Why the Ether Pool?
Each Environment gets access to an Ether Pool with 1 billion Ether (ETH). This Ether is specific to an environment and cannot be transferred outside of the environment. In a permissioned blockchain implementation (i.e. Kaleido), Ether is not necessary for sending transactions, deploying smart contracts, etc. as the gas price is set to 0. However, some use cases may desire the use of Ether. For example, Ether could be used to prioritize transaction mining or enforce smart contract costs.
