Why Decentralized Identifiers Are Changing the Future Internet?
去中心化身分識別(Decentralized Identifiers) 如何改變著未來的網路型態?

Level: 200-300, 中文演講
講師: Ryder Wang, Business Development Manager, AWS & Jserv Huang, Co-founder & CTO, BiiLabs

如果「資料」是數位世界的新「資產」,「身份」則是新「錢」。我們的資料是被挖掘的,每天都在 Google 或 Facebook 這樣的平台上被廣告商買進賣出。正是因為科技將我們的資料轉化成商品,新一波以隱私為核心的模式正在興起。去中心化身份識別 (DIDs, Decentralized Identifiers) 網路可以在既有的區塊鏈之上的第二層運作。去中心化身份識別,讓用戶無須透過核心權限就可以創造並控制他們的自身的身份資訊。分散式的基礎建設讓個人或組織得以在幾乎所有的區塊鏈、軟體供應商以及客戶端的實現去中心化的效果。

All rights reserved.S U M M I T Amazon Quantum Ledger Database (QLDB) (Preview) Fully managed ledger database Track and verify history of all changes made to your application’s data Maintains a sequenced record of all changes to your data, which cannot be deleted or modified; you have the ability to query and analyze the full history Immutable Uses cryptography to generate a secure output file of your data’s history Cryptographically verifiable Easy to use, letting you use familiar database capabilities like SQL APIs for querying the data Easy to useHighly scalable Executes 2–3X as many transactions as ledgers in common blockchain frameworks

  15. 15. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T What is immutability? 1 Tracy buys a car on Aug 3, 2013 DMV QLDB database will add Traci’s record 2 Tracy sells car to Ronnie on Sept 10, 2014 DMV QLDB database will add Ronnie’s record Journal Current stateDMV Scenario 3 Ronnie’s car gets in an accident and gets totaled DMV QLDB Database adds new row, called “delete” DELETE DATE: 09/02/2016 ID Manufacturer Model Year VIN Owner 1 Tesla Model S 2012 123456789 Traci Russell ID Manufacturer Model Year VIN Owner 1 Tesla Model S 2012 123456789 Ronnie Nash ID Manufacturer Model Year VIN Owner Built from ground-up in such a way that Journal cannot be modified or altered Entire change history is easily accessible
  16. 16. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T What is verifiability? Uses cryptography to create a digest of change history, acts as a proof You can use the digest to prove integrity of any transaction Cryptographic technique Digest Customer, Ronnie can verify the date Traci sold the car to him was indeed 7/16
  17. 17. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T Why do immutability and verifiability matter for customers? Reduce risk: ensure safeguarding of critical system-of-record applications where a data loss could potentially cost millions in lost dollars. Improve data tracking: helps you or any parties that have access to the system to quickly and accurately track data’s entire lineage, improving efficiency in tracking the source of issues (e.g., manufacturing defects, maintain supply network data hygiene) Auditability: helps reduce downtime caused due to audit and compliance issues, saving hundreds of productivity hours for your team Reduce implementation effort: Building immutability and verifiability is time consuming, complex, and expensive

  20. 20. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T Amazon Managed Blockchain Easily create and manage scalable blockchain networks Quickly create blockchain networks that span multiple AWS accounts. Easily add or remove members and monitor the network Fully managed Choice of Hyperledger Fabric or Ethereum Improves ReliabilityScalable and secure Easily scale your blockchain network as the usage grows. Also, Managed Blockchain secures your network certificates with KMS Choose the right framework for your needs, whether you are building a permissioned or public network Managed Blockchain improves the reliability of the “ordering service,” by replacing the default technology with QLDB. This improves durability.
  21. 21. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T Hyperledger Fabric and Ethereum benefits • Useful for a finite set of known users. • Well-suited for applications that require stringent privacy and permission controls with a known set of members • For example, a financial application where certain trade-related data is only shared with select banks and other members in the network don’t have access to the data Hyperledger Fabric • Useful for an infinite number of unknown users. • Well suited for highly distributed blockchain networks where transparency of data for all members is important • For example, a digital identity network comprising of farmers and government organization, where an infinite number of farmers can join the network and information regarding their land, crop yields etc. is shared across all members on the blockchain Ethereum

All rights reserved.S U M M I T On-Chain and Off-Chain Information w/ Blockchain 33 • On-Chain: Used for high priority tasks where data integrity and final authority are necessary. • Off-Chain: Used for frequent or low priority tasks where data integrity can be sacrificed in favor of mutability and processing speed. Depending on the blockchain, off-chain activity may be subsequently verified on-chain. • Both: Effective blockchain solutions leverage both on-chain and off- chain settlement to achieve positive outcomes.

All rights reserved.S U M M I T Decentralized Identifiers: Privacy on the Blockchain 34 • Decentralized Identifiers (“DID”) is a portable, secure, privacy-respecting, and entirely user- controlled online identity system • Control: People must have control over their identities, including control over who has access to what aspects of their identities. • Security and Integrity: People’s digital identities must be secure, accurate, and protected from unauthorized access, use, disclosure, or modification. • Portability and Sovereignty: People must be able to use their digital identities to identify themselves without seeking permission from, or being tied to, a service provider. People must be able to freely transfer their digital identities, and the digital identities must be “sovereign” - i.e., the identity cannot be taken away from the identified person.
