In cryptography and number theory, TWIRL (The Weizmann Institute Relation Locator) is a hypothetical hardware device designed to speed up the sieving step of the general number field sieve integer factorization algorithm. During the sieving step, the algorithm searches for numbers with a certain mathematical relationship. In distributed factoring projects, this is the step that is parallelized to a large number of processors.

TWIRL is still a hypothetical device - it has not yet been built. However, its designers, Adi Shamir and Eran Tromer, estimate that if TWIRL were built, it would be able to factor 1024-bit numbers in one year at the cost of "a few dozen million US dollars". TWIRL could therefore have enormous repercussions in cryptography and computer security - many high-security systems still use 1024-bit RSA keys, which TWIRL would be able to break in a reasonable amount of time and for reasonable costs.

Review:
This book is very clear. It explains most of the fundamentals of discrete mathematics, including logic, combinatorics, graph theory, probability, number theory, cryptography, and more. Things are clearly explained, and students are taught the basics of proof writing. Proof templates give the reader a skeleton for different proofs (such as direct, contradiction, induction, contrapositive, etc.). A great book!

TimeAlly is a DApp which refers to a suite of protocols that define distribution of Newly Released Era Swap (ES) Tokens in a decentralized way. TimeAlly uses Ethereum Virtual Machine (“EVM”), which can execute code of arbitrary algorithmic complexity following standard cryptography with no downtime and keeping all created objects safe from modifying. Every transaction triggered by users are recorded transparently & irreversibly in block confirmation so that old transactions are preserved forever for all to see. TimeAlly is an open source application & can work even without any web interface.

Quadratic Voting (QV) aims to bring the efficiency of markets to collective decision making by pricing rather than rationing votes. The proposal has attracted substantial interest and controversy in economics, law, philosophy and beyond. The goal of this conference is to evaluate the promise of Quadratic Voting and to stimulate research on QV from a broad range of perspectives. Leading scholars from disciplines ranging from classics to cryptography will present their work on diverse issues related to QV, including the history of the ideas behind it, practical implementation for market research surveys, objections to the use of money in politics and how QV might have averted political disasters in history. The conference papers will be published in a special issue of Public Choice in 2017, following up on a parallel special issue forty years prior on the use of the Vickrey-Clarke-Groves mechanism for collective decisions.
