<UkoeHB> "maybe I'm misunderstand somethin..." <- for TXO: entire set of unspent coins which can be used by future transactions

IIUC it's outputs + key images in Monero's case

* for TXO: merkle root of the entire set

Hi guys, I would like to ask some questions about website getmonero dot org

<cryptoswpz[m]> "Hi guys, I would like to ask..." <- Never ask to ask. Just ask.

My grandson plowsof taught me that

ArtemVorotnikov[: does the state root actually need to be in the header? I can see how, if you have a trusted state root, it could be used to validate output queries from remote full nodes (assuming those queries come with merkle membership proofs). Is the idea that a light client could sync just block headers and get a state root without downloading the actual state, and then at least know that a certain amount of work was used

to produce that state root?

I just noticed that one of the swap services on the site has stopped its work, but nevertheless it is there, I would like to propose to replace it with a swap service in which I work Head of BD, is it possible?

UkoeHB: correct

cryptonote has a weird definition of block header, because block id = keccak256(header + txroot + num_noncoinbase_txs)

if we discuss state root, then it also should be committed into header chain, that is block id = keccak256(header + txroot + num_noncoinbase_txs + state root)

ArtemVorotnikov[: btw I wrote this sketch of how a monero light node could work with the current protocol design monero-project/research-lab #69

pretty much academic though, quite a lot of work for that

cryptoswpz[m]: please open an issue on github github.com/monero-project/monero-site

note that we don't list services that aren't reputable / known in the community since we had issues with scammers in the past

btw when I say 'state root' I really mean 'unspent outputs + all information required for processing future blocks', in Monero's case that would mean parts of transactions too?

* parts of past transactions, * transactions (sigs) too?

ArtemVorotnikov[: you don't know what outputs are spent/unspent, so you need to know all outputs. Plus any output may be used as a decoy in anyone's ring signature, so they are all 'needed' to validate future txs.

so outputs + key images

And you need to know all key images to check if future txs are double spending

* so all outputs +

yes

* so unspent outputs = all outputs + key images

right

Hello everyone, I am a noob in cpp/cmake/monero, and trying to compile it on my system (OpenSUSE tumbleweed).... (full message at <libera.ems.host/_matrix/media/v3/do…9cf2dcd0c3ad0de09972eca12a41c72bd1e>)

Debayan Sutradhar (rnayabed): do you have the static version of boos installed? (It sounds like you only have the shared objects.)
