Ethereum Studio is a platform where the question and answer site for users who mainly Ethereum, the decentralized application platform and smart contract enabled blockchain. Join them; it only takes a minute.

What is Ethereum Studio - Blockchain and how it works? from Blockchain Council

I have seen Ethereum Studio from Ether.camp recommended in various places, but to download it requires some registration, so I assume it is not open source, although it claims to be on the basis of Cloud9. Some people might object to using closed source product for applications that may deal with large sums.

Is it really closed-source? What makes people use it? And being “cloud”, does it require constant internet access, and does it save source files in the cloud?

Cloud9 is not open-source, and the files are stored in their cloud workspace, as well as, you can only download them manually. Both these features, in my opinion, diminish its suitability for smart contract development.

It is an adapted version of the Cloud9 IDE for Ethereum, with some additional tools:

A blockchain emulator called the sandbox, very good for writing automated tests.
Oracle Integration.
It requires internet access since the IDE functionality runs server side on the MS Azure cloud.

WHAT IS ETHEREUM & HOW IT WORKS?

It is an open-source, decentralized network that allows smart contracts to be deployed on a blockchain with the use of ether. It’s a blockchain app (Dapp) platform that uses gas to run - in short. The network was created by Vitalik Buterin in 2015 although the white paper came into existence two years earlier.

That’s a mouthful though! Let’s convert that into plain English by dissecting each word at a time:

WHAT IS ETHEREUM BLOCKCHAIN?

It is a distributed database that is constantly growing and therefore adding a new block to the chain every 17 seconds on average. Each new block contains records such as transactions and contracts.
