Hi Guys,

We've just launched Bitcoin Cash support in StrongCoin wallet.

https://strongcoin.com/blog/bitcoin_cash_is_now_supported_in_strongcoin_wallet

I donated years ago and have completely forgotton about this.

Here's my current address. 1BXyDcQJhAgm3U9xyPY9JL8AtMVpygxACY

Thanks for your efforts.

I can be contacted on support@strongcoin.com if you need to run any verification.

PM'd but no response.

Hi.

I run BitsinoDice which is open source. https://github.com/Bitsino/BitsinoDice

Basically, no site starts out passive, but may become passive later. The flow of money is simple.

Visitors -> Registrations -> Deposits -> Profit ?

The problem is firstly getting traffic. Secondly a dice site runs a house edge typically of 1%, however this is an average over many bets, you could lose the entire capital of the site through a few lucky customers.

So even if you are able to get a constant flow of traffic you have to look out for security issues. A security issue could also wipe out your profit.

Good luck.

It was removed due to concerns over security, can't remember the details.

There's an article here. http://www.coindesk.com/hacker-returns-225-btc-taken-blockchain-wallets/

If you click on the ID, you get the verification popup. The calculation will match the way we calculate the roll in the back end. https://github.com/Bitsino/BitsinoDice/blob/master/app/models/bet.rb#L66

Open Source

We believe a dice site is only really provably fair if everyone has access to the source code.

You can view our source code over on github. https://github.com/Bitsino/BitsinoDice

You’re welcome to clone the code and run your own site if you like. Good luck.

Security.

We are the first gambling site as far as we know to implement a multi signature solution for customer deposits. All deposits are pulled into a multi sig fund each day. And we pay out from the same fund with sign off from the CTO and CEO of bitsino.

Any Questions...

Just ask.

It's possible more than 1 miner would solve the block at 1 time. So if the block is prevented from being signed as you mentioned above, another miner might get lucky.

The block that gets signed is the one that enters the blockchain.

What makes you so sure they will honor the buyback price.

No because the genesis block is hard wired into the NXT server and all the coins from the genesis block were sent to the original investors.


I'm not an NXT developer but I have looked at the code.

Let's say I have 25% of NXT coins. And I want to mount an attack. I need to do the following.

1. Wait until I am selected as a forger.
2. Create 2 blocks, one for the network and one I hold back.
3. Continually add more blocks to the block I hold back. This is my chain I will introduce later as my attack.

The problem is step 3. To add another block to my held back block I need to be selected as the forger for that block too. However forger selection is based on the hash of the previous block and my account address.

Neither of these I can change quickly enough to be sure I generate the next block. So my probability of being selected to build the next block is 25% for each block.

I read carefully what DaT contributed, but I can't apply his attack to the code as I see it.

That's not how I understand it from looking at the code. You don't so much choose who forges next, rather the node can decide wether a block is valid or not.

For the block to be excepted.

1. Hash the hash of the previous block.
2. Take the first six bytes of that. Let's call that rnd_selector
3. Take the current time since the last block in millis i.e. 100000
4. Take the effective balance of the account that generated the block.

If balance * time_in_millis > rnd_selector then the block is valid.

Code here https://bitbucket.org/JeanLucPicard/nxt/src/046e59e4df43309a37c2789efd39dba4a873bbe2/src/java/nxt/Generator.java?at=master#cl-160

Basically any account that meets the above criteria can generate the block, if no one can (or someone is offline)  time_in_millis will grow and eventually someone will be able to generate the block.

So to build a competitive chain in NXT, I would have to alter the block message so that rnd_selector keeps on selecting one of my accounts.

The above was drawn from the code so perhaps one of the NXT guys would clarify if this is inaccurate.

This makes the situation worse does it not ? Now NXT owners will lease their coins to a handful of operators to earn fees.

These operators would be perfectly placed to mount an attack. They would have a % of the POS coins and they can mount a double spend attack with pretty much zero risk as identified by DaT.

It would be nice to get a clear statement from the NXT guys as to wether this is possible or not.

 

Demonstration of connecting the android app to an online wallet here

http://youtu.be/TSHYu0fCEAg

1. The wallet requests a master public key from the andoid app, after that a 2 of 2 wallet can be created.
2. User creates a payment and signs it in the online wallet (by using his passphrase)
3. Transaction is created, waiting for user to sign (for the second time) with the android app.
4. User signs with android app.
