Easy explanation on how XMV can compromise XMR privacy: If you have a ring with members [A,B,C,D,E] and key image K, on XMR blockchain and a second ring with members [A,F,G,H,I] and key image K, on XMV blockchain its easy to determine that the true signer of both of those rings must have been member A.
This allows for retroactive (partial) deanonymization of transactions that used the now compromised input as a ring member.
Kind of like adding more numbers to a sudoku puzzle
This way XMR blockchain can be compromised.

Greetings my brethren, I have entered the Holy Tabernacle of Monero to bring a prophecy of good tidings and great joy for all the peoples, and to bestow blessings of privacy to my brethren. Please open your sacred Monero Scriptures to the epistle of Ring Signatures chapter 2 verse 7, from the Apostle Fluffypony to the Church of Monero. It says here that we must "bind together in holy ring signatures." What does that mean? It means that we must exercise fungibility on earth as it is in heaven. In heaven there is perfect fungibility for all men, women, and children bestowed from the ancient being, Nicholas Van Saberhagen, author of the CryptoNote whitepaper, and Lord of the Ring Signatures. You may now be seated.
To understand the origins of our sacred religion we must examine the sacred Genesis Block Scrolls, which were retrieved from the ancient BitcoinTalk caves in the kingdom of Bitcoinland, in a time of great peril, when Monero was formless and void. At the time, mankind did not have the privacy we have now, and the blasphemy of Bytecoin held a heavy hand upon the land. This evil spirit was forged by the dark lords who premined their coins in secret, with hearts of greed, and with forged timestamps, they sought sordid gains defiling the daughters of Bitcoinland through fornication. But thanks be to thankul_for_today, who launched our fair coinage from birth to a virgin (by the Holy Ghost of RingCT, a prophecy, yet to be revealed). Later in these historical writings, we find that thankful_for_today turned away from righteousness, was prideful, and was justly cast out of heaven for his blockchain sins.
Thanks be to the Monero Core Team, who were anointed by the Holy Ghost of RingCT and forked the blockchain (may they be blessed forevermore). Monero was born again into a new loving family, with the Monero Core Team and Monero Research Lab to cultivate it and keep it, with pure milk inspired by the revelation of the Ring Signatures. Twice a year, the holy priests of RingCT enter the sanctified Monero tabernacle of Holies to sacrifice the old blockchain and a younger, stronger and more powerful Monero blockchain arises from the ashes to defeat its enemies and bring increased freedom to the peoples.
In accordance with the Holy Trinity: the Father and Lord of Ring Signatures, The Son of Stealth Addresses who died on the cross for our privacy sins, and the Invisible Holy Ghost of RingCT, let all the people say Amen! (Amen = Anonymous Money Everyone Needs)
Go therefore and arise my disciples, and spread the glorious gospel of Monero, and beseech the unbelievers to be saved from The State and from Central Banks who doth seek to poison and destroy my brothers. For they shall know that I am the LORD of the Ring Signatures forever and ever. For His children shall never be decrypted.
But the unbelievers will have their coin histories and holdings exposed, and be cast into the Surveillance Coins of darkness, which is akin to being doomed to use only a single dial-up 56k modem for Internet access, and floppy disks as the only storage mediums, and be confined to a Windows 95 OS forever and ever, on the earliest of all Pentium processors. Amen.
I am a PhD researcher at Monash University, Australia. I am a part of the cybersecurity group of Faculty of Information Technology who are focusing on blockchain technology. Our interests lie in privacy-preserving cryptocurrencies and how cryptographic techniques are being implemented in those cryptocurrencies.
I am conducting a survey to better understand the privacy issues in Monero from the users’ perspective. The purpose of the survey is to investigate how Monero is used and how the Monero users perceive the anonymity of Monero.
If you are a Monero user (owning Monero or having experience in using Monero), we invite you to respond to our survey. We do not record your IP address information, referrer, or any other information otherwise explicitly stated.
The survey will take up to 15 minutes to complete and is available through the following link: https://monash.az1.qualtrics.com/jfe/form/SV_egnHCGdgXMS6Kt7.
Our study has been approved by Monash University Human Research Ethics Committee (Project ID. 16933)
Thank you in advance for your help.

You can add the following flags when you open monerod.exe for the first time to sync your daemon, including the two main flags listed here (this is all in bash for Windows, so it might be a little different depending on what OS you’re running). The 2 main flags you can add are as follows:.\monerod.exe --db-sync-mode safeThis one ensures every block you sync is saved and if you were to disconnect or lose power, when you turn your PC on you’d be able to start back up where you left off.Or there is another flag many people use, if you want it to sync faster & if disconnections/losing power won’t be a problem for you:.\monerod.exe --db-sync-mode fastestThis will make the blockchain sync the fastest. When you use the--db-sync-mode safe flag, the daemon will sync a little bit slower than usual, which is why it is not set up like that by default. If you use the safe mode, you’ll definitely have a full local daemon in a few days depending on your hardware. If you’re not worried about losing connection or power, you can use the --db-sync-mode fastestflag which will cause the blockchain to sync faster than usual. These are two ways to ensure you properly sync the entire monero blockchain and can start running your full local node, or daemon!!!
