuals that prioritise women over absolutely everything else as well
--they cant accomplish any greater goals in life against the system so they get stuck in a pitiful consumer trap trying to fill a bottomless pit with transient 'things'
if you are this person and dont want to be, just quit now, theres too much good shit going on in the world to be absorbed like this by the system...too much opportunity, too many fulfilling causes..
and if you find yourself surrounded by these people, limit your time with them cause they will keep you trapped on their plane of existence for eternity
let them band together in misery -- seek mentors, seek education, apply their teachings, become hungry for growth
interesting times ahead in the markets, time to lock in and focus
get off social media, rearrange your attention & your priorities -- start learning, growing and focusing on putting your life on a purposeful path
the sooner you start the better.
that is of course...if you truly want your freedom.
