Data-driven analysis of central bank digital currency (CBDC) projects drivers

no code implementations23 Feb 2021 Toshiko Matsui, Daniel Perez

In this paper, we use a variety of machine learning methods to quantify the extent to which economic and technological factors are predictive of the progression of Central Bank Digital Currencies (CBDC) within a country, using as our measure of this progression the CBDC project index (CBDCPI).

On $C^0$-persistent homology and trees

no code implementations4 Dec 2020 Daniel Perez

In this paper we give a metric construction of a tree which correctly identifies connected components of superlevel sets of $\mathbb{R}$-valued continuous functions $f$ on $X$ and show that it is possible to retrieve the $H_0$-persistent diagram from this tree.

Liquidations: DeFi on a Knife-edge

1 code implementation28 Sep 2020 Daniel Perez, Sam M. Werner, Jiahua Xu, Benjamin Livshits

We find that liquidators' efficiency has improved significantly over time, with currently over 70% of liquidable positions being immediately liquidated.

DeFi Protocols for Loanable Funds: Interest Rates, Liquidity and Market Efficiency

1 code implementation11 Jun 2020 Lewis Gudgeon, Sam M. Werner, Daniel Perez, William J. Knottenbelt

We coin the term *Protocols for Loanable Funds (PLFs)* to refer to protocols which establish distributed ledger-based markets for loanable funds.
