Since the beginning of 2015, the concept of blockchain has started to gain attention. Before that, blockchain was merely a data structure used in Bitcoin technology. In Satoshi Nakamoto's whitepaper, the term "block and chain" referred to a simple chain of blocks. With the introduction of Ethereum’s idea of a decentralized computer, many began referring to Ethereum as Blockchain 2.0, while Bitcoin was labeled as Blockchain 1.0. As for Blockchain 3.0, some projects claim to be the real next generation, with technologies like DAG (Directed Acyclic Graph) being considered as potential candidates.
DAG, or Directed Acyclic Graph, is a well-known data structure in computer science. It is widely used for dynamic programming, navigation systems, and data compression due to its unique topological properties. The first time DAG was integrated into blockchain was in the Nxt community. The main goal was to improve the efficiency of traditional blockchains. Bitcoin, for example, has relatively low efficiency due to its consensus mechanism and linear block structure, which allows only one block to be processed at a time.
To address this, some proposed using DAG to store blocks instead of chaining them. This approach allowed different chains to handle different types of transactions, reducing the risk of double-spending. Later, nodes would merge these branches into a single block. In contrast, the current Bitcoin blockchain stores all transactions within a single block, with miners competing to validate each block every 10 minutes on average.
The Nxt community introduced the idea of replacing the traditional block structure with a DAG-based model. This enabled multiple blocks to be processed in parallel, significantly increasing network throughput. However, even in these early implementations, DAG still retained the concept of blocks, functioning more like sidechains.
Recently, projects like IOTA, Byteball, and ITC have taken this concept further by eliminating blocks entirely. Instead of waiting for a block to be mined, transactions are directly added to the network, achieving a "blockless" system. This reduces confirmation times and improves scalability. In Bitcoin, blocks are essential for organizing transactions, but in DAG-based networks, each transaction independently contributes to maintaining the network's order.
This shift has led to significant improvements in performance. Without the need for mining, transaction confirmations happen faster, and fees are drastically reduced. For instance, ITC has seen a dramatic increase in market value, with a single-month price surge of over 552%.
Key features of DAG-based blockchains include:
1. **Fast Transaction Speed**: Transactions are confirmed almost instantly, without the need for block packaging.
2. **No Mining Required**: The network itself validates transactions, removing the need for miners.
3. **Low or No Fees**: Since there's no competition among miners, transaction costs are minimal, making it ideal for microtransactions.
As the first blockchain project based on DAG in China, ITC has attracted considerable attention from both investors and developers. Institutions like FBG and ChainFunder have shown interest in its potential. From a technical perspective, DAG offers a completely new approach to blockchain design, with high performance and zero fees being major advantages. As the community continues to explore and develop DAG technology, it may very well become the true Blockchain 3.0.
