Are all the the features that are outline on the nxt main website integrated in to the currency already? Or are those things just features that are planned to be implemented at some point in the future?

Where does everyone see nxt going? Is the community actively promoting it as an alternative to bitcoin, or are they taking a different approach?

Where is the best place to buy nxt?
bter

You should try https://sharexcoin.com/market/NXT_BTC. They don't charge a .5% fee to withdraw your NXT.

I'm looking for a serious NEXTer in america or australia which wakes me up in the night hours with a phone call, if the NEXT price drops! I would do it, of course!

If interested, please pm me  Roll Eyes

Are you serious???

Why don't you just install this app in your smarphone?

https://play.google.com/store/apps/details?id=com.mobnetic.coinguardian

 Roll Eyes

I did not know that there is such a thing! Is there this app for iphone?  Huh Shocked

I have "coinbits" installed on my iPhone. It lists prices and allows you to set alerts. BTER is one of the exchanges it gets prices from.

So, yes is the answer.

Both pending for over 4 hours now.

Strange. Did you put in a support ticket?

The tips idea is interesting - i am currently speaking with a restaurant that wants to accept it, we just need to get it integrated into their system - but tips could be very easy...i am going to pursue this further

Of course a mobile wallet with a bar code reader and the wait staff with a QR code either on their name tag or printed on the receipt would make it very easy. Wink

I had user barrabas on ignored, now I see why in the quotes  Grin

Forged 4 blocks this week only run it for a few hours a day with 300K NXT so, argument invalid



Cool, now I just have to buy 300K NXT. Now where did I put those extra 27 bitcoins? Wink

If you had 30k NXT you can forge 1/10th of his blocks. So 0.4 Blocks worth 0.4 blockfees and 0.4 NSC. Still 4-6 NXT worth!

well, I just (10 mins ago) made my first purchase, 4000 NXT (how will that forge?). Seems like a drop in the bucket. I bought them on ShareX. The Ask's seemed a bit high, but BTER's seemed to come up pretty close to meeting it, so I figured, what's 15 or so sat per NXT? It worked to about $.035 USD. Yea, I know, I'm a bad trader. I'm thinking of converting my NAUT to NXT too. NXT seems so much more exciting and useful.

Decisions/decisions.

if you bought at 0.035 $ you are a genious Wink 0.053 I guess.

4000 is not much, son you have to know that you will probably lose money with electricity cost. You could lease your forging power but that costs 1 NXT, and if my intutition is not completely wrong, you will forge less in 1 month (ignoring the NSC).

You misread my message. Wink I said I spent .035 cents in total (9150 vs 9010) more buying at ShareX than I would have on BTER. Wink

Yes, I was pretty sure $4k wouldn't forge me anything. Wink I'm speculating on price and HODling (as some here like to spell). Might by a few assets too, like the auction site and maybe something else. Not sure yet. I've been adding $x a month to my portfolio, 50% BTC and 50% alt-coins.

Oh, and my PC is on 100% of the time anyway, mostly folding at home. So, keeping a few PoS wallets open doesn't add anything to the cost.

Are there any plans for a FEE Schedule on ShareXCoin? I know the trading fee is listed. But, what about withdrawal/deposit fees? Also, I assume you will need info on USD transfer methods/fees.

Just a suggestion.

I had though that was a typo from an earlier contest and they forgot to change the date.

There's lots of incentives that could be done.

How about store loyalty type programs? For example,  A gas station could send X NAUT to your wallet for every gallon you spend. Loyalty programs have the benefit that a vendor doesn't have to accept payments in NAUT or worry about converting it to Fiat. This program also spreads NAUT to more people.

How about a restaurant that has wait staff willing to accept tips in NAUT? (doge is very popular for online tips)

The idea is to spread the word about NAUT, get people using it. Once people have or know about it, they will start asking vendors to accept it rather than cash.

I don't know, just throwing some stupid ideas out there.
1692  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [NXT] Nxt - Official Thread on: June 02, 2014, 08:37:24 PM
I have one question.
Wasn't there a problems running NXT software on VPS because of security risk?
I remember in the long locked thread people were advised to not keep the wallet open and forge on VPS
as this was described as insecure.
Huh

Can someone deny (clarify) this?
Thanks.


There is some risk, that's why I posted a safe way of doing it Smiley

Thanks I will mark your words. Smiley
Based on this I have more questions related to NXT or similar coin security.
The question is how securely implement a service based on NXT for example
a website for something would need to do automated payments to users.
To be able to send a payment the wallet needs to be unlocked with a password and
a transaction needs to be sent out.
If the website is hosted by some hosting provider does ti mean that the wallet needs to be
hosted there as well? The script php,asp,python or whatever needs to unlock the wallet
and send the API request.
How this kind of things should be implemented to avoid security risks where the passwords shoud be stored?!
I think anyone that has access to the hosting account or VPS account could hack this or not? what are you suggestions to avoid security risks?

