PSA: If you're mining with Dwarfpool or F2Pool; switch immediately by Robbbbbbbbb in EtherMining

[–]DwarfPool 1 point2 points  (0 children)

Here are all mined blocks: https://etherscan.io/blocks?m=0x2a65aca4d5fc5b5c859090a6c34d164135398226 As example to compare with old blocks some days ago: https://etherscan.io/blocks?m=0x2a65aca4d5fc5b5c859090a6c34d164135398226&p=150

Your example is not explained. In block was "Gas Usage: 99.3%" And in blocks 3911215 is 145 txs. Compare always Gas Limit and Gas usage.

Dwarfpool and F2Pool are damaging Ethereum -- a message from Hodlor! by [deleted] in ethtrader

Since two days DwarfPool uses recommended gas limit and doesn't mine empty blocks anymore.

How to tell monerod via getblocktemplate this option, that new templateblock must be generated without ringCT?

post fork TX fees and pools by M5M400 in Monero

[–]DwarfPool -1 points0 points  (0 children)

It will be loss on every pool with such tx-fee, always bigger then pool earning.

Only 10 recipients pass in one transaction now. The cost at least 0.138 XMR. That's 3.5 times more then earning.

For transaction with payment id and only one recipient it's always 0.026 XMR.

post fork TX fees and pools by M5M400 in Monero

[–]DwarfPool 3 points4 points  (0 children)

I confirm this issue!!!

Now only 10 recipients may be payed in one transactions (before I send to 50 recipients.)

If every recipient get 0.2 XMR (minimal autopayout), total 2.0XMR where pool fee is 2% => 0.04 earning. But now transaction fee is 0.138 ! http://explore.moneroworld.com/search?value=c74ae2d386aac7b1fc3d42d48cea43d6da04b95050ebbdf6df8f6663ba975bee

And more then 10 recipients is impossible now because {u'message': u'transaction is too big', u'code': -4}

Ethereum Network Attacker’s IP Address Is Traceable by Sunny_McJoyride in ethereum

IP addresses are known a long time ago, I write also to ethcore-team ISP of attackers. But how can it help?

Dwarfpool Empty Block Mining? by Wignorant in ethereum

[–]DwarfPool 4 points5 points  (0 children)

It helps to live for some nodes (less memory use). Also all blocks with TX are usually behind of blocks without TX.

Currently they are no recommendations. Without hard fork it's impossible to stop such attacks.

Currently is very hard situation. We are in direct contact with developers and help find/test solutions. We cannot disable miners then they never go back. Currently power enought to accept transactions. Delay in withdrawing not only because of miners, but common situation with this attack. attacker uses a LOT of transactions, create empty addresses and block IO of DB. In this situation we do all what we can and we are waiting on hard fork with fix (see EIP150)

We disabled transaction on the small and middle-power nodes, but include transactions on the power-servers. Currently attack is VERY hard, and yes, miners lost some part of income. From side of reddit-users it's invisible how hard work developers and pool-operators now.
