-----------------------

Finally I got around to implementing a protocol I've had in mind for a long time.
The idea is extremely simple but at the same time extremely powerful.

With the gossip protocol everyone running a FIMK server can send a message to one or more of his connected peers and be pretty sure that same message is distributed as fast as possible among all other peers.

Nothing is stored however!
All that remains on any of the servers is the ID of the message. And only for a limited amount of time just to make sure we don't keep sending the same message around.

To actually do something with gossip messages the receiving party should be actively listening for them.

A party does not need to listen for all gossip messages!

What you do is create a special key which is built up from a sender, recipient and or topic (or any combination of that) and you'll subscribe to that key through two-way websocket client/server connections.

Now when anyone sends a gossip that matches that key, as soon as that message reaches the (p2p) server your client is connected to you will be notified.

Having a free distributed messaging protocol could potentially come at a cost.
That's why all transactions and blocks on the network always go first.

It is a very early stage and these extra measures have not been enabled yet but this protocol comes with excellent spam prevention methods.
Since every gossip message has a sender and every peer in the network has knowledge of that sender's balance we could easily require a sender to have a minimum balance, we could also limit the number of messages per minute/hour/day etc per account ..

Every gossip message is signed with a secret phrase which proves who send the message (same mechanism as signing blocks).
Every gossip message is timestamped and the timestamp is included in the signature, messages older than - or from more than 15 seconds in the future are discarded.

The live chat feature is just one of it's uses and is what is available in lompsa (used to be mofowallet) 0.4.7 now.

Lompsa 0.4.7 shows how with this relatively simple protocol we can create a sophisticated client side (javascript) distributed real-time communications platform.

# client side protocol implementation
https://github.com/fimkrypto/mofowallet/blob/master/app/scripts/services/gossip-service.js

# messages are stored and served from indexeddb
https://github.com/fimkrypto/mofowallet/blob/master/app/scripts/providers/gossip-chat-messages-provider.js
https://github.com/fimkrypto/mofowallet/blob/master/app/scripts/providers/gossip-chat-list-provider.js

Lots of other uses exist. Free fast real-time communications between FIMK users is just one of them.
Eventually the protocol could be used for anything.. communications, games, live multi-sig, live trading etc..

Experimenting with new p2p distributed real-time gossip protocol.

sorry for late reply. that part is not automatically updated i know, it's on the list 
just navigate to another page and click back button and it will update.

I'm sorry. Totally forgot to update here.
There has been an intermediate release for a few days now which is here https://github.com/fimkrypto/mofowallet/releases/tag/v0.4.6 i'm sorry it's not final but the new (now really) free chat feature (called the gossip protocol btw..) is taking up a lot of time.

Problem turned out to be an angular issue where text input was automatically trimmed (spaces removed at end and start) before it updates the model.
Fix is here: https://github.com/fimkrypto/mofowallet/commit/6458f50fa79857b11be2de55013d0ca1d8c1de0d
Will upload new build when i have a chance.

Thanks PilotBTC! (unfortunately i don't really see a work around atm)

You are correct.
The space at the end is eaten somehow.
I'll fix it right now.

Thank you for pointing this out.

sure it's the same? not perhaps a missing space at the start or end?
what happens if you only login in for the session..

Sign in / Enter pass phrase / FIMK / [enter the passphrase] / Save to wallet? answer NO / Continue..

Did you start the FIMK server?

After you sign in you can start forging (Click Account / Start Forging).
There should be an indicator that you are forging and when to expect the next block.

Or use online of course. Best viewed in chrome or firefox on your desktop or mobile device..

Forging on mofowallet.com is not possible.
For alias transfer go to your account page look up the aliases page click the transfer button next to the alias.

Q: What good is a an encrypted mobile chat app without emoji support?
A: Not much 

Thats why we support the full-set. Either type the colon format code (if you know it), use smiley faces etc.
Or select one from the menu (as shown below).



Now combine our on-blockchain encrypted messaging with our free encrypted/anonymous transient messaging and I believe we a have a winner.
Better start dumping those WhatsApp stocks 

Some more info on the topic:
http://fimkchat.com/2015/07/enabling-virtual-exchange-on-nxt/

We are preparing the upcoming release, part of this release is NXT-PLUS based on 1.5.12 and with the virtual exchange enabled.
Assets can be found by typing part of the name or description in the filter box.