Thanks.



Not really.

You can set up a message buss or queue. The web site sends a message to the Queue. The wallet monitors the queue. This means the wallet can be hosted on a separate server. 

There are always points of failure though. For example, what if someone gained access to the web server and got the key it used to sign messages sent to the queue. Same issue if the wallet service blindly sends everything.

This is usually mitigate with a HOT wallet and a COLD wallet. The HOT wallet is limited to a certain amount of coins. Anything over that is sent to the COLD wallet automatically. This limits and fraudulent claims to the amount in the HOT wallet.

But, bottom line, security should be JOB ONE for any web site that automatically sends coins. Automatically accepting them is so much safer, since there is no need for access to the private key to do this.
1693  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [NXT] Nxt - Official Thread on: June 02, 2014, 04:54:09 PM
Sorry  5,1 NXT per block  Huh Huh

When there are more transactions in the network and 1 NXT costs more, it might be profitable. Under 2 conditions: 1) you buy as many cheap NXTs now as you can to increase your chances; 2) you keep your NXT running and forging. Think of investing into NXT as buying hardware for Bitcoin mining if you like Smiley Even if you don't buy many NXTs, you still can get lucky, you don't need to run anything else, but your computer, which you run anyway. All you need is a browser. When you switch it off, you switch it off, when you switch it on, start forging and maybe you get lucky. You can also lease your NXTs to a pool and get steady little profits.


Thank you for all the replys!

at work I can not install the next client! Is there a possibility for forging anyway? Online Wallet?

The only online wallet currently available doesn't currently support forging.

Can you not just leave your wallet open and running on your home machine?
1694  Other / Beginners & Help / Re: Understanding Public and Private Keys on: June 02, 2014, 04:25:38 PM
how about blockchain?
i don't see any private key?

Sorry for all the question, i'm just want to learn more about bitcoin security  Embarrassed

The blockchain.info website creates an indexed database of all transactions that have ever been seen on the bitcoin network.  That allows them to create a website where you can search for and see transactions, addresses, and blocks.

The blockchain.info wallet service stores your private keys for you in encrypted form in their database.  When you want to create a transaction, they send these encrypted private keys to your web browser where their are decrypted with your password.  Then javascript software running in your web browser handles the creation of the bitcoin transaction and generating all the proper signatures.

so do you mean my private address well kept and secured from them with only my password, etc?

Yes, the blockchain.info mywallet "server" never knows your PK's, the wallet in encrypted in your browser locally and then uploaded to their server. You can also use a secondary password which means the password your wallet in encrypted with is different than the password that you login with to d/l your wallet.


locally? are you pointing at cookies?

Yes locally. You can inspect the cookies. There is a cookie that remembers your wallet id. that has nothing to do with the encryption.

But, other than that, the blockchain.info wallet is all javascript that runs locally. It uses the blockchain.info API to get your balances and to send money. You can view the blockchain wallet source code on github.

1696  Other / Beginners & Help / Re: Understanding Public and Private Keys on: June 02, 2014, 04:10:29 PM
damn, i still don't understand the meaning of having public and private key.
could someone explain it with simple sentences?


Private key of A = A can spend the coins
Public key  of A = you can get the address and send coins to A.

If you will a public key is (are many) padlock(s), they allow you to lock the coins for someone else without having the key.
The key to unlock the coins is the private key. There can be several copies of the same private key but thats not wise. Thats why its so important to take care of your wallet. It has your private keys.

so for example i buying pizza, and i pay them using private key?

and if i'm the seller i give them my public key?

Unfortunately, some people use the words "public key" to mean "bitcoin address".

A public key is NOT a bitcoin address (even though many confused people will tell you that it is).

You typically will never see and never know your public key.  The public key is used by the bitcoin protocol to verify digital signatures.

If you are buying a pizza, you will use bitcoin wallet software to create a bitcoin transaction that "sends the bitcoins to the pizza seller".

The bitcoin software will handle all the technical details for you.

If you want to know about those technical details:

The bitcoin wallet software will choose enough unspent outputs that you have received in the past so that the sum of the value is more than the amount you are "sending to the pizza seller".  These will all be listed in the transaction as "inputs".

Then the bitcoin wallet software will create a new output that assigns the desired value to the pizza merchant's bitcoin address, and a second output that assigns any extra amount from the sum of the inputs to an address in the bitcoin wallet.

