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
28. Loom Plasma Chain https://medium.com/loom-network/enabling-the-next-generation-of-decentralized-finance-with-multichain- collateralized-assets-c6008028f041
29. Plasma Chamber https://github.com/cryptoeconomicslab/plasma-chamber
30. OVM https://medium.com/cryptoeconomics-lab/a-gentle-guide-to-the-ovm-934035646942

32. Feature? with Interoperability
33. LINK Chain
34. LINK Chain • LINE Token Economyのねらい • https://logmi.jp/tech/articles/320359 • LINK Chainでうごくスマートコントラクト • https://speakerdeck.com/line_developers/smart-contract-on-link- chain • Introduction to LINEAR Network • https://speakerdeck.com/line_developers/linear-network- introduction-and-future • ETC. • https://link.network/notice/ • https://scan.link.network
35. Conclusion • Letʼs make own blockchain! • Dive into Interoperability world on Blockchain!
