Paper of the Week:
This paper highlights that a private digital currency has significant implications for a corrupt emerging market; one with high volatility and a government that sets policies based on selfish interests rather than considering the welfare of citizens.
Citizens gain from the existence of the private digital currency through two channels: (i) private digital currencies offer diversification and (ii) private digital currencies serve as competition for local investments so that the existence of the private digital currency restrains monetary policy, thereby generating lower inflation.
Private digital currencies encourage local investments also operating through two channels: (i) a private digital currencies generally serve as a complement rather than as a substitute for local investments and (ii) the existence of the private digital currencies disciplines monetary policy by creating an alternative to local fiat.
Governments may gain from permitting the private digital currencies within the local economy because they extract revenue gains from citizens through taxation.
Governments permit the private digital currencies because of the additional revenue without regard to citizen welfare. This finding is particularly important because it implies that the previously discussed citizen welfare gains arise in equilibrium.
Summary: A traceable and linkable ring signature (with the security proofs) that realizes the regulatory function for users’ identities, and can prevent the malicious regulator from double spending, escaping from regulation, slandering users and forging signatures.

Summary: This paper forms an idea of how cryptographically-secure hardware obfuscation can be achieved by relying on the notion of Blockchain.
Summary: A protocol that improves the state-of-the-art HoneyBadgerBFT by reducing the asymptotic latency while matching the optimal communication complexity.

Summary: This work revisits zero-knowledge proofs in the discrete logarithm setting introducing almost no overhead. Next, a conceptually simple commit-and-prove argument is constructed for satisfiability of a set of quadratic equations.
Summary: A modified version of Ouroboros Praos where stakeholders can learn the slot number when they lose this information. Ouroboros Clepsydra satisfies the Common Prefix, Chain Growth and Chain Quality properties.

Summary: The core argument of this paper is that not only is it, in practice, impossible for public blockchains to govern successfully via exclusive reliance on their technical code – but also that, without legitimate and effective internal governance of public blockchain systems that rely on formalised and effective social mechanisms, they are unlikely to be taken up at scale as a tool for social co- ordination (ie governance by blockchain), and are thus likely to remain, at best, a marginal technology.

Summary: Determining whether cryptocurrency is a security and how to comply with applicable laws is a continuing area of development in federal and state securities regulation.
