Uses of blockchain other than cryptocurrency that just came to my mind, some are already functioning or being introduced:
Decentralized, trustless, uncensorable domains that don’t require kyc to purchase.
Decentralized, trustless, uncensorable replacement for certificate authorities that can’t be hacked as easily as CAs can.
Decentralized, trustless, uncensorable server for small data like pgp signing keys, torrent magnet links, file hashes, static websites, code etc.
Decentralized, uncensorable, distributed way to store archival information or historical records like weather data, government document records, wikipedia edit history, book versions. Anything that shouldn’t change or is in danger of getting censored.
Automated financial markets open to the public through tokenization like stocks, bonds, commodities all settled on chain without 3rd parties.
Trustless on-chain contracts/smart contracts that will execute automatically or can be proven without a notary.
Decentralized, uncensorable, trustless identity system
