Hdac Transaction Innovation


The Hdac platform will create a trusted basis for the fourth industrial revolution by combining the blockchain and IoT as an applied platform using fintech technology, creating a logical and efficient payment method, fulfilling the philosophy - ‘Transaction Innovation’.

Hdac*T (Hdac token) is a smart coin based on the blockchain issued on the Hdac platform. In an IoT environment, it is designed to perform given tasks regarding on the instruction conditions. Hdac supports the functioning of cryptocurrency and convenient payment services and seeks to be rational and efficient. Together, with the interconnectivity of IoT, Hdac will perform as a ‘Micro Payment Platform’. Furthermore, Hdac will evolve into a cryptocurrency-based, Fintech-specialized platform by strengthening the security for users to communicate, providing a hardware wallet for convenient payment to enable transactions through M2M(Machine to Machine) and IoT devices.


IoT (Internet of Things) and Security

The main keywords for IoT are ‘smart’ and ‘connection’. As the objects and devices unrelated to networks before are now being connected to the internet to provide a variety of services, it shares the existing threats and vulnerabilities of the internet. Also, not only does the problems caused by outer sources as mentioned above, the collected data on IoT could violate one’s privacy and insecure connections could lead to a social disaster. For a ‘hyper-connected society’ based on the IoT, it is essential to have a trusted P2P network system together along with trusted contracts and operations between IoT devices. This will lead to an ultra-advanced micro-payment system.


The use Blockchain for IoT applications

In an environment such as a smart home or smart factory, there are various devices (IoT) equipped with sensors and they are closely interconnected. Considering the conditions of each device, it is possible to form a private blockchain which can be operated in a safe and trusted manner. Private blockchains require not only the authentication of the user but also the authentication between devices, records of operation details, and the scenario-based IoT Contract should be able to operate. In addition, a private blockchain will only be practical if it interacts with an already operating public blockchain. Regarding to this, the user must configure Hdac, a cryptocurrency which will be used in the public blockchain, to create an effective application for it. We want to create a reliable ecosystem, making the public and the private blockchain interconnected, operating ‘Hybrid Payment Service’, where the general user side Hdac and the private purposeful blockchain interconnects. In other words, with the blockchains we will be creating according to the usage, and Micro Payment will be possible as well as P2P payment on the public blockchain. In a controlled private blockchain network, we implement Machine Currency for mutual contracts and payments between IoTs, fulfilling the slogan, ‘Transaction Innovation’, which enables rational consumption and payment.
Example of Private Blockchain by IoT usage


Securing Trust between IoT Device in the Blockchain

The connection structure of the IoT and the network structure of blockchains are shown in the image below.

By merging blockchain with IoT, it is easier to implement confidentiality and integrity - the vital factors to ensure reliable connections and secure the processing between the devices. This allows the connected devices to respond to fabrication and modification attacks and enhances the trust between the parties in communication. In particular, ledger in block of the blockchain is highly encrypted with complex mathematical encryptions, making it able to respond to external attacks. In addition, rather than a centralized method, the blockchain uses a decentralized method, which makes it difficult for the hackers to determine the target. These features minimize the impact of individual attacks on IoT devices and furthermore, the entire device. Trust based services between the IoT devices are summarized below:
  • P2P and the dispersion structure distributes targets, making it difficult for the attackers to determine the target → In the case of a private blockchain, if the distributed computing development is limited, the security issues can be solved by securing the network through the ‘Safe IP’ tool.
  • It is possible to maintain transparent through the trust based network, shares transaction details of the participants and store them reliably.
  • It guarantees the integrity of the transaction details to respond to counterfeit and falsification attacks - every participant proves the transaction details.
  • Authentication and authorization procedures of the principal IoT device are required.
  • In a public blockchain, it is possible to increase the efficiency of construction and maintenance according to the distribution. In addition, decentralization improves efficiency by reducing the construction cost and the efficient allocation of resources.
As a result, the network using the blockchain can provide a reliable environment for not only the communicated data, but both the administrator, whom set the network, and the user on the blockchain.
