rights reserved. S U M M I T Challenges customers face Building Ledgers with traditional databases Difficult to manage and scale Impossible to verify Error prone and incomplete Resource intensive Blockchain approaches Designed for a different purpose Adds unnecessary complexity

rights reserved. S U M M I T Amazon Quantum Ledger Database (QLDB) 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 use Highly scalable Executes 2–3X as many transactions as ledgers in common blockchain frameworks

rights reserved. S U M M I T What is immutability? 1 Tracy buys a car on Aug 3, 2013 2 Tracy sells car to Ronnie on Sept 10, 2014 DMV QLDB database will add Ronnie’s record Journal Current state DMV 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 DMV QLDB database will add Traci’s record

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

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 in a traditional way is time consuming, complex, and expensive

Banking & finance Keeping track of transactions, trades and accounts

rights reserved. S U M M I T Blockchain builds trust in a network Eliminates the need for central authority in business networks Three main components: distributed ledger, consensus mechanism, and “smart contract” execution environment Together these elements allow two parties to transact with one another by ensuring other parties consent to the transaction and record the transaction. This provides immutability and trust

rights reserved. S U M M I T Challenges with existing blockchain solutions Complicated to manage Setup is hard Hard to scale Expensive

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 reliability Scalable 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

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

S U M M I T How Amazon Managed Blockchain works Amazon Managed Blockchain Create a network Choose an open source blockchain framework, set up a new blockchain network and your membership in your AWS account with just a few clicks Invite members Invite other AWS accounts to join the network Add nodes Create and configure blockchain peer nodes that store a copy of the distributed ledger Deploy applications Create and deploy decentralized applications to your network through your per nodes. Transact with other members on the network

rights reserved. S U M M I T Why do customers care about implementing a blockchain? Many existing business networks rely on central authorities, which can be inefficient, expensive, and require time-consuming auditing A consortium could achieve better outcomes by sharing information, but cannot agree on how data can be securely and fairly shared Multiple organizations need to independently verify transaction history and need a single, up to date, accurate view of data Business logic among multiple organizations could be simplified through automation Asset transfers require an expensive and inefficient escrow

rights reserved. S U M M I T Common customer use cases Trade finance Improve efficiency in cross- border payments Retailers Improve ROI of customer loyalty programs Healthcare Doctors and hospital networks share patient data securely Track and trace Improve transparency for goods movement across distributed suppliers + Many more…

S U M M I T Summary: helping customers identify the right AWS blockchain service Owned by a single, trusted authority Addresses core need of a immutable and verifiable transactional log It’s a database, so its fast, as it doesn’t require consent from members Amazon QLDB Amazon Managed Blockchain No single owner of the ledger. Joint ownership by multiple parties Addresses core need of enabling multiple parties to transact transparently and with trust with each other Removes intermediaries when a group of members needs to transact. So it makes business processes more efficient Ownership Addresses Need Key Benefit
