On Tuesday, Danny Ryan, the developer of Casper the Friendly Finality Gadget (FFG), published a Casper v0.1 "First Release" of the code GitHub, admitting that "v0.1.0 marks us clearly tagging releases to help clients and outside auditors more easily track the changes and contract"
He gave comments to some Reddit article regarding the update, stating:
Casper FFG was initially published in October 2017, aiming to resolve "open concerns of economic finality via validator deposits and crypto-economic incentives." In late April the Ethereum Improvement Proposal (EIP) Number1011: Hybrid Casper FFG has been introduced, with the goal of creating a hybrid system of consensus that attempts to push the network from issues associated with cryptocurrency exploration.
The Hybrid Casper FFG will reportedly combine Proof-of-Work with Proof-of-Stake (PoS) consensus, with the goal of eventually switching to PoS. As stated by the EIP, among the specifications of the upgrade reduces the block payoff for miners to 0.6 ETH from the current 3 ETH.
