The attacks tend to do something like "build a chain based off Dinkycoin's previous blocks, but don't publish it until a later date". The difficulty changes can't help because the chain doesn't know about the attack until the attacker publishes a longer chain.
- bouncycastle 8y agoYes, of course! And once the damage has been done, it's even harder to reverse. Perhaps if Dinkycoin's devs are fast enough, they could release a fork to undo it?
- setr 8y agoAs long as the attacker maintains 51%, he can eventually just repeat the attack, regardless of the number of forks.
- bouncycastle 8y agoOoohchie, yes indeed!
- jki275 8y agoYou change the POW function in the fork to eliminate the attack.
- bouncycastle 8y agoPerhaps if the attack was done using ASICs, but when done with GPUs it can be repeated indefinitely.

- jki275 8y agoYes, you have to address that kind of attack differently.
