DMD had PoW during initial release that's the best way to do it because the coin gets widely and fairly distributed because miners need to sell to cover electricity costs. Changing to PoS down the road is a good way to do it and now the next evolution in DMD v4 is quite impressive. There are some worries in US about SEC going after ETH, LBRY and other crypto calling them securities. What's the worry for DMD v4? We are definitely under the radar but will v4 be truly permissionless?
