DODO_FRAG_Cardano ADA-4.0 (CARDANO ADA-4.0)

Cardano is a third-generation, decentralized proof-of-stake (PoS) blockchain platform designed to be a more efficient alternative to proof-of-work (PoW) networks. Scalability, interoperability, and sustainability on PoW networks like Ethereum are limited by the infrastructure burden of growing costs, energy use, and slow transaction times.
