> All the existing models I know of for making money off developing a blockchain involve some form of centralization. Either centralized mining (premining, ICOs) or breaking decentralization entirely (SegWit, Ripple). Nano (née Raiblocks) uses a block lattice where each transaction from an account (accounts are first class citizens here) is appended onto a previous one, and only when accounts interact is there consensus required. Nano uses a combination of PoS and PoW (called Delegated Proof of Stake) to secure its chain. While in theory this is less distributed than blockchain (nodes elect delegates who actually perform the updates), in reality Bitcoin already is a network centralized around mining pools, so IMO dPoS openly acknowledges the centralization that already exists.
