DevStamp2018-Development Status and Future of ICON

  1. 1. ©2018 ICON Foundation ICON Introduction & Roadmap Interoperable platform for enterprise and DApp ecosystem
  2. 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"
  3. 3. ICON Strategy A platform to be chosen by users What values do we bring to the users? How is it changing their lives? Hyperconnect the World Build a community of communities based on the consensus to our governance and protocol
  4. 4. ICON Features BTP Blockchain Transmission Protocol transmits consensus between blockchains IISS ICON Incentive System based on Artificial Intelligence DEX Easy token exchange executed by Smart Contract On-chain
 Governance Propose and vote for ICON governance via Representation Channel ICON is the global inter-chain project which connects all private and public blockchains in the world. LOOPCHAIN Multi-channel supported blockchain technology
  5. 5. ICON Main-net Launched Main-net • 2018.1.25 - 1st transaction • 40 Representatives • 18 Exchanges • $93,922,554 market cap • 473,406,688 ICX circulations • 41th Cryptocurrencies • 141,654 Blocks • 14 Active contracts • 약 45,000 Addresses • 6 IRC2 tokens
  6. 6. ICON Network Rep Rep Citizen Citizen Citizen Citizen Citizen Citizen Citizen Light Client Citizen Citizen Light Client Citizen Light Client • Representatives produce and validate blocks. They are elected based on staking, contribution, and votes from ICONist. • Citizen synchronizes all block data from Representatives. • Light Client has block headers for verifying a given tx. Citizen Elected Anyone Rep Rep
  7. 7. Developer tools comparison ICON ETH EOS Smart Contract Development Python Solidity C/C++ SDK to call Smart Contract JS, JAVA, Python, Swift JS, JAVA, Python Node, Ruby JS, Python Dev tool to interface Node Tbears ( CLI ) Remix ( Web ) Cleos ( CLI ) Local Blockchain Environment Tbears GETH EOSIO Block Tracker
  8. 8. DEVELOPMENT ENVIRONMENT: T-Bears ▪ Programming Language: Python ▪ Developed locally, distributed to Store before testing ▪ Runs on Native Runtime Environment like Container (CPython) ▪ Composed of loopchain nodes deployed to Docker
 SCORE (Smart Contract On Reliable Environment) ▪ Dev tools for easy development of ICON’s Smart Contract(SCORE) and ICX Transaction ▪ Local development and local execution ▪ Available to deploy to testnet/mainnet after finishing the development [Use Cases] ▪ Smart Contract for token generation ▪ IIP, IRC token standard ▪ Smart ContractAddress ▪ Deployed to testnet and mainnet with contract codes onTx instead of ▪ Future VM support (Solidity, Java) T-bears
  9. 9. ICON Development Network on AWS marketplace AWS Cloud Formation • ICON Development Network will allow developers to easily run a private instance of the ICON Blockchain Network through AWS.
  10. 10. Blockchain for Enterprise (1) Exchanges Online banking certificate issued by 25 securities firms on blockchain CHAIN ID A campus crypto platform on a smart vending machine. Pilot service running at Sogang University and Postech University U-coin Pilot test with Kyobo Life Insurance, a major life insurance company in South Korea Automated Insurance Claim We understand the benefits, challenges, and opportunities in enterprises
  11. 11. Blockchain for Enterprise (2) • 관세청 - 블록체인 기반 개인통관 서비스 플랫폼 구축 시범사업 진행 중 • 정밀의료 병원정보 시스템 (P-HIS) 의료데이터 무결성 확보 기술 개발 진행 중 • 서울시 블록체인 시범 사업 진행 중 • 중앙선관위 차세대 선거 시스템 구축 진행 중 • 교보생명 스마트 보험금 청구 및 스마트 보장분석 사업 진행 중
  12. 12. What we’ve done & What we are doing Issues Done Doing Low performance (Scalability) BFT consensus, Multi-channel Parallel processing Tx, BTP(Blockchain Transfer Protocol),. 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
  13. 13. 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

 BTP Interoperability Connect heterogeneous blockchains and real world
  15. 15. !15 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) 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.
  16. 16. !16 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.
  17. 17. 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.
  18. 18. ICONest for ICO/STO User friendly token generation and management platform Create and set projects with simple information inputs without complex programming job Improved convenience for project managers by providing follow-up managements including refund and unlock Successful token sale Projects like Bluewhale/weBloc are successfully doing token sales via ICONest More diverse projects are further planned for token sales via ICONest in the future Token Launch Platform for ICON partners
  19. 19. ICON P-Rep Election : ICONSENSUS The Representatives of the ICON Network A P-Rep represents ICONists who do not belong to any specific Community. It is elected by evidencing its sufficient contribution to the ICON Network or by receiving sufficient delegations from other ICONists. A P-Rep also verifies transactions on the ICON Network, but unlike a C-Rep, it proposes and votes policies that maximize overall ICONist interests of the ICON Network. A P-Rep possesses the same authority and duty as a C-Rep.
