Title: BBQ and mincoin under threat of 51% attack Post by: xan_The_Dragon on April 27, 2013, 10:17:42 PM Pools with 51%+ of market share Mincoin- vircurpoool 13.14mh/19.646mh =66% of total hashrate bbqcoin-http://ub3rl33t.com 21274.44kh/21517.39kh 98.8709% of total hashrate Title: Re: BBQ and mincoin under threat of 51% attack Post by: perhan007 on April 27, 2013, 10:21:17 PM If the BBQ pool has almost 100% of the hashpower, its members will get every block anyway so what should be attacked there :D

I alone am solo mining at 6Mh/s. Something isn't updating right somewhere.

I alone am solo mining at 6Mh/s. Something isn't updating right somewhere. I'm solo mining, too, and picking up a block now and then. It doesn't look like the chain is being completely dominated. (But then again, I may not know enough to tell, at this point.)

Title: Re: BBQ and mincoin under threat of 51% attack Post by: nethead on April 28, 2013, 05:16:16 AM To 51% a chain you need to modify the wallet client and solo mine, so that you can merge "your" modified chain to the original one to add the invalid blocks. (also you need more than 51% hash power of the network to do so)
The pool is actually solo mining with your hashes (and then spreading the coins). So the threat of 51%'ing it is real only if the pool operator has a modified client and uses your hashes to do it. EDIT: Then again, if the pool operator had a modified client, the blockcount shown there would be different than the real blockcount (EDIT3: and you wont receive any coins that you mined in most cases) EDIT2: When a new coin comes, and there are only a few or only one miner hashing, he/they has/have more than 51% of the total network hashrate, and the coin doesnt die. Else every coin would be dead by the first day of its existence |
