Rejuvenation of wireless technology [li fi]
Li-Fi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. It was introduced by German physicist Harald Haas as a solution to the limited bandwidth of Wi-Fi networks. Li-Fi uses visible light communication and is capable of much faster data transmission speeds than Wi-Fi. It works by varying the rate at which LEDs flicker on and off to encode digital information in light pulses, which are then detected by a photodetector. Li-Fi offers advantages over Wi-Fi such as a larger usable bandwidth, more secure communications, and energy efficiency.

Urban agriculture
The document discusses the rapid urbanization occurring globally and the challenges cities face in becoming self-sustainable. It provides examples of how Shanghai, China has implemented urban agriculture by using 20% of city-administered land for agriculture and converting human waste into organic manure to grow food and deal with waste sustainably. In contrast, urban agriculture has not been incorporated into planning for Indian cities, and citizens there spend 70% of income on food while facing disease issues due to lack of sanitation infrastructure. The document argues for recognizing the importance of urban agriculture given population growth, increasing cities and decreasing farmers.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
