Distributed Ledger Technology or distributed systems are complex computer systems made up of multiple components working together to achieve a common objective. Many people are also confused about blockchain and DLT. Indeed, there are some differences, but these systems rely on a set of fundamental principles that enable them to function properly and effectively. In this blog post, I am going to tell you ten 10 basic principles of distributed systems or DLT.

Basic Principles of Distributed Systems


DLT can handle an increasing number of users and transactions without sacrificing performance. There are different techniques used to achieve scalability, such as load balancing and sharding.

  • Load balancing distributes the load among different servers or nodes to ensure that no single node is overloaded, thus ensuring that the system remains responsive.
  • Sharding involves dividing the system’s data into smaller partitions, allowing for more efficient querying and better resource utilization.

Fault Tolerance

Distributed systems must be fault-tolerant, meaning they can continue to function even if individual components fail. This is achieved through techniques such as redundancy and replication.

  • Redundancy involves having multiple copies of the same data or application running on different nodes.it ensures that if one node fails, the system can continue to function using the other nodes.
  • Replication involves creating multiple copies of the data on different nodes, ensuring that if one copy becomes unavailable, another copy can be used instead.

7 Key Characteristics of Distributed Ledger System


Consistency is essential in distributed systems. It refers to the ability of all nodes in the system to have the same view of the data at any given time. Achieving consistency can be challenging due to the distributed nature of the system. Developers use consensus algorithms and distributed transactions, and many other techniques to ensure consistency in the system.

  • Consensus algorithms are used to ensure that all nodes in the system agree on a single value or decision.
  • Distributed transactions allow multiple nodes to access and modify data simultaneously, ensuring that all nodes have the same view of the data.


Distributed systems must be highly available, meaning they can continue to function even in times of network failures or other disruptions. Achieving availability requires techniques such as replication and fault tolerance.

  • Replication ensures that there are multiple copies of the data or application running on different nodes.
  • Fault tolerance ensures that the system can continue to function even if individual components fail.


Concurrency is a critical principle of distributed systems. It refers to the ability of multiple users to access and modify data simultaneously without causing conflicts. Achieving concurrency requires techniques such as locking and synchronization.

  • Locking allows multiple users to access the same data simultaneously by ensuring that only one user can modify the data at a time.
  • Synchronization ensures that data modifications are made in a controlled and consistent manner.


Transparency is another critical principle of distributed systems. It refers to the ability of users to interact with the system without being aware of its underlying complexity. Achieving transparency requires techniques such as abstraction and encapsulation.

  • Abstraction hides the complexity of the system by presenting a simplified interface to users.
  • Encapsulation hides the internal workings of the system, ensuring that users only interact with the system’s interface.


DLS has the ability to protect data and resources from unauthorized access or modification. Achieving such a high level of security can be tough! However, it is possible through various means; three common techniques are authentication, authorization, and encryption.

  • Authentication ensures that users are who they claim to be.
  • The authorization ensures that users have the appropriate permissions to access data or resources.
  • Encryption ensures that data is protected from unauthorized access by encrypting it before it is transmitted over the network.


Interoperability is a critical principle of distributed systems, referring to the ability of different components or systems to communicate and work together effectively, regardless of their underlying technology or implementation. In other words, it is the ability of different systems to share and exchange data and services seamlessly.

Interoperability is essential in distributed systems because these systems often consist of multiple components, each with its own technology, protocols, and interfaces. Without interoperability, these components may not be able to communicate or work together, leading to inefficiencies and potential failures in the system.

  • To achieve interoperability in distributed systems, various techniques, and standards have been developed. One common approach is to use standardized interfaces and protocols, such as REST or SOAP, that allow components to communicate using a common language.
  • Another approach is to use middleware, such as message queues or service buses, which acts as a mediator between different components, translating messages and data between different formats and protocols.
  • Standardization of data formats and message structures is another technique used to achieve interoperability in distributed systems. For example, the use of XML or JSON as common data formats allows components to exchange data seamlessly, regardless of their underlying implementation.
  • Finally, the use of open standards and APIs is also essential in achieving interoperability in distributed systems. Open standards allow for the development of interoperable systems and applications by providing a common set of rules and guidelines that all developers can follow.


Decentralization is a critical principle of distributed systems. It refers to the ability of the system to function without a central point of control or authority. Achieving decentralization requires techniques such as peer-to-peer networking and distributed consensus.

  • Peer-to-peer networking allows nodes in the system to communicate and exchange data directly with each other without the need for a central server.
  • Distributed consensus algorithms allow nodes to reach an agreement on a decision without the need for a central authority.


Achieving high performance requires techniques such as caching and parallel processing.

  • Caching involves storing frequently accessed data in memory, allowing for faster access and better performance.
  • Parallel processing involves dividing tasks into smaller sub-tasks and processing them simultaneously, allowing for faster results and better resource utilization.
