Many more processes could be made more trustworthy with blockchains:
Fair random number generators (eg. for lotteries) – VDFs, such as the one Ethereum is expected to include, could serve as a fair random number generator that could be used to make government-run lotteries more trustworthy. Fair randomness could also be used for many other use cases, such as sortition as a form of government.
Certificates, for example cryptographic proofs that some particular individual is a resident of the city, could be done on-chain for added verifiability and security (eg. if such certificates are issued on-chain, it would become obvious if a large number of false certificates are issued). This can be used by all kinds of local-government-issued certificates.
Asset registries, for land and other assets, as well as more complicated forms of property ownership such as development rights. Due to the need for courts to be able to make assignments in exceptional situations, these registries will likely never be fully decentralized bearer instruments in the same way that cryptocurrencies are, but putting records on-chain can still make it easier to see what happened in what order in a dispute.From Crypto Cities:
