The document discusses Amazon Managed Blockchain, a fully managed service that makes it easy to create and manage scalable blockchain networks. It allows customers to set up blockchain networks using popular open-source frameworks like Hyperledger Fabric and Ethereum. Amazon Managed Blockchain handles complex tasks like provisioning hardware and managing the networks so customers don't have to deal with these challenges. It also integrates with other AWS services and provides reliability, security, low costs and ease of use. An example is provided of how Nestle uses it for supply chain management.

4. Amazon Quantum Ledger Database (Amazon QLDB)
for centralized trust
Amazon QLDB
Journal
Append-only, immutable
journal stores a sequenced,
cryptographically verifiable entry
of each change made; changes are
chained together as blocks,
e.g., credits and debits
Cryptographically verify the
change history of your data
Current state and
indexed history
Stores the current value and
historical state of your data,
e.g., the current value of a bank
account and its history
Access complete history
of changes to your data
Application data
Credit and debit transactions,
insurance claim history,
supply chain asset tracking,
vehicle records, and more
 Immutable

 SQL-like query
 Serializable ACID txns

6. Blockchain builds trust in a network
Eliminates the need for central authority in business networks
with three main components:
Distributed ledger, consensus mechanism, and smart contracts

7. Difficult to create blockchain networks
• Provisioning hardware
• Complex to configure software and networking
• Need to secure certificates and access control
• Monitoring and management of complex systems
• Adding and removing members
• Governing the network
• Scaling performance as the transaction rate grows

8. What is Amazon Managed Blockchain
Amazon Managed Blockchain is a fully managed
service that makes it easy to create and manage
scalable blockchain networks using popular
open source frameworks: Hyperledger Fabric
and Ethereum

9. Managed Blockchain features
Fully managed

AWS services

10. 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 peer nodes
Transact with
other members on
the network

Basic components of a Hyperledger Fabric blockchain
running on Managed Blockchain

12. Reliable and scalable
Ordering service
• Core component of a Fabric network to guarantee delivery and order
of transactions
• Open-source production grade networks use Apache Kafka for this component
• Managed Blockchain uses Amazon QLDB technology, increasing durability
and reliability
Certificate authority
• Open source uses a “soft” HSM
• Managed Blockchain uses AWS Key Management Service (AMS KMS) to secure
the certificate authority service
Augmented Hyperledger Fabric

13. Who owns the network?
Distributed ownership
Networks are decentralized
and can remain active even
after the initial creator leaves
Members vote to invite and
remove members and
configure network rules
Each member pays for
their resources

14. Voting and proposals to govern the network
• Networks are decentralized and can remain active
even after the initial creator leaves
• Members vote on who to invite and remove
• Network voting rules to determine how a proposal is
approved

15. Network
• Pay-as-you-go with
no up-front costs
• Per-second billing
• Each member pays for their
own resources and the data
written to the network
• Standard data transfer rates

• Test and small production networks
• bc.t3.small and bc.t3.medium
• Ordering service provisioned has
lower transaction throughput and
availability than that in a Standard
