ZooKeeper (zk) has consistently remained focused on adding features to its privacy and scalability offerings. A radical overhaul and the creation of a completely original system might hold great promise for the future. However, given the current stagnation of system innovation in the #BTC era, the all-purpose expansion strategies of zk-based tokens like #zcash and #strk are clearly attracting capital investment. Looking at the Monero and zcash white papers reveals that zcash has begun using the term "Decentralized," just like the #ETH white paper. It is precisely this "Decentralized" approach that has narrowed Bitcoin's path of peer-to-peer, decentralized technological innovation.
