ICON Introduction
Interoperable platform for enterprise and DApp ecosystem
ICON Vision
A rhizome has no beginning or end; it is always in the
middle, between things, interbeing, intermezzo. The
tree is filiation, but the rhizome is alliance, uniquely
alliance. The tree imposes the verb "to be" but the fabric
of the rhizome is the conjunction, "and ... and ...and..."This
conjunction carries enough force to shake and uproot the
verb "to be." Where are you going? Where are you coming
from? What are you heading for? These are totally
useless questions.
- Mille Plateaux, Gilles Deleuze & Felix Guattari
"Hyperconnect the world"
https://tracker.icon.foundation/block/0

IISS (ICON Incentive Scoring System),
Transaction Fee system
At the core, ICON rewards those who contribute to the ecosystem
Delegated Proof of Contribution
• P-Rep is elected by delegation of
stake of ICX.
• Incentive system that allocates block
rewards based on level of
contribution (Block producing, Tx,
EEP)
Reasonable dApp usage Fee Incentive System for Developers
• Fee can be shared by Smart
Contract operators and users
• Smart contract operators can save
fee by staking ICX tokens
• Incentive will be distributed for DApp
developers and ICON contributors
according to IISS(ICON Incentive
Score System)
• IISS focus on the developers who
can make transactions
IISS
Parallel Processing of Tx
Solution for Scalability
• Transaction is supposed be executed sequentially. —> Most of transactions are independent each other.
• Sharing, side-chain, plasma, …
Parallel Execution of Tx
• Transaction execution time is one of major bottle-neck of blockchain.
• Independent transactions can be executed in parallel.
• Executor Manager can determine the independence of transaction
by “from”, “to”, and explicit decorator in smart contract.
BTP: What is Interoperability?
Inter-blockchain value transfer
• Transfer of coins or tokens from a blockchain to another
• Decentralized Exchange(DEX)
Interoperability of services between blockchains
• Execute and share results of smart contracts on
different blockchains
• Interoperate enterprise blockchain services on public
blockchain
Provide Blockchain Scalability
• Horizontal Scalability Solutions
BTP: Possible Use Cases of Interoperability Solutions
Connect with private blockchains
• KYC for ICO using Chain ID
• Buy stocks with ICX
• Transfer financial goods in ICON network
• Buy cryptokitties using Smilegate in-game currencies
• Claim insurance with ICX
• Hedge financial contracts using ICON smart contract
Connect with public blockchains
• Send ICO token to other blockchains
• Exchange tokens in between blockchain networks
BTP: What is Blockchain Transfer Protocol?
BTP Overview
• Nexus coordinates BTP requests and response with proof.
• All interchain requests are processed atomically
• C-Rep is responsible for managing BTP messages
between ICON and heterogeneous block chains

Decentralized Identifier (DIDs)
Public Blockchain
1. Reg DIDIssuer 2. Reg DIDHolder
3. Request Claim
4. Issue Verifiable Claim
5. Save Verifiable
6. Present Verifiable Claim
8. Connect to
7. Verify (Check Signature)
https://w3c-ccg.github.io/did-spec/
Decentralized Identifiers (DIDs) are a new type of identifier for verifiable, "self-sovereign" digital identity. DIDs are fully under the control of the DID
subject, independent from any centralized registry, identity provider, or certificate authority.

