Scalable blockchains are ideal to store immutable data. Immutability implies that you can write data to the blockchain, but you verifiably not change the data, thus making it ideal to store registry entries (such as land ownership) or certificates where authenticity is essential. While the blockchain itself does not enforce authenticity, the incentive of creating a forgery diminishes when you know to get caught eventually. Moreover, in the case of landownership it presents a case of verifying whether 3rd parties have claims to the same land, which is only possible with public and open databases such as the Bitcoin SV blockchain.
