Why did EOS change its name to Vaulta?

Answer: Because it wanted to change its 'disguise' to make everyone think it's a brand new project, just like it secretly put on an invisibility cloak and reappeared in the Web3 banking track, while still being the same EOS, focusing on a mysterious operation of 'guess who I am.' However, the EOS Foundation has been continuously building and has done a lot of work; if the coin price can take off, it would be considered a successful name change.
