Ⅰ. Technology of Attracoin

1. Blockchain Overview

Blockchain, a basic technology that supports bit coins, is one of the buzzwords of

the past year. Actually everyone is talking about the blockchain. An art terminology

for the basic technology of a blockchain, Distributed Ledger provides an exciting

new way to handle business without a central authority. The following is a non-

technical, brief description of the component parts.

1.1. Defined blockchain

A blockchain or distributed ledger is an ever-growing list of encrypted transactions

called "blocks" that are distributed to peer-to-peer computer networks.

1.2. Block

As described above, a blockchain is a series of constant, continuous record chains

known as blocks. A block can contain any type of data, such as the unique digital

identifier of the physical product. Blocks are "connected" together using a hash. A

hash is a function that takes an input value and generates a deterministic output

value of the input value from the input value.

In addition to user data, each block contains an index, a time stamp, a transaction

list, a proof of the previous block, and a hash.


4

1.3. Hash

Hashes play an important role. The blockchain can not be changed because the

new block contains the hash of the previous block. If the hacker compromises the

previous block in the blockchain, all subsequent blocks will contain the invalid hash.

1.4. Encrypted Transactions

Encrypted transactions (using existing public / private key encryption) are also key

to the blockchain. Your "public key" is stored in a block and becomes the "address"

of the blockchain. Files such as cryptocurrencies or other digital assets are recorded

as belonging to a specific block. A related "private key" is required to access the

associated digital assets. Keeping your private key private is very important, so

many people do not keep a digital copy of their private key to protect their digital

assets from hackers. They record numbers on paper and keep the paper in a safe

place (such as a wall safe).

1.5. API

The next step in developing a distributed book is to set up an application

programming interface (API) so that organizations that want to trade can do so

using the Internet. A transaction endpoint allows rights-based access to data in a

blockchain.

The API also has a "mining endpoint" feature that gives (1) PoW calculation, (2)

transaction addition, and miner compensation (bitcoin is a bit coin), and creates a

new block and adds it to the blockchain.

1.6. Peer-to-peer (mesh) network

Finally, the Distributed Ledger obtains authorization from being distributed and the

distributed. To achieve this, the Distributed General ledger needs a way to accept

new nodes, implement conflict algorithms to resolve conflicts, and ensure

blockchain accuracy.

This is done through a P2P or mesh network, where each computer (node) is a

distributed computer network that acts as a client (the computer that accesses

information on the server) and a server (the computer that provides information to

the client). P2P networks are self-healing and very reliable because information is

replicated in thousands, sometimes millions of places.

1.7. Public or private

There are two general types of blockchain networks. Anonymous network (each

user has a copy of the entire blockchain to help process and verify the transaction).

There is a permission-based (non-anonymous) network that has the necessary

permissions to own a copy of the blockchain and process and verify transactions.


5

1.8. What can you do with blockchains in addition to cryptocurrencies?

Blockchain provides a way to validate transactions without central authority. In other

words, you can create a wise agreement using a distributed ledger. For example, a

landlord can install an IoT door lock on a rental apartment. The door lock checks the

blockchain to see if the rent is paid. Otherwise, the door lock (that is, a smart

contract) will not allow to enter the apartment. In more complex cases, companies

can issue their own bonds and buyers can monitor payments through the

distribution ledger. A much more complex case would be the creation of a self-

enforcing trade agreement. Blockchain usage lists are virtually endless. From title

search to delivery confirmation, Deployed ledger provides a completely new and

secure business method.

2. Features of the blockchain

The future of finance can be dominated by blockchain technology. Tracking global

currencies completed with an efficient infrastructure will not only bring tremendous

cost savings to all market participants, but will also change global banking.

The blockchain will be adopted by the central bank, and password protected calls

will be widely used.

Resolving currency, equity and bond transactions almost immediately done

through licensed distribution ledgers creates a significant opportunity for banks to

increase efficiency and potentially create new asset classes.

Control

New technologies such as blockchains can reduce cyber risk by providing identity

authentication through visible ledgers.

There is no reason why the requirements for numbering, maintaining, and indexing

records, and delivering the information provided in records can not be met by the

electronic ledger system.

