Bitcoin Forum

At the Bitcoin Miami (http://btcmiami.com/) conference Bitcoin developers(TheBlueMatt, Luke-Jr, and Super3) and members of the community discussed very important issues. Out of those discussed we generated a concept of Pizzacoin with the with Innovative Proof-of-Pizza. It is extremely ASIC resistant, and allows merged cooking in the same oven. There is absolutely no pre-mine. Might be a little pre-baked...

What is Pizzacoin?
Listen to our discussion about Pizzacoin on Soundcloud (https://soundcloud.com/shawn-wilkinson-2/proof-of-pizza-talk).

How do I get Pizzacoin?
Pizzacoin is a community funded effort. The genesis pizza's address is 1pieg46FSLknCyfnvW6mLLavV8hShV9BW. Funds "expenses," food for developers, and pizza blocks. Current price per pizza for the IPO is as follows.
Day 1 - 1 BTC = 1 Pie
Day 2 - 1 BTC = 1/2 Pie
Day 3 - 1 BTC = 1/4 Pie
etc... With pizza reward for the funding period halving everyday.

When will Pizzacoin be released?
We estimate development time will be 2 weeks^tm.

More Info
Pizzacoin Whitepaper: Joe White is working on the whitepaper.
Pizzacoin Sourecode and Binaries: 2 weeks^tm.
Total Supply: Unlimited
Block Time: Delivery time

Genesis Pizza
The genesis pizza was baked at the Bitcoin Miami conference. Here is a picture of the genesis pizza with TheBlueMatt. Sauceshi Pizzamoto might or might not be among us.

Genesis Pizza Details
Creation Date: 1/26/2014 13:39:20
Delivery Address: N/A
Bitcoin Address: 1pieg46FSLknCyfnvW6mLLavV8hShV9BW
Merkle Root: 624acdce1fff7e374739ff0413162acffff45cc3339d9801c12a62cf67715966
Hash: 624acdce1fff7e374739ff0413162acffff45cc3339d9801c12a62cf67715966

How to Bake
1. Order pizza
2. Take a picture of your pizza, with time stamped note
3. Find the sha256 hash of your picture using Hashslash (http://xylemstudios.com/products/download.php?id=hashslash)
4. This becomes your "merkle root"
5. Append your merkle root to end of the previous block hash to find your block hash.
6. Post your block details here.
7. ???
8. Pizza > Profit

haha, I'm excited.

does pizzacoin offer freebies if its not delivered hot within 15 minutes?

Yes if your transaction is not confirmed in 15 minutes your transaction fees are free.

Will it be Buffet style too?

Can't wait to see pastacoin.

RFC 1149 would enjoy delivering this I'm sure :)

If we have learned anything from the recent alt-coin explosion it's that we don't have to do it first to be the best.

I'm working on the whitepaper and have given some access to a few of the other members to view my progress.

I currently am working to build up my sha256 mining farm a bit but I expect that I should be able to have a white paper released within two more weeks.

After that I hope to build up my pizzeria and bakery rapidly

just remember pizza regulators: you will never be a part of this.

I am glad to have met with these awesome devs to be able to express my exciting new proof-of concept and I feel that it can go a long way to helping end world hunger and to help ease all those late night cravings that developers like ourselves face every day.

I personally am extremely excited for ice cream a la mode.

I will be working on the pizza ring today and hope to have pie #1 ordered this afternoon. There's just too many toppings and so little time, I can not decide!

Excellent.

Watching and waiting should be a great coin.

The chain is hashing right now :)

Tonight on the net ;)

Hopefully we can get a few developers to give us some more novel ways to create our pie ring (block chain) and allow it to remain decentralized. As you know it is getting harder and harder for individual pizzerias to compete with national chains like dominoes, pizza hut, and the likes.

I expect we will see a huge spike in munching power in america (and around the world) during the upcoming superbowl. I am factoring these seasonal spikes in to the difficulty algo so that higher quality ingredients are required during these spikes with a rapid recalculation and decline in difficulty once these events are over.

