It is crucial for developers to comprehend the functioning of DLT and its application in various types of blockchains. 

Understanding DLT enables developers to design and implement secure and efficient blockchain systems.


Immutability refers to the property of data in a blockchain that once it is written, cannot be changed. This ensures the integrity and reliability of information stored in the blockchain.


Consensus is the decision-making process in a blockchain network, where all participants agree on the validity of new blocks or changes. Consensus mechanisms ensure the trustworthiness and agreement among network participants.

Crypto Tokens

Crypto tokens are digital assets that represent various utilities or assets on a blockchain. They can be traded and have different use cases, such as cryptocurrencies, loyalty points, or asset ownership.

Smart Contracts

Smart contracts are self-executing contracts with predefined rules encoded in them. They automate and enforce the terms of agreements, eliminating the need for intermediaries and ensuring transparent and secure transactions.


DApps, or decentralized applications, run on a peer-to-peer network instead of relying on a single central authority. They leverage blockchain technology to provide transparency, security, and user control.


Sharding is a technique used to improve the scalability and efficiency of blockchains. It involves splitting the data into smaller parts (shards) and distributing them across multiple nodes, reducing the burden on individual nodes.

Public Blockchain

Public blockchains allow anyone to join, participate, and contribute to the network. They are typically open and transparent, providing accessibility to all participants.

Permissioned Blockchain
