selsta: Will do

<kayabanerve[m]> "I'm assuming a monero-wallet-rpc..." <- Yes, outputs that belong to this wallet. This line of code exports the outputs in the form of hex string: `const outputsHex = await viewOnlyWallet.exportOutputs(true)`.

For clients, do I still need to scan the whole blockchain to see if I have received payment?

Or is there some solution to not neeeding to scan the whole blockchain

You have to. Though you can give your secret view key to someone else to do it for you. But someone has to do it.

Well, if you wnt to check ONE payment if you're given a txid, technically you can scan just that one.

There's a feature that does it on typical block explorers. I forget what info you leak exactly, I think you do leak your secret view key too. Must do.

But in the general case, your secret view key is needed to scan every output.

Soon, that scanning will get something like 30% faster (I think) for 99% of outputs, but still need to scan it all.

Even something like mymonero, they scan the whole chain wiht your key (which you give them). So it seems quick, but the work is still done elsewhere.

Now, if you know you cannot possibly have received anything in some particular period of time, you can just skip scanning the blocks in that time.

If you DID receive something, it won't be found.

There's a system to scan just a few txes in monero-wallet-cli, not sure how to use it in practice as I didn't write it. But if you have a set of txes you know are the only things you got, that'll be lightning fast.

But these are special cases really. General case, need to scan it all.

Wait. This is -dev. Ask in #monero, assuming it wasn't a technical question abut writing scanning code.

Fwiw, gui added a "scan tx" feature

That's nice. I'm unsure how to tell it not to scan the rest.

ie, you're at block 1e6. The chain is at 1.5e6. You want to scan just one tx in the that range

Guess I should go read the source.

read the docs

For mobile clients and ux it seems that this fuzzy message detection strategy would be advantageous

Not sure if previous messages got sent before this one ^

Looks like not. Your previous line was "Or is there some solution to not neeeding..."

resending:

@moneromoo there seems to be some research in fuzzy message detection, which is why I was checking

So someone powerful will scan the blockchain for you and returns a percentage of false positives

Ah. I believe JAMTIS will allow something like that.

This will probably end up in monero at about the same time as Seraphis.

Is there anything that is lost in terms of privacy with Jamtis?

read the monero-research-lab archives

it's all been discussed heavily

okay thank you

Guest76: Do you know this Reddit post and thread already: old.reddit.com/r/Monero/comments/v4…_view_key_method_is_problematic_for

rbrunner just checked it out and the github one of the posts links to, is very helpful. Thank you very much

I want to write code on twisted ecc so tried to understand monero implementation but damm i am not getting it so can anyone here help to connect the theory formula for tecc and the code implementing it.

You’d be better off writing a slow version from scratch using the stuff in ch2 of ztm2

No i don't want slow one if i wanted i could have written it from there, than there would have been no need for asking.

Is your problem understanding the api or how the implementation works?

If you aren’t trying to do anything with Monero, idk why you’d be looking at the Monero internal crypto library. Libsodium is a generic library better suited to arbitrary projects.

And probably way better documented

moneromooo: any idea what to recommend to this person? monero-project/monero #8477#issuecomment-1202042559

first they had their daemon misconfigured but now not sure what it means if it fails after 30min

I commented.

Hi guys. I just created this report on github. I could reproduce it. Not sure if this is known, or I indeed found an issue.
