Who are the top 5 rival Blockchains?

Each of these blockchains is different in terms of its architecture, consensus mechanism, use cases, and target audience. For example, Bitcoin and Ethereum have different approaches to scalability and security, and Binance Coin and Tether have different utility cases as compared to Bitcoin and Ethereum. Similarly, Cardano differentiates itself with its proof-of-stake consensus mechanism and focus on sustainability.
