You’re probably heard of Blockchain by now – the relativity new technology underpinning a whole host of cryptocurrencies and distributed apps, promising exciting solutions across a range of markets, from IoT and machine to machine communication and healthcare, to identity management, supply chain and more.
But, have you got to grips with how they work? How you use them? What they can do? How you code apps on them?
Intended as a foundation for developing applications or solutions with a modular architecture, Hyperledger Fabric allows components, such as consensus and membership services, to be plug-and-play.
HyperLedger Fabric leverages container technology to host smart contracts called “chaincode” that comprise the application logic of the system.
As part of the Sandbox, we’ll provide you with an Ubuntu VM that has four docker containers containing the peers of the blockchain, split across two separate organisations. Each one of these peers is capable of hosting your chaincode that can be used to execute code on Fabric that support well, any app or logic that you wish!
Of course, feel free to re-configure the peers and organisations as you wish, along with build more channels to communicate on (hit the Hyperledger Fabric link earlier to learn more about these concepts or fire directly over here).
We also provide you with a short example of how to transact on the blockchain and move some value across peers taking part in the chain, to get you started, should you need.
There’s also the CLI that you can use should you wish to explore this method of interaction further.
Note that we're using LevelDB as the data store on our deployment of HyperLedger fabric. It's a light-weight, single-purpose library for persistence with bindings to many platforms, including Fabric.
As always, let us know what you think of the Sandbox and provide us any feedback through the Sandbox forums. Cisco are a premier member of the HyperLedger effort, so we’d love to know what you think!

I'm trying to complete the lab in the title. One section has you export the code in python. I can't get the code to run because it is dependent on a "requests" library. Where do you get this library? I attempted to download it: $ git clone https://gi...
