I admittedly don't know what a moon shot is. I'm not sure if that's an application or an NFT. However, the technology today that is really exciting is figuring out how you scale up these networks to allow transactions to take place at a fraction of a penny, and what type of economic activity can happen if that becomes a reality in a secure way.
I can't speak to other blockchains. Helium was mentioned before. I'm not sure what that is at a tech level. However, I think that scalability and having the right to transfer something at a fraction of a penny anywhere instantaneously is very important. At the same time, I think that a lot of proposals are going to be developed in the coming years for financial institutions to figure out how they can leverage this technology and these open layers to digitize some of their current activities or use it for a faster or more efficient settlement, while respecting that they are going to need privacy.
Zero-knowledge proofs are something that speak to whether you can transact in a way that a bank does not expose what that activity is to the open public. Can you transact in a way so that people can't see what it is, but can prove, verifiably, that they have a certain set of reserves and that a certain trade took place? That is developing very much in the background, and it will be a big part of the next few years. It's scalability and financial institutions leveraging the technology in a way that benefits their existing systems.
