I'm not sure if this exists or not, but is there a database storage system that is immutable, whereby it cannot be erased or be altered without someone knowning? Use case would be for public data that should not be manipulated or erased at all. And if there are any modifications it would be known. Also the data would have to be redundantly stored to prevent data loss or deletion.
Is there a service that lets you host any type of data/records in this decentralized manner?
