Difference between traditional centralized ledgers & DAG ledgers in Blockchain

Blockchain technology has revolutionized how we think about digital transactions and data storage. One of the key features of blockchain is its ability to create decentralized ledgers, which are essentially databases spread across multiple nodes in a network rather than being controlled by a single entity.

Difference between Centralized Ledgers & DAG Ledgers:

Traditional centralized ledgers, such as those used by banks and other financial institutions, have a single point of control and are vulnerable to hacking and other forms of tampering. In contrast, decentralized ledgers, such as those used in blockchain DAG ledger, are spread across multiple nodes, making them much more resistant to tampering and hacking.

Directed Acyclic Graph or DAG ledgers are a newer type of decentralized ledger technology that is gaining popularity in the blockchain space. DAG ledgers are different from traditional blockchain ledgers in several ways.

One of the main differences between DAG and traditional blockchain ledgers is how they handle transactions. In a conventional blockchain, transactions are grouped into blocks and linearly added to the chain. In a DAG ledger, however, transactions are not grouped into blocks and are instead added to the network in parallel, creating a web-like structure.

This allows for much faster transaction processing times and much higher scalability than traditional blockchain ledgers. DAG ledgers can handle thousands of transactions per second, while conventional blockchain ledgers are typically limited to just a few transactions per second.

Another significant difference between DAG and traditional blockchain ledgers is how they handle consensus. In a traditional blockchain, a consensus is achieved through a process known as mining, in which powerful computers compete to solve complex mathematical problems to validate and add transactions to the chain. In a DAG ledger, however, a consensus is achieved through a process known as “voting,” where each node in the network confirms the validity of a transaction by approving it.

This eliminates the need for mining, which can be energy-intensive and costly. It also allows for much faster transaction validation times and eliminates the need for powerful mining hardware.

DAG ledgers also have a unique mechanism for preventing double-spending and Sybil attacks, a common problem with traditional blockchains. In a traditional blockchain, a malicious actor can create multiple identities and use them to spend the exact digital asset numerous times. But in a DAG ledger, each transaction is linked to a previous transaction, creating a unique chain of ownership for each digital asset. This makes it much more difficult for a malicious actor to create multiple identities and spend the same digital asset multiple times.

Ending Note:

DAG ledgers offer several advantages over traditional blockchain ledgers, including faster transaction processing times, higher scalability, and more efficient consensus mechanisms. These advantages make DAG ledgers a promising technology for many applications, including digital payments, supply chain management, and more.
