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

© 2019, Amazon Web Services, Inc. or its affiliates. All 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

© 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 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

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

© 2019, Amazon Web Services, Inc. or its affiliates. All 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

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
