1. Understanding Permissioned Blockchain

Before diving into the best practices for implementing a permissioned blockchain, it’s essential to understand what sets this technology apart from its public counterpart. A permissioned blockchain, also known as a private blockchain, is a distributed ledger technology (DLT) that operates within a closed network of known participants. Unlike public blockchains such as Bitcoin or Ethereum, permissioned blockchains restrict access to pre-approved entities, offering greater control over who can participate in the network and perform specific actions.

Key characteristics of permissioned blockchains include:

• Limited Access: Only authorized participants can join the network and access its data.
• Controlled Participation: Network administrators can assign specific roles and permissions to participants.
• Enhanced Privacy: Sensitive business information remains confidential within the closed network.
• Improved Performance: With fewer nodes to validate transactions, permissioned blockchains can achieve higher throughput and lower latency.
• Regulatory Compliance: Easier to implement and maintain compliance with industry regulations and data protection laws.
