My favorite part:
Companies, such as banking consortium, R3CEV, that are “playing” in the Microsoft Azure blockchain sandbox are able to build and test products on private versions of the Ethereum blockchain and others where they can learn without the watchful gaze of those able to observe the public transactions. While R3CEV publicized last week that 11 of its bank-members had successfully completed their first work using a private Ethereum blockchain, the company hasn’t yet released exactly which of the current 11 tools in Azure they used.
There are now hundreds of blockchains that have been inspired by the decentralized ledger behind bitcoin, on which a wide range of data can be stored. But the Ethereum blockchain, on which ConsenSys’ tools are built, is one of the most popular. Bitcoin’s market cap is $5.9 billion compared to Ethereum, which is the second-largest, with a $189 million market cap, leaving plenty of room to grow.
