As interest rates increased, bond prices fell, directly affecting the value of banks’ fixed-income securities holdings. This depreciation of assets put a strain on banks’ profitability and financial stability. Banks with long-term bonds were hit particularly hard, emphasizing the importance of prudent risk management and portfolio diversification.

The crisis also exposed the inherent risk of bank runs in the fractional reserve system. Despite the presence of deposit insurance, panic-induced withdrawals led to a loss of confidence in the banking sector. The limitations of deposit insurance schemes became apparent, revealing the potential for systemic risk in the financial system.

This wake-up call underscores the need for innovation and alternative business models in the banking industry. As we grapple with the consequences of the 2023 U.S. banking crisis, it’s time to explore groundbreaking solutions that can address the challenges faced by traditional banking systems. Could blockchain technology and decentralized finance (DeFi) be the answer? The potential benefits include improved interest rate management, reduced bank run risks, enhanced transparency, and greater financial inclusion.

We must carefully assess the lessons learned from the 2023 banking crisis and consider how innovative solutions like blockchain finance can transform the industry. Stay tuned for our next post, where we’ll dive into the potential of blockchain finance as a new business model for banks.

We are pleased to announce that Crypto Review Vol. 3 was published on 17 June, 2021. Articles in this issue cover DeFi, digital assets and digital finance, Bitcoin valuation methods, and blockchain solutions for loyalty programs.

The increasing price volatility of cryptocurrency markets has aroused heated discussions both inside and outside the crypto community, drawing scathing criticism especially from many who have doubts about cryptocurrency. All those who are concerned about digital currencies are now looking for an answer to this wave of violent market fluctuations. Let’s have a look at the message from our editorial board discussing the core behind Bitcoin.

Hope you find the articles in Crypto Review Vol. 3 informative. Stay healthy and safe!

In this special issue, we present eight articles distilled from invited speeches during the

 2020 Virtual Crypto Forum: The Role of Cryptocurrency – Blockchain in the Post – Pandemic World.

During the past year, significant developments have occurred in the cryptocurrency field. Decentralized ecosystems, such as Bitcoin, successfully endured great market volatility caused by the pandemic, economic recession, and political uncertainty. Meanwhile, a new wave of crypto financing experiment, DeFi, is flourishing across many blockchain platforms. Government backed central bank digital currency (CBDC) projects have gained increasing support in mainstream monetary discussions.

On the flip side, regulators have started to tame the “wild west” development of crypto industry, followed by private litigations against various parties accused of illegal activities. We believe this is just the beginning of an enduring struggle.

Therefore, we present the authors’ perspectives without a subjective position. We believe market competition will naturally select the most adaptive idea in the long run.

This pandemic changed our view on globalization from every angle: the cross-border movement of people, product, capital, and information; the effectiveness of post-cold war institution and US dollar as its reserve currency; the explosion of “fake news” and the scarcity of truth; the struggle between individual liberty and governments’ interest in mass surveillance. A post-pandemic new world must address all these issues to a certain degree. And cryptocurrency, as apolitical money and decentralized ledger, has a role in every single one of them.

The articles in this issue cover digital assets, market analysis for post-halving Bitcoin, the implication of consensus in Bitcoin’s scarcity, and a deep analysis of Bitcoin’s blockchain data.

We hope you find these articles informative. Stay safe!

        It began in the winter of 2018, when mainstream opinions voiced the end of cryptocurrency. We believed otherwise. Thanks to nearly one year’s effort and contribution from our colleagues, friends, and supporters, Crypto Review is created to bring you cryptocurrency focused, forward looking content with long term impact from both industry and academic perspective.

        Austrian School economist and Nobel Laureate Friedrich August von Hayek published “The Denationalization of Money” in 1976, five years after U.S. President Richard Nixon unilaterally ended the international convertibility of the US dollar to gold and replaced the Bretton Woods system with pure fiat monetary regime. In his book, Professor Hayek envisioned a world with competing currencies issued by private businesses, and individuals choose the best ones to use. It is a world of the Separation of Money and State.

        Professor Hayek passed away in 1992, too soon to witness his proposal being gradually realized by Cypherpunk programmers, not economists, in the age of Internet. The pursuit of a digital, peer-to-peer, non-sovereign monetary system utilizing cryptography began with David Chaum’s “Blind Signatures for Untraceable Payments” in 1983. Many projects in the 1990s, including b-money, Bitgold, and Hashcash, did not result in an actual cryptocurrency but nevertheless tested the essential technical building blocks. Finally, our world was forever changed on January 3^rd, 2009, when a mysterious genius called Satoshi Nakamoto combined public-key cryptography, distributed nodes, blockchain structure, and proof-of-work in a functioning way and mined Bitcoin’s genesis block.

        Ten years later, Bitcoin is currently serving as a borderless, censorship-free, apolitical, digital medium of exchange and store of value for whoever has access to the internet. As of September 2019, the existing supply of Bitcoin has a market capitalization of near 200 billion US dollar. We believe it is still very early, thus create Crypto Review to glimpse into the future.

        Cryptocurrency is an interdisciplinary subject that depends on the knowledge of mathematics, computer science, game theory, and economics. It may impose great technological, economic, and political impact to our world. Crypto Review will provide full-spectrum coverage on cryptocurrency to our readers and focus on topics that have potential long-term impact.

        In this inaugural issue, we bring you the following six articles:

        “Global (Crypto) Currencies and Currency Competition” is authored by scholars associated with Becker Friedman Institute for Economics at The University of Chicago. It theoretically explores the dynamic of currency competition introduced by cryptocurrencies. It derives profound implications on monetary policy and the foreign exchange market.

        “Impacts of Consensus Algorithms in Cryptocurrency: A Theoretical Analysis of PoW versus PoS in Ethereum” compares the current Proof-of-Work consensus mechanism with the proposed Proof-of-Stake mechanism. It suggests that neither can dominate. The choice between PoW and PoS is a trade-off and should depends on Ethereum community’s preference.

        “Swimming with Fishes and Sharks: Beneath the Surface of Queue-based Ethereum Mining Pools” investigates the reward distribution scheme of Ethereum mining pool and finds a vulnerability of the queue-based reward scheme. Its result can be applied to other Proof-of-Work based cryptocurrencies that utilize mining pools to coordinate hash power.

        “Making Tokens Governable” provides a practitioner’s perspective about reconciling crypto tokens and the regulatory environment. It suggests the positive feedbacks between crypto industry and regulators may lead to a more decentralized regulatory regime in the future.

        “Cryptocurrency as Directly Investable Protocol” takes the decentralized crypto ecosystem as a new method of financing projects, such as open source software, that have difficulty in raising fund through the traditional capital market. It also analyzes the benefit vs cost of funding a project through decentralized cryptocurrency.

        We also provide an English version of “Conceptual Prototype of Chinese Digital Fiat Currency”, which may has served as the guidance for the upcoming central bank digital currency (CBDC). Although many voices in the crypto community do not consider CBDC as real cryptocurrency, we believe serious discussion about this subject is beneficial to the development of crypto industry as it is part of the grand currency competition game.

        We hope you will find these articles informative and inspiring. We believe cryptocurrency will provide humanity a future with greater liberty and prosperity.
