NXT :: descendant of Bitcoin - Updated Information

How are aliases verified?

Say I want to send to an account alias (presuming this is implemented in the future), if a rogue node tells me that nxt:name links to acct:000000001 (attacker account) instead of acct:3209075099254042753 then I could loose my money by sending it. How is this prevented?

Is it possible to get a list of active peers and other stats from the client via http://localhost:7874/nxt?

Interested to see if I can script something to check on the client externally, e.g. restart if certain conditions are met

thanks,

Ian

Check http://localhost:7874/nxt?requestType=getState and http://localhost:7874/nxt?requestType=getPeers.

U should trust only to hallmarked nodes that signed their response. If one of them sent u incorrect data u can prove that and stakeholders can vote on destroying all the stake of the rogue node. Also u can ask 2-3 nodes before sending big amounts.

Edit: BCNext said that pay-to-alias would be implemented later.

NXT Assets currently are issued with all of them created at once. Kind of in the spirit of NXT. However, for creating a 1:1 correspondence between the NXT AE Asset and something tangible, this issue all at once model is not quite right.

For example, in the gateway I have to exchange deposited DOGE with NXT AE DOGE. Since there are 100 billion DOGE and only 1 billion NXT AE DOGE possible, that would create a problem if more than 1% of all DOGE is deposited. For a NXTcoins that are mined at a rate of 100,000 per day it is quite important that the number of NXT assets in circulation match the number that was mined.

In order to make it easy for people to deal with these type of cases, I am creating a NXTcoins development kit where you will be able to specify (within reason) the properties of the coin, especially as it pertains to total authorized, total in circulation, creation criteria, etc.

Question from a new nxt/btc exchange (nxtchg.com) founder: "Guys, what's the best way to check a NXT address for incoming transactions without installing the client? Block explorer? Is there an API for this sort of thing? It's needed for automated NXT deposits.".

An exchange must host its own client. Any other way is insecure (at least now, when hallmark protection is not used for everything).

There are more than 40 active peers listed, communication seems good.

Set "communicationLoggingMask" to "3", "pullThreshold" to "1" and "readTimeout"/"connectTimeout" to higher values. The log will show what is wrong.

NEWS

On the 3rd of January the source code of basic features will be published for peer review. BCNext decided to make it more interesting to do a review, so the code will contain 3 security flaws - serious, critical and fatal ones. The 1st person who reports one of these flaws in a special thread will get a reward (1'000, 10'000 and 100'000 NXT accordingly). There will be SHA256 hashes of flaw descriptions published, the descriptions will be revealed after the flaws r reported. If some unreported ones left after 3 months, BCNext may decide to reveal them at any time.

PS: This has a nice side-effect, copycats have to wait for full disclosure or do their own research.

Is this still the plan? I mean the flaws.

So tiring to code.... The one I am working on is without hot wallet and seek consensus over multiple self hosted highly hallmarked  nodes.

I see that the blockchain explorer server is down for 24h.
Does this mean that there will be no transactions between DGEX and our wallets for the next 24h?
Thanks

blockchain explorer is just a website with stats

No.  The two sites are completely unrelated and do not depend on each other.

The account secret Phrase is dangerous! Even setting more than 60 characters and contains special symbols.

Imagine, when the future of NXT popular, maybe just one random password combination can open an random account.

There are lot of logs like this:

does this mean my blockchain file corrupted? I always restart nxt by Ctrl+C

Try traverse password dictionary, login, maybe can successfully enter some people's account..
