Today, Amazon Web Services, Inc. (AWS), an Amazon.com company
(NASDAQ: AMZN), announced the general availability of Amazon
Quantum Ledger Database (QLDB), a fully managed service that
provides a high-performance, immutable, and cryptographically
verifiable ledger for applications that need a central, trusted
authority to provide a permanent and complete record of
transactions across industries like retail, finance, manufacturing,
insurance, and human resources. Amazon QLDB offers familiar
database capabilities that make it easy to use, and its
document-oriented data model is flexible, enabling customers to
store structured and unstructured data in the ledger. There are no
upfront commitments to use Amazon QLDB, and customers pay for what
they use. To get started with Amazon QLDB visit

Customers looking to implement blockchain technologies are
typically trying to accomplish one of two things. Some customers
want the immutable and verifiable record of transactions provided
by a ledger, however they also want to allow multiple parties to
transact, execute contracts, and share data anonymously, without
the need for a trusted central authority (e.g. transferring reward
points across a network of vendors, or processing transactions that
concern a number of different trade and logistics companies).
Today, Amazon Web Services offers customers Amazon Managed
Blockchain for this use case. There are other customers who have
applications that need a centralized ledger to record all changes
or transactions and maintain an immutable record of these changes
(e.g. tracing the movement of an item through a supply chain
network, tracking the history of credits and debits in banking
transactions, or validating incidents filed against an insurance
claim). This ledger is owned by a single trusted entity and is
shared with any number of organizations that are working together.
To do this today, customers can use relational databases, or they
can use the ledger technology in one of the open source blockchain
frameworks. Neither solution is optimal. Relational databases
aren’t built for immutable, cryptographically verifiable ledger
entries, so customers must build audit trails and audit logs. And,
there is no way for customers to verify that unintended changes
were not made to the data. Using the ledger in a blockchain
framework may give customers an immutable history of data changes,
but comes at the cost of the heavy lifting to set up a full
blockchain network with at least two nodes and all of the
associated access control configuration. Because there are limited
database Application Programming Interfaces (APIs) within the
blockchain frameworks it is also challenging to create tables,
index, and query data. Finally, blockchain frameworks are
decentralized and require consensus from members in the network
before committing new transactions to the shared ledger, which
significantly slows ledger performance.
Amazon QLDB is a new class of database that provides a
high-performance, immutable, and cryptographically verifiable
ledger that customers can use to build applications that act as a
system of record, where multiple parties are transacting with a
centralized, trusted entity. Amazon QLDB removes the need to build
complex audit functionality into a relational database or rely on
the ledger capabilities of a blockchain framework. Amazon QLDB uses
an immutable transactional log, known as a journal, which tracks
each and every application data change and maintains a complete and
verifiable history of changes over time. All transactions must
comply with atomicity, consistency isolation, and durability (ACID)
to be logged in the journal, and cannot be deleted or modified. All
changes are cryptographically chained and verifiable in a history
that customers can analyze using familiar SQL queries. Amazon QLDB
is serverless, so customers don’t have to provision capacity or
configure read and write limits. They simply create a ledger,
define tables, and Amazon QLDB will automatically scale to support
application demands, and customers pay only for the reads, writes,
and storage they use. And, unlike the ledgers in common blockchain
frameworks, Amazon QLDB does not require distributed consensus, so
it can execute two to three times as many transactions in the same
time as common blockchain frameworks.
“For years, AWS has been using an internal version of Amazon
QLDB to store configuration data for some of its most critical
systems, and has benefitted from being able to view an immutable
history of changes. Over time, our customers have asked us for the
same ledger capability, and a way to verify that the integrity of
their data is intact,” said Shawn Bice, VP, Databases, Amazon Web
Services, Inc. “Today, we are proud to announce Amazon QLDB,
offering customers a fully managed service that provides the same
ledger capabilities, along with the ability to cryptographically
verify data integrity. We are excited to see customers streamline
their operations and enhance their customer and partner experiences
by using Amazon QLDB to do things like keep track of credit and
debit transactions across customer bank accounts and reconcile data
between supply chain systems to track the complete manufacturing
history of a product.”
Amazon QLDB is available today in US East (Ohio), US East (N.
Virginia), US West (Oregon), Asia Pacific (Tokyo), and EU
(Ireland), with additional regions coming soon.
Splunk Inc. helps organizations ask questions, get answers, take
actions, and achieve business outcomes from their data. “Data is a
strategic asset that organizations rely upon to operate and
succeed,” said Nate McKervey, head of Blockchain and DLT, Splunk.
“It is that organizations can trust their data as it is dispersed
across teams and the cloud, but not every use case requires a
decentralized ledger. We are excited about the potential for Amazon
QLDB to provide a way to trust and verify the integrity of data
without the complexity of operating a blockchain network.”
Klarna Bank is one of Europe’s largest banks, providing payment
solutions to 60 million consumers across 130,000 merchants in 14
countries. “We’re building our own banking platform from the ground
up. We need this platform to be scalable, compliance-friendly,
cost-effective, and have real-time capabilities,” said Ziad
Sawalha, VP Engineering of Core Banking, Klarna Bank. “To support
this platform, we needed a cryptographically-verifiable and
immutable transaction log at the core. We experimented with
blockchain earlier this year and realized that a decentralized
ledger did not really meet our needs as it was too complicated to
operate and not sufficiently performant. With the release of Amazon
QLDB we can leverage the AWS’s investment in a centralized ledger
database to solve that problem, allowing us to focus our engineers
on other, customer-centric aspects of the platform.”
Bank of Yokohama, a member of Concordia Financial Group, is the
largest regional bank in Japan. “While designing and building
applications to support banking operations, we need to ensure that
the general ledger is up-to-date with the record of a client’s
attribution and deposit balances. In addition to that, we need to
retain the logs of our general ledger, including all of its
transaction activity and modification history,” said Takahisa
Kawahara, Group Leader, ICT Planning & Promotion Department,
Bank of Yokohama. “Amazon QLDB allows us to automatically save the
modification history and verify the consistency of the log. The
solution reduces human error while keeping the development cost
low. We look forward to leveraging Amazon QLDB for core banking
operations.”
Driver and Vehicle Licensing Agency (DVLA) is a central
government agency responsible for the registration and licensing of
over 48 million drivers in Great Britain, and over 40 million
vehicles in the UK. “The registers we maintain are critical to a

we handle data is vital,” said Matt Lewis, Chief Architect, DVLA.
“Amazon QLDB has the potential to bring significant benefits to the
way we process information, and we’re excited to be exploring how
this emerging technology further supports our services.”
Zilliant’s SaaS solutions are powered by advanced technologies
in order to enable B2B companies to transform data into actionable

customers to manage their product price lists and customer
agreements with their clients,” said Shams Chauthani, CTO and SVP
R&D, Zilliant. “Given the sensitive nature of the information
being managed by these products, it is critical to maintain
verifiable audit logs of the changes to prices and agreement terms.
In some cases, due to compliance requirements, these audit logs
must be immutable. We are excited to be exploring Amazon QLDB as a
way to seamlessly capture cryptographically verifiable audit logs
that can stand up to the strict compliance requirements of our
customers.”
