I still think NXT needs more marketing

There is nothing stopping the completed, open source NxtAT project being implemented in Nxt in the future once the turing complete concept has been proven safe in the wild.

Marketing ......etc

More marketing won't speed the implementation of NxtAT, it is perceived safety of it that is the issue.

You know I tried NXT for one of our colored coins and it was a little confusing.  Plus the number of confirmations that it wants can take a long time on a network with that few nodes.  I appreciate the effort but will wait a bit for it to get a little higher popularity.

Ok, there are  alot of people how can clear up any confusion. Were you trying to use the asset exchange or monetary system for your coloured coins?

I don't follow the bit about number of confirmations. What were you trying to do? You only have to wait 1440 blocks if you want to forge. You can spend/move your tokens after 1 block and these come around every ~80secs on average (in NRS 1.7 this will be 60 sec). I don't see how the number of nodes effects this.

A little more detail on your post would help.

Does nobody use jNxt anymore? Or mynxt.info?

Suggestions on how to make these more simpler would be welcome.

I thought we had been through the pros and cons of Turing completeness in early 2014!  Grin To repeat ourselves for anyone who wasn't around almost 2 years ago (and is actually interested in facts and not rhetoric  Cheesy )


Here is my version of this post from Nxtforum, March 2014:

Paraphrasing CIYAM on Nxt vs Ethereum (from memory):

"Ethereum will use scripting for all transactions, Nxt will just use it for select, more complex ones.

Think of Ethereum as a motorhome and Nxt as a sports car. The motorhome can do everything you want when on the road with a lot of in built features but it comes at a cost of slow and cumbersome for just popping out to the shops and ordinary, day-to-day things.

Nxt being a sports car is fast and agile for day-to-day activities but you would struggle to go camping with it. Enter AT which would be the trailer that you hitch to your sports car just when you need to go camping. Towing will slow you down but you are only towing when you absolutely need to, unlike the motorhome where you have no choice but to 'tow' all the time."



ordinary, day-to-day things == simple transactions, send/receive
camping/built in features == turing complete
towing == scripting

I think that was it  Grin


CIYAM is the lead dev of the Automated Transactions project. This is known as NxtAT within Nxt and is a completed open source turing-complete bolt on for the Nxt ecosystem (the caravan for its sports car  Grin ). It was considered unsafe by several Nxt devs and technical team to be put in the Nxt core. NxtAT team argued that as each step requires Nxt fees to complete, cost of the attack is linearly proportional to its impact and any malicious codes impact would be manageable. But agreement wasn't forthcoming and led NxtAT floundering. The Nxt devs want to see the effects (and any disasters) in other coins such as Qora/Burst/Ethereum before reconsidering for the Nxt core. The NxtAT team have since implemented the system successfully in Qora and Burst IIRC but neither have managed to gain any traction so far.


More recent analysis by Kushti (a name to respect if you know anything about serious research into POS) who I don't believe was involved in the initial disagreement, thinks delaying NxtAT was a good thing. After studying Ethereum's approach, he is also unconvinced their approach is the best one.


So there we have it, sorry if the truth bombs get in the way of the diversionary narrative some were pushing Grin



tl:dr - Nxt can be Turing complete if it wanted to be through the completed NxtAT project that has existed for more than a year. But Turing complete transactions are not necessary, or even desirable, for most transactions as they are cumbersome for simple things like making payments (why drive around a go-kart track in a 40tonne delivery truck when you can do it quicker and easier on a go-kart?). Nxt devs are taking a wait and see approach, expecting existing turing complete implementations to run into problems. There is nothing stopping the completed, open source NxtAT project being implemented in Nxt in the future once the turing complete concept has been proven safe in the wild.

I can't speak to if NXT as a whole is a scam currency, but my personal experience was that it took basically two days to confirm a transaction. And when I went to make a small transaction to test something out it said my password was wrong.

A block taking two days has never happened before, are you sure you put the transaction through?

Also the Client has no way of knowing what *your* password is. It just takes what you give it, processes it and shows the account it is related to. How exactly did it tell you it was wrong?


