Nxt General Discussion / Re: Lastpass hacked.
« on: June 17, 2015, 02:49:09 am »
But I thought with lastpass your passwords were stored locally..

With Lastpass, your data/passwords/usernames/forms/etc are encrypted locally using AES-256 and that encrypted data is stored on the cloud. Lastpass never sees any unencrypted data.  As long as your master password is strong, you don't have anything to worry about.

i know that i will never ever be able to cash out the NXT that i have in the said account without risking my anonymity.

Shapeshift.io doesn't require an account.  Use shapeshift to go from NXT to Monero.

Have we run into a serious problem or not? Not sure I understand!

Thx,

I not too concerned about it at this point as transactions are getting into blocks, but in a haphazard way.  I'm sure JL will have it sorted out soon.

Yup, something is very wrong with MainNet. I've just put in a test tx, about 5 blocks ago, and it's not being incorporated into a block.
Panic now.....
the last block with tx doesnt seem to have any tx that are too strange, so odds are it is something in the unconfirmed tx pool that is preventing any tx from being included.

good news, if it could be called that is that within 1440 blocks whichever unconfirmed tx is causing this will expire.
but of course this means there is a tx (or combination of tx) that can cause this, so we need to get to the bottom of this.

Transaction 2518387193725106845 in unconfirmed transaction list seems weird. 

Nevermind.  All unconfirmed marketplace purchases look the same to me.

Edit 2: The block at height 407173 (id 12780479928851570326) was generated with 105 transactions but the ones just after have zero and there are still unconfirmed transactions in the queue.  Neat.

ORA / Re: NAS diaspora
« on: April 06, 2015, 10:55:09 am »
Quick update:

Haven't completed the NAS utilities yet, but still plan to do so.  I apologize for what should be a day or two of coding has taken so, so long.  Life has decided to throw a bunch of bad stuff at me these past couple months and I'm still sorting it all out ATM.  Am moving house at the moment also, so I may go off-line for a bit but I'll be back to complete this project just not sure when.

Alternate Cryptocurrencies / Re: Is it worth investing in NEM?
« on: April 04, 2015, 12:37:54 pm »
but then I am just a simple java programmer, what do I know.

Is this becoming a meme now? Everyone being simple and all.

... thinking of a catchy language to be simple in ...

I'm just a simple person. 

Oh, wait... that's not ... er..

c) "transmit a private key" this sounds like a really bad idea, I must be misunderstanding. In any case NXT allows to lease forging
Of course only private keys with zero balance are transmitted to harvest on a remote NIS.

Is it really sending actual private keys, or is this just simplified speak?

I ask because sending private keys shouldn't be done even for zero balance accounts because the same can be done with a transaction type that says "the account Y's private key can be used as a substitution for my private key in the case of signing block generation and only that case." which is a lot safer than giving away a private key, an operation that can never be revoked, and serves the same purpose.

Drop Zone: An Anonymous Peer-To-Peer Local Contraband Marketplace
 
Abstract. Drop Zone is a solution to the problem of restricted sales in
censored markets. The proposal is for the design of a protocol and
reference client that encodes the location and a brief description of a
good onto The Blockchain. Those wishing to purchase the good can search
for items within a user-requested radius. Sellers list a good as available
within a geographic region, subject to some degree of precision, for the
purpose of obfuscating their precise location. Goods are announced next to
an expiration, a hashtag, and if space permits, a description. Once a
buyer finds a good in a defined relative proximity, a secure communication
channel is opened between the parties on the Bitcoin test network
(“testnet”). Once negotiations are complete, the buyer sends payment to
the seller via the address listed on the Bitcoin mainnet. This spend
action establishes reputation for the buyer, and potentially for the
seller. Once paid, the seller is to furnish the exact GPS coordinates of
the good to the buyer (alongside a small note such as “Check in the
crevice of the tree”). When the buyer successfully picks up the item at
the specified location, the buyer then issues a receipt with a note by
spending flake to the address of the original post. In this way, sellers
receive a reputation score. The solution is akin to that of Craigslist.org
or Uber, but is distributed and as such provides nearly risk-free terms to
contraband sellers, and drastically reduced risk to contraband buyers.

