This messaging feature rumor about cinni sounds interesting. I used the BItmessage protocol for some time just for fun, which I think is a similar concept but with PoW.
A PoS distributed messaging system could indeed be interesting and I hope rat4 is considering something like that.
Anonymous chat using addresses seems like a very easy implementation to be honest...
That's so cool though ! Would be sweet if someone put a game on the wallet too? like flappy-... oh wait...
/sarcasm
I'm not a big fan of gimmicks. There are thousands of chatting programs already that do it better. Why fill up the QT code with extra bells and whistles?
I totally agree but this is really not a gimmick but a service that operates the existing ledger and PoS system of BlackCoin. To the best of my knowledge there is no distributed messaging service (i.e. without central server like facebook or google) that works on a PoS basis.
Still it's use is certainly not for normal chatting. I could understand it with messaging an actual deed to each other, but I guess there would be better systems for this.
Blockchain messaging is actually a very interesting topic. It can replace things like public notaries, and be used as a means to permanently keep records forever on the blockchain. It's a purely decentralized communication platform, that can't be shut down by a government. Some other novel uses I've heard is turning it in to an API to play games over the Blockchain (imagine a game of chess using the Blockchain.) But also would enable us to create really complicated API systems to create transactions we've never thought were possible before. The message doesn't have to be big only about 512bytes, that's more than enough.
Remember guys, speaking purely from a technical aspect, the Blockchain is the most important part of any coin, anything we do to reinforce or extend the functionality of the blockchain is a direct net benefit to the coin. That being said, I don't know what rat4 has on his schedule, and if he sees Blockchain messaging as something important.
Yes, the blockchain is the heart of all things but almost every change (except for optional extensions) leads to a hard fork ...
What I mean is that we actually can "abuse" the PoS system itself from BlackCoin to develop a distributed messaging system that requires no change of the blockchain at all:
- Lets say A wants to send a message to B using of size N. Both A and B know the private key of B's address.
- In order to establish trust to the network, A generates a PoS block of the BC blockchain that stakes at least P(N) coins with P being a suitable cost function of the message size
- A propagates the signed message encrypted with B's priv key together with the (unencrypted) signed PoS block to the messaging network
- Every client in the network that receives a messages checks if the block stakes at least P(N) coins and propagates or denies the message accordingly
- B has to be online as long as A's coins are on stake to receive the message over the p2p network
This is only ONE very simple idea to take advantage of PoS as trust establishing system.
