Types of Blockchain - JSON

Blockchain is classified into four types based on participant scope and governance: public blockchain (permissionless and decentralized), private blockchain (single-organization controlled), consortium blockchain (jointly operated by multiple organizations), and hybrid blockchain (combining characteristics of both). Each type is utilized for various purposes including cryptocurrencies, internal enterprise operations, inter-industry collaboration, and regulatory compliance, depending on their respective characteristics.
