A permissioned blockchain is a type of blockchain network where access to participate in the network and validate transactions is restricted to a specific group of participants. These participants are typically known and trusted entities, such as businesses, organizations, or government agencies. Permissioned blockchains are often used in enterprise settings where privacy, security, and control over the network are important considerations. Participants in a permissioned blockchain must be granted permission to join the network and may have different levels of access and permissions depending on their role within the network.

Definition:
A permissioned blockchain is a distributed ledger technology (DLT) system where access to the network and participation in consensus are restricted to pre-approved entities, known as nodes.
Key Characteristics:
- Permissioned Access: Only authorized nodes are allowed to participate in the network, unlike permissionless blockchains where anyone can join.
- Centralized Control: A governing body or consortium of trusted organizations manages access and permissions.
- Faster Consensus: With a limited number of nodes, consensus is reached faster compared to permissionless blockchains.
- Privacy and Confidentiality: Transactions and data on the blockchain are only accessible to authorized participants, ensuring privacy and confidentiality.
Benefits:
- Enhanced Security: Restricting access limits the risk of malicious actors or unauthorized parties compromising the network.
- Improved Scalability: Fewer nodes reduce network congestion and increase transaction processing speed.
- Regulatory Compliance: Permissioned blockchains can meet industry regulations that require data privacy and controlled access.
- Efficient Governance: A governing body can manage network upgrades, dispute resolutions, and ensure compliance.
Use Cases:
- Supply Chain Management: Tracking goods and materials across the supply chain while maintaining data privacy and security.
- Financial Services: Facilitating transactions, cross-border payments, and asset management in a controlled environment.
- Healthcare: Sharing patient data securely among authorized healthcare providers and researchers.
- Government: Recording and tracking sensitive information, such as citizen records or land registry data.
- Trade Finance: Streamlining trade processes, reducing paperwork, and ensuring trust among trading partners.
Limitations:
- Limited Participation: Restricting access can limit the potential for innovation and adoption.
- Centralization Concerns: The governing body may have too much control over the network, raising concerns about centralization.
- Trust in Participants: It is crucial to ensure trust among authorized nodes to maintain the integrity of the blockchain.
