Adaptive block sizing means right now it's hard to get money around in XMR chain because it is saturated. However, over the next hour the blockchain will expand its blocksize and this will be less of an issue. Please wait for your tx to be included in the blockchain.
Just wait for your transaction to be included guys. LOL That'll go over well with the real world.
Nice attempt to troll - in fact dakrcoin and bitcoin have fixed limits and are less flexible in that regard. You will notice that soon when everyone is forced to use coinjoin where tons of inputs will meet tons of output which wont fit into every block.
Just on as sidenote, forced coinjoin for every tx will prolly produce way more "bloat" then cryptonote.
"There is also concern this might also enable the adversary to steal collateral payments"
Badly behaving nodes are banned by the network.
Fail by design, banning after something malicous has already been happened.
"master nodes arent untraceable"
Doesn't monero have nodes? Yes? Are they untraceable?
Monero doesnt need nodes for mixing, If you use that argument than bitcoin is also centralized which is of course non-sense because its a p2p network.
"other spenders need to send spends of the same amount simultaneously"
It's all automatic, users don't have to worry about that. User clicks send, and Darksend will wait until there are sufficient sends in the pool. And after the Darksend becomes mandatory (or default option) this won't be a problem as there will be a lot of people actually using the coin and creating transactions, as the coin can actually handle > 5 transactions per block.
Again fail by design, you dont need to wait for someone in Monero to send anonymous transactions.
And once again, Monero can handle as much transactions than drk/btc...
"Masternode centralization problem"
Doesn't monero have nodes? Yes? => "centralization problem"
Nonsene again, of course a p2p network uses nodes thats why its DECENTRALIZED.
But if you use "special" nodes for special tasks with closed source software all hosted at amazon, ovh and digital ocean...its hardly decentralized, i am just waiting for the first reports of abused and confiscated mixing nodes and people losing their money...
