Nxt 1.7.4 update: new features and a hard fork (!) at block 621,000

http://jnxt.org/countdown/?block=621000


(click for the real countdown timer)

The current Nxt client software NRS (Nxt Reference Software) 1.7.4 was released at the start of this month.
It contains a number of new features and changes that will be activated once Nxt reaches block 621,000, in about 10.5 days time.
This release is the culmination of a lot of work over the last few months, and will no longer be compatible with older releases (ie anything from NRS 1.6.x and below).

For ordinary end-users this update will not be a big issue, simply ensure that you have updated your server/node software to the latest 1.7.4 version:
https://nxtforum.org/nrs-releases/nrs-v1-7-4/
preferably before the hardfork block. People running older versions of the NRS after the hard fork block passes will find themselves on an invalid chain, and will be ignored by the majority 1.7.4 network.
See here for realtime details of the Nxt network:

As you can see, of the current 263 Nxt nodes online, 161 are running NRS 1.7.4, a substantial majority.

For people who are running an Nxt-based project (or a system that uses the Nxt API, like exchanges), the situation is slightly more complex as there have been API changes made in the step from NRS 1.5.15 to NRS 1.6.2. This means that if you have already successfully upgraded to 1.6.2/3, the upgrade to 1.7.4 will be simple as there are no substantial API changes to consider.
However, people who need to update from 1.5.15 will probably need to make code changes to accomodate these API changes.

All of the info on these API changes, and on the new features that will be implemented can be found here:

https://nxtforum.org/nrs-releases/nrs-v1-6-2/

https://nxtforum.org/nrs-releases/nrs-v1-7-4/

We've already posted this information on multiple fora/social media, and directly mailed it to most Nxt-based projects/exchanges with the NRS 1.6.3 release, but it can't do any harm to remind everyone.
As ever, if you have any questions, post here, ask on the Nxt forum, or give our recently created helpdesk a try:

Thanks for the help with Shuffling Sunday, people. We, again, got lots of testing done, but so far no nasty exploits found.(Sadly)
If anyone wants to seriously have a go at breaking the Nxt CoinShuffle feature, and earning some nice bounties in the process, we may run another Shuffling Sunday (the third so far) on the 17th Jan, just before the 1.7.4 hardfork at block 621,000.

Which brings me to:

Time for a swift kick......if anyone feels like testing (and preferably breaking) the Nxt CoinShuffle feature, come on down !

Shuffling Sunday II: Sabotage !

https://nxtforum.org/news-and-announcements/shuffling-sunday-!-%28testing-nrs-1-7-2e-coinshuffle-13-12-2015-%29/

There is a bounty pool of at least 50,000 NXT available to participatiing testers, and we'll be running Shuffling Sunday testing both today and next week, 17 Jan.



Happy New Year to all the BitcoinTalk crew, btw !
(yeah, I know i'm a bit slow)

Who can break an Nxt Coin Shuffling? We will be holding Shuffling Sundays on testnet again, but this time the goal is to find a way to break a shuffling and get away with it! Now that the source code is released, everyone is invited to dig in, find an exploitable loophole, and get a bounty.

ok gonna buy some later for now i m focused on dmd & hbn

Support us too please in official CORE/CORE Media thread https://bitcointalksearch.org/topic/core-core-media-httpsbitcointalkorgindexphptopic-20123830-1064803

You can install it back and install no-script plugin, that way it blocks flash on pages you dont want to, and enable it when you desire.

Argh, it needs Adobe Flashplayer to be viewable. I deinstalled this plugin since of security reasons.
The creators of this magazine should really switch to HTML5 or other open technologies.

Leasing your balance to a forging pool can be profitable if you lease a big enough balance.

You can learn a lot at the nxt wiki.

I pm'ed him and he said yes.

you need a substantially greater amount of NXT to forge successfully. you COULD forge a block, but it's very unlikely. the algo details are somewhere on the nxtforum if you're curious

Well, 2700 is a very small stake. It will forge something, maybe once or twice a year.

Check out the calculator... https://www.mynxt.info/forging_calculator.php

hello
so i have 2700 nxt sins 2 month now
forging is enable   but  forging balance = 0     so how long to get reward ?

where can we see details about forging because i can't find that

Is he actually selling it?

Change log:

This is the first stable release in the 1.7 series. It is a mandatory update
for everyone. There is a hard fork scheduled for block 621000, estimated to
occur around Jan 21, 2016, at which new features will be enabled. Nodes that
do not update to 1.7.4 or later by this date will be left on a fork.

On testnet, the hard fork block is already passed, and all new features are
fully functional.

There were incompatible API changes introduced in the 1.6 series. API users
still on 1.5.15 and earlier should make sure to read the 1.6 series changelogs
and forum announcements, before upgrading to 1.7. These changes do not affect
regular end users who just run the NRS client on their desktop or VPS node.

The new features and improvements in the 1.7 series have been documented in
the 1.7.0e through 1.7.3e changelogs, available in the changelogs directory.


Here is a high level summary of the new features to be enabled after the
hard fork:

Coin Shuffling, a fully decentralized coin mixing, to improve account privacy.

Account Control for phased transactions, the Nxt equivalent of multisignature.

Immediate release of certain types of phased transactions on approval.

Improved block times, 60 s average, long block times now extremely unlikely.

Account Properties, assigning arbitrary name/value metadata to user accounts.

Singleton Assets, useful for representing single tradeable objects.

Dynamic fees, proportional to the relative transaction size.

Improved Exchange Booth UI.

Data Cloud, adding a UI and multiple enhancements to the existing Tagged Data
feature, to allow decentralized, censorship-free and tamper-proof publication
and retrieval of small files, documents, or arbitrary data. This feature is
not dependent on the hard fork and will be fully usable immediately on update
to this release.


Changes added since the 1.7.3e release:

Added detectMimeType utility API, allowing auto-detection of the mime type of
uploaded file or data, using the Apache Tika library.

The uploadTaggedData API now uses such mime type auto-detection to determine
the mime type of uploaded data when the user has not explicitly provided a
type parameter. It also automatically sets the isText property to true for
data of type text/plain only.

Made the maximum permitted number of forgers or shufflers running at the same
time configurable, default 100 each, using the nxt.maxNumberOfForgers and
nxt.maxNumberOfShufflers properties.

The default value of includeCounts parameter in the searchDGSGoods API is now
also false, this API was inadvertently missed when globally changing the
defaults to false in the 1.6 branch.

Various UI improvements.

Updated Bouncy Castle library to version 1.54.

I think this is wishful thinking. But, it can't hurt.

Depends where you live in, many countries havent decided on cryptocurrencies yet.


Because it wasnt advertised hard enough. We can advertise it very hard and it will bring a huge adoption to NXT.
