1. Blockchain and Cryptocurrency

1) What is blockchain?

Blockchain, known to the world through a paper published by Satoshi Nakamoto*, is a technology in which all users (nodes) participating

in the network distribute and store data such as transactions. A set of distributed and stored data is called a block. A consensus is

reached and a block is generated by a consensus algorithm.**

2) Future of Blockchain and Cryptocurrency Market

It is virtually impossible for a malicious user to forge or alter the block information because all the users who participate in the block

generation verify the information recorded in the block through the consensus algorithm. Therefore, the cryptocurrency of the

blockchain can perform monetary functions.

* Smart contracts: Self-running code that writes the rules and processes

The information recorded in the Bitcoin block is a simple cryptocurrency transaction. However, blockchain is actively developing

technologies such as smart contracts*. Today's blockchain is becoming a platform for developing and operating applications that go

beyond just acting as a currency.

DApp plays an important role in the blockchain ecosystem. DApp will be an opportunity for users to participate in the blockchain and to

expand the scale of the blockchain platform. Currently, most blockchain platforms' DApps are only used in limited areas such as gaming

and gambling. However, LEDGIS has the advantage that practical DApps of various fields can participate.

LEDGIS Enterprise case 3. Renewable Energy Blockchain Project

The renewable energy blockchain project records the REC production of solar operators and issues them as tokens.

The issued tokens will be sold as dividend tokens. Electricity sales will be registered on the blockchain, the revenue generated will be

issued to token investors.

< Concept of REC CHAIN 1: Power Generation Information on Blockchain >

< Concept of REC CHAIN 2: REC-based Token Issuance and Investment Flow >

“REC LEDGIS”

Profits generated by LEDGIS resource pool and

energy project

③ IBCT sells REC in KPX(Korea Power Exchange)

④ Direct remittance of payouts from KPX to generator's account

⑤ Direct deposit from generators’ account to IBCT account

⑥ After confirmation of deposit, IBCT announces the token purchase price to token holders.

•IBCT purchases tokens from holders at the price announced.

※ The profit model of this project offers the opportunity of liquidation for

generators, even before the sale of REC using blockchain technology.

The profit from the gap between the REC token face value and the REC

sale price is shared among REC token issuers, investors and IBCT.

① Power generation contractor contracts power brokerage business with IBCT

② IBCT provides technical support for token issuance so that the generators, owners of REC can issue and sell REC tokens

•The generators can issue and distribute tokens through IBCT with monthly payment for blockchain platform lease.

•The face value of token issuance is set after consultation.ex) Set an average of 70% of the lowest trading price on the previous trading day.

•Generators may hold or sell the issued token to investors at face

2) Model 2: REX

What is REX?

REX (Resource Exchange) is a resource leasing market where DApps can utilize resources by utilizing LED coins owned by users. Users

can deposit LED coins and get fixed profits through REX. Deposited LED coins can be returned without loss and you can earn profits

based on the amount of LED coins deposited.

REX: How it works (An example)

User A deposits 1,000 LED in REX. After depositing, User A receives a deposit certificate to guarantee the 1,000 LED

STEP 1 : Join REX

1000 LED Deposit CertificateUser A

REX

REX

User A can deposit an LED coin in REX, issue a deposit certificate after 4 days (after 96 hours) and receive the LED coin back.

The returned LED coin is the initial deposit plus any additional revenue from the interest income structure of STEP2.

STEP 3: LED claimed as deposit certificate

User A Deposit Certificate

REX 1000 LED + a

A large amount of coins, such as a portion of the annual coin issuance, will enter REX. Additional revenue other than deposits will be

distributed evenly to users participating in REX. User A who participated in REX through STEP 1 earns additional income in addition to

the 1,000 LEDs deposited.