When the servers are given a kick, you will be able to try Nxt for free and without needing to download the client or the blockchain here. You can learn the basics (and advanced bits) here risk free.

What happened to TF, any ETA on its implementation? Its surprising that after all this time there is still no TF when it was one of the features promised on launch.


If you understand TF*  == the ability to predict the next block with a high probability... such as said here...

TF is just an ability to "predict" the future. All the other is bells and whistles.

... then it has been implemented since block 30,000 (1st January 2014)

You can see it alive and kicking, predicting the next forger, here



Otherwise you will have to ask a more specific question as I am not sure what else to tell you.

May I please have a list of all the "many other Nxt clones?"

Wanna buy some? Not happy with your Monero? I feel your pain, bro.

I've known NXT's community has forked several times, thus leaving NXT a gutted shell, and wanted some specifics which which to back up that assertion.

NXT - (HZ + NEM + BURST) = 0

I lol'd  Cheesy Cheesy Cheesy

I wish I had more time to goof around on here, reminds of the the Tawnsew days (or even emule  Grin ). I got worried when Taunsew disappeared, nothing galvanizes people like a good troll.

I will just leave this here to make it clear to any developers reading this:

1. There will be changes in fees and permanent message size limit in 1.7. They will take effect in the 1.7 hard fork, in very early January 2016.

2. These changes will break any application that has hardcoded fees of 1 NXT, or uses permanent messages exceeding 160 bytes.

3. *snip* ALL API USERS CAN, AND ABSOLUTELY MUST START UPDATING THEIR CODE NOW. DO NOT WAIT UNTIL 1.7 STABLE IS RELEASED *snip* START UPDATING TO 1.6.2, USE SERVER-SIDE FEE CALCULATION, AND EITHER SWITCH TO PRUNABLE MESSAGES, OR MAKE SURE PERMANENT MESSAGE SIZE DOES NOT EXCEED 160 BYTES.

4. To repeat. Do not wait until 1.7.1 stable *snip* THIS IS THE ADVANCE NOTICE.

Technical questions about the transition should be discussed here: https://nxtforum.org/core-development-discussion/adapting-client-side-code-to-the-fee-changes-planned-for-1-7/

Proposed changelog for NRS 1.7, to give the community time to discuss the implications and any concerns.

In the spirit of keeping the community informed about what is coming in 1.7, here is the changelog, as it is now. All features described are already implemented, this is not a roadmap, this is completed work (for the server part at least, we are still waiting for the UI to be finished and polished).


Coin Shuffling
This feature is based on the paper by Tim Ruffing et al, http://crypsys.mmci.uni-saarland.de/projects/CoinShuffle/coinshuffle.pdf .

Coin shuffling can be used to perform mixing of NXT, MS currencies (unless created as non-shuffleable), or AE assets. Any account can create a new shuffling, specifying the holding to be shuffled, the shuffle amount, number of participants required, and registration deadline. This is done using the shufflingCreate API. The subsequent shuffling steps can be done either manually, by using the shufflingRegister (for accounts other than the creator), shufflingProcess, shufflingVerify or shufflingCancel APIs, or, much more conveniently, by starting an automated Shuffler, using the startShuffler API. Once started, the Shuffler monitors the blockchain state for transactions relevant to the specified shuffle, and automatically submits the required transactions on behalf of the user, performing shuffle processing, verification, or cancellation as needed. To do this, the Shuffler is required to keep the user secret phrase in memory, therefore it should be run on a trusted local machine only. A restart or a crash of the node requires the shuffler to be started again using the startShuffler API, as it should never save the user secret phrase on disk.

To participate in a shuffling, a deposit of 1000 NXT is needed, in addition to the amount of currency or asset being shuffled. Or if shuffling NXT, the amount of the shuffle must exceed this 1000 NXT minimum. If the shuffling completes successfully, this amount is added to the recipient account balance, to allow it to send outgoing transactions (as it is required that only new, unused accounts are specified as recipients). If the shuffle fails due to a registered participant failing to participate as required, or intentionally submitting false data, the participant responsible for the shuffle cancellation is penalized by retaining this deposit and sending it to the forger of the shuffle finish block instead. If a shuffle is cancelled because the required number of participants is not met, nobody is penalized and all deposits are refunded.

