Earlier quoted context omitted.

That’s true for a lot of crypto but not for something like monero which has an anonymous blockchain.

Blockchains and privacy are antithetical. The whole purpose of a blockchain is to keep track of transactions so that everyone knows how many coins everyone else has in order to prevent double-spending. You can try to achieve anonymity through obscurity but this will never work in principle or in practice.

The process of reaching consensus on the current state doesn’t have to involve reaching consensus on the past state for all participants. A blockchain can be built such that all historical previous state + the txs required to get to those historical states are discarded after a quorum of nodes reach consensus on it, leaving only the current state.

(This is basically what already happens if you do a “network version upgrade” on a Cosmos-based network: everyone keeps their balances, but just in the form of a new genesis block that all the nodes from the previous generation of the network separately deterministically generated from the state, but which new nodes have to just trust. If you join the network during the new generation, you just download the new genesis, and so can’t “see back” past that point.)

Just make the whole network do an automatic “network upgrade” every block — and keep all the state in-memory in the meantime — and now you’ve got a blockchain with forward secrecy.

(To be clear: nobody’s done this yet.)

Its own currency seems odd, arguments could be made instead for better wallet integration so discreet payments could be made through signal but this would complicate ease of use for people. Also a very slim minority of people would actually perform the action of installing a wallet and connecting it to signal.

If signal is your wallet and you are sending signal coins everybody who has signal will be able to receive a payment from you without worrying about installing a wallet separately and connecting it to their account.

This is smart from a usability perspective and maybe wallet integration and other currencies will come later.

Another reason this makes sense is by controlling the cryptocurrency signal has control over the protocol to ensure it's privacy and anonymity.

Did anyone ever consider that this is actually on purpose to deter people from using Signal by it's authors?

Lets imagine, theoretically, some three letter agency in the US has forced signal to backdoor their platform somehow, and so signal stops posting source code to the clients, and everyone just keeps on using it for a year even though the authors thought that maybe this would be a big red "DANGER" signal to the users (who they're not legally allowed to inform, or shutdown the platform for any more) then how else could you try and mitigate this?

Pushing a shitcoin onto a largely tech user base may do the trick eh?

Or maybe I just put on my tinfoil hat this morning..

The piece doesn't note the additional fun fact that the website to buy the tokens is blocked in the US presumably to avoid an SEC investigation. edit: Blocked at the cloudflare level without even an explanation of why if you go there.

> fun fact It's absolutely hilarious, the SEC has gone after so many different coins, ICO's and exchanges now who have gone to far greater lengths in excluding Americans. The first person who gets around it opens you up to all sorts of civil and criminal charges. I don't understand how after years of this happening any company thinks it's somehow safe with nothing more than an IP geofence.

Thus far the SEC penalties are fairly uniformly ... raise a billion dollars from suckers, pay a penalty of $25 million as part of a settlement where they promise no further action kinda stuff. Just a really minor cost of doing business.

I'm a little surprised that nobody is mentioning that any kind of blockchain payment system creates a permanent, public ledger. One US Attorney called Bitcoin's blockchain "prosecution futures" as it's only a matter of time before the sender/receiver addresses for transactions are correlated with unique individuals. This permanent, public record of a transaction between a Signal account and another user or a service…

MobileCoin uses a combination of two other private coins, Monero and Zcash. There are no addresses on the MobileCoins's blockchain to be correlated. Didn't it cross your mind that a private messenger would probably use a private cryptocurrency?

MobileCoin does not use any Zcash technology. It is Monero + stellar consensus protocol.

Kinda funny that the post like this is written by the CTO of a company that claims to do the following:

The source is GPL3, right? Could someone fork it without the cryptocurrency code?

Last I checked, the mobile clients are GPLv3 and the desktop client and server are AGPLv3. I assume a usable fork will materialize due to Signal's introduction of a token scam. Unfortunately, signal has the network effect and asking friends and family to move again will most likely fall on deaf ears. I'll move if the new project looks sustainable.

I was recently pulled onto Signal by a non-techie who values his privacy. I talked to him about Matrix/Element and he had no idea what that was, but was very happy with Siganl. I must admit, the app is very nice. All I had to do was give it access to my contacts and bam, I am now able to chat with all my contacts. By comparison, Element is much more like a chat program than a phone messenger. It's good for "I want to…

Same here, I have been looking at Element too... Alternatively, anyone use Threema?
