Precies. Alleen door in te spelen op de nieuwe releases kan je nog proberen wat extra te pakken.
Minen met gpu = dood --> asics rulen --> decentralisatie is foetsie. Het is tijd voor nieuw bloed, en een beter besef van wat centrralisatie teweeg gaat brengen.
Om een idee te geven hier wat cijfers van BorisTheSpider van vertcoin over te grote pools;
Some of you may believe, because it's called a 51% attack, that you need 51% of the network hashrate to do it. Not so - it's just that if you have 51% of nethash you can _ALWAYS_ do it. If you have less, you have a smaller probability of accomplishing it, in proportion to how small your hashrate is (ie. it's incredibly unlikely, but you could in theory do it with 1kh/s).
Let me put some figures on this for you:
With 25% of nethash (which is what bitcrush and vertco.in both have at present), the probability of an attacker successfully orphaning the commonly used 6 confirmations is about 5%. It rises exponentially though, and if these pools grow to 30% of nethash, they would have a 13% chance of accomplishing that attack. Let them get to 35% of nethash and it's a 28% probability.
On the flip side however, it doesn't take a massive reduction in their hashrate to vastly reduce that probability - for example, with 20% of nethash a pool has only a 1.5% probability of accomplishing such an attack, and at 15% of nethash it's down to a much more acceptable 0.2% probability.
The other issue is, two big pools could in theory collude. I am personally satisfied this is no issue here, because I know that Bushido runs vertco.in and is not about to attack his own coin, but it still is an issue, and we shouldn't need to trust anyone here - the whole point of this is to make things trustless and secure by design.
