Hello,

for an altcoin-Project i want to read in numerous altcoin-Blockchains. They should be up-to-date and include the transactions of the last minutes.. So i installed some coins.. I use a Windows-Computer with quite big ressources ( 8 cores, 16 GB Ram, 1 GBit Downstream, 1 GBit Upstream, Windows Server 2012 64 R2 ).. So i installed worldcoin-qt.exe, megacoin-qt.exe etc.. ( instead of bitcoind because not every coin has it.. ) and use the following commandline:

megacoin-qt.exe -datadir=data -server -rpcallowip=127.0.0.1 -rpcport=1337 -rpcuser=myuser -rpcpassword=mypass

so everything boots up.. fetches the blockchain within 24 hours.. and i can connect on the rpc-port and fetch blocks via JSON-RPC



but: these altcoins do not have all blocks of the network. Their newest block is already 1 - 2 hours old! sometimes they are 12 hours behind.. in the debug-window i can see this on most coins.. as you can see: the coins use very low ressources.. and only worldcoin is up to date... the server-port ( e.g. 7951 for Megacoin ) is opened in Windows-Firewall.. i have like 10 incoming connections and 10 outgoing connections for every coin on the right port... So why can't they speed things up? i don't see any options.. I am not going to ask every altcoin what they think... there must be a general problem!?

so why do they behave so bad for me ( i can not download ) and why do they behave so bad for the network ( i can not upload )?

For some coins I found I had to hunt through 100+ pages of their ANN threads looking for nodes. Often trying all the nodes I could find was the only way I could get them to sync. It would have been helpful if the dev kept an up to date list of working nodes on the OP of the ANN thread.
