Oh, thank you for this words, it's mean a lot for our team As for your question, as data is expected to arrive in the new 'Data Economy' era, which serves as a catalyst for the development of all industries and the creation of new values, ReapChain ​​utilizes the infrastructure of ReapChain ​​to collect and store numerous IoT data. Based on the data, the data is shared with other industrial platforms such as medicine and finance, and data is shared with each other. Based on this open data-sharing platform, high-quality data distribution among all industries is promoted. We want to realize a Blockchain-based sharing economy ecosystem by acting as a hub for a platform ecosystem where we can register, search, and trade easily and quickly.

Differentiated Security of REAP Crypto Wallet

1. We do not store the private key inside the app, and the key imported from the outside and the private key generated when creating the wallet are encrypted and stored with the user password.

2. All transmitted transactions are encrypted with a private key and transmitted to the blockchain, so transaction forgery is almost impossible, and private key information is not exposed to the network.

3. Since it is a cold wallet in the form of a mobile app, it communicates directly with a blockchain network without a backEnd server, unlike a web-type wallet, so there is no risk of a private key exposure caused by the server being attacked.

4. Because the private key is not stored inside the app, even if the device is lost or exposed, it is impossible to steal the private key of the corresponding wallet because only the encrypted key-store file exists.

There exist hybrid chains that combine many public and private chains in the past, but ReapChain is different from existing hybrid blockchains.

​The existing hybrid blockchain was launched to solve the processing speed of the existing blockchain by synchronizing the two chains by pre-processing through the private blockchain and recording the final record in the public blockchain. However, since the existing hybrid chain uses private as a sidechain concept, it still has the problems of the existing private blockchain, and there have been many issues in solving integrity with the public chain.

However, the concept of the ReapMiddleChain on the outskirts of the ReapChain is different from the existing private blockchain, so a third party agrees on the authenticity of each transaction unit, constructs the chain in cell block units, and executes the transaction processed by the Gawon. By delivering it to the public blockchain, the ReapChain mainnet, we solved the security and integrity problems of the existing hybrid blockchain.

In addition, since the existing hybrid blockchain also achieves consensus through block generation, data cannot be confirmed until consensus is reached, so real-time processing speed cannot be guaranteed, but ReapMiddleChain is a transaction regardless of the block creation time. Because processing is performed separately, real-time processing speed can be guaranteed.

By implementing a hybrid blockchain, it is the only blockchain that can enable real-time processing of dApps by providing preconfirmation, which is a 99% reliable consensus before block creation.

The trillema problem (scalability, decentralization, security), which is the problem of the existing blockchain, was solved by ReapChain as follows.

1. Scalability has improved the mass data processing and processing speed through the middle chain.

2. Decentralization solved the element of centralization by providing 52% of the PoDC consensus structure of the operating committee.

3. Security can be prevented in advance by implementing a private + public hybrid block chain, which is a shell core structure, so that the external private chain protects against external attacks. Attack can be defended.

So, ReapChain launch their Waller App and did User Guide for REAP Wallet (ver. App). You can find all information in this article

The IoT industry is growing explosively, and it is being used so much that it can be found around us.

IoT is a technology in which literally all things connected to the Internet are controlled, and IoT is a field in which the data used must process mass data and response to real-time processing results is required. And due to the nature of IoT devices, there are security vulnerabilities caused by hacking.

By applying ReapChain to IoT devices, mass data processing is possible through the worm storage of ReapMiddlechain, and real-time response is possible through a three-party agreement on a cell-by-cell basis of ReapMiddlechain to respond to real-time processing results that existing blockchains cannot.

​The security issues of IoT devices can be assigned a unique private key to each device through Reapchain's PID MCU, so that the device's access rights can be controlled through the blockchain, thus avoiding the risk of external hacking.

Reapchain can bring the effect of reducing maintenance costs by realizing stronger security and processing of large-capacity data that does not require edge technology through the perfect combination of IoT industry and blockchain.

Recently, our team has signed many important partnership agreements. ReapChain X KAIST Synosia Lab MOU for example.



