Hyperledger projects
As mentioned, a hyperledger isn't a single blockchain technology, but rather a collection of technologies donated by member companies. While there is a long-term goal of greater integration between projects, currently most of the Hyperledger projects function independently. Each project's core code base was donated by one or more of the Hyperledger member organizations, based on problems they were trying to solve internally before open sourcing the code and handing ownership to the Linux Foundation.
Hyperledger Burrow
Hyperledger Burrow is a re-implementation of the Ethereum Virtual Machine (EVM) and blockchain technology, but with a few key changes. First, instead of using the proof-of-work consensus algorithm used by the public Ethereum chain, Burrow is designed around the Tendermint consensus algorithm (See Chapter 7, Achieving Consensus). This means there are no miners and no mining to be done on Burrow-based projects.
Second, Hyperledger Burrow is permissioned—the...
