🌟 [ANN][REAP] ReapChain - Secure and Transparent Blockchain-Based IoT Ecosystem

[reap_chain]

As I see there are four nodes in the RipChain system, and each has its own task and purpose. I'm interested about governance node and it's purpose in the system.

To understand what it's doing you need to know what it is Governance node: Special node that controls fee and dividend policy, general node selection policy, and all other types of node management related policy.

REAP serves as a fuel in the ReapChain ecosystem. Transaction fee is paid as reward or incentive to holders of REAP or participants who maintain the network through transaction verification or block creation.

Transaction fee is paid as reward during random creation of the 600,000 to 700,000th block or when the amount of accumulated transaction fee reaches 1 million REAP. In addition, if the accumulated amount exceeds the upper limit at the time of distribution, reward is paid including the exceeded amount.

REAP holders, the standing committee nodes, and steering committee nodes and its candidate nodes also get reward to vitalize the ReapChain ecosystem.

What I found is allocation ratio of transaction fee is 70% for REAP holders, 20% for the steering committee nodes and its candidate nodes, and 10% for the standing committee nodes allowing double dipping. I think it would be interesting to somebody

ReapChain is a hybrid blockchain with a Shell-Core Structure. It solves the trilemma of existing blockchains and tries to implement the integration of blockchain and IoT industry by resolving the security and mass data processing problems of the existing IoT market through PID of things and distributed storage service of ReapMiddleChain.

Ecosystem



Participants in the ReapChain ecosystem will be a member of the IoT-based 4th industrial ecosystem and will contribute to the development of the IoT industry while gaining economic benefits.

[Vital_Z]

As IoT services start, the number of thing connected to the network is rapidly increasing. The increased number of thing incurs an increase in data traffic. In particular, with the advent of the concept of Wearable and Connected Car, data traffic is expected to surge in infotainment area (Information + Entertainment).

Most companies manage IoT devices by renting computing resources from cloud service providers. The existing cloud system is inefficient to process a large amount of data in the IoT environment as the centralized server processes all the data causing the lowering of the speed and quality of the entire IoT services.

In order to reduce data traffic burden and delays in providing services, “edge computing” technology is used to process realtime data on distributed small servers. Nevertheless, there are still difficulties in maintaining facilities or configuring systems because edge computing needs a separate process to handle computation.

I got into a part of the project description that was not entirely clear to me and would like to know more about it. What is ReapChain's consensus algorithm?

It's ok, we have interesting system, which has many technical solutions ReapChain is a Proof of Double Committee (PoDC) consensus algorithm that improves DPoS (Proof of Delegate) and Byzantine Problem (BFT). ReapChain combines 14 standing committee nodes and 15 steering committee nodes, and a total of 29 nodes participate in the consensus process for block creation. The proportion of nodes participating in the Steering Committee node is always maintained at 51% or higher, and the Steering Committee node is randomly selected as a strong quantum random number among general nodes.

PoDC (Proof of Double Committee) consensus algorithm

https://medium.com/reapchain/podc-proof-of-double-committee-consensus-algorithm-4c8680cc293b



In essence, the key problem with blockchain distributed ledgers is the random selection of block creators. This randomness can be seen across the entire network and must be absolutely impossible to manipulate and predictable. If not, a malicious node can manipulate the random number to control the main chain for a long time. Therefore, double-payment attacks can also be achieved.

ReapChain’s algorithm is a method to improve the problem of this consensus, and the block generation is agreed through a random method through double committee and quantum random number.

[reap_chain]

This article about Proof of Double Committee consensus algorithm is looking interesting. So what can you tell about standing committee nodes?

Standing committee nodes: 14 Nodes that operate all the times in ReapChain and have authority to create a block by participating in consensus process. (condition for the standing committee node: 2% stakes of the total issuance [98 million REAP] staking)

The standing committee nodes initially operates in the governance community. It can be further selected by those candidates that meet the particular criteria of standing committee amongst the steering committee nodes. And if any of the existing standing committee nodes are suspended or fail to meet the criteria, then those nodes must go through a separate voting process of the governance to be promoted from steering to standing committee node status.

[reap_chain]

As i see PoDC consensus algorithm consist of standing committee and steering committee. What about steering committee nodes and their functions?

Steering committee nodes: 15 randomly selected nodes among steering committee candidate nodes by using quantum random number, and can participate in consensus process to verify transaction(condition for the steering committee node: Stake of 100,000 REAP).

I'm trying to figure it out, but it's not that easy. It seems to me that the project is not so simple and its technical side is at a very high level.

Benefit



ReapChain aims to be a platform-sharing economic business model that anyone can easily use by providing economic incentives for Blockchain participants to voluntarily activate ReapChain. Through this, we intend to form a virtuous cycle structure in which IoT-based infrastructure and data are enriched and the IoT industry is activated by creating a structure that participates in the ReapChain ecosystem organically and is rewarded accordingly.

[reap_chain]

It is interesting to know more useful information about ReapChain consensus algorithm. What can you tell more about PoDC Consensus Model?

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.

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.

[nicko122]

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.
