IOTA's Tangle: Unraveling the Advantages of Blockchain

Updated: Aug 26, 2023


The advent of blockchain technology revolutionized various sectors, introducing newfound transparency and security. However, as technology progresses, so does the need for innovation. Enter IOTA, a groundbreaking distributed ledger technology called Tangle based on the Directed Acyclic Graph (DAG). the benefits that Tangle offers over the conventional blockchain, highlighting the key differences between the two.


Blockchain: One of the primary challenges blockchain technology faces is its scalability issue. The linear nature of blockchain platforms, where transactions are added to a single chain, has resulted in slower transaction speeds as the network grows. This limitation is often a bottleneck in scaling up to meet the increasing demands of real-world applications.

Tangle: In contrast, Tangle employs a DAG, enabling parallel processing of multiple transactions. This feature inherently resolves the scalability issue faced by blockchain. As more nodes join the network, the transaction confirmation rate increases due to Tangle's ability to process multiple transactions simultaneously in a decentralized manner. Consequently, Tangle showcases higher throughput and eliminates fee-based transactions, making it suitable for scalable applications such as the Internet of Things (IoT).

Transaction Fees:

Blockchain: Traditional blockchain systems often require transaction fees for miners to prioritize and confirm transactions. These fees can be significant, especially for microtransactions, hindering the widespread adoption of blockchain technology. Additionally, with the increasing size of blockchain networks, fees may escalate even further, reducing the practicality of low-value transactions.

Tangle: Tangle's unique structure eliminates the need for transaction fees entirely. Instead of miners, IOTA utilizes a "pay-it-forward" mechanism where each user contributes to the network's consensus by validating two previous transactions. This approach ensures the accessibility of microtransactions while incentivizing a more equitable distributed ledger ecosystem.

Energy Efficiency:

Blockchain: The energy consumption of most blockchain networks, particularly those utilizing Proof of Work (PoW) consensus algorithms, has sparked debates regarding their sustainability. These energy-intensive systems require substantial computational power to solve complex mathematical problems, leading to enormous electricity consumption and environmental concerns.

Tangle: Tangle adopts the innovative "Proof-of-Work consensus" mechanism, which significantly reduces energy consumption compared to traditional blockchain networks. Each new transaction must validate two existing transactions, eliminating the need for resource-intensive mining operations. Consequently, Tangle allows for a more eco-friendly approach, ensuring a sustainable and green distributed ledger system.

Decentralization and Security:

Blockchain: Although blockchain has been hailed for its decentralized nature, the presence of mining pools and the potential for a 51% attack raise concerns regarding true decentralization. Additionally, the growing size of blockchain networks may increase vulnerability to malicious attacks, further undermining security.

Tangle: Tangle offers enhanced decentralization and security through its unique structure. Unlike blockchain, Tangle does not rely on miners but instead empowers all users, effectively eliminating the need for specialized hardware. By validating two previous transactions, each user becomes an integral part of the consensus process, enhancing decentralization. Moreover, Tangle’s structure ensures the network strengthens as more nodes join, making it inherently more resistant to attacks.

Adoption and Integration:

Blockchain: The adoption of blockchain technology faces barriers due to its complex infrastructure, long confirmation times, and transaction fees. Integrating blockchain into existing systems often requires significant modifications and can be time-consuming and costly for businesses.


Tangle's feeless and scalable architecture, combined with its streamlined integration capabilities, make it an attractive choice for organizations seeking frictionless adoption of distributed ledger technology. With reduced barriers, businesses can smoothly incorporate Tangle into their operations, benefiting from its inherent advantages without the complexities associated with blockchain integration.

IOTA's Tangle offers numerous advantages over conventional blockchain technology. Its scalability, elimination of transaction fees, energy efficiency, enhanced decentralization, and seamless integration make it an innovative solution for various industries. As technology continues to evolve, the unique properties of Tangle open doors to exciting possibilities, revolutionizing how we embrace distributed ledgers in the future.
