Blockchain services at AWS

6. Amazon Quantum
Ledger Database (QLDB)
Fully managed ledger database with a
central trusted authority

7. 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
Challenges customers face

8. • 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
Amazon Quantum Ledger Database (QLDB)

9. How Amazon QLDB works

10. Amazon Managed Blockchain
Fully managed blockchain service, supporting both
Hyperledger Fabric and Ethereum frameworks

11. 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
Blockchain builds trust in a network

12. Complicated to
manage
Setup is hard Hard to scale Expensive
Challenges with existing blockchain solutions

13. • 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
Amazon Managed Blockchain

14. 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
How Amazon Managed Blockchain works

15. “Healthdirect Australia operates in a heavily regulated industry, and it is critical
that our compliance data is correct and auditable. With Amazon QLDB we
look forward to having a complete and verifiable history of every change in
our system, making it simple to audit when and how we arrived at our current
state. Regulatory compliance is fact of life for healthcare companies, and
Amazon QLDB enables us to easily track the controls we have in place and
understand how they have changed over time.”
—Bruce Haefele
General Manager, Technology, Healthdirect Australia

16. “Given our vast partner ecosystem, we are exploring the decentralization and immutable
tracking benefits of blockchain for potential applications in our insurance business. We
believe blockchain can improve the transparency and efficiency for stakeholders in these
networks to transact, while still maintaining an independently verifiable lineage of
activities. However, blockchain frameworks are complex and difficult to operate. With
Amazon Managed Blockchain, we can now easily create Hyperledger Fabric blockchain
networks to test and learn without worrying about managing the underlying
infrastructure, networking,
and software configuration.”
—Daniel Johnson
CTO and Head of Innovation, Guardian Life Insurance Company
