Since the 2008 economic crisis, network research has become increasingly prominent in the world of finance. The complex interrelations and financial interdependencies formed among financial market participants have proved to be critical in times of crisis. In this paper, we explore the network...

Spanish Abstract: Este artículo analiza algunos elementos característicos del mercado OTC de valores colombiano. Usando métricas del análisis de redes e información de las transacciones de títulos de deuda pública, compara el mercado OTC de valores con sus mercados organizados. Los...

Network analysis has been applied to identify systemically important financial institutions after the 2008 financial crisis. Such applications have stressed the importance of centrality within the too-connected-to-fail concept.Yet, despite their well-known importance for financial stability,...

We propose a new methodology to assess intermediaries’ substitutability in financial networks featuring higher-order structures (credit intermediation chains). We represent the financial network as a hyperstructure and each credit intermediation chain as a hyperedge. This approach allows us to...

Most digital platforms are inherently versatile partly because their software code can be modified, but primarily because they are designed as open-ended modular stacks whose affordances increase with the variety of functionalities provided by the upper layers, without needing to rewire or...

Bitcoin is digital energy. This is part metaphor, part description. It is part explanation, part prophecy. It is part engineering, part finance. The digital energy that is Bitcoin is not mechanical, chemical, or electrical. It is the same “stuff” that saves you time when you draw on a store...

By design, the Bitcoin protocol has a low throughput. The Lightning Network (LN) is a layer-two solution built to increase throughput by cryptographically securing commitments to transactions and only occasionally converting cumulative balances into on-chain transactions. LN channels enable...

For seven cryptocurrencies—Bitcoin (BTC), Ether (ETH), Cardano (ADA), Ripple (XRP), Solana (SOL), Litecoin (LTC), and Dogecoin (DOGE)—we compute the efficient set of portfolios for daily returns for the period January 2020 to September 2022. The paper reports the “background” statistics,...

Just as network effects can dramatically increase value through positive feedback, value can be lost as networks shrink due to competition or incompatibility. In the instance of cryptocurrency as a network and with Metcalfe's Law as the methodology, we illustrate by numerical example that...

In this paper we provide a mathematical derivation that links traditional time-value-of-money concepts to Metcalfe value, and use Bitcoin, Facebook as numerical examples of the proof. There is compelling evidence that suggests that the growth and price of bitcoin and other cryptocurrencies are...