The protocol requires digital signatures for each of those inputs proving that you have authorization to spend them.  The wallet uses the private keys to compute ECDSA digital signatures.  This is the mechanism that prevents other people from spending, or stealing your bitcoins.  Since they don't know your private keys, they are unable to generate the proper digital signatures, and the rest of the network just ignores any transaction that anyone else tries to create that would spend your bitcoins.  Of course, if a hacker can gain access to your private keys, then they can load them into wallet software of their own, and spend your bitcoins.

There is a mathematical relaitionship between the private key and the bitcoins address, but if only works in one direction.  If you know the private key, then you can compute the bitcoin address.  If you know the bitcoin address, it is impossible to compute the private key.  This means it is safe to give your bitcoin address to people (so they can send you bitcoins), since they can't figure out your private key.

The digital signature is also mathematically computed.  The particular mathematical relationship means that a signature can be verified without the private key as long as you have the public key.  Bitcoin includes the public key with the signature.  That way the entire network can verify the signature with the public key, and then can make sure that hashing the public key results in the correct bitcoin address.

how about blockchain?
i don't see any private key?

Sorry for all the question, i'm just want to learn more about bitcoin security  Embarrassed

That's the whole point of "private". Wink

I'm pretty sure there are no keys on the blockchain at all. Just transactions that are signed.
1697  Other / Beginners & Help / Re: Why does it take so long to confirm? on: June 02, 2014, 03:16:37 PM
Confirmation time really depends. I had transactions which had 1-2 confirmations in 3 minutes, and transactions where I waited for around 10 minutes.  When this a big transaction it really does get on your nerves Smiley


It also depends on when you send the transaction. If you send it seconds after the last block then you are probably going to have to wait ~10 mins for your first confirm. If you send ~9 minutes after that last block, then you are probably going to only wait ~1 mins for your first confirm.

If you trust the network then you shouldn't be nervous about it. once your tx shows on the blockchain you can be sure it will be confirmed.

Can you still buy FeeShares with ShareCoin?

I thought that was no longer possible and the only way to buy FeeShares is with bitcoins.
there are 10000 feeshares for sale.sharex just sold around 2000+.zip said he will reopen the share/fee market 2-3 months later.

Thanks, I found it confusing because I could not find a share/fee market when I looked.
sharecoin-feeshare market was closed , so you can't find it now.
It will be reopened when the dev think it's necessary.

It will be opened when it IS necessary. Does anyone remember how many FeeShares were sold? I recall it was around 500 or so.

2000+

I pretty clearly remember the original amount put up for sale was 2000. So, I'm certain it wasn't more than that. It seems the FeeShare page is no longer on the exchange though.

Quote
5% (5,000 FEEs) were sold to the public on May 10, 2014 when ShareXcoin first launched.

The page is here: https://sharexcoin.com/interests/about

Right, forgot this info was there. The fee_shares/about page is now a 404 though.

SO, it was 5000 originally available, and not all of them were sold. But, I thought the number was under 200.

I'd still like to see the transparency info that was promised, IE, number of FeeShares owned, payments per share per day, etc.


To be exact, 1035 FeeShares were sold Smiley

Thanks. (and that was a typo, should have said less than 2000.)
1699  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][SHARE]ShareCoin - Pure POS - The only coin backed up by a real bussiness on: June 02, 2014, 03:10:39 PM
But as a way to promote share sales it is a good suggestion.

It skews the ability to calculate an ROI on the FeeShare.

Let's say I evaluate the annual payout on FeeShare (which I plan to do soon) to establish a price I want to pay assuming a certain percentage of return. I figure out my buy price and put bid orders out. I manage to buy 100 FeeShare at the price.

Now, 4 months later another 2000 FeeShares are sold. My return calculation is now meaningless. I have over paid for the FeeShares based on the return I was looking for.

Also, with the change you suggest all the FeeShare holders will do everything they can to discourage FeeShare purchase. The less FeeShare holders, the less people trying to get more folks to trade on the exchange, the less money the exchange makes and the less FeeShares are worth.

The best way to promote SHARE sales, it to get more people trading at ShareXCoin, which makes FeeShares worth more which makes SHARE worth more.

Just curious, if bitcoin takes sometimes like 1 hr of confirmations.

Do other coins beat this ability? or is it for alt coins as well.



90% of the alt-coins are a fork of Bitcoin. The only changes are generally block time and block reward. It seems most alt-coins have a 60 second block time. I'm not sure how that converts to the security wrt 6 confirms.

I guess the alt-coin devs don't expect a miner on mars, or even the moon any time soon. Although, I hear the BTC block chain is, or will soon be on the ISS.
