This might push people away from scrypt altcoins. An arms race for mining litecoin and dogecoins helps us, right?

Isnt this price/MH much more attractive than regular ATI-based mining rigs?  With a 6 card rig, costing around 6000 or so, you might get 6MH/s.  They are advertising min of 100MH/s for only 10G.

This will be interesting.

That's not funny opticalcarrier  Grin and no I did not as a matter of fact. Now I am starting to question whether we are in a simulation.

So I was brainstorming the decentralized sports betting idea with my friend yesterday, and I've got some new ideas. Can smarter people than me give me some feedback? These ideas might be really dumb, because I'm not a programmer and I don't fully understand how everything works.

1) A parallel blockchain that contains the history of scores generated by a crawler that pulls data from ESPN, Yahoo Sports, Google, etc and crosschecks the data against the sources. Users of the betting service must somehow reference the correct score history when placing bids for a new bet. After a certain number of confirmations (ie when the future bettors come to a consensus on the correct score history), the old bets are paid out.

2) A parallel blockchain that contains the history of scores generated by a crawler that pulls data from ESPN, Yahoo Sports, Google, etc and crosschecks the data against the sources. Users of the betting service must submit corrections to the blockchain, to be verified by "miners" which are rewarded for the verification (somehow, to be determined). If you submit a false claim for correction, you get penalized in a big way.

These two ideas are trying to decentralize the score reporting portion, so that payouts can be automated without trusting a 3rd party to correctly report the scores.

if these sporting bet can be done in a 100% decentralized manner, that would be so huge for Nxt!

The main problem is "how do you trust" the chains reporting?

Basically "block chain tech" can only accurately report on "other block chains".

how come this type of thing doesn't work on bitcoin clones, what's different there? (Or does it?)

Bitcoin signs each input. Nxt doesn't have inputs.

What do you mean by input?

How?

getTransactionBytes in Nas + broadcastTransaction in Nxt.

I guess after 1440 blocks it's no longer possible to do broadcastTransaction? (too old)?

Depends on deadline. Default 24h is long enough to do the attack successfully in 99.9%.

Because there is no brainwallet, so all address are different

That's what I thought. Though collisions are always possible Wink

and What is up with all the Asset Transfers? And I couldn't send testNXT last night or this morning from a newly created account, getting the "Unknown Account" error.



Okay Nxt Community here is a quantum riddle;

My real NXT account number (Public Key) is 14730376987822377578 on NXT Mainnet. I have never used my real NXT passphrase on NXT testnet. However,   14730376987822377578 exists on NXT Testnet.

Yesterday, after I asked for TestNXT on this thread; 18232225178877143084 sent me a 1,000,000 + 1 TestNXT.

While testing this morning, I sent 1,000,000 + 1,000  TestNXT to 14730376987822377578 which showed as a valid public key and appeared to have transaction success.

Upon looking at the history of 14730376987822377578 from NxtTestnet, I see "This account has a balance of 1'063'416 NXT" ; 1,000,000 being the TestNXT transferred this morning and 63,416 an old real NXT balance of real NXT account 14730376987822377578.

And even more bizarre, looking down into the transaction history I find dozens of Asset transfers between 3/11/2014 and 3/14/2014 all to the same account number 18232225178877143084. WHICH is the SAME TestNXT account that sent me 1,000,000 TestNXT on 3/19/2014.

Maybe I need another cup of coffee.






did you take a ride with the ambien walrus?

The newly created account error was just a bug in my code Wink I will upload new version later today that fixes it.

So if *more* NXT can be created by "broadcasting a test net tx on main net" then that is a security hole.

How?

Nxt transaction sigs only care about the account id's (not say something like the "genesis block id") so a "clone" (such a test net) in which account #'s that *match* main net (most likely due to using the same password) means that you can *steal* NXT by just broadcasting a test net tx on main net.

(this issue will also apply to "parallel chains" if and when implemented)


well, isn't testnet one kind ?!

You can't create new nxt, it has to be in the withdrawal account.

Should not if you add some kind of field to transaction that signifies the chain it is on.
