Lets change algo to scrypt-n
and merge mining with VTC
No, just no. Scrypt-N is even less efficient then scrypt. It is also not anymore secure then scrypt. There are no advantages going that direction.
There will be an official response from the developers regarding this in detail, with that being said this is my personal response.
In terms of any hashing algorithms being more secure, that is more myth and marketing then fact. In fact some of those present their own problems in terms of both security and the potential for botnets after analysis by our developer. Basically, they present some major security issues. In addition some of these new algorithms are literally hacked together, they seem power efficient because they are not optimized. Good hashing algorithms, which scrypt is one, generally have the same level of security, and the same vulnerabilities. Scrypt is actually a secure algorithm, there is nothing wrong with it, other then a significant amount of irrational FUD around scrypt ASICs that is prolific right now. Despite the fact that many of the scrypt asics have not made an appearance, and will likely be gradually be introduced into einsteinium's network. The reality is the advantage to ASICs, is actually security.
In terms of efficiency, some may be more power efficient in terms of GPU mining, that is not mean they are as efficient as they can be in general, and as I stated before, a few of them present their own problems in terms of security. As it has been pointed out, is ASICs are more efficient then GPUs no matter the algorithm, and there is a point where we will need to transition to that form of mining at some point. With that being said, as predicted, it would be needed at a certain point in our life-cycle, especially considering the halving schedule.
I would also not confuse investors with GPU miners either. The two groups are not necessarily the same. We see no reason to change our algorithm at this point. Essentially, it would just be a gimmick with no real advantage.
With all that being said changing the algorithm, and implementing such a large fork can present significant risks. This could range from outright killing the coin, the loss of previous coins, or something else. Litecoin laid out one, the biggest risk is it presents the risks of essentially creating a new coin and two separate forks. In this way forking the coin with a new hashing algoritm presents is a significant security risk, and one with no guaranteed rewards. Keeping the algorithm as is, ups and downs included, at least insures we will not see those risks that are introduced through a new algorithm change, which is in many ways, a gimmick, and one that can introduce major issues.
It is not likely to happen to fork to a new hashing algorithm.
