Shared
Information
Blockchain works with systems of record to integrate data
By Shirley S. Savage k Illustration by Greg Mably

istributed ledger
technology blockchain
links with existing systems
of record (SOR) application servers
and data managers. They share
information and assets securely
and immutably between
external parties.
It can be used to track the
lifecycle of a car, a financial
transaction or sources of food
ingredients. (Learn more about
how various industries are using
the technology in "The Business
of Blockchain" page 18.) The
transactions are very different from
those performed on mainframe
transactional systems in terms of
goals, timing and performance.
Simply stated, a blockchain
transaction is a contract
on blockchain, says Donna
Dillenberger, IBM Fellow. The goal
is to share data across multiple
enterprises in an auditable,
immutable way.
Blockchains today don't provide
millisecond response times, and a
single blockchain network won't
support billions of transactions
a day. However, a blockchain
transaction will keep all parties
on blockchain informed and will

D

provide a record for all parties.
The transaction is shared across
enterprises, so many views of the
immutable data are given.
In contrast, SOR transactional
systems on z Systems* use
transactional managers such
as IMS*, CICS* and DB2*.
Transactional managers process
billions of transactions a day
at millisecond speed with
high volume, high throughput
and high qualities of service,
Dillenberger notes. They ensure
each transaction has four
attributes: atomicity, consistency,
isolation and durability. When
transactions are committed
across all copies of that cluster
of transactional managers,
one view of the data exists or
it doesn't get committed at all,
she says. Typically, traditional
SORs don't support multiple live
copies in the manner blockchain
does-although some specialist
deployments of DB2 use
replication for high availability.

Blockchain Uses
Enterprises are looking to use
blockchain with existing SOR data
managers for two main reasons:

1.

2.

An enterprise wants to share SOR data with
external parties and leave a record of that
data exchange. "The record would include a
timestamp and list of what data was shared so the
record can be audited and the data is immutable,"
Dillenberger notes.
An event on the blockchain generates a need to
interact with a participant's SOR. That blockchain
event may trigger the start of a CICS transaction or
a DB2 procedure.
