Why is it flying on Bittrex if it is defunct? Is there something i am misssing?...

Trades are still functional because they don't actually involve a wallet. Exchanges are banks and trades run on debits and credits to a ledger (not actual coins).

But how can anyone trade it, if you're going to sell the coins, you need to take them from your Bitrex wallet?
And price only moves if it's traded, so I don't get it.

Seems as if the developer is working on the final stages of an upgrade.

Okay if Bittrex and Cryptopia have halted the wallet. Am I missing another exchange somewhere where the price of the coin is moving and frankly fooling Coinwarz as the most profitable coin.

Coinwarz has been stuck on the old Bittrex price since Bittrex shut down their wallet and Coinwarz has, thus far, ignored all notices that the coin is defunct. :/

Both Cryptopia and Bittrex have said they are working with the devs to resolve this. Here's to hoping.

Cryptopia said they are investigating 51% is it an attack or is it sedgwit anyone know?

I've heard claim after claim after claim of "double spend" or "51%" attacks on dozens of coins and not yet seen a single shred of proof to back any such claim. Undecided

Yep and Bittrex reported it almost 2 days before Cryptopia did anything.

I sent coins from my UNB desktop wallet to Cryptopia just before they shut down the market, my coins are currently marked as unavailable in my Cryptopia account :s

In spite of all this, it seems to be flying on Bittrex the last couple of days. Hopefully we will be able to send our coins over there in due course.

Any update on this devs?
I have some coins in Cryptopia too which cant even be traded let alone transferred to different wallets.
Getting quite frustrating.

Anyone have any idea how much longer the Bittrex wallet will be down?
My coins are trapped :s

Bittrex's official answer is:

Quote from: 'Ryan @ Bittrex'

The issue that was present with this coin leads to loss of integrity with the wallet we cannot allow coins to move in/out of the wallet until the development team fixes the wallet. Turning this wallet on could lead to the loss of funds for many users due to the nature of the attack. Please contact the development team if you have issues with this.

There is nothing I can do for you at this time, as this issue is waiting on the developer to be resolved.

In other words, "UNB is toast and you're feked for your coins."

Oh no.

Devs?? Where are you up to with this?? Thanks!

Any idea how to backup a wallet from mac and load it onto windows?
I have been using the mac wallet but have run into some problems with it where it will not download the blockchain and i want to move my coins to a windows based wallet (i've left the wallet open with an active internet connection for days and nothing has progressed).
Appreciate the help!

Shut down any UNB wallets running on either, then just:
Move the wallet.dat file from ~/Library/Application Support/Unbreakablecoin/ on the Mac to C:\Users\YourUserName\Appdata\Roaming\Unbreakablecoin on the Windows PC.

THANK YOU!

Feathercoin was heavily attacked years ago, they really wanted us dead. The only way we managed to survive was to implement realtime checkpointing. Normal checkpoints are coded into the source like in the Bitcoin source below. It is simply a block number and its corresponding hash, clients will only connect to a chain with those blocks.

https://github.com/bitcoin/bitcoin/blob/master/src/chainparams.cpp#L148

Realtime checkpointing is where checkpoints are broadcast at a certain depth, the depth we used was five, this prevented an attacker from replacing the chain any deeper than those five block, exchanges then use a confirmation depth of six and then the coin cannot be used in a transaction reversal attack by replacing the existing chain with a longer one.

I have linked in the code for this below on Deepcoin, I link that coin as the commit is relatively neat and encapsulates everything required.

https://github.com/Deepcoinbiz/Deepcoin/commit/43413fac89da1db064668e7e4dd5bd6c6036dfb4

I hope this may be of some help. All someone needs to do is add checkpointing to the coin, compile binaries and set up a node to broadcast checkpoints. People get funny about having a node broadcast checkpoints but the only other options seems to be delisting, there are elements of centralisation from source code developers to DNS seeders, sometimes the trade off is worth it.

Bittrex now posted this: UNB blockchain experienced a double spend attack. We are working with the development team on a fix.

Any chances to fix this problem? Dev, are you here?

There's a bit of code in the various repos where it seems someone might muck up a new Bitcoin fork into something that Bittrex will accept.
