What are your thoughts?

You mean is blockchain capable of replacing notaries? Yes with immutable structure and decentralized nature, it certainly will. The real question is, is the actual market ready to accept blockchain to replace the existing notaries? No. They have a long way to go. Most of these old fucks don't want to get over the traditional nature.
more like the old guys do not want it because they can not control the market like they always do on the traditional market, with blockchain we can do many things decentrally.
blockchain has everything, we can simplify the process by using it. you do not need to waste a lot of resources and time like we used to be when we were dealing with the notary.
