Yes, Casper FFG will be implemented in Eth2 phase 0. Most Eth2 client teams have already implemented the Eth2 variant of FFG and all public Eth2 testnets are using it. Some recent information about Eth2 and FFG can be found in Combining GHOST and Casper. There is a long-term plan to switch to Casper CBC, however serious specification or engineering works ...

Metropolis is not a fork but a milestone in the Ethereum roadmap. Simplified: Proof of Concept 1-8 (ETH 0.1) were several implementations of the Ethereum protocol in 2014 and 2015. Olympic (ETH 0.9) was the last proof-of-concept testnet for Ethereum prior to the mainnet launch (2015). Frontier (ETH 1.0) was the beta phase and the launch of the Ethereum ...

The above answers contain good arguments about the drawback of PoW scalability: PoW schemes require propagating new candidate blocks to all miners around the world, and occasionally miners will split and do work on a chain that ends up being orphaned / not the longest. This happens for brief moments all the time, and in Ethereum these "almost blocks" help ...

There are many steps in the transition that are not ironed out yet. However, there are some information available that are certainly accurate for the upcoming phases of ETH 2.0. Staking You can transition to the Beacon Chain which is Phase 0 (see this answer for all milestones). In that step there will be a deposit contract deployed on the legacy ETH 1.x ...

EV means expected value. It is the average you will receive if you repeat the experiment a large number of times. p=0.9 means if you choose that branch you have 90% probability of it being the correct one. The locking happens when you "vote". You can vote both alternatives. They analyze that case and propose possible solutions to prevent that behavior.

It's true that PoS could lead to centralization and in a way encourages centralization - being a technical improvement over PoW in the context of energy use - PoS nodes run the same software with the same energy requirements regardless of the number of coins staked. I would like to point out firstly that blockchain attempted to take a centralized world and ...
