不同于我之前关于ITC万物链的文章，本文将区分ITC和IOTA之间的区别，以及对有向无环图（DAG）架构的使用。

定向非循环图（DAG）体系架构

DAG体系架构是分布式体系结构，而不是重链接的区块链结构，这不仅解决了比特币挖掘的集中化问题，而且大大提高了整个分布式网络的吞吐能力，降低了交易成本。DAG架构被称为是下一代的区块链。

众所周知IOTA网络架构主要基于DAG，但为什么万物链的方法比IOTA更好？

IOTA的复杂性

可以从一个特定的方面进行比较，IOTA技术是好的，但他们没有自己的芯片。为了使用IOTA，您需要对区块链网络有一个很好的理解。如果有人想利用这个技术，IOTA将不得不引导这些组织或客户到GitHub，您必须从这里了解缠结、协议、语言，这是一个更为细节和复杂的过程。

ITC万物链的简单

如果您使用ITC操作系统，只需要一种使用芯片的方式，芯片中已经有了软件，您只需要以稳妥和安全的方式，将芯片插入到您的设备。组织和客户不需要了解它的技术方面。ITC已经建立了合作伙伴关系，因此他们的方法对于组织和客户来说是用户友好型的。只需在设备上插入芯片，一切都在方便用户！只有大公司才会了解底层技术，大部分的小公司将无法理解这种复杂的技术。这将避免一个非常耗时的过程。

ITC采用DAG的数据结构来解决性能问题。一方面可以提高交易绩效，另一方面可以抵抗量子攻击。总之，ITC将为物联网设备提供基于DAG架构的操作系统，在交易的安全性和确认速度方面是最好的！

IoT Chain (ITC) or IOTA

In relation to my previous article about IoT Chain (ITC), this article will distinguish the difference between ITC and IOTA, and the use of Directed Acyclic Graph (DAG) architecture.

Directed Acyclic Graph (DAG) architecture

DAG architecture is a distributed architecture instead of the heavy linked blockchain structure, this will not solve only the present problem of centralization of Bitcoin’s mining but also greatly improves the whole distributed network’s throughput capacity and lowering the transaction cost. DAG architecture is the next generation’s blockchain.

IOTA network utilizes DAG specifically, but why is the approach of IoT Chain better than IOTA?

Complexity of IOTA

The comparison could be made on one specific aspect, IOTA technology is good, but they don’t have their own chips. In order to make use of IOTA, you need a good understanding of the blockchain network. If you want to make use of this technology, IOTA will have to refer any organization or customer to GitHub, you have to understand the tangle, the protocols, the language, it’s a much more detailed and complicated process.

Simplicity of IoT Chain (ITC)

If you make use of the ITC operating system, it’s just a way of using the chip, the software is already there in the chip, you just have to plug the chip in your device and everything its there, in a secure and safe way. Organizations and customers don’t need to understand the technical aspects of this technology. ITC already established partnerships and therefore their approach is user-friendly for organizations and customers. Just plugging the chip in your device, and everything is been taking care of! Only the big companies will understand the underlying technology, most of the small companies will not be able to understand this complex technology. This will avoid a very time-consuming process.

ITC adopts DAG’s data structure to solve performance problems. On the one hand, the transaction performance can be improved. On the other hand, ITC can resist quantum attack. After all, ITC will provide an operating system with the Directed Acyclic Graph (DAG) architecture for IoT devices, the best in terms of security and confirmation speed of transaction!
