  1. Blockchain into Interoperability and LINK Chain Blockchain EXE #19 at

    2019-09-11 LINE Corporation Blockchain Lab; Toshimasa Nasu
  2. Interoperability?

  3. Interoperability on Blockchain Exchange Blockchain A Blockchain B

  4. Interoperability on Blockchain Exchange Bitcoin Ethereum

  5. Why?

  6. Blockchain Trilemma Decentralization Security Scalability

  7. Solutions of Scalability • Hard fork • Shading • Sidechain

    • State Channel • Etc.
  8. Sidechain Mainchain node node node node Sidechain node node node

    node Sidechain node node node node
  9. Bitcoin + Liquid Bitcoin node node Liquid node node •

    Liquid • First product for Bitcoin node node node node
  10. Ethereum + Plasma Ethereum node node Plasma node node •

    Plasma • MVP • Plasma Cash • Plasma XT • Plasma Debit • Plasma Snapp • Plasma Bridge • More VP • Etc. • Loom Plasma Chain • (Zombie Chain) • Plasma Chamber • Etc. node node node node
  11. https://plasma.group/ • Plasma Chain: • Sidechain • OVM: • State

    Channel with Sidechain
  12. By the way... • EOS • Steem • TRON •

    Cosmos • Polkadot • Etc.
  13. Cosmos Cosmos Hub node node Zone node node Zone node

    node node node node node node node
  14. Cosmos + Ethereum Peg Zone node node Ethereum node node

    node node node node Cosmos Hub node node node node
  15. Cosmos Network https://coinsavage.com/content/2019/04/5-differences-between-cosmos-polkadot/ Peg Zone

  16. Polkadot Relay Chain node node Parachain node node Parachain node

    node node node node node node node
  17. Polkadot + Ethereum Bridge Chain node node Ethereum node node

    Relay Chain node node node node node node node node
  18. Polkadot 2.0 Network https://medium.com/polkadot-network/polkadot-the-foundation-of-a-new-internet-e8800ec81c7

  19. Specialty of Cosmos and Polkadot • Oriented Interoperability • Can

    make own blockchain • Cosmos SDK + Tendermint • Cosmos Network • Binance Chain • Terra • Substrate • Polkadot • Kusama
  20. Specialty of Cosmos and Polkadot • But, there is a

    difference • Cosmos: Peg Validation • Polkadot: Merge Validation
  21. Cosmos: Peg Validation Cosmos Hub no de no de Zone

    no de no de no de no de no de no de TX A Block A TX A Block B TX B TX B 1 3 2 4
  22. Polkadot: Merge Validation Relay Chain no de no de Parachain

    no de no de no de no de no de no de TX Block A TX Block B TX Block A TX 1 2 4 3
  23. Debate Cosmos and Polkadot • https://www.youtube.com/watch?v=VNcIMrDjawQ

  24. Sidechain? Interoperability? • Scalability Solution • Mainnet + Sidechain and

    etc. (=Layer2 Solutions) • Mainnet with Interoperability
  25. In addition…

  26. Ethereum 2.0 https://docs.google.com/presentation/d/1G5UZdEL71XAkU5B2v- TC3lmGaRIu2P6QSeF8m3wg6MU/edit#slide=id.g3c326bb661_0_58

  27. Loom Plasma Chain https://medium.com/loom-network/plasmachain-gamechain-socialchain-the-loom-network-universe- expounded-5c672617a333

  32. Feature? with Interoperability

  33. LINK Chain

  34. LINK Chain • LINE Token Economyのねらい • https://logmi.jp/tech/articles/320359 • LINK

  35. Conclusion • Letʼs make own blockchain! • Dive into Interoperability