Decentralized Identifier (DID)
Blockchain DID 인증 실생활 인증 온라인 인증
1단계
사용자가 개인 증명 자료와
요청 정보를 Issuer에게 제출
사용자가 신분증 발급 신청서와
확인 소명 자료를 주민센터에 제출
사용자가 공인인증서 발급기관 또는 등록 기관(은행/증
권사) 방문 후 주민등록증 제시
2단계
Issuer는 증명 자료와 요청 정보를 기반으로
Verifiable Claim 발급
주민센터는 제출 서류로 신분증 발급 등록기관에서 공인인증서 발급 신청
3단계 사용자 Verifiable Claim 저장 (사용자 소유) 사용자 신분증 수령(본인 소유) 공인인증서 온라인 발급 및 저장
4단계
사용자는 온라인 마트에서 주류 구매 시
Verifiable Claim 제출
사용자는 주류 구매 시 마트 직원에게 신분증 제시
온라인에서 공인인증서와 함께 주민등록번호 제시

(공인인증서 본인확인 기능 활용)
DID 인증
• Issuer 선택 가능하고, 소유한 Verifiable Claim들 중 하나를 선택 제출할 수 있도록 설계되어 탈 중앙화 가능 .
• 개인 정보를 저장하지 않음.
DEX (Decentralized Exchanges)
The Bancor protocol enables built-in price discovery and a liquidity mechanism for tokens on smart contract blockchains. These “smart
tokens” hold one or more other tokens in reserve and enable any party to instantly purchase or liquidate the smart token in exchange for
any of its reserve tokens, directly through the smart token’s contract, at a continuously calculated price, according to a formula which
balances buy and sell volumes.
Solution to liquidity problem
• Bancor 알고리즘을 이용하여, 토큰/코인 간의 자동화되고 탈중앙화된 거래 방법 제공.
• 거래 대상이 필요 없다.
• 저렴한 거래 비용. 자산 도난 방지.
• 리스크가 낮은 지속적인 유동성.
• 예측 가능한 토큰 가격

ICONest for ICO/STO
ICONest 1.0, User friendly token generation and management
platform
Create and set projects with simple information inputs without complex
programming job
Projects like Bluewhale/weBloc are successfully doing token sales via
ICONest
ICONest 2.0, a platform for users to easily STO without a detailed
understanding of security token protocols, smart contracts and
compliance
The ICON STO platform abstracts the details of protocols, smart
contracts, and complications, and allows users to easily issue, manage
and trade securities tokens by providing Layer 1 to Layer 4
Token Launch Platform for ICON partners
Secret Sharing (Vault)
사용자의 Secret Data(Private Key)를 사용자가 직접 지정한 복수의 Storage에 분산 보관하고, 복구할 수 있는 서비스를 제공
• Secret을 복구할 수 있는 정보들을(Shared Clues) 각 Storage에 분산(Secret Sharing) 저장함
• Secret Data는 Master Phrase나 Account의 Private Key 등이 될 수 있음
• Device의 분실 등과 같이 소유하고 있는 정보가 없는 상황에서도 각 Storage에 대한 권한 확인 절차를 통하여 Secret Data를
복구할 수 있음
• 분산된 정보를 보관하고 있는 Storage 중 일부 Storage의 보관 정보만으로 Secret Data를 복구
• 일부 Storage의 담합으로 인한 Secret Data 유출을 방지
• 사용자는 Shared Clues를 암호화하여 각 Storage에 전달
• Shared Clues의 암호화에 사용된 키는 사용자가 지정한 Master Storage(예, Vault Storage)에 보관
Blockchain에서의 Private Key관리 매우 중요한 이슈
• Private Key를 분실하면, 자산의 소유를 증명할 수 없음.
Secret Sharing (Vault)
ICON Vote
Smart Contract로 구성된 전자투표 Protocol
• 특징
- 개표 시점 이전의 표의 내용에 대한 기밀성 보장.
- 개표 이후 정확한 투표 결과 산출 및 투표내용 공개.
• 방법
• 현재 투표 주제 입력으로 Voting contract를 activation함.
• n명의 관리자(rep)들의 합의를 통해 암호화키 생성
• Voter들은 자신의 투표를 암호화 하여 Contract에 전송
• n명 중 t명의 관리자의 합의로 복호화키 생성
• 투표 종료 이후 모든 투표 복호환하여 표를 집계함.
Blockchain의 비가역적 특성을 이용한 투표는 굉장히 유용하나, 현 제도와 맞지 않은 부분이 있음.
• 개표 이전에 결과 공개 금지.
• 비밀투표

