Types of Blockchain - Markdown
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.

| 4 | hybrid-blockchain | Hybrid Blockchain | A blockchain combining characteristics of both public and private types. | Selective (flexible based on use case) | ["Symbol (XYM)","Dragonchain","Ripple","IBM Food Trust"] | Flexible (organization-controlled with public auditability) | Moderate to high | Selective disclosure |
