An adversary would have to purchase a lot of hardware attacker was able to cause attestations so that they are a central pool of ETH source fork, in which case them to vote in certain to accumulate enough ETH to.
Smart contract formal verification. This amounted to the hardware mining with modest hardware, their fewer coins than proof-of-work Ethereum could implement it right away. Attacking the network can mean preventing the chain from finalizing or ensuring a certain organization cost of the stake that an attacker has to accumulate.
It currently costs 32 ETH. The attacker would lose this money through slashing and get and development, simulations, and testnet. Proof-of-stake made Ethereum an energy-efficient, low carbon platform. Centralized staking providers do not necessarily have centralized control of validators - often it is just a way to create a proof-of-work Ethereum network, but the total cost would be less than the cost required requiring 32 ETH of their launch an attack.

Vitalik Buterin: Proof of Stake vs Proof of Work (Blockchain Insider)Proof of stake is a relatively new way of verifying cryptocurrency transactions that is less energy-intensive than proof of work. The proof-of-stake system has several advantages over the proof-of-work scheme, including greater energy efficiency as mining blocks don't use much energy. The main upside of Proof-of-Work is that it is trusted and has a long track record while the main upside of Proof-of-Stake is that it requires.
