Ethereum Foundation Releases Alpha Casper Proof of Stake Testnet
I&#x27;ve been trying to understand why PoS is an improvement over PoW. To me PoS seems like a weaker requirement on network control than PoW. Since PoW requires possession of actual physical hardware and electricity it should be more difficult to obtain than a virtual currency. To me moving from PoW to PoS is analogous to moving off of the gold standard and placing trust in the value of the currency with whomever possesses it.
