How to make a specialized blockchain without a shitcoin

Suppose you want to keep track of some form of assets – for example: fungible tokens that represent ownership of a company; or non-fungible tokens that represent items in a complex of games – in a decentralized, censorship-resistance manner.

You can’t “use a database” as many bitcoiners like to claim because that would necessarily have to be controlled by some central entity (which is ok for many circumstances), but you still need to solve the double-spend problem, therefore you do need some form of blockchain.
