what for a store?

The problem is to open the slab you have to bust it up quite a bit. I have cracked probably 40 slabs so far 

I may be a bit confused, but what stops gravitate from selling the coin loaded with 1BTC to a puppet account of his own?

So to replace step 4:

Have each coin labelled 1 to 10 (or any arb number) and then have an escrow generate a random sequence of the 10 numbers (or again, any arb sequence length) which the escrow keeps to himself. Then once all coins are sold/reserved, they get sold and shipped according to the number they reserved (people will still reserve in numbers 1-10, but the escrow will match it with the sequence). 

This isn't fool proof, but I guess it would be harder this way (?)

Great work,
Hope to be able to purchase engineering samples soon and play with it

So since these chips are so efficient and powerful. Why sell them and not just mine themselves instead?

Yikes I would say kraken. I would hurry up while this price lasts..

Avalon and kano.is are having another great miner give-away!

Over the next 5 months we will be giving away 1 Avalon A6 per month.

Be a miner here with more than 300GHs - and less than 250THs - and you could win one of the 5 Avalon A6 miners!

Each winner is the first miner to find a BLOCK!!! and meet the conditions listed below.

Details:

Only one Avalon A6 per winner.

Each month starts on the 1st day of the month at UTC 00:00 timezone.
The first month, January, starts on the 18th at UTC 00:00

If for any month, the miner isn't won, it will continue into the following months until someone wins it.
Each month adds a new miner to be won, so during some months there could be more than 1 winner if there was no winner the previous month.

Avalon will be supplying and shipping a miner to each winner.
It will be an Avalon6 x1, 4-pin-cable x2, AUC x2, without PSU - as shown in the pictures below (but silver - not black)
The Avalon A6 does 3.5THs +/- 5% at approx 1100W at the wall.

[PICS]

Avalon is great with cgminer!
The master cgminer git is kept up-to-date by Avalon submitting their changes, and they incorporate all the master cgminer changes!

Details about the Avalon A6 can be found on the bitcoin wiki: https://en.bitcoin.it/wiki/Avalon6

Your 'Workers'->'Shift Graph' must show an average of 300GHs or more - and less than 250THs - on the red average line - for the sum of all your miners.
So if you want to be a winner you better make sure you are already mining 300GHs or more on your account now.
Note, of course, I can see anyone's 'Shift Graph' including address miners.

Now, just in case we do find any orphans, the orphans will also count as winners as long as the share isn't submitted too late.
The late timelimit is of course any time before, but also up to exactly 2 seconds after the pool sees a block change, according to the pool logs.
No adjustments or arguments about the exact 2 second limit.
No miners should be submitting blocks that late, so it's not a special requirement.

You will have to supply an address that Avalon can ship it to via EMS or DHL.
It doesn't have to be your own address, but it has to be possible for them to ship to your chosen address.
If you cannot supply an address EMS or DHL will ship to, then the prize will be awarded to the next winning block finder.

If you mine to an address, you'll need to sign a message with the winning address, to identify who is the contact to claim the prize.

If you don't want to supply contact details to ship it to, then the prize will be awarded to the next winning block finder.

One last important thing - my decision on the winners are final.
If there is any confusion or misunderstanding about how the winner is chosen, I retain the right to choose who the winner is in the event of any disagreement.

i like the give away, but dont really see any chance wining it with all the 50-250th rigs out there
