2. Trust in key institutions and governments has been steadily declining
over the past two decades. Economic crises, fake news and global
pandemics bring a need for transparency, security and
provability of information.
Business today is no longer based on personal interactions. We
are being asked to put faith in email addresses and phone calls. In a
globally-connected world, business records need to be immutable,
auditable, thus trusted.
Permissioned Blockchains aka Distributed Ledger
Technology brings with it the promise of changing the way we interact,
do business and receive information. Everyone in the network is now able
to verify claims others are making.

3. Permissioned Blockchains in Action is filled with insight, tips and tricks for
building and deploying permissioned blockchain systems. You’ll learn
vital developer skills for securing your blockchains against threats,
writing smart contracts on permissioned blockchains, and picking the
blockchain stack that’s best for your project.

4. Permissioned Blockchains in Action is a
technology-agnostic guide to creating
innovative applications using DLTs.
Permissioned Blockchains in Action is not a
manual. What you will gain is a true
understanding of why we use blockchains
and how to choose the right technology for
your problem
By the time you’re done reading, you’ll be
ready to take the plunge into mapping real-
world relations to blockchain applications.
