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.

Normal use of the term "offline wallet" is the same as "cold storage".

Nxt has it like any other crypto. Creating your address on a computer that isn't connected to the Internet is usually what is meant by the term cold storage.

What are the main steps to make a NXT account secure using windows?

Windows creates the first account with administrator rights. I would recommend creating a new account that doesn't have administrator rights, and only using that.

Like with any other crypto, to be totally secure you would need two computers, one offline and one online.

I personally woundn't recommend anything like this. The passphrase created by the client is secure. If you don't trust it (I haven't heard of any reason not to), you can add your own extra words to it.

We should drop objective facts about NXT initial and actual distribution here and there in our marketing campaign.

Is it worth it? Nothing has been discussed more than the distribution. Also I think anonymity or pseudoanonymity is one of the most important features of cryptos. Being able to know or estimate who owns how much goes against that idea.

Let's talk about it in a professional marketing way now, since we have the right people and the funds.


I'll restate that I think it's a bad idea. Saying anything about the distribution highlights one of the problems with currect blockhain technology. Also Coin shuffling will provide a partial fix to that problem. Note that the traditional banking system doesn't publish everybody's account balances.

Somebody asks: I heard that the distribution is bad, is that true?
Answer: We don't know anymore, because we have Coin shuffling. I you wish, I can provide you some historical information. I also don't know how many dollars my bank has in each account. That's the way money works.

Core Development Announcements / Re: Start preparing for 1.7 - NOW!

Will there be a point in the not so distant future when the NXT devs will implement a stable API?

I'm not a dev, so these are only my opinions.

I would imagine changes will be made if something is discovered to work incorrectly. My reading of the changes in 1.6 and 1.7 was that the devs felt Nxt worked incorrectly. Were they absolutely necessary is another issue.

I would also imagine that if there is an application worth 500 million dollars which uses an API that is considered to work incorrectly, the API would not be changed. At that point Nxt would have found its use case. But to get to that point we need active devs. I don't think tieing their hands by requiring that the API is kept perfectly stable is the way to get there.

I can certainly see a big problem with the change, when the amount of operators using NXT is large, and also broad like the Linux example.

Linux and operating systems are old tech.  It's not a great comparison to cryptos. Nxt was supposed to find other use cases for a consensus network in addition to money. I don't expect the APIs to be perfect immediately.

Also there hasn't been continuous change in Nxt's API. There was a fight because a small change was made.

Change is a good thing. It shows progress.

It's great that we have active devs, and a roadmap with more features. I didn't see the need for a API change in 1.6, but I don't want to see a stagnant platform either.

If at some point the majority of Nxt users refuse to install the new version from the devs, the platform will be frozen. I hope most of the features in the Nxt roadmap will be implemented before that. Unfortunately the Nxt devs seem to have wasted some "capital" for change in 1.6.

- How it was solved
 - What will be / has been done to prevent it from happening again, what we learned

I see it in terms of risk/reward. Changing the API may cause somebody's software to break. Is the reward (new features) worth it?

Here is an old API issue that has not been fully resolved by all users:

https://nxtforum.org/nxt-helpdesk/how-can-i-remove-the-nxt-change-by-bitcoin-in-bittrex/

Bittrex makes it difficult to fund accounts for new users, but public key announcement was an important feature at the time.

You can use http://jnxt.org/key/ to initialize your NXT account. Then you can send NXT from Bittrex.

Jean-Luc: the time spent discussing the "incompatible" changes in 1.6.2 already exceeds the time it would have taken to fix supernet and go on

From what I understood the change could have been done by either party in 1 hour, so it's annoying to see a lot of value destroyed because of a trivial point.

Couldn't the forum link at least be kept to 1.5? There might be other API users who get annoyed enough to stop using Nxt. Even if they would do it later anyway, but this would maximize the time the official version has a stable API.

To me it is clear that if this version breaks the API, you should revert it.

In the current environment Nxt is in, a change in the API could make many services permanently broken, and many of them will not be updated. Maybe some software companies can force their clients to upgrade, but not Nxt in the current situation with the falling market price.  Services that use Nxt and notice it has stopped working would just disable it.

As part of the overall Tennessee plan, we want to put some serious pressure on the development of lite/customisable clients and webwallets.
Good GUI devs need to be paid, secure webwallets are also not cheap, so putting funds towards either would help.
You don't have to subscribe to Tennessee, but maybe offer your funds as a bounty for a specific project.

BTW, could you also pay somebody $20 a month to run the standard Nxt wallet at port 80 on a memorable domain name. Maybe even some ads with a short message, something like "NXT cryptocurrency - try it at  memorable.domain.com".

NXT is not secure, we don't argue or try to disprove said statement, so third parties must believe it's true, and as a result don't invest in NXT, because investing in NXT means you will probably lose all your money in some network attack...

Maybe it can't be disproved at the moment. POW can be 51% attacked. Any cryptocurrency can be attacked if there is a bug in the code. Even if POW is more secure, POS might have a good tradeoff between security and efficiency. It would be nice to know what is the probability of a practical attack for each of the competing cryptocurrencies and implementations, but that question is clearly unknowable at the moment. Would a POW proponent admit that POW can be attacked? Maybe they will say it is a theoretical attack, but somehow a N@S attack is practical.

:o :o >:(

The problem is word NXT ?

No. It's the lack of independent sources, links etc. (I wonder if the deleter even read them all. There are many on the Nxt page).

So I repeat, please find specific issues with my protocol:

1. Alice sends txid of funding tx to Bob
2. Bob signs a 2of2 multisig transaction timelocked into the future refunding Alice
3. Alice signs and broadcasts the funding tx into the blockchain after verifying refund tx is proper

The funding transaction goes through Bob's node, Bob changes its txid and disappears, refund tx becomes invalid, and Alice loses her money. Bob can later try to extort Alice to sign a transaction to return half to Bob and half to Alice.

It's probably not a problem at the moment, but if a service that is vulnerable to a malleability attack becomes more popular, attackers might appear. Mt. Gox initially blamed their losses on malleability (true or not).

Alice creates funding tx and doesnt broadcast this until she is satisfied that the refund tx (and phased tx) are all valid.

Bob changes the funding txid (even if it is not Bob's transaction). This can happen even after the transaction has been broadcast, but not included in a block. This problem doesn't make this kind of scheme unusable, but a little risky, similar to accepting a 0 confirmation payment.

I only watched a Youtube video about this some time ago, so I don't have all the technical details. There might even be a fix to this later this year.
Please tell me how Bob can change the funding txid?

If he has a node, and the transaction goes through that node and gets included in a block.

"Thus, while uncommon, it is possible for a node on the network to change a transaction you send in such a way that the hash is invalidated."

So if Alice is trying to cheat by making the funding tx invalid

The known problem is the refund transaction being invalid, not the funding transaction. Bob quits, and Alice has no valid refund transaction.  (I didn't read your protocol carefully, but there is a fundamental problem with a refund transaction, at least at the moment.)

4. Alice verifies the refund is proper and if it is, broadcasts the funding transaction, which creates a spendable output

Bitcoin refund transactions have a known problem. A refund transaction works only for a specific txid, but the funding txid included in a block can be something else (malleability), which would cause the refund transaction to become useless. Do you have a solution for this?

If you are a programmer, google "bitcoin api" and "nxt api" and compare.

If you are a startup with an original idea, you would save yourself a lot of time by implementing it in Nxt instead of Bitcoin.
