Transcript

1. The intersection between open-source and blockchain : Trust and Consensus Charles Jhong August 2 2020
2. About Me - Hey I’m Charles Jhong - A golang developer - Working at AMIS - Wallet service backend - Bitcoin/Omni integration - Motorcycle enthusiast 2
3. Agenda - What is blockchain? - What does blockchain to do with open-source? - Philosophy in common - AMIS’s open-sourced project 3
4. What is blockchain? 4
5. Bitcoin - A decentralized ledger maintained by a distributed system - What does “decentralized” mean ? - Who are those “miners” ? - With an innovative economy model, a currency system without bank and government was born - It’s designed as a ledger, but just a ledger 5
6. Ethereum - A distributed computing platform featuring smart contract - With a turing complete programming language called Solidity - Smart contracts (aka Dapps) will be executed in an isolated environment called EVM 6
7. Ethereum - Each dapp has its own storage and logic - Not only a ledger system anymore - Blockchain becomes a stack of protocols - There’s no need to build a new chain for most developer - Layer 1 focus on security, scaling while layer 2 focus on applications and business 7
8. Ethereum 8
9. Ethereum 9
10. What does blockchain to do with open-source? 10
11. Trust - the core of a financial system 11
12. No source, no trust - Without government, people trust blockchain system is because they trust cryptography algorithms, game theory and the consistency of Dapps execution result - In order to make sure these characteristics preserved, revealing it’s source code is inevitable 12
13. Fundamental ones - Cryptography library - Client node - To convince those early adaptors - More developers and users, more secure 13
14. Dapp needs transparency - There’s no trust in a decentralized black box - What if somebody deploy another Dapp instance using my open-sourced code? - Copyright? - Business model - Maintenance 14
15. Consensus - Consensus algorithm - If parties in community are not in agreement of certain change, alternative (forked) chains may emerge 15
16. Philosophies in common 16
17. Collaboration - Open source is an efficient way of people collaborate with each other - Miners are incented to do good things together so the system can be trust 17
18. Freedom - No censorship - Self-sovereignty (Your assets, your control) - An internet of value 18
19. Open and Transparency - Open finance - Voting - On-chain governance - DAO : Decentralized Autonomous Organization 19
20. AMIS’s open-source project 20
21. Alice - A HTSS library written in golang - Hierarchical Threshold Signature - Shorter signature and better privacy than multisig - Improve accountability of TSS 21
22. General multisig 22
23. TSS & HTSS 23 Threshold Signature : Hierarchical TSS
24. Alice - Reviewed and Audited by Kudelski Security - Github : https://github.com/getamis/alice - AMIS Medium : https://medium.com/getamis 24
25. Vishwakarma - Terraform modules for deploying self-hosting kubernetes cluster - Infrastructure-as-code (IaC) - Versioning infrastructure - Reusable module - With default and customized ASG - Github : https://github.com/getamis/vishwakarma 25
