Introduction to Blockchain

The world is changing at a dizzying pace. The explosion of the Internet and digital technology has created breakthroughs in all aspects of life. In this context, Blockchain has emerged as a breakthrough technology, opening the door to a new era of transparency, security, and efficiency.

Blockchain is a technology for storing and transmitting information in a secure, transparent, and immutable way. Each block contains a certain amount of information and is linked to others using cryptography, forming a seamless chain of data.

The development of Blockchain can be divided into main stages:

• Blockchain 1.0: The initial stage, typically represented by Bitcoin, focused on creating cryptocurrencies and conducting peer-to-peer financial transactions.
• Blockchain 2.0: The stage of developing smart contracts, allowing for the automation of agreements and transactions without the need for third-party intervention. Ethereum is a prime example of this stage.
• Blockchain 3.0: The stage of applying Blockchain to various fields beyond finance, such as supply chains, healthcare, and elections.

However, previous Blockchain versions still have limitations in processing speed, scalability, and transaction costs. To address these issues, Blockchain 4.0 technology was born, marking a new step forward in the digital technology revolution.

Comparing Blockchain 4.0 with previous versions

To better understand the breakthrough of Blockchain 4.0, let’s compare it in detail with its predecessors:

Processing speed

• Blockchain 1.0 (Bitcoin): Relatively slow transaction processing speed, only about 7 transactions per second. This causes network congestion and high transaction fees when the network is overloaded.
• Blockchain 2.0 (Ethereum): Improved speed, around 15-20 transactions per second. However, it is still not enough to meet the needs of complex applications and the increasing number of users.
• Blockchain 3.0 (e.g., EOS, Cardano): Processing speed continues to be enhanced, reaching hundreds to thousands of transactions per second thanks to new technologies like Delegated Proof-of-Stake (DPoS).
• Blockchain 4.0: Achieves a breakthrough with processing speeds of thousands, even millions of transactions per second by applying advanced technologies like sharding, DAG, and improved Proof-of-Stake (PoS). This opens up the possibility of applying Blockchain in fields requiring high processing speeds such as real-time payments and the Internet of Things (IoT).

Scalability

• Blockchain 1.0 & 2.0: Limited scalability, difficulty in meeting the increasing number of users and applications.
• Blockchain 3.0: Improved scalability, but still faces challenges when the number of transactions increases dramatically.
• Blockchain 4.0: Superior scalability, allowing the system to handle large amounts of data and users without affecting performance. This helps Blockchain 4.0 meet the needs of large-scale applications and the development of the Internet.

Security

• Blockchain 1.0, 2.0 & 3.0: All have high security due to encryption and consensus mechanisms. However, there are still potential attack risks, especially 51% attacks on Blockchains using Proof-of-Work (PoW).
• Blockchain 4.0: Enhanced security with advanced encryption algorithms and new consensus mechanisms like improved Proof-of-Stake (PoS), minimizing attack risks and ensuring data security.

Applicability

• Blockchain 1.0: Mainly applied in the field of cryptocurrencies (Bitcoin).
• Blockchain 2.0: Expanded applications to smart contracts, allowing for the automation of agreements and transactions.
• Blockchain 3.0: Diverse applications in many fields such as supply chain, healthcare, and identity management.
• Blockchain 4.0: Highest applicability, can be integrated into almost every aspect of life, from finance and banking to healthcare, education, real estate, and energy.

Blockchain 4.0 is a significant advancement over previous versions, offering notable improvements in processing speed, scalability, security, and applicability. It not only addresses the limitations of previous versions but also opens up new opportunities for the development of Blockchain technology and its applications in the future.
