Helicopter Money and CBDCs: Are DLTs the perfect infrastructure for monetary policies in a time of crisis?
The nascent economic crisis is highlighting the need to rely on creative policy responses. Helicopter money appears to be one of the few untried monetary tool. Central Bank Digital Currencies (CBDCs) based on Distributed Ledger Technologies (DLTs) would provide the optimal infrastructure to implement such stimulus policy.
Practical solutions to save bitcoins applied to an identity system proposal
In a recent work by Augot et al. (2017), a scheme is proposed to build an identity system on top of the Bitcoin network. However, this proposal incurs very high costs since Bitcoin transactions require heavy fees. The current work introduces modifications to their scheme to make it more cost efficient while preserving its potential. Namely, we build on features of Bitcoin’s scripting language, which allows swapping coins between two compatible blockchains, and also on off-chain transactions.
An Equilibrium Model of the Market for Bitcoin Mining
We propose a model which uses the exchange rate of Bitcoin against the US dollar to predict the computing power of Bitcoin network. We show that free entry places an upper-bound on mining revenues and we devise a structural framework to measure its value. Calibrating the model’s parameters allows us to accurately forecast the evolution of the network computing power over time. We find that at most one third of seigniorage income was dissipated in electricity consumption. The model indicates that a slowdown in the rate of technological progress will significantly increase Bitcoin’s carbon footprint.
