To be honest,I can't really think of anything right now.Does bitcoin have another purposes or intentions to promote and boost the technological sector other than been a digital currency that aims to eliminate the need for central authorities such as banks or governments.
bitcoin is a currency network.. and should stick to that
however, more broadly.. the blockchain technology can be used for multiple types of data that dont need to be currency based
just think about any IT service that require multiple access points but has one central server holding the data.. then imagine that data server is distributed on multiple continents so that no single IT manager/power outage or facility disruption can take down the data/edit the data.
things like international identity records for border control. instead of relying on one government ID records department, imagine an international ID network that all continents have access to so that the TSA at airports can share information on passports
things like births deaths and marriage certificates can be proven without relying on one country needing to speak to an embassy of another country
heck imagine a game avatar that you can take from one game and apply it to another game. taking your gamer stats with you because multiple games access the gamer network of ID/stats
even in private blockchains of a company. just not having one server but a server per car dealership, bank branch, amazon fulfilment allows data integrity of stocks/assets/product audits where one employee cant mess with the data and power outage at one location doesnt disrupt the network
blockchains purpose is distributed ledgers of proof of data
by this i mean the most critical parts are not the raw data of a transaction, paragraph, record.. but the locked in merkle tree of leafs of hashes that identify and prove linkage to the raw data, and then the linkage of the chains of blocks time stamp that data based on which came first
so not al blockchains need to also supply all raw data of every record. they can have distributed nodes of just the blocks and the merkle leaf identifiers of data (without publicising the data itself)
thus just proving the individual locations that do have their own raw dataset can prove their data was registered at certain dates without having to tell everyone of the raw data itself, and only need to prove it to those directly involved in the raw data need
