In the seventh session of this 12 part series, join status' core contributors as we discuss and debate to which degree we uphold our principles, how we can improve our performance, and what we're adding to our Wall of Shame.
Privacy is the power to selectively reveal oneself to the world. For us, it’s essential to protect privacy in both communications and transactions, as well as being a pseudo-anonymous platform. Additionally, we strive to provide the right of total anonymity.

[Michael] Privacy hasn't been around for millenia, it's modern.
-- Oskar disagrees :P what do you mean by this more precisely?
Define privacy:
Begin general discussion:
[Michael]
"Privacy is dead. Get over it". I chose to be a "glass man".
[Barry]
This is largest public deployment of cryptography in history.
[Corey]
Pushing forward the boundaries of cryptography as it pertains to privacy.
[Michael]
I have a fear of blockchain data being indestructible.
[Iuri]:
"The right to be forgotten" brings challenges. Can be misued. Should it be possible to remove data?
[Anna]
Can separate between what the app can do, and what can happen in the real world (screenshot or sharing verbal information). But if I'm talking to a friend in a room, I want to be sure that no one is listening to that conversation. People will reveal based on what we share, and the space we are talking in.
[Ricardo]
Algorithms are safe, for now. I could collect all the data and decrypt in the future.
[Michael]
Example: Tor. Government collecting data and running traffic analysis.
[Ricardo]
It's not guaranteed that whoever sends the message is who they say they are. It may be possible to decrypt, but it may never happen.
[Barry]
Possible that an actor (nation state) can already decrypt. They wouldn't let us know.
[Oskar] Important not to be overly paranoid. Given what we currently know, it seems like this current representation is safe. If a nation state wants to target you specifically, there's not much you can do.
[Ricardo] That's important. Distinction between small individuals (hackers, criminals) and nation states.
[Corey] If someone wants to attacj you, then can. It's about motivation and resources. Need to make it as difficult as possible, so they don't have motivation or resources.

[Oskar] Mossad vs non mossad

[Michael]
What do we feel strongly about? What guarantees should we make?
[Corey]
That your funds won't be stolen.
[Ricardo]
That you're not going to be censored.
[Oskar]
Some guarantee around darkness. What the theortical leakage is.
[Graeme]
How is darkness measured?
[Oskar]
There's been some work in Tor and other networks. There should be metrics or research.
[Barry]
Use of our mailservers - central points within Status right now. Is there a privacy concern there?
[Oskar]
It's a trusted form of relationship.
[Ricardo]
In future, you'll subscribe to an address so the mailserver knows you want a message.
[Michael]
How will that change as we scale? Does the threat model change with the size of the network increasing?
[Oskar]
Depends where the data lives, and the specifics of how we implement it.
[Graeme]
Clearest one - amount of data used to send a message. The more "dark" the more resources it takes. More resource therefore equals darker? Adam / Dmitry knowledge on this topic.
[Michael]
What are we doing to support:
[Corey]
Working on allowing you to spin up miltiple identities. You can choose what to share with whom. Whenever you enter a chat, you join as one of your identities. That should allow you to have better options and settings. Because we're separating the keys, we're separating the ability to see funds associated with public chats. That's a privacy gain.
[Ricardo]
Create a new type of identity that starts up every 15 mins, or every message, to make things anonymous.
[Michael]
Make a user setting to choose how long their data is retrievable? Is that doable?
[Ricardo]
I think yes, if you became a mailserver for your own message.
[Oskar]
Signal has disappearing messages. You can choose when they self destruct. Social contract. Doesn't work for me though.
[Michael]
Privacy concerns and economic concern. There's a huge amount (cat pics) that doens't need to be perpetuated.
[Ricardo]
Introduce cryptoeconomics later.
[Michael]
Can we program in "data-destruction"?
[Oskar]
Can't guarantee it. Best-effort basis.
[Ricardo]
I think what we need are "circles of trust". Group permissions to assign data. Could have one identity for Status circle, another for family circle. Interface switching within the client.
