This Week in Security:
Summary: A new traceability attack on Monero and an analysis of the costs required for an attacker to conduct it.
Summary: A fast and provably secure proof-of-stake based blockchain protocol in open setting, which executes in a slot-synchronous network and resists a mildly adaptive adversary.
Authors: Peifang Ni*†‡, Hongda Li*†‡, Xianning Meng*†‡, and Dongxue Pan*†‡,
Summary: This paper discusses the notion of the decentralized trusted computing base as an extension of the TCB concept in trusted computing and explores how a decentralized TCB can be useful.
4. Paper Title: Another Look at ALGORAND.
Summary: This work shows that the claimed (proved) fork-free property in ALGORAND is not true and several assumptions are not realistic in practice.
Authors: Yongge Wang*,
Affiliations: * UNC Charlotte.
Summary: This paper proves that when the ratio between the resource power of the poorest and richest is close to 0, the upper bound of the probability that systems without a Sybil cost reach full decentralization is close to 0.
This Week in Privacy:
This Week in Scalability:
1. Paper Title: Atomic Commitment Across Blockchains.
Summary: An all-or-nothing atomic cross-Chain commitment protocol that uses an open Witness Network where refund events of smart contracts are modeled as conflicting events.

Summary: A reward system that can run on top of Proof-of-Stake blockchains where coins regenerate over time.
Affiliations: * University College London.
This Week in Tokenomics:
Summary: This work shows that the payouts from ASIC can be replicated by an integral of European call options, hence, the value of ASIC is increasing in the volatility of the cryptocurrency price.
Affiliations: * BUIDL, Ltd and † Stanford University.
Summary: Investors overreact to a firm’s first 8-K disclosure of a potential foray into Blockchain technology and that the overreaction is a function of the Bitcoin price bubble.
