Chalcedony and Childbirth: Precious and Semi-Precious Stones as Obstetrical Amulets **
It is also profitable to wear about them gemmes and precious stones, as the The custom of wearing or holding an amulet during pregnancy and childbirth is probably as ancient as the need for comfort and reassurance. For reasons not entirely clear, precious and semi-precious stones throughout recorded time have been considered to possess protective virtues."'8 The medical benefits ascribed to eac...
متن کاملByzantine Fireflies
This paper addresses the problem of synchronous beeping, as addressed by swarms of fireflies. We present Byzantine-resilient algorithms ensuring that the correct processes eventually beep synchronously despite a subset of nodes beeping asynchronously. We assume that n > 2f (n is the number of processes and f is the number of Byzantine processes) and that the initial state of the processes can b...
متن کاملMaking Byzantine Fault Tolerant Systems Tolerate Byzantine Faults
This paper argues for a new approach to building Byzantine fault tolerant systems. We observe that although recently developed BFT state machine replication protocols are quite fast, they don’t actually tolerate Byzantine faults very well: a single faulty client or server is capable of rendering PBFT, Q/U, HQ, and Zyzzyva virtually unusable. In this paper, we (1) demonstrate that existing proto...
متن کاملExtending Binary Byzantine Agreement to Multivalued Byzantine Agreement
The concern of this paper is a set of potentially faulty processes that engage in a distributed computation to agree on some piece of information. Each process enters the computation with an initial value. The computation returns a common result value to each correct process. If all correct processes begin the computation with identical initial values, then the result value equals the initial v...
متن کاملOptimistic Asynchronous Byzantine Agreement
Agreement problems are a fundamental building block for constructing reliable distributed systems. While robust and eÆcient protocols exist in the crash-failure setting, protocols resilient against a Byzantine adversary tend to have problems with either eÆciency or security. This paper proposes an optimistic approach to the Byzantine agreement problem, combining the eÆciency of fully synchronou...
