your biggest problem with p2p poker is not the shared pot but to deal unique cards without central authority.

this can be solved by dealing not unique cards and cancelling the game if the same card appears twice e.g. on showdown.

but it is not texas holdem any more.

I'd say, don't wait for altcoins, we can use bitcoin testnet and trade them for real bitcoin, or testnet for testnet coins.
Assuming bitcoin has this feature.

Perhaps test the exchange by trading bitcoins for bitcoins?

Satoshi never admitted the truth, he is angry.

His main wish was that the hashing power shall stay decentralized, in order to generate the longest chain and outpace attackers.

Now I ask: Who of you is mining Bitcoin?

.. silence....

I ask again: Who here is solo mining? On their own machine. On their own property. You have no excuse. Attaching wire to wire is not stealing according to the scriptures.

To all the nonbelievers, screaming "But I'll never hit a hash".

Why are you asking Who is Satoshi? Satoshi Nakamoto is the voice of one calling: “In the internet Prepare the connectivity for the LORD, make straight the route. Let every BSS be lifted up, And every router and switch be made low. Then the glory of the LORD shall be revealed,
and all peers shall use it together; for the code of the LORD has compiled.

I have earned equivalent of 30 $ in fiat today.

listen up mate you say I want texas holdem blablabla

you dont really know what you even want. so you need:

1. software analysts to figure out what is and is NOT to be done.
1.1. First of all the rules of the game has to be settled. Texas holdem has many variants fixed/no limit/tourney/sattelite whatever, also details like do the players change seats, do they reseated when fold, etc.
1.1.1 game guarantees like how you guarantee server latency and ddos resistance
1.2.If you want multiple variants or full casino, which games and which not. Make the software DIFFICULT TO ADD future additions makes the project significantly cheaper & faster & easier to develop.
1.3. Details of the infrastructure. Where is served public cloud/private servers etc. How will you guarantee users don't see each other cards. How will you guarantee the cards are dealed randomly. What to do in case it fails etc.
1.4. Details of the payment system & its security. What to do in case of breaches.

2. implement the servers software. start with login/auth/payments deposits,withdrawal. next comes the management of game sessions/rooms/turneys/whatever./next the dealing of cards/logging them to a safe place/doing the actual game actions fold/check/raise/computing the winning card/logging/making the desired accounting changes based on the outcome/game quit

3. now come the time for the sugar. you hire artists to make a cool gui in flash/html5 whatever. you add crap features like avatars and whatnot.

4. testing. you hire or rent someone who can test an application. after many weeks adjusting 2. and 3. you maybe get a working application.
5. hire an engineers who review your infrastructure and determine what needs to be reworked in other to guarantee latency / availabiliry. skip this and turn of users playing for $10000 expires yet have fun explaining them on tech support they didn't BET and their pcs are bad when in fact your game is laggy. Also have fun when somebody DDOS your casino and it vanishes from the internet during an important truney finals.
6.after several months you MAYBE have a secure application. or not and user's (in fact YOURS) coins simply vanish. oops. wait i know the answer: YOU steal them earlier than they

welcome to the world of software developement .

I like the idea of electrophoretic display. I suggest such device be separate from the physical coin, because it's reusable.
Such display can be used for 1. display vanity address; 2. display the full transaction the coin will sign.

This picture is a diagram of the 4 states of a "smart physical bit coin" in order.

http://imgh.us/physical_bitcoin.svg

Physical bitcoin with chip inside can work as follows:

at home

1. Smart coin would be produced in perpetual RNG seeding state.
2. After that the user shall choose his vanity address prefix/postfix (to prevent producer hardcoding private key)
3. The coin receives vanity prefix and start bruteforcing address.
4. Coin now in propagating pubkey state while keeping the private key secret.
5. User check the pubkey has vanity prefix and top ups his coin.

secure payment

5. The POS terminal sends the transaction to physical bitcoin.
6. Physical bitcoin atomically signs the transaction and destroys the private key (can destroy the signing circuit & priv/pubkey memory ).
7. Coin now in perpetually propagating txsig state with all non needed circuits destroyed.
8. Tx sig is sent to POS. TX Sent to bitcoin network. The clerk gives the goods to customer.

Opinions?

It may or may not be written by Derek or whoever that is.

what frontend? html5? flash? etc..

1. running BTC node
2. keeping full blockchain backup
3. Interested about physical Bitcoin projects and POS systems

Hi I'm designing a custom crypto currency Now I'm simulating the mining. The block time will be 20 seconds

The idea is simple. A game that's also a bitcoin wallet.

Opinions?

will there be a DIY version of this physical bitcoin?
perhaps construction like https://github.com/platecoin/platecoin?

the maker's private key sticker can be sticked on side A, while the clerk generates key B in shop and puts
it to the rectangular window near buyer, charge it and show him the transaction in blockchain.

buyer only need to trust maker sticker.

opinios?

I join a team

Hi. What about the situation when miner create cheaper order and give to orderer for original price, claiming profit??

Hi do you think a raspberry-pi coffee machine can be possible?

Perhaps using this token??? https://github.com/platecoin/platecoin/

please also backup the wallet.dat
