If I have a node, can I use block explorers to check my transactions anonymously?
If you have a node - you can just use RPC to get all the info you need (or self-host a blockhain explorer connected to your own node if calling RPC manually is too complicated), no need to use public block explorers.
BTW, how would this work? Doesn’t XMR automatically obfuscate this?
Imagine you have received an output (a transfer) from a CEX. Immediately (well, after 10 blocks) other people start using your output as a decoy in their transactions. After some time, you actually use this output in a transaction. From what the CEX knows (we assume they are bad guys who try to spy on you) there are hundreds (or more) of transactions where you potentially could have spent your XMR, they don’t know which one is the real spend though. Now you go and use the transaction hash to see its status on a blockchain explorer that is hosted by CEX. Assuming they can correlate your identity (e.g. by IP/cookies/fingerprint/etc.), they now know that you specifically checked a transaction that possibly spends the output they sent you. They cannot prove that you spent it, but it would be a reasonable assumption (why else would you check that specific transaction?). Now, on it’s own it doesn’t give them much info (although your privacy already has been partially compromised), as the destination address is hidden as well as the amount. But if the receiving side of your transaction also cooperates with your CEX, and they tell CEX that the amount they received is the same (minus fees) as you withdrawn from the CEX (or even worse, they somehow also correlated this transaction with your identity) they now can be even more sure that it is your transaction (even though they still can’t prove it).
So, Monero is doing its best to protect you, and you still have plausible deniability, but in those very specific circumstances bad actors can be reasonably sure where your money went.
FCMPs will fix that :)
Well, that’s provably false :) I pay for hosting and domain of my instance with Monero, quite sure this is legal. You can prove yourself wrong by paying for something legal with Monero, if you want.
They already try to do that, don’t they? I wish them to have as much success as they had (and have) with banning drugs. They can’t really stop Monero (unless they force people into whitelisted internet, or find a critical bug in the software).
This is not a valid argument… There’s no “medium of exchange” that is accepted everywhere (even US dollar). Zimbabwean dollar is also not widely accepted, yet I suspect you would call it a currency. You can argue (and you would be correct) that it is not widely accepted, but you can’t say that it’s not a currency because of that.
This is an even more invalid argument… How many fiat currencies have failed, how many had hyper-inflation? And yet again I suspect you would call them currencies. And people transacted and saved in them.
I guess in some sense it’s true. But that’s part of a bigger problem. People need to understand that just because some government labels person a criminal, does not mean that they have actually done anything bad or are a bad person. My country considers me, and many more people like me, criminals - because we don’t want to go to a war and die for a Nazi regime… They freeze our bank accounts for that as well (and yes, Monero fixes that). I’m sure you consider me a bad person for that and would rather see me dead or at least my money confiscated, but oh well - I don’t.
This is being worked on, right now stress test is conducted on stagenet and results are being used to improve scalability :)
There’s always an option to introduce L2s, if they will ever be needed, etc. It’s just not a priority right now because in the current state the network can handle order(s) of magnitude more transactions than it has now.
You can sync a pruned node, which take around 70GBs now, that’s less than some modern games. If that ever becomes a problem, a pruned node can sync an even smaller percentage of total blockchain to make it viable for more people to self-host.
With FCMPs we will have a new type of private key, that you can share with a remote node to scan the blockchain for your transactions, without a significant loss of privacy :)
Well, I guess this argument is valid (just as much as it is valid with other cryptocurrencies). But you can always fork. People didn’t like where BTC was going, BCH was forked. If people won’t like where XMR is going, XCH (or whatever) can be forked :)
Dunno, seems quite refutable to me 🤷
