    Hi guys!

    For last Techcrunch Disrupt NY a small team(including me as main developer) made messenger built on top of Nxt messaging and aliases. The idea is to hide all tech complexity about blockchain, encryption etc. The service makes NXT account for you, send you some free coins for testing purposes(it works over testnet now), encodes sender alias & title into message, encrypts outgoing messages and shows you mail-like inbox.


    Some notes(more in FAQ):
    • As it works over testnet, things could be slow(block generation in testnet is not that stable)
    • You can
    • You can send message to alias(testnet alias) only
    • No "Sent messages" as we can't decrypt them
    • We store walletphrase & alias in an encrypted form. Password is needed to decrypt. And we store no password, only its hash. So we can't help you in case of password being forgotten. Good news: we don't know usernames(aliases)  and wallet phrases as well.
    • It could be opensourced later. Time will show.
    • Bugs are possible, as it's hackathon-quality product. Please report of any found.

    I myself a new NXT core developer
https://nxtforum.org/introduce-yourself/nxt-core-java-developer-checking-in!/ . Me and my team are also thinking about building blockchain-based apps(on top of NXT of course  :)). We appreciate any help / feature requests / suggestions / friendship with developers, investors, thinkers, enthusiasts and just good people. [/list]

Wow this looks really cool. Are you planning on switching from testnet to main net at some point? If so how will that work? Will users have to purchase some NXT in order to use an account? Also, any plans to sell shares on the AE?

"Alias registered, you can now send and receive messages."

For simplicity's sake our app does 2 things: first sends testnet money(51 NXT) to account generated then register alias from that account(and waits until changes are visible via blockchain). Testnet works slow, sometimes it could be even 10-15 mins between blocks, so you have to wait :( Can't fix it, sorry :(

Guys thanx for awesome feedback! s/next/nxt will be done by frontend guys soon as well as other issues being reported.

It did! Too bad reply doesn't work, but it's still new. In any case, having something like Bitmessage that runs on NXT is awesome.

Not exactly....waiting 1 minute to receive an instant message is a bit too slow for most users.

But I think for e-mail this can work.


Also storing large image files just wouldn't be healthy for the blockchain.

Can we integrate "account management" into this identity system?

For example, some one can own an alias (his identity) and manage his accounts/wallets at the same place.

Message sending will be allowed when alias has been registered in blockchain. Wait for few minutes please. Check Profile for the current status.
It's already registered, but I keep getting the msg. In my profile the status is green.

Hi guys!

s/Next/Nxt done. Thanks for "error occured. please contact developers bytes are:" reporting, I'm going to catch and fix this error.

Thanks for nxtty link, havent' seen it before.

Wow this looks really cool. Are you planning on switching from testnet to main net at some point? If so how will that work? Will users have to purchase some NXT in order to use an account? Also, any plans to sell shares on the AE?

We are thinking about further development. There are some limitations blockchain exposed(1000 chars limit though JLP said it could be lifted up, 1 min delay). And there are some great features possible(network-wide proof-of-delivery,  transactions chained with messages etc). So we will build some product on the top of Cryptamail. At some moment we will switch to main net, probably.

IPO on AE is possible, I like the idea.

Tells me, I should to *do something* when I'm using this service at the public library.

I'm looking forward to the further development.  :)

Sorry for the newbie question here but it's difficult to understand one thing:

If e-mails are going to be stored in the blockchain and receivers will desencrypt them with their private password (how will they receive it?) can't it be hacked somehow? I mean, we need to use a very strong system that would take ages to bruteforce, so we need sth good. I'm sure there are some good algos (lots of them). But as a newbie can't see how I encrypt a message and he desencrypts it exactly. I studied computer science a few years ago and I don't remember all this stuff, could you explain it to me without going much into details, just the overview? Thanks :)

PS: Just curiosity, if for some reason you can't tell, I understand.

Encryption would be broken if curve25519 (the crypto used to send Nxt) is broken.

I doubt it's going to happen any time soon -- if at all. It  might be possible with quantum computers, but that tech  might turn out to be a pipe dream.

    Hi guys!

    For last Techcrunch Disrupt NY a small team(including me as main developer) made messenger built on top of Nxt messaging and aliases. The idea is to hide all tech complexity about blockchain, encryption etc. The service makes NXT account for you, send you some free coins for testing purposes(it works over testnet now), encodes sender alias & title into message, encrypts outgoing messages and shows you mail-like inbox.


    Some notes(more in FAQ):
    • As it works over testnet, things could be slow(block generation in testnet is not that stable)
    • You can
    • You can send message to alias(testnet alias) only
    • No "Sent messages" as we can't decrypt them
    • We store walletphrase & alias in an encrypted form. Password is needed to decrypt. And we store no password, only its hash. So we can't help you in case of password being forgotten. Good news: we don't know usernames(aliases)  and wallet phrases as well.
    • It could be opensourced later. Time will show.
    • Bugs are possible, as it's hackathon-quality product. Please report of any found.

    I myself a new NXT core developer
https://nxtforum.org/introduce-yourself/nxt-core-java-developer-checking-in!/ . Me and my team are also thinking about building blockchain-based apps(on top of NXT of course  :)). We appreciate any help / feature requests / suggestions / friendship with developers, investors, thinkers, enthusiasts and just good people. [/list]

Unfortunately it works bad now because testnet works bad :(

I'm thinking about opensourcing project, so anyone will have possibility to run own mail service against (main) blockchain & modify it according needs. Any suggestions for some features to be added before publishing?

Just to be clear.

Cryptmail is a web-client for the NXT Messaging function?
So its like SecureAE, but with messaging.

Kinda like that. Cryptamail had following unique(for beginning of May) functions:
  • Message encryption(now supported by the core also)
  • Alias-based identification, so an user could knows nothing about Nxt / blockchain.
  • Login with password instead of passphrase
  • Security: alias & passphrase are stored in encrypted-by-password form. No plain password storage also, only password hash. As a minus, credentials recovery isn't possible. No storage for messages also (as a minus,  outbox isn't possible).

Msg when a new user tries to register an alias that is already taken:
This alias is already taken. Please register another one or contact the current owner of the alias if you want to buy it.

Oh. Then we need a form that converts the entered email address and a custom msg (someone wants to buy your alias!) to an AM, which is sent from Cryptamail to the alias owner. And... then back. And… But… Hm.

 :D

Great that you will make this open source. It needs to live.  :)

The plan for now is to opensource it (after 1.4.0 probably)

Is this still being developed? The idea is awesome, will it be released on mainnet at some point?

The project has been abandoned and will be opensourced after 1.5 mainnet release with Prunable Messages usage instead of ordinary ones :)
