what can someone running a node do to someone using the node?

You mean to users connected to the node's rpc?

ye

The node could send incomplete tx data, or outright fake data even

Send false fee estimates, causing unattentive users to spend tons of xmr on tx fees (another case of it happened just yesterday - somebody spent 19 xmr in fees)

ye but won't the other people hashing it fix it?

No, we're talking about rpc here: that's where wallets connect

Nodes talk to eachother via the p2p protocol

Wallets talk to nodes via the rpc port

so thats all? the node can increase the fee?

Nothing stops a node from being "honest" on the p2p side and also sending complete garbage via rpc to any wallets connected to it

They can also log any metadata about your connection to them (ip, time, any other detail)

ok, so the rpc also knows my address right?

And there's one nasty attack in which they can fail to propagate a transaction the first time you submit it, so that when you try recreating it the second time you might end up revealing your true inputs if your wallet is not carefully implemented

(If you pick different decoys each time, then the only input(s) in common will be your true spends)

No, the node doesn't know your wallet address

so the node will only know my ip as some data, but can't connect it to my wallet?

Correct

Not directly, anyway

isn't there a way for monero to make it impossible or very hard for someone to fake this data and increase the fee?

Not really

I think the latest release (0.17.3.2) includes a warning message if you're about to make a tx with a fee above a certain threshold

As for sending garbage data or witholding real data, there's not much you can do about it: a wallet doesn't know what's on the chain, that's why it connects to a node in the first place

So the only way you'd notice is by connecting to a different node and resyncing, and noticing the difference

damn, thats kinda dangerous to have a middle man by default

Danilo82, it's not default... people have to choose to run a remote node.

er... not run... use

i mean, running a 50 GB node just to get virtual coins or use an online node

hard decision

is it?

irony

o can't give 50 GB for it

I thought everybody these days has 1TB worth of space.

isnt pruning a possibility? whats the min size for a pruned node

50GB is a pruned node.

i got no coins, i shouldn't even think about using 50 GB for this

Danilo82, what?? How come you don't have any coins?

You better hurry and get some!

well i want to have, no idea how

What do you mean no idea how?

well... i am having difficulty to find a job, can't mine and no one gives me some :T

oh I see

😔 i wish someone gave me 17 million monero coins

Well, they wouldn't be worth much if one person owned 95% of the supply.

then i would just forget the password, and the last 5% would have all the price

if all addresses got created, then it would be impossible to create new wallets?

the addressing scheme i imagine would be changed

that would be a lot of addresses though... do you wanna write a bot to speed up the exhaustion? :]

no

what does monero use to create the hash?

also how can the devs know if all the addresses got created?

i have a more practical question that isnt as easily searchable ... what i wonder is, that given that you can generate a wallet offline... is that true that, lets say that i send xmr to an address that hasnt been claimed yet, if someone generates a wallet and end up with that address, will they receive those funds?

Danilo82, there are more addresses available than atoms in the universe.

or would it be basically burning money

what if God got more atoms in his offline universe?

vaporwave, yes... they'd have access to those funds. But the chances of that happening are unimaginable.

figured so. and, you can always ask God

🤦‍♂️ of course God wouldn't say he got more atoms, the Universal IRS could tax him more

I'm pretty sure God and His people are tax exempt in most states :)

Danilo82, to give you some perspective: lbc.cryptoguru.org

👀 you never know, the laws of physics could change any time

Large Bitcoin Collider... they generate wallets looking for wallets with BTC in them.

184.66 Mkeys/s

There's some controversy about the ones they claim to have found.

This would be much more difficult for Monero too.

The computers would generate the wallet and then have to scan the entire chain.

but one wallet can have multiple addresses

but only one set of keys

and what does that mean

QR codes are so soulless

vaporwave re: generating wallet addresses offline: all addresses exist, the same way all numbers exist even though nobody may have counted that far. Generating an address essentially means picking a number between 0 and 2^256 and calculating the corresponding Monero address

But that happens inside your wallet. You don't have to "write" all the addresses you've created on the blockchain for them to "exist"

An address is empty only because nobody has created a transaction associated with it - yet

Or to put it in a different way: you know a certain address exists because somebody (could even be you) bothered to create its corresponding public-private key pair and sent you the resulting public address for you to transact with. So when you send money to that address, they'll be able to scan the chain and find it (as long as they don't lose the private keys)

As for using up all the addresses: 2^256 ~= 10^77. Number of atoms in the universe is estimates to be ~10^80

So even if you tried scanning quadrillions of addresses every second, you'd barely make a dent in that number before the heat death of the universe
