What is PID of Things (Private ID) and what role does it play? How it connects with the other parts of ReapChain system?

ReapChain implements a new object authentication system, PID of things by applying DID (Decentralized ID) technology which has been applied only to people, to each device through its unique encryption technology, Reap SDK. PID of things generates ‘unique ID’ (Private Key), and utilizes Invisible ID technology and Mutual verification technology to enhance security. Invisible ID technology does not allow unauthenticated users to see the unique ID of devices. Mutual verification technology allows transmitters only authenticated by Reapchain to communicate with IoT devices.

Blockchain trillema usually points to three issues: scalability, decentralization, and security. Bitcoin and Ethereum, for example, have a scalability problem that slows down the transaction processing speed per second (TPS) as the network expands. To solve this problem, the 3rd generation blockchain EOS appeared, but it has not yet been able to provide a sufficient solution.

ReapChain solves this problem with a hybrid blockchain with a shell-core structure and a new thing authentication system PID. The shell-core structure is a hybrid blockchain that combines ReapMiddleChain, private blockchain and public blockchain. It is a structure in which a fast private blockchain is placed outside and processed first in time. A public blockchain with strong security and decentralization is placed inside to enable dual processing.

It's interesting for me to know more about this projects. Can you please tell more about what made you start the ReapChain project?

I think we can give you an answer on this question

While creating a blockchain development company and developing related solutions, we encountered technical limitations of the mainnet. The security of the blockchain technology is excellent, all transactions until consensus, the biggest problem, are untrusted data, and it was difficult to apply to dApps.

Especially in the fields of financial, IoT and games, it was very unfortunate that we could not utilize complete blockchain technology because we had to process real-time data. The goal of the ReapChain project was really concise and solid. And now we are able to conceive and design a blockchain that can process data in real time with a dual chain, the basic structure of ReapChain.

What does ReapChain BaaS exactly means and what it represents? Is it consist of many different parts, which working together?

BaaS (Blockchain as a Service) is a cloud computing platform that provides a development environment for blockchain-based software. ReapChain BaaS is composed of 3 parts: Reap SDK, ReapMiddleChain and ReapChain, and Reap Platform. Reap SDK connects and authenticates devices. ReapMiddleChain and ReapChain process and store data. Reap Platform operates and manages of all services by business service providers.

How is ReapChain different from other mainnets and how can it help with new economic and technological advances in future

?

ReapChain consists of a middle chain and a mainnet in a double chain structure. Pre-confirmation is provided by pre-consensus on the actual processing speed in seconds, independent of the block generation time, with the middle chain as a temporary ledger concept.

Since it is a structure that finally confirms and confirms in accordance with the mainnet block creation time, it realizes the practically usable TPS speed. It can solve the speed problem of the existing public blockchain. The mainnet structure is public-oriented, it can solve the disadvantage of existing private blockchains, the scalability.

There are companies that develop blockchain technology for Internet of Things security overseas. Australia's Webjet has introduced it into its travel reservation confirmation service. The introduction of blockchain in the process of booking accommodation by travelers. The IoT sensor inside the hotel automatically stores the hotel's internal situation and puts it in the blockchain, preventing reservation changes (schedule or price, etc.) between the hotel and the consumer through the app. Using this, you can save transactions and time.

ReapChain consists of 14 standing committee nodes that operated at all times as well as 15 steering committee nodes that had selected from general nodes through unpredictable quantum random numbers comprises of robust security. These 29 committees participate in the consensus process for generating blocks. In order to ensure whether the standing committee that operated at all times is still working legally, the steering committee must account for at least 52% of all nodes that participate in the consensus process.

For now I just tried the app version of REAP Wallet, and I'm interested in try web version. Is the process of sending and receiving tokens harder there?

To send you just need to:

STEP 1. Enter the amount of REAP to send tokens.

STEP 2. Scan the wallet address QR code to send to the QR code scanner and enter the wallet address.

STEP 3. Click the “Authenticate” button to receive the authentication code from SMS.

STEP 4. Enter the authentication code received by SMS and click the ‘OK’ button.

STEP 5. Send REAP by entering the PIN number.

To receive:

STEP 1. Show QR code.

You can generate a QR code by entering the number of REAP tokens you will receive.

One of the fields that the IT industry has been interested in since before the 5G mobile communication era took its place is the Internet of Things (IoT). It is a technology that increases convenience by mounting sensors and communication functions on various objects. For example, if an air conditioner is equipped with a temperature sensor, camera, and a communication device, it analyzes the ambient temperature and movement of people to adjust the optimum temperature and wind strength. By utilizing the communication function, the power can be turned on and off from outside, and it is also possible to check the surrounding conditions with the camera.

Reap Wallet application seems to look complete and workable. It has many useful functions, you can even designate a representative wallet if you need it

Yea, that's true, if you designate the wallet as your representative wallet, it will be marked with a colored belt at the top of the wallet and will be moved to the first wallet.

You can manage multiple wallets and designate representative wallets to make them easier to use, so you can check them immediately when you run the wallet.

The blockchain mainnet is also one of ReapChain's business structures. It will provide a stable mainnet, so you will be charged a fee for it. It is said that it was planned as a commercial from the beginning, not a mainnet for showing off technology. In addition to this, data will be given ownership through the middle chain to industries included in the ecosystem. It is interpreted as the idea that the reward for the use of data will be distributed evenly to the ecosystem.