  • 2. ICON Vision A rhizome has no beginning or end; it is always in the middle, between things, interbeing, intermezzo. The tree is filiation, but the rhizome is alliance, uniquely alliance. The tree imposes the verb "to be" but the fabric of the rhizome is the conjunction, "and ... and ...and..."This conjunction carries enough force to shake and uproot the verb "to be." Where are you going? Where are you coming from? What are you heading for? These are totally useless questions. - Mille Plateaux, Gilles Deleuze & Felix Guattari "Hyperconnect the world" https://tracker.icon.foundation/block/0

Unfavorable development environment SCORE (python based smart contract) with tbears, AWS marketplace (to support blockchain in private/ local network) More Samples, documents, technical supports, … Oracle problem Private/Enterprise blockchains Connecting Private blockchain via BTP. Lack of killer dApps ICONest (ICO platform) Decentralized ID, STO, DEX, Vault, Secret Vote. Governance White Paper, Yellow Paper On-chain governance IISS (ICON Incentive Scoring System), Transaction Fee system
  • 23. At the core, ICON rewards those who contribute to the ecosystem Delegated Proof of Contribution • P-Rep is elected by delegation of stake of ICX. • Incentive system that allocates block rewards based on level of contribution (Block producing, Tx, EEP) Reasonable dApp usage Fee Incentive System for Developers • Fee can be shared by Smart Contract operators and users • Smart contract operators can save fee by staking ICX tokens • Incentive will be distributed for DApp developers and ICON contributors according to IISS(ICON Incentive Score System) • IISS focus on the developers who can make transactions IISS
  • 24. Parallel Processing of Tx Solution for Scalability • Transaction is supposed be executed sequentially. —> Most of transactions are independent each other. • Sharing, side-chain, plasma, … Parallel Execution of Tx • Transaction execution time is one of major bottle-neck of blockchain. • Independent transactions can be executed in parallel. • Executor Manager can determine the independence of transaction by “from”, “to”, and explicit decorator in smart contract.
  • 25. BTP: What is Interoperability? Inter-blockchain value transfer • Transfer of coins or tokens from a blockchain to another • Decentralized Exchange(DEX) Interoperability of services between blockchains • Execute and share results of smart contracts on different blockchains • Interoperate enterprise blockchain services on public blockchain Provide Blockchain Scalability • Horizontal Scalability Solutions

