BTW, someone translated the chaincode that Fett showed Din in the last episode; https://www.reddit.com/r/StarWarsLeaks/comments/k6qay9/translation_of_bobas_chain_code_possibly_reveals/

Most of it’s not very surprising, basically listing Jango and his “son” Boba, but it also mentions the planet Concord Dawn and lists “Mentor Jaste-” (the e is partially cut off) which is most certainly a reference to Jaster Mereel who raised Jango after being orphaned in Legends. It was also the original name for Boba Fett before being retconned into a different person.

Here’s a short summary of the character by Star Wars Explained (3 mins long):