Car rental agencies can use smart contracts that automatically accept rental

agreements when payment is received and insurance information is confirmed

through blockchain records.

Refrigerators equipped with sensors and connected to the internet can use

blockchains to manage the automatic interaction with the outside world. From

ordering and paying for food to preparing your own software upgrade and tracking

your warranty.

Small businesses can use blockchains to create a reliable trading platform.

Blockchain can potentially bring robustness and transparency to the post-trade

environment.

The bank can immediately pay the vendor via the internet.


6

Crime

New blockchain start-up allows software to track criminals faster and cheaper.

Bank

The blockchain will be adopted by the central bank and password protected calls

will be widely used.

Blockchain can replace the central bank.

There is a real risk to the bank that decides to join the cryptocurrency company.

Blockchain technology can reduce cross-border settlement, securities trading and

regulatory compliance costs.

You can reduce the number of applications inside and outside of the bank because

the Blockchain transaction contains all relevant information for the successful

transfer of assets and / or related contracts.

It is a much more general purpose than bit coin, and there will be many coins

available for banks.

The future of finance in many countries can be dominated by Bitcoin and

cryptocurrencies.

The bank can be the "cryptographic key manager".

Blockchain can save up to tens of billions of dollars annually when making a

payment.

Blockchain technology can be used to completely bypass today's centralized

financial infrastructure.

Industry

Blockchain is likely to create new industry opportunities and confuse existing

technologies and processes.

Blockchain technology makes the world smaller by improving the speed and

efficiency of transaction activity.

Government

The future of finance in many countries can be dominated by Bitcoin and other

cryptocurrencies.

Blockchain technology can be used to distribute social welfare in developing

countries.

The elections are currently time-consuming and costly, and in many countries, we

expect to use Blockchain to make a rational, democratic election.

3. Attracoin

3.1. Summary

Thousands of encryption currencies have been created globally, and thousands and

tens of thousands of encryption currencies will be created and vanished in the

future.

However, there are no coins that can be used right now in the real world, and the

future of coins without these usages will lead to the cancellation of the listing.

Users have a lot of concerns, such as lost smartphones or lost passwords for

personal wallets storing encrypted currency. In fact, if you forget your password and

can not use or recover your encryption currency, it is one of the most frequent

incidents that you are already experiencing. Attra was designed and built as a coin

with all the security and ease of use of the asset, just like leaving it to the bank.

3.2. Purpose

AttraCoin is available in real life, enabling you to quickly and securely develop

encrypted currency and protect your assets the most.

It protects user's assets safely from personal hacking with password setting, paper

wallet etc. as well as user's biometric information.

Attracoin is the fastest encryption currency available in real life, and it develops various technologies such as merchant, ATM, and online payment and provides people free of charge with the convenience of users and the basis for using their assets in their lives as goods.

3.2.1. Goal

The user chooses which blockchain to use, and it gives compensation accordingly.

In other words, if the main blockchain is stored in its own computer, the user can

receive the network interest so as to train the user who stores the main blockchain

and stabilize the main blockchain.

The encryption algorithm uses SHA256 approved by NASA, which does not have

hash collision, to be customized for Attracoin.

Implement a wallet that is more complete and secure than any encryption wallet in

the world.

Use biometric technology to completely protect your assets and make it easy for

you to inherit assets.

Instead of the existing slow blockchain, the duplicated blockchain technology

achieves transmission speed of less than 1 second.


8

3.2.2. Technology and Vision

• The safest Attra wallet is designed to contain a variety of encrypted currencies,

such as Bitcoin, Etherium, and Light Coin, as well as Attra, all to be protected by

Attra wallet.

• Connects biometric technology to Attra Wallet to create the world's most secure

wallet and protect user and user property by encrypting user's information.

• If the user intends to inherit his or her wallet to a specific person, the user should

register the information of the heirer in the user's wallet. If the user's consent is

obtained on a specific date or in a specific situation, implement a technique that

allows a user's assets to be transferred to the heir as the request.

• Through the implementation of this technology, Attracoin has become a standard

of authentic encryption currency and is responsible for improving the technology

of encrypted currency.