What is the story about simcoin and smaragda?

I don't know the whole story but I got a PM on BTT from smaragda a while back telling me that I was an accomplice to theft since I held simcoins.  This was confusing to me so I checked smaragda's post history and saw his NxtChg thread.

From what I understand, smaragda claims NxtChg (simcoin dev) locked him out of the simcoin and game exchanges that NxtChg runs while refusing to refund the BTC smaragda deposited on these exchanges.  I don't know if this is true.

I attempted to diplomatically engage NxtChg in PM on BTT in regards to these claims with the hope that the matter could be resolved but he didn't reply to my three PMs except for one in which he replied with a sarcastic one-liner.

That's all I know of the matter.

I own the dotNXT.org domain.  If anyone hosts software, wiki, howtos or the like related to the NXT TLD I can point dotNXT.org to it.

Cryptsy never failed me. It got a lot of shit thrown at it, but it never lost a single coin.

Same here.

I stopped using Cryptsy because when something goes wrong, a support ticket can take upwards of a month before a human looks at it.

Are you implying that the BTC PoW isnt the perfect implementation that can never be improved?
Wouldnt that mean that scientific progress would be have to be tolerated?
maybe that thread will be move to the graveyard section of the forum

Ha!

If I understood my first skim through the paper that is basically how the skycoin software deals with a bad actor: follower nodes can remove trust from their bad-actor followee thus delegating him to his own dusty corner of the network where no one will visit him.  ;)

Figure some here might be interested in this:

Skycoin consensus paper:  http://arxiv.org/abs/1501.06238
"Simulations also show that the algorithm can
tolerant collusion of 15% random nodes or 2% top influential
nodes committing attack of the strongest type."

From https://bitcointalk.org/index.php?topic=380441.msg10532946#msg10532946 :

From simulation under the strongest attack, our alg can tolerant attack committed by 2% top influential nodes or 15% random nodes.
I had read that. Isn't that much less % than a 51% attack?

I understand we can't precisely compare the two, since your model is a different structure from PoW. The complexity here is beyond my comprehension at this moment.
Yes. It is less than 51% attack. This is key.

There is a trade off, as you mentioned before. We allow a smaller number of nodes to dominate the network, to avoid the double spending attack. So the colluding nodes can determine future blocks, but they cannot double spend or rewrite history!

So we allow a DDoS attack, but prevent double spending! That is the trade off. You cannot have both in any algorithm. Any algorithm that prevents DDoS makes the double spending easier and anything that prevents double spending makes DDoS easier. You cannot have both.

If the nodes are very corrupt, if they start holding network hostage or colluding, then people can identify those nodes and begin pruning them from the network. That is important. So Skycoin tolerates DDoS, but disallows double spending. DDoS is merely annoying, with someone refusing to put your transactions into a block, but double spending means reverting transactions that have been executed and spending the outputs to new addresses.

Re-read that last paragraph.  Their coin has active defenses against attack -- their software can force a bad actor off their network.  I suspect once the general BTT audience gets a wind of this it will generate a lot of hate from those with a bitcoin mindset.

So, it seems Google Wallet is no longer going to support payment for digital goods after March 2nd:

https://support.google.com/wallet/business/answer/6107573?hl=en

Seems like a good opportunity for Nxt with the SuperNET extension to be able to fill this role from top-up to payment if we can make enough noise to get noticed.  Any ideas?

BTER is open, I can log in and see 3 balances: CNY, USD and NXT.
Cannot withdraw any NXT, and my selection of crappy NXT clones are nowhere to be seen yet.

Will be interesting to see what coins can be recovered in the next few days.  I'd already figured I'd lost all my coin that was sitting in open orders on there, but perhaps only the BTC is lost.  <shrug>  Removing the BTC in orders, I should have various alts worth somewhere around ~0.85 BTC together.  Would be nice to get some of that back but I'm not going to count on it.