I am in

For that one

Great to hear!

Hopefully once I have the whitepaper finished you will be able to join the pie ring quickly

SCAM! ketchup instead tomatoes!  :D

Eventually we will hardfork to allow you to choose the sauce as well, but i think to start tomato is easier to prove than ketchup. Although I'm open to suggestions and the protocol is based on general consensus of how the word "pizza" is defined

I like Hearty Marinara Sauce.

+1

 :D

Here's a few sentence appetizer of the white paper abstract for anyone interested.

"
A purely peer-to-peer version of electronic pizza delivery would allow late night hunger to be satisfied directly online from one party to another without going through an established pizza institution. Pizza toppings provide part of the satisfaction, but the main benefits are lost if a trusted pizzeria is still required to prevent the double-eating problem using a peer-to-peer network. The network timestamps delivery by hashing a photo of each pizza into an ongoing ring of hash-based, photo enforced, proof-of-pizza, forming a record of all pizzas known to have been delivered so that a record cannot be changed without re-baking the pizza.
"

My favorite is "Proof of Steak". 

We must merge mine this somehow into this new algo but I don't know how to solve the issue with all the mad cows.

Excellent lunch Guys!  Was glad to be a part of that.

I've been a bit side tracked with the bakery asking for cannoli and had to push the proof-of-pizza white paper release back a week. But be assured we will make sure to have it released in two more weeks ;)

Why pie?

pie not? :D It's called a pizza pie after all  :)

coin name is already taken or ? https://bitcointalk.org/index.php?topic=431508.0

That's just a fraudulent scamcoin. There's no pizza used in it at all!  ;)

+1  :D

I am sorry that the whitepaper is not released yet, i am working out the details to help you know if the ingredients in the pie before yours were GMO or not. This is proving to be a bit of a challenge but i think I might have had a breakthrough tonight.

This is starting to get ridiculous. :)

Wow really? These coins lately seems like a joke.  ::)

It appears as if a double spend attack is not entirely undesirable.

You're supposed to clone the toppings before they get on the pizza.

Hey I found a vulnerability. If a cat is left near the pizza then a pie can't be spent/eaten anymore, unless the user is disgusting.

Reference:

Hm, true. But at least then you have a cat to butcher.

That's a great point, BUT the fact still remains that there are more honest cats than dishonest cats. Plus, we may want to consider Proof of Pizza as a possible way to test sentient intelligence (if a cat can take it's own photo with a photo of the last pizza that was added to the pie, we should give it credit).

We can call those orphaned pizzas :D

We also must assume that anyone who is using the Proof-of-Pizza algo will be conscious enough to provide ample anti-cat measures. Such measures include field mice, mouse traps, and dogs.

"But dogs will eat your pizza even faster!" you say. Well, maybe maybe not. Dogs can be leashed and thus avoiding the age old delemia

This brings the buttered cat paradox to mind.

We need to seriously consider the innovative design behind PoP being the fact that it can be insta-mined and it *IS* the first known working method to feed a developer (proof of development PoD) and will keep their bellies full. It allows anyone to participate, and is ALREADY smart AND dumb phone compatible, anyone wiht a camera can do it or even anyone with the ability to draw a circle depicting their pizza (assuming they provide valid proof of purchase/proof of partaking in a meal), and actually I think we could even say XKCD could get in on the pizza hashing action with their creative depiction of their developers eating pizza.

But also,this brings up a more valid point. I need to finish that white paper. It's actually sitting half complete somewhere.


hahahahaa. this came to mind instantly

Luke-Jr ,how many old accounts do you have?

im not luke

Was this ever released?

I think I am going to order a domino pizza after reading this. So what's so unique about this ICO?. Everyone is just starting an ICO these days. The only good ICO's now are Blocklancer and MASS.Cloud

dev ... How much total supply coin ?

Sorry, I ate it before it was released. Delicious, though...
