Tendermint/Cosmos: Many Chains, Many Tokens, One Ecosystem
- 1. Many Chains Many Tokens One Ecosystem Sunny Aggarwal
- 2. Who am I? Sunny Aggarwal Researcher with Tendermint Particular interests in Proof of Stake and Blockchain Interoperability Co-founder of Blockchain at Berkeley Previously worked at ConsenSys Teach a class at Berkeley on Switzerland
- 3. &
- 7. Tendermint Consensus Consistent Proof of Stake BFT Consensus Algorithm Can be used for both Public & Private Chains Instant Finality Highly Scalable Guarantees safety in asynchronous & liveness in weakly synchronous environments Basis for other Proof of Stake systems like Casper

- 15. An Internet of Blockchains Scalability Sovereignty PrivacyDiversity Security
- 16. Scalability Vertical vs Horizontal Scalability Vertical scalability through Proof of Stake, state channels, recursive snarks, etc Horizontal Scalability is achieved through many chains
- 17. Scalability Vertical Scalability Tendermint Core can get over 1000s of tx/second with over 100 validators on 5 different continents Research on how to make this even faster
- 18. Scalability Horizontal Scalability Application-based sharding is logical as it minimizes bottleneck You only have to be a full node for the applications you care about
- 19. Diversity Many applications can be built with Tendermint ABCI and Cosmos SDK with support for IBC
- 20. Diversity Implementations in Go, Rust, Python, C++, Javascript, Java, Ocaml, and Erlang Connect existing platforms like Ethereum and Chain to ABCI
- 21. Diversity Connect existing chains through pegged bridge zones
- 22. Application-Specific Chains Turing-Complete VMs are great for prototyping and some use cases Most production DApps doesn’t need to be on a Turing complete chain Flexibility can be achieved through governance
- 23. Application-Specific Chains Reduces attack surface Efficiency gains due less computational overhead Fine tune to optimize for your application
- 24. Interoperability Just because chains are separate, doesn’t mean they can’t talk to each other Use IBC, a 2-way on-chain light client protocol
- 25. Interoperability Applications/Smart Contracts on different chains can interact with each other Cosmos Hub allows for deep integration of token economies Token transfers, not just basic token swaps
- 26. Sovereignty Ethereum and Ethereum Classic cannot have the same validator set Private Chains can interoperate with Public Chains
- 27. Sovereignty Can use community power to achieve greater security than pure economic incentives alone Governance controlled by community
- 28. Pooled Security Optional pooled security through delegated consensus -> good way to bootstrap small public chains
- 29. One Ecosystem Features of different existing chains can be interoperated
- 32. Movement of Value Smart Contracts Bitcoin Transfer with Ethereum Smart Contracts
- 33. One Ecosystem Specific tokens do not have to be limited to a specific chain, but rather can be used across chains
- 35. One Ecosystem Smart contracts on one chain can call contracts on another
- 36. One Ecosystem Private chains can now interoperate with public chains
- 37. One Ecosystem
- 38. One Ecosystem
- 39. One Ecosystem
- 40. One Ecosystem Decentralized exchanges can be done with tokens across many different chains
