A Crypto Yield Model for Staking Return
FinTechWe introduce a model that derives a metric to answer the question: what is the expected gain of a staker? We calculate the rewards as the staking return in a Proof-of-Stake (PoS) consensus context.

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices
Advanced Functional Materials, EarlyView.This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

A Novel Hybrid Sharing Economy Based Blokchain Model (Proof of Meet)
Journal of New Theory, 2020 This paper is the first part of the Proof of Meet (PoM) work. This part focuses on the need for the model and its system (roughly) rather than giving technical details.

Advanced Functional Materials, EarlyView.Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Consensus at a Turning Point: Analyzing Ethereum’s 2022 Migration From PoW to PoS
IEEE AccessThe development of blockchain consensus mechanisms has put sustainability, scalability, and efficiency first in the list of cryptocurrency studies. As Bitcoin still uses the energy-intensive Proof-of-Work (PoW) algorithm, Ethereum is in the process of ...
