Episode 3: Common rules
Defining protocols

Can you imagine a company without a boss? An online payment without a payment provider? A bar without a bar owner? How could this possibly work? Let’s find out!
As you know: Our friends decided to run the bar together. But of course, everybody has different ideas on how to manage the business. Oscar wants to drink for free (of course), and Alice wants to introduce her favourite craft beer.
So they agree to write down some common rules. After a lot of debate and voting rounds they have created a protocol which exactly describes how to order a drink, how to write down who drank what, how to pay, when to open and close the bar and a lot more details. Everybody signs the protocol (even Oscar) and promises to stick to it.
The core element of all blockchains is their protocol. All computers on a peer-to-peer network run the same protocol, which manages their behaviour and communication. For example, the Bitcoin protocol specifies exactly how transactions are structured and stored on the Bitcoin blockchain.
What are the elements for the Blockchain Bar’s protocol. Find out in the following episodes …
But maybe you first want to learn some more about blockchain protocols on TheBlockchainBar.com.

The story of Blockruption’s Blockchain Bar began in June 2018, when Martin Breitsprecher and Collin Müller sat in a restaurant in the port of Hamburg. For a long time, they had been trying several approaches of explaining the blockchain to non-nerds. While joking around, they discovered that almost any blockchain concept can be explained with a hypothetical bar that is run by the guests themselves in a beer-to-beer … uh … peer-to-peer fashion.
