  Casper's proof-of-stake consensus algorithm differs from Ethereum's current proof-of-work algorithm in several ways. Firstly, instead of miners competing to solve complex mathematical puzzles to validate transactions and create new blocks, Casper relies on validators who hold a stake in the cryptocurrency. These validators are chosen based on the amount of cryptocurrency they hold and are willing to 'stake' as collateral. This shift from computational power to stake ownership reduces the energy consumption associated with mining. Additionally, Casper introduces a finality mechanism, where once a block is added to the blockchain, it cannot be reversed, providing more security and preventing double-spending attacks.

  The main difference between Casper's proof-of-stake consensus algorithm and Ethereum's current proof-of-work algorithm is the way in which new blocks are added to the blockchain. In Ethereum's proof-of-work algorithm, miners compete to solve complex mathematical puzzles, and the first miner to solve the puzzle gets to add the next block. However, in Casper's proof-of-stake algorithm, validators are chosen based on the amount of cryptocurrency they hold and are willing to 'stake' as collateral. These validators take turns proposing and validating new blocks, and the weight of their votes is determined by the amount of cryptocurrency they hold. This shift from computational power to stake ownership makes the consensus algorithm more energy-efficient and secure.

  BYDFi, a digital currency exchange, explains that Casper's proof-of-stake consensus algorithm differs from Ethereum's current proof-of-work algorithm in terms of the underlying mechanism for achieving consensus. While Ethereum's proof-of-work algorithm relies on miners solving complex mathematical puzzles, Casper's proof-of-stake algorithm relies on validators who hold a stake in the cryptocurrency. Validators are chosen based on the amount of cryptocurrency they hold and are willing to 'stake' as collateral. This shift to a stake-based consensus algorithm offers several advantages, including reduced energy consumption and increased security. Validators are incentivized to act honestly, as they risk losing their stake if they attempt to manipulate the system.

  Casper's proof-of-stake consensus algorithm differs from Ethereum's current proof-of-work algorithm in terms of the mechanism used to achieve consensus. Instead of relying on miners solving complex mathematical puzzles, Casper uses validators who hold a stake in the cryptocurrency. Validators are selected based on the amount of cryptocurrency they hold and are willing to 'stake' as collateral. This shift to a stake-based consensus algorithm reduces the energy consumption associated with mining and provides a more environmentally friendly approach to securing the network. Additionally, Casper introduces a finality mechanism, ensuring that once a block is added to the blockchain, it cannot be reversed, enhancing the security of the network.
