Speed and cost. It takes time and money to register and maintain the title records. Searching takes time and money. Blockchain just lowers that, supposedly, if they can lower the cost of mining.
Is there any proof that a blockchain is (or can be) more efficient than a normal database?
Seems like every blockchain I've heard about wastes a lot of energy and time to try to make stuff securely decentralized and if we are going to have special authorities anyway the least secure part will be their keys/access to the chain and the decentralized part isn't really true anymore.
But many (most?) counties have already digitized recorded deeds, at least by index... so it's just a matter of logging into the clerk's system and searching for the situs address or APN or whatever's handy and you get the deed history, out of a good old fashioned relational database. How does blockchain improve on that?