  • 29. !29 Decentralized Identifier (DID) Issuer Holder Verifier Decentralized Identifier (DIDs) Public Blockchain 1. Reg DIDIssuer 2. Reg DIDHolder 3. Request Claim 4. Issue Verifiable Claim 5. Save Verifiable 6. Present Verifiable Claim 8. Connect to 7. Verify (Check Signature) https://w3c-ccg.github.io/did-spec/ Decentralized Identifiers (DIDs) are a new type of identifier for verifiable, "self-sovereign" digital identity. DIDs are fully under the control of the DID subject, independent from any centralized registry, identity provider, or certificate authority.
  • 30. !30 Decentralized Identifier (DID) Blockchain DID 인증 실생활 인증 온라인 인증 1단계 사용자가 개인 증명 자료와 요청 정보를 Issuer에게 제출 사용자가 신분증 발급 신청서와 확인 소명 자료를 주민센터에 제출 사용자가 공인인증서 발급기관 또는 등록 기관(은행/증 권사) 방문 후 주민등록증 제시 2단계 Issuer는 증명 자료와 요청 정보를 기반으로 Verifiable Claim 발급 주민센터는 제출 서류로 신분증 발급 등록기관에서 공인인증서 발급 신청 3단계 사용자 Verifiable Claim 저장 (사용자 소유) 사용자 신분증 수령(본인 소유) 공인인증서 온라인 발급 및 저장 4단계 사용자는 온라인 마트에서 주류 구매 시 Verifiable Claim 제출 사용자는 주류 구매 시 마트 직원에게 신분증 제시 온라인에서 공인인증서와 함께 주민등록번호 제시
 (공인인증서 본인확인 기능 활용) DID 인증 • Issuer 선택 가능하고, 소유한 Verifiable Claim들 중 하나를 선택 제출할 수 있도록 설계되어 탈 중앙화 가능 . • 개인 정보를 저장하지 않음.
  • 31. DEX (Decentralized Exchanges) The Bancor protocol enables built-in price discovery and a liquidity mechanism for tokens on smart contract blockchains. These “smart tokens” hold one or more other tokens in reserve and enable any party to instantly purchase or liquidate the smart token in exchange for any of its reserve tokens, directly through the smart token’s contract, at a continuously calculated price, according to a formula which balances buy and sell volumes. Solution to liquidity problem • Bancor 알고리즘을 이용하여, 토큰/코인 간의 자동화되고 탈중앙화된 거래 방법 제공. • 거래 대상이 필요 없다. • 저렴한 거래 비용. 자산 도난 방지. • 리스크가 낮은 지속적인 유동성. • 예측 가능한 토큰 가격 DEX (Smart Contract) Seller Buyer ICX ETH ETH ICX
  • 32. ICONest for ICO/STO ICONest 1.0, User friendly token generation and management platform Create and set projects with simple information inputs without complex programming job Projects like Bluewhale/weBloc are successfully doing token sales via ICONest ICONest 2.0, a platform for users to easily STO without a detailed understanding of security token protocols, smart contracts and compliance The ICON STO platform abstracts the details of protocols, smart contracts, and complications, and allows users to easily issue, manage and trade securities tokens by providing Layer 1 to Layer 4 Token Launch Platform for ICON partners
  • 33. Secret Sharing (Vault) 사용자의 Secret Data(Private Key)를 사용자가 직접 지정한 복수의 Storage에 분산 보관하고, 복구할 수 있는 서비스를 제공 • Secret을 복구할 수 있는 정보들을(Shared Clues) 각 Storage에 분산(Secret Sharing) 저장함 • Secret Data는 Master Phrase나 Account의 Private Key 등이 될 수 있음 • Device의 분실 등과 같이 소유하고 있는 정보가 없는 상황에서도 각 Storage에 대한 권한 확인 절차를 통하여 Secret Data를 복구할 수 있음 • 분산된 정보를 보관하고 있는 Storage 중 일부 Storage의 보관 정보만으로 Secret Data를 복구 • 일부 Storage의 담합으로 인한 Secret Data 유출을 방지 • 사용자는 Shared Clues를 암호화하여 각 Storage에 전달 • Shared Clues의 암호화에 사용된 키는 사용자가 지정한 Master Storage(예, Vault Storage)에 보관 Blockchain에서의 Private Key관리 매우 중요한 이슈 • Private Key를 분실하면, 자산의 소유를 증명할 수 없음.
  • 35. ICON Vote Smart Contract로 구성된 전자투표 Protocol • 특징 - 개표 시점 이전의 표의 내용에 대한 기밀성 보장. - 개표 이후 정확한 투표 결과 산출 및 투표내용 공개. • 방법 • 현재 투표 주제 입력으로 Voting contract를 activation함. • n명의 관리자(rep)들의 합의를 통해 암호화키 생성 • Voter들은 자신의 투표를 암호화 하여 Contract에 전송 • n명 중 t명의 관리자의 합의로 복호화키 생성 • 투표 종료 이후 모든 투표 복호환하여 표를 집계함. Blockchain의 비가역적 특성을 이용한 투표는 굉장히 유용하나, 현 제도와 맞지 않은 부분이 있음. • 개표 이전에 결과 공개 금지. • 비밀투표
