They're certainly less dodgy than mine

They look similar spec to those on the board reviewed by @2GOOD. His cooler fins were only ~8C above ambient (i presume at 100GH), but I think his has copper spreader on bottom.

I got these, touch and go but I may just about get away with it:

You mean 200 boards? 80 TH  WOW.

I don't need fans but it sounds like a good plan for anyone who doesn't have them yet.

The ones I got only have 2 * U heatpipes, rated at 120W in enclosure, they should just be good enough, may have to lap all 48 blocks though. Already got my Shin-Etsu thermal paste.

P.S. Are you using old DELL server PSUs? They are very efficient. I'm currently converting 12 * 750W PSUs and soldering in 12V 60 AMP cables ( I can't imagine doing 200 ). These PSUs stock sound like a jet turbine hair dryer but you can quieten them down alot with a mod.

I know, the "Next Week" groundhog day coming to an end hopefully.

When we receive boards we should post here along with TechnoBit order# to give the rest of us something to watch.

I think you're a little before me @sorehammer, I'll post mine also, we all should.

Yes, hundreds of Chinese eBay purchases for me, never a problem with Chinese sellers, not once.

~10 years ago I was importing bulk lots of green laser pointers from Chinese to resell locally. Green lasers were a big novelty back then .

Bank wiring like 4k euro after slowly building trust, never got burned once.

I've ordered TPLINKS and also the minion board build from the TechnoBit website, the orders all look good, my chip transfer was credited as if it were bank wire, all good.

But I have not received any emails, is that unique for me, I wont worry if its the same for everyone?

So the other day I contacted BTC china:


Of course I thought my request was entering "maybe space".

I was suprised and pleased when I got a reply email within 24 hours:


Very nice!

I think chess is one of the few skill games where human players could actually beat the bots.

I do not play chess very well myself, but I have seen youtube vids where good players talk about beating bots using traps etc.

good luck!

Yes that would help a little, any bot would then need a human supervisor standing by to solve captcha.

Also periodic captcha would upset game flow for honest players.

Hi,

It's not open source. The clients is written in ShiVa3D, a multiplatform game engine, which has quite an obscure language and toolset.

Serverside is all PHP, but that's fairly simple, mainly just a daemon harvesting trades from exchanges and VWAPing into 1 minute resolution dbase.

Users will pay a modest subscription fee to use premium features.

There will also be a free version.

I haven't worked out details like pricing and free/premium features yet.

Not if you allow users to play them over the internet, if a human can look at the screen and push a button or two, so can a bot.

Even with locked out hardware/software (which you cant do anyway) it would be possible to make a bot play: bot looks at screen with camera and controls solenoids that push game controls.

Bitcoin attracts hackers, resistance is futile!

Provably fair is not needed on skill games.

In fact provably fair could not be employed for skill games.

Provably fair requires a fully deterministic game.

Provably fair is basically just:

[1]Server decides on heads/tails outcome of coinflip
[2]Server discloses the outcome (encrypted) to user.
[3]User guesses heads or tails.
[4]Server flips the coin for the User.
[5]User wins or loses, and is also told how to decrypt[2] if they want proof of fairness.

With skill, the outcome depends on the users skill, the server has no way of knowing the outcome.

RE: Player vs player skill games,

They would be nice, but remember coders WILL employ bots to play, human players might soon be all saying, "F*CK! Don't play there it's impossible to win"

Yes, player-vs-player skill games where you charge a fee to play are the only path you could take for USA hosted site.

So like 2 player each bet 0.001 BTC, the site take say 1% of that (0.00001 BTC) and then the players slug it out, the winner taking 0.00199 BTC.

I think the whole gamespace would end up being dominated by rainman type people with ungodly game skillz, and of course bots, a few normal folk bumbling through now and then only to be pwned.

Provaby fair need only be employed on luck games.

A skill game does not need provably fair, the player knows if he crashed flappy bird into a wall or not. A player knows if he wins or loses, any disparity in this could not be hidden from the player.

The problem with skill games is as I said, players WOULD employ bots that would fly flappy bird perfectly every time and clean out the sites bank lickety split.

I think that would be classed as a pure game of luck. Each player would place their bet on the wheel, just like in a regular casino where one player can walk up t a wheel and place a bet and then another player can place a bet, and then the wheel is spun. None, one or both players can win/lose against the house.

All pure skill games have exploits... BOTS!

If BTC is available for prize then a coder WILL make a system that:

reads the screen buffer.
performs some process.
synthesizes a keypress.

That would be a last resort attack, easier attacks would be tampering with client side code to always report a win etc.

But say you completely hardened the system it would still be impossible to secure against bot player.

I think user-vs-user skill games are your only option, then of course chess for BTC would turn into users pitting their bots against other users bots, which could be fun in its own right I suppose .

Giving out bitcoin prizes for skill games, how will you stop people coding bots that just win all the time?

Here are some positive thoughts to restoke your optimism:

I think there's alot of room for growth yet, the whole user interface and experience still has a hacky homebrew feel to it, don't get me wrong I love it that way.

But for mass adoption people need chip/pin cards that they can use anyhwere, they dont want to even see a bitcoin address. Just a shiny card with logo on it that "just works" and keeps their savings safe.

Why use chip/pin cards, thats oldshool, why not just employ peoples existing phones (an app) duhh?.. Well employing users hardware introduces a MUCH larger attack surface for hacks. Plus the user psychology, they don't want to worry about the security of their phone, that's just hassle.

Of course the card comes with a paper document to be used in the event of card loss containing information required to recover balance and transfer to new posted out card via online account. Same account can be used for checking balance and maybe even converting fiat to coin.

But then the problem is incorporating this into the current mainstream system, the card readers at checkouts will need to be multi format capable, bank cards and also bitcoin.

Now the solution to this engineering problem is mainly software, a bitcoin card could be made to interface with existing chip/pin card hardware. So... the larger manufacturers of these machines might soon be tempted to make their machines multi-format, it would give them a slight but growing market edge, the cost being only the software dev.

Revenue would be needed
The beast would need food if it were to grow and survive in the mainstream. This could be accomplished in the form of transaction fees, so the miners get fees as they already do (a free market can exist between private miners and the card corp), plus the card corp get a tiny fee also. but no standing charges for the users, except for perhaps new card requests.

Card corps could compete, anyone could start one, free market competition would find a "natural" balance for users and card corps.

Regulation is inevitable
Card users would need verification (binding to card), until we all get chipped it will have to be like opening bank account nowadays, signing in person with photoid etc. most governments would insist on this.

It's coming!
The chance of this happening will increase every day provided bitcoin market cap continues to grow as it is. I think the price is holding well considering bitcoin is still in it's inflationary phase (still being mined).

When things like this start to happen, then crazy growth will begin. You would have to use a log price chart otherwise the growth to date would not show on the graph.

You got me 


Makes sense, last thing you would want as a scam signup would be a quick mind, the slower the better.


I suppose in a way ponzis/hyips are no worse than bitcoin exchanges, for every winner there's more losers (exchange fees), the whole system can disappear at any minute, coins and all (eg mtgox).

Trouble with ponzis though is that they are such a transient thing, the website constructed in an evening, many of them just go quiet and run with coin.

But enjoy your adventures.

Oh my , no it was meant as a sarcastic joke.

I can't imagine anyone reading this as being serious, did you?:


Also, If I were affiliated with this HYIP I wouldn't write this right now:

IT IS NOT WISE TO INVEST IN ANY HYIP, EVER!

edit: again I feel you are not reading all of my posts prioir to replying, you are probably on too much coffee.
