Initial Coin Offerings and Platform Building
AbstractIn a typical initial coin offering (ICO), an entrepreneur pre-sells digital tokens which will later serve as the medium of exchange on a peer-to-peer platform. We present a model rationalizing ICOs for launching such platforms: By transparently distributing tokens before the platform operation begins, an ICO overcomes later coordination failures during platform operation, induced by a cross-side network effect between transaction counterparties. Furthermore, a critical-mass requirement that arises from an endogenous same-side network effect during the ICO rationalizes several empirical patterns observed in ICO structures. Our model provides guidance for both regulators and practitioners to discern economically valuable ICOs.
An Equilibrium Valuation of Bitcoin and Decentralized Network Assets
AbstractWe address the valuation of bitcoins and other blockchain tokens in a new type of production economy: a decentralized financial network (DN). An identifying property of these assets is that contributors to the network trust (miners) are compensated in units of the same asset that are used by consumers of network applications, which we call unity. As a result, the overall production (hashrate) that affects network trust and the bitcoin price are jointly determined. We characterize the demand for bitcoins and the supply of resources that secure the network and show that the valuation of bitcoins can be obtained by solving a fixed-point problem and study its determinants. We show that the unity property induces price-hashrate spirals that amplify the price impact of demand and supply shocks vis-à-vis traditional assets.