Query APIs to retrieve currently running shufflers, shufflings, and shuffling participants are: getAllShufflings, getAccountShufflings, getAssignedShufflings, getHoldingShufflings, getShufflers, getShuffling, and getShufflingParticipants.

If desired, finished shufflings can be automatically deleted from the database if the nxt.deleteFinishedShufflings property is set to true (default is false).

The fee for creating a shuffling or registering in one is 1 NXT, for the shuffling process or shuffling cancel transactions 10 NXT, and for the verify transaction 1 NXT.


Account control for phased transactions
Any account can be restricted to only be allowed to issue phased transactions subject to a specific voting model. This is achieved by the account submitting a setPhasingOnly transaction using the setPhasingOnlyControl API. The getPhasingOnlyControl API can be used to retrieve the status of an account phasing control, and getAllPhasingOnlyControls to get all accounts subject to phasing control with their respective restrictions.

Once set, the phasing only account control can only be disabled or changed with another setPhasingOnly transaction, itself subject to the currently set phasing restrictions.

Note that by-transaction and by-hash voting models are not allowed for phasing control, and setting voting model to none is used to disable the control.


Immediate release of phased transactions on approval
Phased transactions with a voting model that does not depend on account balance (such as by-transaction or by-hash), or by-account with no minimum balance and with a whitelist, will be released before their finish height as soon as approved (in the block in which the transaction causing their approval is executed), if possible. Such early finish is guaranteed for transaction types known to be phasing safe. For others, if the early finish does not succeed due to the transaction failing validation at this height or conflicting with another transaction in the same block, a second, final release attempt will be performed at finish height.


New base target adjustment algorithm
Average block times will be 60 s, with 1440 blocks per day. Block times should practically never exceed 10 min.

Limit of 1000 NXT on minimum forging balance. This applies to the total of the account own guaranteed balance plus any balances leased to it, but not to each individual balance lease. An account with balance lower than the limit can still lease its balance to another.


Account properties
Those are name / value pairs that can be set on any account (except Genesis), by either the account owner, or by another account. Names are limited to 32 characters, and values to 160 characters. Names are unique per account and per setter account, but not globally unique. Account properties cannot be transferred between accounts. The setter of an account property can edit it by replacing its value with another. Either the setter, or the recipient (if different) of an account property can delete it. There is no limit on the number of properties an account can have. Fee for setting account property is 1 NXT for value up to 32 chars, with additional 1 NXT fee for every 32 chars after that.

Account properties are managed using the setAccountProperty and deleteAccountProperty APIs. To query the properties of an account, or those set by an account, the getAccountProperties API can be used.


Singleton assets
Issuing an asset with a quantity of 1, decimals 0, and description length not exceeding 160 characters, will require a base minimum fee of 1 NXT only, instead of the regular 1000 NXT asset issuance fee. For description of more than 32 chars, an extra 1 NXT fee is added for each 32 chars. Asset name for singleton assets is limited to 10 chars, same as for regular assets.


Throttling of unique resource allocation transactions
Asset issuance (excluding singleton assets), monetary system currency issuance, and alias assignment (excluding re-assignment), will be limited to only one transaction of each type accepted per block.


Spreading back block fees for asset and currency issuance
The transaction fees for asset (excluding singleton assets) and currency issuance will be split between the forgers of the current and the previous three blocks in a 4:3:2:1 ratio.


Deletion of asset shares will be performed as a separate AssetDelete transaction type instead of as sending the shares to Genesis. Sending shares to Genesis will no longer be allowed.


Fees and size limit changes

Several transaction types or attachments will have new fees and size limits, to encourage users to utilize the prunable versions when available, and to make fees proportionate to actual blockchain space consumed.

Aliases:
Base fee 2 NXT, with 2 NXT additional fee for each 32 chars of name plus URI total length, after the first 32 chars. Name and URI size limits remain at 100 and 1000 chars respectively.

Messages and EncryptedMessages (non-prunable):
Maximum length reduced to 160 bytes. 1 NXT fee for each 32 bytes after the first 32 bytes. For encrypted messages, the length is measured excluding the nonce and the 16 byte AES initialization vector.

