Comparison between Blockchain 1.0, 2.0, and 3.0.


This article will compare the three generations of blockchain technology: Blockchain 1.0, 2.0 and 3.0. We will try to understand each of the versions in-depth so that you can understand why businesses and individuals are increasingly turning towards the latest version for their technological needs.

Blockchain 1.0:

The first generation of blockchain technology is called Blockchain 1.0 or simply “blockchain”. Satoshi Nakamoto created this generation in 2009, with Bitcoin being its first application and was designed for tracking financial transactions only, such as transferring value from one party to another in a secure, immutable ledger format without the need for third-party intermediaries like banks or governments. The features that make this blockchain version unique are its decentralized architecture, cryptographic security, and ability to facilitate peer-to-peer transactions.

Blockchain 2.0:

The second generation of blockchain technology is often referred to as Blockchain 2.0 or “smart contracts”. This version was created in 2015 by Ethereum’s Vitalik Buterin to extend the functionality of blockchain beyond just financial transactions. The main difference between this and other versions is that it enables developers to create autonomous “smart” contracts that can store data on a distributed ledger without relying on third parties for enforcement. These contracts can be self-enforcing, reducing the need for costly dispute resolution processes such as those offered by courts and arbitration services.


Blockchain 3.0:

The third generation of blockchain technology is often referred to as Blockchain 3.0 or “distributed ledger technology (DLT)”. This version was created in 2016 and has been continuously improved upon, allowing it to become the most advanced form of blockchain available today. The main features of this version are its scalability with faster transaction speeds, improved privacy with enhanced security protocols, and greater flexibility with the addition of new programming languages such as Solidity and Vyper for developers to create smart contracts on the blockchain. It also allows for interoperability across multiple blockchains so that users can easily access services or assets from different networks without going through a third-party intermediary. This version of the blockchain is now being used in various industries and applications such as voting, healthcare, supply chain management, and more.



While all three versions of blockchain are based on the same underlying principle – decentralization – they differ in functionality and use cases.

Blockchain 1.0 is primarily used for cryptocurrency transactions, while Blockchain 2.0 allows for developing decentralized applications (dApps). Blockchain 3.0, on the other hand, is still in the early stages of development, and its use cases have not been fully realized.

A key difference between the three versions of blockchain is the speed and scalability. Blockchain 1.0 is relatively slow, as it can only process a limited number of transactions per second. Blockchain 2.0 is much faster due to its smart contract capabilities, while Blockchain 3.0 promises even greater speeds since it uses sharding. This technique divides data into small pieces and distributes them across multiple computers.

Another major difference is the cost of transactions. Blockchain 1.0 and 2.0 are relatively expensive since they rely on miners to validate transactions, while Blockchain 3.0 is much more cost-efficient due to its proof of stake consensus algorithm, which does not require miners.

Overall, each blockchain version has unique features and use cases, making them suitable for different types of applications. As technology advances and new versions of blockchain emerge, developers will have even more options when choosing a platform for their projects.

The main takeaway from this comparison is that there is no one-size-fits-all solution to building decentralized applications or conducting secure online transactions; each project should carefully consider all available options and choose the best one for their specific needs.



In conclusion, blockchain technology has evolved significantly over the past decade. Blockchain 1.0, 2.0, and 3.0 each have unique features and use cases, making them ideal for different projects. Ultimately, it is up to developers to decide which version of blockchain suits their project’s needs best – understanding the differences between these versions can make this decision much easier.
