hey, does merge mining some other coin work with p2pool?

Last time I knew, no. p2pool needs to switch from a hash to a merkle tree root for some value I don't remember somewhere in the header, like Tari and TF do.

thanks, I vaguely recall it needed a change.

New GUI XMRIG+P2Pool miner, Gupax

How much does it help for decentralization to mine P2Pool using a remote node? Does the remote node still control the hashrate?

Monero node is ultimately controlling everything

But if node owner will try any funky stuff, p2pool will start to complain a lot and spam lots of warnings

also, I don't think any single node can handle enough connected home miners to get any significant % of the network

it must be 10k and more connections

yeah I don't think epee is efficient enough for so many connections

OpenLDAP has been tested to at least that many high volume connections...

even if some node gets 51% of the network through p2pool and tries an attack, all honest p2pool miners will see it in their logs immediately

so it can't be done stealthily

as soon as a miner gets serious than just run a coupls PCs with gupax, they'll start thinking about their own node

*more serious

hyc btw some p2pool miners connect 5000+ miners to p2pool directly and it works

using libuv right?

yes

<sech1> "even if some node gets 51% of..." <- Mmm not sure, if this actually catches on and hundred of thousands of non tech-savvies start mining, they may not care enough to change their node same way they didn't care about switching away from minexmr

or certainly won't react immediately (who checks their logs?)

But all the other tech-savvies will see it in their logs and alert everyone

sure, but how did that go for minexmr

it's an improvement nonetheless, but perhaps it should make users run their own node by default

minexmr didn't do 51% attacks

true but if it did would people have even cared enough to swtich?

I'm not sure, we are talking about many thousands of individuals, not large scale farms

individuals pay a lot less attention/care

oh, I totally forgot about one thing

all blocks found on p2pool are broadcasted to all p2pool nodes

* of individuals (with minuscule hashrate each), not

so you can't start mining an alternative chain in secret even if your node has 51%

because all your blocks will be broadcasted

it takes one honest p2pool node to prevent this attack

what? so p2pool can't act maliciously?

malicious node can still mine empty blocks

for example

and orphan all non-empty blocks

yes, p2pool architecture works like this: p2pool node finds a block -> sends it to other p2pool nodes -> they all submit it to _their_ monerod

yes but why I couldn't mine in alternative chain if it controls the hashrate?

because when you find a block, it gets submitted to other Monero nodes

so it becomes the main chain

oh!

so while they can create the blocks, they can't submit them themselves like a regular pool would?

no, block template creation and submission is done by p2pool nodes

Monero nodes only provide transactions to mine and some crucial data to build block templates

like current height, previous block, current block size etc.

ah got it, but why it takes a single honest monerod to prevent a chain split?

* single honest node (not sure monerod, * monerod or p2pool one) to prevent

* single honest node (not sure if monerod, * monerod or p2pool one) to prevent

>sends it to other p2pool nodes -> they all submit it to _their_ monerod

at what stage would a malicious block fail? how would an honest node detect it? and what majority would the attacker need to control in order to prevent an honest node from detecting it?

* > sends it to other p2pool nodes -> they all submit it to _their_ monerod

at what stage would a malicious block fail? how would an honest node detect it (and prevent its submissions) ? and what majority would the attacker need to control in order to prevent an honest node from detecting it?

it's not a malicious block, it's an alternative chain

if it gets submitted, and it has more PoW, it just becomes the main chain

"malicious" part is when an attacker doesn't submit it until the attack is over
