The Sum of Its Parts: Analysis of Federated Byzantine Agreement Systems. (arXiv:2002.08101v4 [cs.DC] UPDATED)

Federated Byzantine Agreement Systems (FBASs) are a fascinating new paradigm
in the context of consensus protocols. Originally proposed for powering the
Stellar payment network, FBASs can instantiate Byzantine quorum systems without
requiring out-of-band agreement on a common set of validators; every node is
free to decide for itself with whom it requires agreement. Sybil-resistant and
yet energy-efficient consensus protocols can therefore be built upon FBASs, and
the "decentrality" possible with the FBAS paradigm might be sufficient to
reduce the use …