3.3. Security technology

3.3.1. Introduction of biometric technology

A financial transaction relay system with multiple security locks that handle user

authentication using biometric technology is the ultimate realization of an electronic

payment system and multiple security lockout certified security systems.

Using biometric technology, it encrypts the user's assets in conjunction with the

Attracoin electronic wallet, such as Android, iPhone, Windows Mobile Phone.

3.3.2. Technical achievement

Fingerprint recognition technology, which is a biometric technology, encrypts and

stores information and authenticates the user with this information shows the peak

of biometrics technology that overcomes the limitation of simple fingerprint

recognition. In addition, the biometric information recognition technology can be

used without any sense of rejection, and thus can be a method for reducing a user's

sense of rejection.

The recognized information is verified through encryption and decryption, and the

user can rest assured that his or her information will not be exposed and leaked.

Using biometrics increases the strength of security and anyone can not forcibly take

over the user's assets.

3.3.3. Future Plans

Attracoin's biometrics technology will be developed one step further by establishing

a payment system such as commerce so that anyone can conveniently authenticate

themselves and make payment in their own electronic wallets without the need for

separate user's electronic equipment.

In other words, our goal is to enable people to exercise their own properties anytime

and anywhere.


9

To do this, it is necessary to connect and manage the user 's electronic wallet

address and the user' s biometric information.

In the future, users will be able to recover their wallet with their own biometric

information at any time without having to back up their wallet separately.

3.3.4. Disclosure of technology

Attracoin's technologies are all based on open biometrics and encryption

technologies. We will continue to develop and upgrade for the development of the

encryption currency. We will release it to the world every time there is a successful

result, As well as leading to the encryption of money and the fourth industrial

revolution.

3.3.5. The safest purse

Smartphone wallets are always used by users with anxiety.

In addition, desktop computer wallets are also used with anxiety from various hacks

such as hacking and Ransomware.

If you set a password, you can check it by typing unlimited number of passwords. If

the program finds your password, it will not be long before you find the password for

that wallet and encrypt it. Money can be used as it is.

Attracoin's purse is the world's safest encrypted wallet that can not be opened or

used in any way unless the user of the wallet opens it.

It will be the safest wallet by already scanning biometric information and decrypting

encrypted and encrypted information, authenticating it, encrypting it again or

discarding the information.

3.3.6. Acceptance of persistent encryption currency

Attracoin's wallet contains not only Attra but also a variety of encrypted coin wallets

such as Bitcoin, Etherium, Ripple Coin and Light Coin, allowing users to store

various encrypted currencies in the safest Attra wallet And protects the user's assets

with various backups and redundant triple safety devices.

In other words, just using Attracoin's wallet will allow users to safeguard their

encrypted money assets safely and thoroughly.

Also, since the backed up information is not decrypted without its own biometric

information, it can be relieved even if its own backup information is leaked by

various hacks or the like.

4. Attra Blockchain

4.1. Redundant blockchain

The Attra blockchain is a redundant blockchain consisting of a main blockchain and

Attra blockchain.

The user can use his / her desired block among the main blockchain and the sub

blockchain, and the user who stores and shares both the main block and the sub

blockchain receives the network incentive.

This is due to some of the transfer fees given to the users as a result of their

contribution to the Attra blockchain, to those who keep and share Attra main

blockchains.

4.2. Attracoin Hash function The Scrypt is a typical encryption algorithm designed and certified by the US NSA

(Hashcash), which uses symmetric encryption, that is, to generate hashes from

input data. Let's assume that the data consists of the name Ada.

If you use a one-way key, this data is hacked to 000CFC Mail CFC Previously, ooo

is technically known as "Nonce." In English, Nonce is a word that is used once in its

meaning.

In the case of Attracoin, the nonce is a string of zeros placed before the input data to

create a unique jumble of data, but this is a very simple example: data, It is typically

hacked using Merkle Tree.

In Merkle Tree, each non-leaf node, like the second tier above, is labeled with the

hash value of the child node (hierarchy 1) in this example, and finally, the tree is the

root- It is also good.


11

This root hash combines the nonce and the previous block with the first block in the

chain to form a blockchain.

