Casper is the first live proof-of-stake (PoS) blockchain based on the Casper CBC standard, which became live on mainnet on March 30, 2021. The Casper platform aims to accelerate the worldwide adoption of blockchain technology, smart contracts, and decentralized applications (DApps).Casper is a one-of-a-kind blockchain project that uses the proof-of-stake (PoS) consensus technique. The network is incredibly adaptable in terms of use cases due to its entirely decentralized design. Casper also has a future-proof design, with upgradeable smart contracts and predictable transaction gas costs. Casper also introduces a new benchmark for blockchain energy usage that is 136,000% more energy-efficient than Bitcoin.
