Overview

Types of Blockchain

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.

2	private-blockchain	Private Blockchain	A permissioned blockchain managed by a single organization.	Permissioned (single organization)	["Hyperledger Fabric","Quorum","R3 Corda（プライベート用途）"]	Centralized	High	Limited (internal only)
3	consortium-blockchain	Consortium Blockchain	An intermediate blockchain jointly managed by multiple organizations.	Permissioned (multiple organizations)	["R3 Corda","Hyperledger Fabric","Quorum","Energy Web Foundation"]	Semi-decentralized (consensus-based)	Moderate to high	Public among participants
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