The business model and market using ReapChain’s technology verification (PoDC consensus structure, dual chain performance verification) will be analyzed to present milestones for new technology development and new market entry.

ReapChain X Kuno Soft MOU



ReapChain and KunoSoft agreed that security issues for individual objects should be resolved at a time when the issue of security vulnerabilities against external attacks is emerging in the existing IoT system. Through this agreement, both sides will jointly research and develop a global standard decentralized identity verification system based on lip chain that solves the existing trilemma problem of the blockchain, and secure and commercialize the ecosystem of the blockchain-based IoT platform service.

In addition, the two companies are planning to provide IoT security service that minimizes inconvenience to users by researching ways to enhance IoT security and to make it more convenient for users to use through S2K authentication technology of Kunosoft.

Blockchain can be largely divided into public and private chains.

Public blockchain is highly decentralized because anyone can participate in the consensus process without restriction, but since it is possible to participate without restriction, the processing speed in the consensus process may be slow and there may be difficulty in actual use.

Private blockchains can participate only by authorized users, so the consensus processing speed is fast.

However, since the number of users that can participate is limited, it is less scalable and vulnerable to security due to the presence of centralization, and it is deviating from the decentralization, the basic idea of the blockchain.

You can see that each blockchain has its own strengths and weaknesses. So we focused on designing a complete blockchain by combining only the strengths of each chain, so the shell-core structure was born.

QRF Mechanism: Consensus is established in the ReapChain by utilizing quantum random numbers, public-key encryption, and public key hash for fast recognition. A series of authentication and information transfer systems has named Quantum Random Function Mechanism. QRF provides a functional element by using a quantum random number server (Qmanager).

ReapChain is a hybrid blockchain with a dual structure that combines private and public.

The structure was designed with a private blockchain on the outside and a public blockchain on the inside, and it was named after the shell-core structure and the shape of the shell surrounding the center.

​This shell core structure is designed to solve the problem of the existing blockchain.

​It solved the problem of scalability by enabling mass data processing and high-speed processing through the external reap middle chain (private chain), and provided 52% of the operating committee's occupancy through the PoDC consensus structure of the internal ReapChain to provide the centralization factor.

Security implements a hybrid blockchain that combines a private blockchain with a public blockchain, allowing external private chains to defend against external attacks in advance, and has 48% of the good standing agreement, 51% attack, etc.

1) The nodes that participate in the consensus; the percentage of the steering committee nodes is maintained at 52% or higher to monitor whether or not the continually operating standing committee nodes have produced relatively.

2) As for the selection of the consensus participant, quantum random numbers are used to relatively select and distributed to the validator nodes, and then quantum random numbers and public keys are used again to assign encrypted random number tickets. A library of hardware-dependent call functions in which an unhackable message delivery system and fast authentication and consensus are implemented and named as Quantum Random Number Management Server (Qmanager).

3) Because of the hardware-dependent characteristic of quantum random number generation, Qmanager can either exist separately from the nodes.

4) The quantum random function mechanism has adopted for the role of Qmanager and the differentiating features of the REAP CHAIN contained in the QRF mechanism.

New vision of ReapChain is saying that they want to establish a new hybrid blockchain with Shell-Core structure unique to ReapChain that solves the trilemma of existing blockchains.

- To develop a double-layered chain structure that connects with various main net protocols
- To create a real-time data processing algorithm for DApp through the pre-confirm process
- To create a decentralized algorithm through the PoDC consensus structure.

In particular, as IoT technologies related to hardware and network develop rapidly, many discussions have been made regarding the integration of IoT and blockchain. It is expected that the blockchain technology will be utilized in various fields such as manufacturing process tracking and management process through the IoT technology in the future. ReapChain aims to establish a safe and transparent ecosystem of the blockchain industry for all the DApp (Decentralized Application) service providers by providing a usable blockchain.

Of course, we always try to answer all questions RepaChain’s consensus algorithm quickly generates blocks by conducting votes in the standing and steering committee that use quantum random numbers (QRN). In ReapChain, 48% of the operating standing committee nodes and 52% of the general nodes have selected, and each of the nodes acts as a subject and verifier of the block generation that participates in the consensus process.