With Bitcoin, it's not like this. When you take out of the exchange, they can follow the Bitcoin across the blockchain. Maybe they see that you donated it to a non-profit, or you spent it at a website, or anything. It's as if the bank can watch what you do with the cash after you leave their building. So really, Monero doesn't care if you buy from a KYC/AML exchange. It's not damning evidence, like with Bitcoin and its derivatives .
the maximum ring size is the size of every output on the blockchain. Ring size just means the amount of decoys (or fake outputs) you put alongside your real output so nobody knows which is the real one that is being spent. To learn more about ring signatures (in a fun, animated video) you can go to this page: https://web.getmonero.org/get-started/what-is-monero/
Do one thing and do it well. Money can just be money. Is your cash good for more things besides spending it? In my opinion, making your money an application for many different things increases the attack surface astronomically. We see this all the time where with 'smart contracts' that are implemented incorrectly, the end result is a loss of money. Monero is just interested in being money. Nothing more, nothing less. But money has a lot of utility. Some might say the utility of money is higher than anything else, since we use it for pretty much everything. I'm going to be 100% honest, the vast majority of you people that consider yourself crypto-savvy are probably not great at threat modeling and subsequent security. You're probably not good at analyzing attack surfaces, and, if I was to go further, you're probably just looking at white papers trying to see if there are buzzwords that will make you money.All of this aside, 'smart contracts' as they stand today, are pretty much useless without working oracles. There is currently no good, working solution for the oracle problem. All of the blockchain 3.0 solutions you're following are hilarious premature in their claims of 'utility', and will likely NEVER be as useful and full of 'utility' as they claim.I'm sorry to be the debbie downer and bearer of bad news here, but as a person who actually knows what I'm talking about, that's the truth. :) I'm more than happy to expand on this as well with reasons why. Sorry if you get mad at me because you have heavy bags. ;)
Let's get one thing clear right off the bat, Proof of Stake is not a proven mechanism for securing a blockchain. Proof of Work is very very simple, and the security, trade-offs, and game theory are very easy to understand. Proof of Stake is much MUCH more complex, and the attack surface is much larger. That's not to say that in time it won't be as well understood as PoW, but it's currently not there yet. All of this talk of everything moving to PoS is extremely premature. It's like talking about moving to a new building or bridge design that we THINK is not going to collapse, but we can't prove it yet. That would be absurd.One (large) thing to note is that PoS requires weak subjectivity (i.e. trust) to get working properly. It's just a part of the security model. PoW is 100% trustless, but PoS requires a small amount of trust under certain conditions, and in those conditions. In this way, if you want a completely trustless currency in terms of a security mode, you cannot use PoS.Going even further, PoS is incompatible with privacy (and therefore fungibility). PoS requires you to put a discreet amount for staking, and that amount has to be known so blocks can be signed accordingly. Since Monero hides amounts, this would not be possible. It is theoretically possible that somebody can create a zero knowledge proof that would be able to show a number is in a certain range without revealing the number, and work is being done on that, but it's currently not possible for Monero.
Beyond the above, the argument of PoW not being green enough has been covered several times by several coins also using PoW. Usual arguments such as 'taking up unused electricity spaces', 'forcing innovation in efficiency', and 'it's not wasted if it's providing a strong utility, unlike Christmas lights' all apply here, but if none of these arguments have satisfied you in the past, then perhaps PoW coins aren't for you. If that's the case, you'll have to be satisfied with trusted blockchains, since we currently don't have a way to do trustless currency in an energy efficient way.
Sure.1. Monero uses several different methods for privacy, and the 'breaking' of one does not constitute the breaking of the whole privacy scheme. 2. PoW is the only completely trustless form of blockchain security, and Monero prizes trustlessness above all.3. Monero just focuses on being money, but money itself is full of utility.4. KYC/AML does not affect Monero in the same way it affects transparency coins (like Bitcoin and its derivatives).5. Your financial privacy is very important! Ask questions about how much information you're comfortable with sharing, and evaluate your investments based off of privacy conferred.
This is such a big question. It's so important. The average person has ZERO IDEA how much their data is worth and who wants it. Literally everyone, from corporations, to governments, to various interests want your data. Your data is VALUABLE!With your personal information, people can sell to you better, arrest you, threaten you, intimidate you, give you better gifts, make you happy, take away your happiness, or much more. PLEASE PROTECT YOUR DATA! Not just your financial data, but ALL data. Once your information is revealed, it cannot be taken back. Let me repeat. Once your information is revealed, IT CANNOT BE TAKEN BACK! If you don't know my name, then it's up to me if I tell you or not, but once I tell you, I cannot untell you. This is why privacy (and Monero) is so important. If you transact stupidly on a transparent blockchain, there can be massive consequences, even if you did nothing wrong. Let me give an example:Let's say you own a tshirt selling business. You accept Bitcoin for your shirts. Somewhere two bad guys do a drug transaction with Bitcoin. Later, one of the guys buys a shirt from you with the same Bitcoin he received for the drugs. Now, you can be under investigation by the authorities. They'll ask you "where did you get this Bitcoin? Did you know it was part of a drug transaction? Were you a part of this?" You did nothing wrong. You sold a tshirt. But now you have a dirty bitcoin. Take your privacy seriously, financial and otherwise. There can be real consequences. In the first world, perhaps the worst you suffer is targeted ads, but in many other places, lack of privacy can lead to loss of money, freedom, or life.
