    Casper's proof-of-stake consensus algorithm differs from traditional proof-of-work in several ways. Firstly, instead of miners competing to solve complex mathematical puzzles, Casper relies on validators who hold a stake in the network. These validators are chosen to create new blocks based on the amount of cryptocurrency they hold and are willing to 'stake' as collateral. This shift from computational power to ownership of cryptocurrency makes Casper more energy-efficient and less susceptible to 51% attacks. Additionally, Casper introduces a finality mechanism, which means that once a block is added to the blockchain, it is considered final and cannot be reversed. This provides greater security and reduces the risk of chain reorganizations. Overall, Casper's proof-of-stake consensus algorithm offers a more sustainable and secure approach to validating transactions compared to traditional proof-of-work systems.

    The main difference between Casper's proof-of-stake consensus algorithm and traditional proof-of-work is the way in which new blocks are added to the blockchain. In proof-of-work, miners compete to solve complex mathematical puzzles, and the first miner to solve the puzzle gets to add the next block. This process requires a significant amount of computational power and energy consumption. On the other hand, Casper's proof-of-stake algorithm selects validators based on the amount of cryptocurrency they hold and are willing to 'stake' as collateral. These validators are responsible for creating new blocks. This shift from computational power to ownership of cryptocurrency makes Casper more energy-efficient and environmentally friendly. Additionally, Casper introduces a finality mechanism, which ensures that once a block is added to the blockchain, it cannot be reversed. This provides greater security and reduces the risk of double-spending attacks. Overall, Casper's proof-of-stake consensus algorithm offers a more sustainable and secure approach to validating transactions.
