Never heard about Stegos before. But if it works as it claims to be, then it would prove to be quite a revolutionary cryptocurrency. For a Blockchain network to be considered as "the ultimate one" it needs to meet with decentralization, security, and scalability. Most blockchains of today, are secure and scalable but are not decentralized as we thought they would be. Others are decentralized but are not scalable for the whole world to use. There is still a lot of work to be done in order to fulfill said requirements without defeating the purpose Blockchain technology was created for. The Ultimate Blockchain would need to have smart contracts functionality, privacy by default, decentralization, and scalability. From what I've seen, there are many projects that are close to having all of these features. Komodo and NEM are great Blockchain platforms with powerful functionalities that are far beyond finance. They're still undervalued today. But once people realize their true benefits, they could soar in mainstream adoption like never before.
Nonetheless, I'll be keeping a close eye to this new "Stegos" project. Its success will largely depend on the level of adoption from people in the mainstream world. Not to mention, regulations can affect positively or negatively a cryptocurrency project. And if Stegos will have privacy in mind, it may have a hard time with worldwide governments.
That's the ultimate goal. If Blockchains work together, many things could be solved (like scalability and privacy). As it's said, there's "strength in numbers". The more networks are interconnected, the better it'll be for censorship-resistance against oppressive governments and other entities. Glad to know that Waves is working on something like this, in order to make crypto a better place. As of now, it's one of the most undervalued cryptocurrency projects on the market with so many innovative features that are useful for the mainstream world. Time will tell us if this proposal from the Waves project will be successful or not.
