The z Systems
Advantage
Besides secure containers on
z Systems, IBM provides hardware accelerators for hashing,
encryption and elliptic curve
digital signatures used to sign
blockchain transactions.
IBM also makes it possible for
users to shadow their existing
business process data on blockchain. Blockchain can be run in a
VM next to an existing z Systems
business process, such as DB2*,
CICS*, IMS* and the Transaction
Processing Facility.
Another advantage of running
blockchain on z Systems is
HiperSockets*, an accelerated network communication that provides 7x more
throughput and 82 percent
faster response time to speed
communications. HiperSockets
is useful for enterprises that
want to provide a blockchain
service to their partners. A user
can run multiple blockchain
peers on a z Systems server as
separate VMs, LPARs or Docker

"IBM is advancing blockchain by
providing a permissioned, secure
implementation of the blockchain."
-Donna Dillenberger, IBM Fellow, z Systems

containers. "You can have optimized communication between
the blockchain peers using
HiperSockets," Dillenberger says.
Blockchain can augment
existing systems. If you
want to share data from your
existing business processes
with partners, blockchain is a
good choice, she says. You can
choose to share selected fields
that would help you and your
business partners optimize
business interactions. Such

sharing wouldn't slow down or otherwise affect
existing business processes.
Not every business application is suitable for
blockchain, however. It's not a good option for a
high-performance workload, such as a transaction
manager or a database that requires millisecond
response times. "Blockchain is good to optimize
business processes that currently take days or
weeks," Dillenberger says.

Regaining Data Ownership
Blockchain isn't just for business-it's beneficial
for medical records too. If a patient goes to a new
hospital or doctor, the patient could give the new
provider an appropriate encryption key to access
her records. Patients could have different encryption keys for various medical or dental records.
"It's a way for people to own their data again,"
Dillenberger says.
Blockchain could be used to record ownership and
maintenance of houses and vehicles. The blockchain
data would add value to the sale as potential buyers
could see immutable maintenance records of the
house or vehicle they wish to buy and know what
repairs or improvements have been made.
If you're interested in trying blockchain, IBM offers
no-charge access to a VM and a blockchain Docker
image so you can take blockchain for a test drive.
Further, IBM offers assistance to any IBM client
looking to write blockchain applications.
Blockchain can simplify many business processes
and add speed, transparency and security at the
same time. IBM recognizes its value and is working
to make it a useful tool for business.