Try it out here:
https://www.mofowallet.com/launch.html#/activity/nxt/assets/latest

The new UI is (at the moment) only available on hosted mofowallet, expect some downtime from time to time while we upload new versions.



Try it out here:
https://www.mofowallet.com/launch.html#/assets/nxt/12071612744977229797/trade

Theme switcher still available under settings menu, current default theme is named "Google", if you used hosted mofowallet before you will still have "Yeti" theme selected. This theme is named "Slate", total of 19 themes available.



The upcoming Private Assets feature (FIMK only) and the new Email Account Identifiers (FIMK only) are available in the java server code but have not been turned on yet. For this a hard fork is required which will likely be happening in the coming weeks.

The URL's involved are not of the sort you could actually type, they are too long for typing as you can see in the example URL.

Example url (does not work since hosted mofowallet does not run the development version): https://www.mofowallet.com/launch.html#/login/7b0a2020226374223a2022677051734f6b6d506364634b69704c682f34366268644e39624839307970646c6d30766349324c456e334854454b7435766a3074306f2f67726b7367555061666647546e4e52544e31506a726a6f54722b2b416e69483363367a797253396950794a3449526b396b2b71714a4e316c6e54494549416b32453946664f34656f353942762f7a7476783639342b556471436e77302b61413d3d222c0a2020226976223a20226334626462343265366565366261613366393336333061616531353262343735222c0a20202273223a202235346265303034653634363038393132220a7d

You are right that typing it wrong could potentially send the whole thing to a search engine (encrypted) but what is the chance of that happening when clicking the link or pasting it in the url bar?
Copy pasting your secret phrase could in a way also be potentially dangerous, if the key is still on your clipboard and you press paste (CTRL-V) in either the url bar or the search bar it is also send to the search engine but now it's unencrypted, this is how things are done now in both FIMK and NXT.

The wallet part in the URL is not send to the mofowallet.com domain. All the mofowallet.com server will see in it's request logs is everything up to the # sign in the URL. This is how all browsers (or better yet the HTTP protocol) works, everything after the # sign stays only client side.

When you land on hosted mofowallet users are asked to unlock the wallet and are then presented with ways to store the (encrypted) key in the browser local storage or to download a file backup. This method is especially easy when using a mobile/small device where all you need to do is click a link you emailed yourself to transfer your keys to your mobile.

Users are asked to unlock their wallet.


Users are asked to name the account and to make a backup.

There is a #FIMK channel on the supernet slack for anyone interested.

Go here to get an invite http://slackinvite.supernet.org/

Nothing is ever send to the server your key remains client side. Many other crypto projects are doing the same thing.
Plus there is basically no difference between either having an encrypted file with your passphrase in it or having a URL with the encrypted passphrase, the latter is just easier to work with.
Of course if you need top security for critical accounts the whole brain wallet mechanism remains fully intact, the new developments are more geared to lowering the barrier for when we start developing UI and apps for the average Joe kinda user.


There is zero risk involved here, all it is basically trying to do is bring the dynamism as is known in the P2P network (which goes beyond the reality we see each time a block is forged) directly to the client.
So in a way the client 1-on-1 reflects whatever is happening on the network.
For this to be possible websocket support had to be added first, which we did a while back the virtual layer now completes it (although it has to be tuned more).


Asset to asset (as opposed to asset to fimk) trading is what we have been preparing for.

Hi James, nice to see you here! 


I agree.

Progress has been picking up since the start, we're getting more comfortable with the platform every day.
But I agree that it might not have been showing that much, as was said before FIMK is not about pumping we have a long term vision and for that to become a reality a lot of 'boring' low level work has to be done first.
Some of that work would not have been possible before since a new platform has to be mastered first.

-------

One more thing about the new account identifiers. It might have appeared as if everything has to go through our centralized (delegated would be a better word) verification process.
That is not the case, everyone can assign their own name@fimk.fi address. It is also possible to assign a @fimk.fi address to an account you don't own but for that you have to provide a digital signature signed by the owner of the account you are assigning the id to.
All this functionality will be easily available from all the various clients.

The name@fimk.fi addresses will also be fully functional email addresses to which you can send an email. Hosting for those addresses will be provided by the Krypto Fin ry association free of charge and will allow for a whole new set of possibilities (send FIMK to email, get blockchain notifications, fully encrypted emails and 2FA are only but a few).