4.3. Use in real life

4.3.1. Pay only if you have a smartphone

Attracoin will evolve to be able to use the biometric information of the user without

electronic equipment such as a computer if there is a smart phone in the future.

In other words, the user will implement a technology that enables settlement based

on strong security even with a smartphone alone.

To this end, the biometric information of the user and the wallet information are

linked and the biometric information of the user is recognized by the user who

requests the payment.

If the user recognizes his / her own biometric information and the coin amount that

can be paid in his / her wallet is larger than the requested amount of the user who

has requested the settlement, the settlement can be concluded.

4.3.2. Simple but complete security

The Attra is a fully secure wallet that not only protects your assets but also enables

you to make payments quick and fast.

We provide sufficient safety to survive recognition technology to encrypt the user's

life information and keep the key of its encryption.

In addition, since biometric information is recognized and a password duplication

safety device can be installed, it is safer and more convenient than any encryption

money in the world.


12

4.3.3. Inheritance of property

• Attracoin implements a cryptographic consensus algorithm that can safely inherit

its assets to the heir he wants, allowing the inheritance of the user's assets to the

inheritor easily, quickly, and securely.

To achieve this, we implement the following algorithm.

• All information can be kept in a place where the user wants with double encryption

algorithm

• The user enters his / her biometric information into the smartphone and opens the

Attra wallet.

• The user can input up to 10 pieces of his / her biometric information in case of an

accident and input only one or a few if desired.

• The user can store the paper wallet in separate storage or on paper.

• The user can enter his / her heir's biometric information and his / her wallet

information into his / her smart phone and store it together with the wallet

information.

• The user can set the conditions for inheritance. (For example, a few years after the

present, or a specified year)

• Allow the user to decide whether to start inheritance if it is the date of inheritance

or when opening the wallet.

• If the user has passed the year of inheritance,

5. Attracoin Specifications

Attracoin currency unit name: ATT

Coin type: PoS (Proof of Stake)

Hash algorithm: Scrypt

Block time: 60 seconds

Total Issued Coins: 2,100,000,000 ATT

ATTRA Coin uses the coin symbol ATT

The coin type was PoS (Proof of Stake) and the hashing algorithm was Scrypt.

The Scrypt algorithm is 30% to 40% more efficient than SHA256 and X11

algorithms.


13

When a block is created, it goes through a process called 'Hashing'. There are a

number of hash methods, but basically, a hash is what you think of as encrypting

any information. This is why bit coins and so on are called 'Crypto Currency'.

The block generation cycle was 60 seconds for fast coin transfer and transaction

processing

A total of 2.1 billion coins were issued.

In addition, users who hold more than 300 coins and make a decision to participate

will have a 6% interest was designed to be paid.

1. Beacon App card terminal

1.1. Beacon overview

A beacon is a wireless communication device that uses a Bluetooth 4.0-based

protocol to transmit signals to nearby devices. In other words, it's the next-

generation smart local area technology that allows you to locate a user within a

range of up to 100 meters and send messages or make mobile payments.

1.2. Beacon billing definition and installation, use agreement

Billing works with beacon-based technology. It is a simple structure that the payment

is made by touching the beacon connected to the existing force by the credit card

converted into the app card in the smartphone. With the simple idea of connecting a

beacon to an existing device, all cards can now be placed inside the smartphone.

Currently, we decided to pay for the app card with a beacon terminal, and about

20,000 monthly installments are being installed at the offline merchants.

1.3. Beacon Terminal Billing Process

Beacon payment is the next generation offline mobile payment solution using

Bluetooth 4.0 (BLE; Bluetooth Lower Energy). The process of payment of the credit

card entered into the mobile by the app card using the existing POS network is

completed in 0.8 seconds from the touch of the beacon to issuance of the receipt.

1.4. Beacon App Card Terminal Features

▶ Self-certified solution passed international standard adoption and security

supervision of the Financial Supervisory Service

▶ We are in the process of installing 200,000 beacons per year for offline

merchants through an agreement with domestic VAN company. I plan to gradually

install one million merchants

▶ Beacon terminal receives payment fee for each payment

▶ Remote settlement is possible even within 100M.
