Briar doesn’t make sense to me because you’re trading a central server for a central service… If tor is down, you can’t message. It’s the same POF as cellular, which is insane to me.
It’s also a specific procol, which can absolutely be blocked. I don’t know where this notion that it’s impossible to block tor because it was designed to be censorship resistant came from, but you can absolutely stop people from using it.
It’s not even that hard and there’s nothing end users can do about it if they don’t know how to circumvent it…
It can be blocked, but blocking bridges is a constant whack-a-mole (especially now that they have Webtunnel which, while apparently not as robust as some dedicated obfuscation solutions, is still a noticeable improvement). My bigger problem with Briar is that both recipients have to be online to message, or you have to set up a “mailbox”.
You’re missing the point. Of course tor is decentralized, but the tor protocol can be locked at which time you have no connectivity at all… Your super secure messenger doesn’t work. It makes no sense.
Unless you obfuscate tor traffic, it’s trivial to block it via any number of IDS products. The entirety of public tor exit nodes are publicly available: https://check.torproject.org/torbulkexitlist
Here’s tor exit node blocking in production with 14 lines of bash…
It’s significantly easier than you’ve obviously been led to believe. When it becomes not easy is when someone understands the protocol and understands how to circumvent these measures, but I can assure you that 99.8% of all tor users don’t fall within that category…
Bridges are trivial to use tho. And even if they get blocked too actively, a lot of people in such censored regions have a VPN anyway (although I still don’t have an understanding whether a VPN decreases Tor’s security if used like this.
Briar doesn’t even use a central server, all connections go through tor

TOR isn’t a centralized service, it’s a distributed network.

Being able to be blocked is a completely different thing than being centralized service.
I mean, if users don’t know how to circumvent something, by definition there is nothing that they can do about it.
However, unless this hypothetical censoring country is blocking all encrypted network traffic it is trivial to access TOR via a VPN or an SSH tunnel

tor is decentralized, if someone’s tor server goes down you just go to another.

“the tor protocol can be locked” ?