Fees and size limit for prunable messages remain unchanged.

AccountInfo:
Base fee 1 NXT, with 2 NXT additional fee for each 32 chars of name plus description total length, after the first 32 chars. Name and description size limits remain at 100 and 1000 chars. AccountInfo transactions throttled at one per block.

Polls:
Base fee 10 NXT for polls with up to 20 options, and total size of poll name plus poll description plus total option length not exceeding 320 chars. For each option above 20, an additional fee of 1 NXT, and for each 32 chars after 320, an additional fee of 1 NXT. Poll creation throttled to one per block. Name, description, and option length limits remain at 100, 1000, and 100 chars respectively.

DGS Listing:
Base fee 2 NXT, with 2 NXT additional fee for each 32 chars of name plus description total length, after the first 32 chars. Name and description size limits remain at 100 and 1000 max. DGS Listing throttled at one per block.

DGS Delivery:
Base fee 1 NXT, with 2 NXT additional fee for each 32 bytes of encrypted goods data after the first 32 bytes, nonce and AES initialization bytes excluded. Encrypted goods data size limit remains 1000 bytes.

Very good website, it really sums up NXT's roadmap perfectly, and the design makes it user friendly.

I had to tweet it:

The website is 99.9% by QBTC  Smiley

The tweet got over 70 retweets, gotta spread the word about nxt tree and upcoming features.

I advertised my tweet, lets see how efficient will be Smiley

Nice one  Grin

Over 110 retweets now. Any results so far? Let me know so that I can see if this is efficient.



Unfortunately, the 0.1% involvement I have with the website means I don't have this find of visibility. Maybe QBTC with drop by with some stats.

...I see that people confuse Account Control and Phasing. The rule is quite simple: if it's only u who control ur account then it's AC, if other people required for control then it's Phasing [Phased Transactions].

I think, full Account Control is most important feature in 1.7.

I've  been waiting for this feature for a long time. I thought it was originally going in 1.4 Sad

Well it shouldn't be too log to wait now  Grin It will be a big step forward, these are the planned features from Aug 2014.. (as Account Control is being implemented in 3 phases, one already complete, then some of these are live now)


1. Disable non-SmartContract transactions

Removes ability to initiate manual transactions. After they are disabled only virtual transactions initiated by smart contracts (hosted on this account) will be processed. This subfeature is necessary to unlock extra potential of Smart Contracts and should be done before I complete Smart Contracts.

Manual transactions can be enabled again only if a smart contract does it. A possible application is funding an account for a kid who will get access to this account only after some conditions r met (like becoming 18 y.o.)


2. Send money/assets only to predefined accounts

Defines a list of acconts that can be recipients of transactions initiated by the account. Besides extra protection some other schemes can use this subfeature, for example, an escrow service that can send money only to Alice or Bob, but not to himself.

 
3. Enable/Disable "Instant Transactions" mode

Enables/disables "instant" transactions mode described by BCNext here - https://bitcointa.lk/threads/nxt-instant-transactions-with-guaranteed-confirmation.179540/

Pay attention, that it doesn't automatically create IT feature. Mczarnek is working on another IT approach proposed by anon136, but I think that we need legacy IT mode just in case.


4. Allow/Disallow only some outgoing/incoming transaction types

Allows/disallows different transaction types. Besides extra security it's handy to prevent anyone from sending trash assets to ur account.


5. 2FA with hash chains

This brings 2-factor authorization into Nxt. Actually it's possible to have N-factor auth, it's similar to Multisig of Bitcoin, but requires to send two transactions instead of one. This also adds protection against quantum computers.


6. Transfer of everything to another account (at will, dead man's switch, incoming transaction)

Can be used to transfer everything from one account to another. It can also be used to "merge" multiple accounts into one.


7. Setting spending limits

As title says. Can be used for stronger security and also to limit amounts ur wife/kid spends.



Remember, this is only a guide. Features have been switched around and new ones added that weren't (like the cold storage integration). But I think the devs have proved in the last two years that they have the expertise to deliver what they say they will.
