Saemyeong Energy Tech Group

Saemyeong Energy Tech Group is

a company specializing in research and development of eco-friendly products, and aims to supply raw materials such as high-performance combustion catalysts, lubricants, organic natural fertilizers, soil conditioners, feed additives, and bioceramics to the world. After China and Vietnam, we started to expand to Southeast Asia and Europe.

Saemyeong Energy Tech Group is adhering to the new strategic direction of block chain and eco-friendly energy in its overseas development strategy, so we propose an HRDG tree-type block chain that transparently distributes the entire distribution process of eco-friendly products to all subsidiaries through block chain technology.

By uploading it to the block, we will maximize the company's profits and at the same time provide various investment opportunities to ecosystem investors. As a resut, we will grow into a global symbolic eco-friendly energy company.

HRDG Ecosystem

  • P2P eco-friendly energy transaction

    It is to enable energy consumers to actively participate in energy transactions and become energy prosumers. The prosumer referred to here not only general household energy consumers, but also commercial and industrial energy consumers can play the role of prosumers including trading physical and information in an end-to-end manner.

  • Mass transaction of eco-friendly energy

    Energy trading is completed through common market mechanisms such as oil trading within blocks after packing information into blocks. It can automatically execute terms and conditions based on pre-set multi-conditions. It also automates procedures such as electronic documents, smart contracts and authentication transfers. So it is possibler to reduce transaction costs and risks significantly

  • Eco-friendly energy smart service

    By utilizing the characteristics of transparent & safe blockchain and the advantages of smart contracts, eco-friendly energy companies can increase the level of smartization of their current work and provide more various smart value-added services. In addition, by applying smart contracts to wholesale transactions of eco-friendly energy, transaction risks and management costs can be reduced.

  • Tracking of eco-friendly energy assets

    Supply chain management and tracking function of blockchain technology enable the most basic functions such as anti-counterfeiting inquiry and consumer feedback, not only product information such as brand, country of origin, selling point but also company-related information such as company level and safety certification. It also enables information retrieval on import certificates, import cargo quarantine certificates, customs declarations, etc.

  • Supply chain finance

    Supply chain finance is a system in which all participants (suppliers, importers, banks) share documents through a decentralized ledger and pay automatically when a scheduled time or result is reached. This increases efficiency and at the same time prevents errors caused by manual transactions, and creates a smooth information flow throughout the entire supply chain, maximizing the efficiency of supply chain management.

Introduction to Blockchain

The HRDGCOIN Team develops the HRDGCOIN ecosystem and issues HRDGCOIN by gathering eco-friendly energy developers and blockchain experts to solve various problems in the eco-friendly energy market and the global overseas remittance market. HRDGCOIN is used as a key currency within the eco-friendly energy and global fintech ecosystem.

  • HRDGCOIN economy without borders
    Without borders, all members of the economy, energy, fintech and countries around the world will be united with the word HRDGCOIN Network. And they will become a member of the HRDGCOIN ecosystem.
  • Public security through Public & Personal decentralization
    It refers to the structure of an ecosystem through realization of public security through decentralized information management, which is the security core of blockchain technology and coexistence between individuals and the public.
  • Highest speed and real-time processing for energy and fintech commercialization
    The HRDGCOIN platform, a third-generation blockchain, will become a world standard energy and fintech PUI blockchain based on real-time reflection and fast block processing, which is very important for energy and fintech.


HRDGCOIN Technical Frame

HRDG provides a complete development model and technology frame
for the entire blockchain technology ecosystem.

The combination of blockchain technology and eco-friendly energy industry using a design method verified through long-term experiments is a epochal leap forward.
More importantly, HRDG has laid an excellent foundation that will go down in history in the ecosystem through the combination of blockchain technology and the eco-friendly energy industry.

  • Network layer

    After generating block data by executing the core node program on the network node of HRDG, it performs functions such as simultaneous data update between each node.

  • Tree structure

    It stores system block data through a tree-type block structure based on 'Security Main Chain + Multiple Application Sub-chains'

  • Cross-chain template

    HRDG cross-chain templates and e-commerce templates do not require a VM compiler and have excellent operational efficiency.

FCC (Fuel Combustion Catalyzer)

In general, incomplete combustio occurs because the oxygen supply inside the fuel is not smooth.

  1. → Fuel + FCC mixture → Combustion temperature rises to a constant temperature → Oxygen is generated from FCC
  2. → FCC supplies oxygen to fuel that lacks oxygen → promotes complete combustion of fuel
  3. Fuel savings + reduced air pollutant emissions

Manganese Mine

Located in Maranje Province in the northwestern Republic of Angola, the mine is 15km wide to the south and is 268m high with a minimum of 840m above sea level and a maximum of 1108m above sea level. The direction of the main ridge is northwest-southeast, and gradually changes to the north-south direction to the east, with gentle hills in the middle and high mountains in the north. The total mining area is 576㎢

Metamorphic rocks of the old ancient system, an old basal primordial system, and the sporadically distributed Mesozoic Cenozoic strata. The strata are the old basal and cover layers, respectively, from old to new layers.

Archaeological subgroup (Ag1)1) Contains manganese granitic gneiss, ileal gneiss, metamorphic rock and forms iron manganese deposits related to sedimentary alteration. It is the main layer of the manganese oxide mine in Angola.

Ancient Sangam Cluster (Ag1)2) It is composed of Baegun 2 gneiss, granite gneiss, schist, amphibole and magnetite quartzite. As a result, the growth of quartz rock, which is a lithotropic magnet, became common. And iron ore deposits related to the drying of silicate were frequently formed, reflecting the main stratum of Angola's iron ore and manganese carbonate ore.

Old ancient lower rock cluster(Pt1)1) gneiss, layered andesan basalt.

The old ancient Sangam Cluster (PT1)2) Rock formations are mainly composed of clasts and carbonate rocks, and are major deposits of nonferrous metals such as Angola copper, sedimentary iron and manganese deposits. This rock was found to form mixed granite due to the occurrence of mixed rocks in different amounts within the premises.

In the stratification, the main system (K) - the tertiary system (N) - the quaternary system (Q) are mainly distributed sporadically. Among them, the Cretaceous period and the Tertiary period are carbonate rocks and clasts, and the carbonate rocks are Angola cement which is the main producer of gray rock.
