Nxt General Discussion / Re: Is it possible to change NXT passphrase ?
« on: December 29, 2015, 03:39:01 pm »
I guess cryptocoins using public ledger tech like blockchains can't have offline wallets according to your definition of what an offline wallet is.
.....message truncate......
So I would argue that no other crypto has a wallet as offline as nxt thanks to jones and vapor wallet...

I think by offline wallets he meant cold storage; an amount of crypto coins contained in a place disconnected from the blockchain.
NXT doesn't have such storage.

NXT doesn't really have an offline wallet. Once created, account data is stored in the blockchain and the account is accessible from virtually any wallet anywhere. I'd say there are local wallets and hosted ones. Local wallets run on personal computers while hosted wallets are in the cloud. e.g. wallet.mynxt.info

The closest thing to an offline wallet is a Jay's Vapor Wallet: jnxt.org/vapor
Not sure whether it is up-to-date or is still maintained by the author.

Below are the pros and cons I can think of between using a hosted wallet and local wallet listed in no particular order.

Hosted wallet
Pros
1. Instant access. No wait-time for blockchain download/sync.
2. Accessibility. Accessible from practically anywhere.
3. Some online wallets offer other type of authentication than just a long string of password. e.g. pin-based password, username-password pair, 2-factor auth, etc. It is likely that an account created by these services won't be accessible from any other wallets as they have their own database to store pin-password pairs.
4. User Experience. Some wallets have simple features and straightforward user interface.

Cons
1. Security and trust issue. It is difficult to verify the security and the integrity of the hosted wallet (or the host, for that matter).
2. Dependency of service. When the service is unavailable, it may lock users out from accessing their accounts. (See point 3 of local wallet's pro's)
3. Centralised. One host, one NXT server, may service multiple users and thus it promotes centralisation.

Local wallet (or default NRS client)
Pros
1. The integrity and authenticity of the software is verifiable via hashes.
2. Promotes decentralisation and contributes power to the NXT ecosystem by means of forging.
3. Users have more control over the environment it is run on. This may also be a disadvantage if user's environment are compromised.
4. Customisation. Users have total control over the wallet; which version is installed, which plugins to use, integration with other services, etc.

Cons
1. Complicated. For some cases, it may be a bit difficult to get started due to user's lack of technical computer skill/experience, software incompatibility, etc.
2. Vulnerabile. User's personal computer may be hostile or infected which may result in account theft. But this point applies to hosted wallets as well.
3. Too many features. The default NXT client has more than just a wallet which may not relevant to the average users. It has a messaging system, assets exchange, digital good marketplace, monetary system, voting, and more. Hence it is called a client.
4. Operating costs are on the users. Rising blockchain size, CPU and memory resource, internet bandwidth, electricity, etc.

I am sure there are many other points I did not mention for both types of wallet. It is all situational, but there you have it. I hope you get a bit of an idea which one is more suitable for you. :)

I am curious again about the licensing they use. Is Mijin MIT, GPL, or is it not open source? If open source with permissive licensing, how are they going to deal with clones, and how will they make money from potential customers who don't feel like paying for support but just use it under that open source license? Or is the idea that even though you give away Mijin to be used for private blockchains for free, some of that use will eventually trickle down to the main NEM blockchain and result in increase of XEM value?

The Mijin website states that Mijin will be open-source but dual licensing.  I don't really know what that means.  http://mijin.io/en/about-mijin

I'm seeking feedback from you JL.  If a big exchange hired you to build a private fork of NXT, what kind of licensing would you use or want for that fork?  (I'm very curious and its an honest question as I have always respected your role and work in NXT and I know you have thought a lot about licenses recently.)
Something similar to this actually has happened in the past. Consequently, JL updated the licensing for NXT. More information on this should be available on this forum if you look up for 'NXT license'.

I'll get back to you when I found the URL.

300 NXT

Goodluck with the book.

NEM devs admitted they've had to abandon developing NEM for a few months to work on Mijin, a private fork of NEM. A conflict of interests?
I thought Mijin was part of NEM. :-/

NXTventures / Re: SkyNET 6854596569382794790 - decentralized AI
« on: December 22, 2015, 08:41:37 am »
Is this the same OpenAI initiative Elon Musk (among others) plans to pour billions of dollars upon?

