Jameson Lopp, a Bitcoin enthusiast, and a successful entrepreneur, gave his views on the discussion underway between Vitalik Buterin and Vlad Zamfir about the implementation of the Casper model of Proof-of-Stake [PoS] on the Ethereum blockchain. He addressed the state of Ethereum and whether or not developers would do a good job transitioning to PoS.
Ethereum and most cryptocurrencies are usually constructed on top of the Proof-of-Work [PoW] concept to validate and add blocks to the blockchain. The major drawback when it comes to PoW is that it requires a lot of resources. Apart from that, it can be also corrupted by the malicious 51% attack.
