Summary

We have learned about the general concepts that underpin blockchains and reviewed the blockchain frameworks, libraries, and tools currently in development by the LF. Fabric presents a modular and extensible implementation of these general concepts. This design helps us to develop and operate private networks that provide trust to attract new participants, as well as sustaining the confidence of founding and existing participants, all while maintaining business benefits and value. We have also learned about the CAP theorem, which underpins the potential of blockchains, and about the new features included in Fabric since version 1.1.

In the next chapter, we will introduce the notion of a business network and the various concepts of which business networks are composed, including participants, assets, and others.