While I am personally excited and entertained by the idea, I also have my concerns as to what this mean for us and how it will affect the life of our (digital) society in the short and long run.

Quote from Harvard Business Review:
"One of the aims of OpenAI is to share their work with the world (for example, they have committing to sharing any patents they might develop). A noble goal. But from there, who do you think is going to be best able to exploit whatever is developed? I wouldn’t claim to be an expert in the field of AI, but I’d hazard a guess that it’s going to be those with the most computational resources and, increasingly, proprietary data to dedicate to it."

Every now and then, there are some amazing people coming to the NXT community with their ways of thinking that I really cannot understand.

« on: November 30, 2015, 05:01:23 pm »
I agree with (almost) extinct animals name as NRS version name to also raise awareness to destruction of habitats in favor of fulfilling ever increasing demands in energy consumption.

But on the other hand, NXT could be associated with these extinct animals as one of the many extinct technology. That would not be funny. Or maybe it would. :-\

Introduce Yourself / Re: Hello NXT!
« on: September 10, 2015, 03:18:57 pm »
Welcome. I hope the wallet you are using right now has a much more secure passphrase (and not just a couple of characters more) :)

Looking forward to read about NXT on your blog.

There is no chance an unpublished bitcoin address could have been bruteforced. Somehow somewhere it must have been 'published' or 'sneak peeked' by a trojan.
a bitcoin address plus salt would be easily cracked unless the salt has high entropy

How? A bitcoin address is 33 characters, lowercase/uppercase letters and numbers. This is enough entropy.
If it is indeed a published bitcoin address, I would count it as 1 entropy.

since the account was already comprised. what was the passphrase your friend used?

it doesnt matter now since its compromised.

by showing us your passhrase, it will help everyone in the future to not use something like yours and also give us a glimpse of what kinds of passphrases hackers are targeting.

my suggestion for the future when creating a passphrase is to do a "drag and drop method" when getting your passphrase from another window. reason why is that loggers usually only monitor your clipboard data. as for password strength, consider making your own ceasar cipher which includes punctuations.
I would strongly suggest not to share any passphrase in public for whatever reason.

Besides, the OP has already told us that the passphrase was a (unpublished) bitcoin address + salt. That should already give us an indication of how strong it is.

....
Perhaps some guy is data mining various passphrases using common things such as BTC addresses?

I would imagine there are a few people doing this.
....
Yes. I guess it is safe to say that there are some people who are running brute force attack bot(s) to open NXT wallets using a table of public data such as dictionaries, lyrics, popular quotes, poems, holy books' verses, etc. Imagination is the limit. And then just run a check on each wallet for positive balance.

I won't be surprised if this is run using nowadays personal computers.

Im not sure how, but i expect his passphrase was cracked, and it was a long passphrase.
I dont think he had a huge amount of NXT in the account, but he has traced it through the block explorer going through 4 different accounts and then finally ending up in NXT-253H-ESRL-K87C-4R9FG.

Googling this account appears to be linked to a scammer, but it contains around 2.7M NXT.


Any ideas on whats gone on?

TIA
Check if that account belongs to an exchange. If it is, you (or your friend) probably still have a little hope. Try to inform this incident to the exchange and they probably would cooperate and try to find a way to return the NXT to your friend.


Out of curiosity, just how long is your friend's passphrase and does it consist of a variety of characters (capitals, numbers, symbols, special characters, etc)?

Have you checked which versions of NRS these nodes are using? They could be on a fork/separate chain.

I have just had a dream last night about NXT. And in that dream, NXT was adopted by a very large bank (I won't say which). Right after I read the news, I headed to CMC to find NXT still on 8th position even though the volume was exploding. But I remember feeling so happy; that it was the beginning of a worldwide use of NXT.

A brief and yet pleasant dream to have. And so I thought it would be nice to share it with you guys. :)

NXT doesn't need any bank to adopt it to succeed.  The original intent of crypto was to allow people to be their own bank.
Yes I am aware of that. Adoption by the banks would defeat the purpose. Would it make more sense if it was a very large commercial entity, instead? ;)
