  • From Signal’s blog footnotes:

    Usernames in Signal are protected using a custom Ristretto 25519 hashing algorithm and zero-knowledge proofs. Signal can’t easily see or produce the username if given the phone number of a Signal account. Note that if provided with the plaintext of a username known to be in use, Signal can connect that username to the Signal account that the username is currently associated with. However, once a username has been changed or deleted, it can no longer be associated with a Signal account.





  • Google is disallowing “remote code” in extensions and classifying blocklists (the lists of urls that ad blockers use to know what to block, which are just text files hosted on remote servers like github) as remote code. As a result, any blocklist updates will need to go through the extension review process, which typically takes anywhere from a few hours to a few weeks.

    Google often updates YouTube’s ad delivery on a daily basis. Blocklists must also update as frequently to keep ads blocked on YT. If Google requires that blocklists go through the review process, they can drag their feet and essentially render the ad blockers useless even if they have to allow them to stay in the extension store.
