HBC Blockchain 101 – Part 3: Permissionless Blockchains

Understanding Permissioned vs. Permissionless Blockchains

In his insightful video series, Dr. Keir Finlow-Bates explores the various ways to customize a blockchain network. This third installment delves into the critical distinctions between open vs. private and permissioned vs. permissionless blockchains, highlighting their unique applications and benefits.

Open vs. Private Blockchains

• Private Blockchains: These networks operate within a closed environment, with access granted only to select, authorized participants. They are often used within organizations or consortia where a degree of control is necessary.
• Open (Public) Blockchains: True to their name, these blockchains are accessible to anyone wishing to join. They promote transparency and decentralization, with examples like Bitcoin and Ethereum leading the way.

Permissioned vs. Permissionless Blockchains

• Permissioned Blockchains: To participate in these networks, users must first obtain approval from a governing authority. This allows for greater regulation and oversight.
• Permissionless Blockchains: These decentralized systems embrace openness. Anyone can join, contribute, and validate transactions, fostering a trustless environment where no single entity holds absolute power.

Choosing the Right Configuration: Use Cases

The optimal blockchain setup hinges on your specific goals:

• Private Permissioned Blockchains: Well-suited for streamlining processes and improving efficiency within a network of trusted partners, such as supply chain management or internal record-keeping.
• Public Permissionless Blockchains: Empower projects that prioritize decentralization, censorship resistance, and transparency. Prime examples include cryptocurrencies and open-source platforms.
