An Optimal Probabilistic Protocol For Synchronous Byzantine Agreement

Feldman and Micali (STOC `88) present in a pioneering document a n-Bizantin Memorandum of Understanding that does not tolerate < n/3 of the malicious parties that rotate in constant expected cycles. Here we show a constant protocol expected for a certified Byzantine agreement, provided an honest majority (i.e. < n/2) and based solely on the existence of a secure signature card and a public key infrastructure (ICP). Combined with existing results, this gives the first permanent protocol expected for a secure calculation with an honest majority in a point-to-point network that supports only unique functions and a PKI. Our main technical tool – a new primitive that we are introducing, the moderate VSS – also provides a simpler proof of Feldman Micali`s result. We also show a simple technique for the sequential composition of protocols without simultaneous termination (something that is inherent in Byzantine contractual protocols with o (s) tricks for the case of t<n/2.

2022 International Temperate Reefs Symposium

The International Temperate Reefs Symposium will be held in Australia’s southern most state, Tasmania. The Symposium will be held in Tasmania’s capital, Hobart, from Monday 10th to Thursday 13th January 2022.

The ITRS is the premier conference for marine scientists with a focus on temperate hard-bottom habitats. The scope is broad and captures natural rocky reefs, man-made structures, and biogenic surfaces. Ecology is a key focus, but the meeting also caters for other scientific disciplines relevant to temperate reef biology including biogeochemistry, genetics, oceanography, remote sensing, biogeography and management, not to mention the vast array of interdisciplinary links.
