Your valid address
MAIA is the acronym of Masked Authenticated IOTA Address. It is based in public MAM channels and always returns the last message.
Starting with version 3, MAIA allows you to define arbitrary fields such as a public IOTA address, an email address or a version of a file. You have control over which fields to create.
MAIA implements a data structure designed to optimize efficiency. Therefore, the first updates will be slower, but do not despair, it's just an illusion ;)
MAIA also allows you to define views, which are transactions that index the field of a MAIA address.
