A permissioned ledger can be defined as a type of blockchain network with limited participants. Unlike public (permissionless) ledgers, where anyone can join, only a restricted group with controlled access can join. 

Participants require authorization to join. This type of setup promotes privacy as well as confidentiality. In contrast, public ledgers allow unrestricted access and participation, promoting decentralization and transparency. Permissioned ledgers cater to industries needing controlled collaboration among known entities, while general ledgers emphasize openness and inclusivity, with transactions validated by a decentralized network of participants.


Critical features of permissioned ledgers are:

  • Controlled Participation
  • Identity management for authentication leads to a secure network
  • Decision-making gets fast by the use of the consensus mechanism
  • Selective data sharing is done to enhance security with restricted access in permissioned ledgers.
  • Balanced decentralization is done by only including trusted participants and tailoring governance.
  • This approach makes them ideal for scenarios requiring collaboration, privacy, and compliance among a specific group of entities. 


Access control in permissioned ledgers is essential for maintaining not only privacy but also the security of the participants. It ensures that only authorized participants can access and interact with the ledger, which helps in protecting sensitive information.

Whereas the Governance model in permissioned ledgers defines how decisions and rules are made and disputes are resolved among the members sharing the permissioned blockchain. These models establish a framework for ensuring participants’ roles, responsibilities, and interests are aligned, which leads to a mechanism that adapts to the changing needs and wants of the participants over time.


As permissioned ledgers are famous for their controlled collaboration, security, and privacy features, trusted entities must cooperate, share information, and maintain the agreement while tailoring the network. They are widely used, and many use cases can be found.

  • Real Estate Domains
    • It offers a secure and unalterable record of property ownership and title transfers, making it easier to confirm requests, decrease fraud, and simplify property transactions.
    • The job of a notary is done by blockchain, which includes records of the buying or selling of each estate. Additionally, it can be used to track the history of a property.
  • Finance
    • The approach towards secure and fast transactions is extensively promoted.
    • Investors and traders are safe and sound while using intelligent contracts or making a transaction.
    • Cryptographic hashing prevents altering any data inside the blockchain, which makes the data secure.
  • Hospital Management Systems
    • The records of the patients are stored in the hospital management network in a permissioned blockchain, making it easier for doctors and patients to access and locate them in the future.


Permissioned ledgers offer

  • Enhanced data privacy
  • Controlled collaboration
  • Tailored governance
  •  Secure transactions
  • Data Sharing

However, implementing permissioned ledgers requires careful planning to ensure participant trust, reduce interoperability issues, and manage network scalability. 


Challenges faced by permissioned ledgers can be establishing consensus protocols and finding the balance as we tailor the permissioned ledger network to meet the needs of the participants while following the basic standardized rules.

We can overcome these difficulties by choosing the correct preferences, like

  • Selecting appropriate technology
  • Making discipline for governance rules
  • Promoting collaboration among the participants


  • Permissioned ledgers offer controlled access, privacy, and tailored governance in blockchain networks. 
  • They ensure secure collaboration and a balance between customization and standardization, which means the permissioned ledgers make entities work together, leading to data integrity while maintaining agreement with industry regulations.
  • Permissioned ledgers restrict access to trusted participants, making them tailored for private collaboration. Public blockchains are open to anyone, enabling decentralized applications like cryptocurrencies. 
  • Permissioned ledgers prioritize controlled access and tailored governance, whereas public blockchains emphasize openness and decentralization. Everyone shares this type of decentralized network, and the data isn’t counted only on one prime authority.
