The initial idea was to make pow alg adjustable. Why devs just can't fork from scrypt:2048 to scrypt:4096? It will cause the same effect to multipool and fpga/ASIC mininig. It will help to gain time for Lyra2 implementation.
Yes, there is a mandate of Vertcoin to fork to higher 'n' of the scrypt-n algo when the ASIC/FPGA is out. Well, the scrypt-n FPGA is finally here now. I doubt the devs know about this. They are busy with the Lyra2 implementation and they have not come into this forum nor the reddit (they have not posted anything) for a long time. Perhaps someone who has a 'direct line' to the devs can let them know of the new ASIC/FPGA development.
