Beyond Supra-Competitive Outcomes: Collusive Behaviour in Deep Reinforcement Learning for Optimal Execution Games
Christos Spyridon Koulouris, Carlo Campajola
In this paper, we extend earlier findings of supra-competitive outcomes in optimal-execution games by identifying a learned punitive mechanism that deters deviations and provides b…
Memory-Induced Supra-Competitive Outcomes Between Deep Reinforcement Learning Agents in Optimal Trade Execution
Christos Spyridon Koulouris, Carlo Campajola
In this paper, we investigate whether deep reinforcement-learning agents interacting in a shared optimal-execution environment can sustain supra-competitive outcomes, in the sense…
Concentration in Governance Control Across Decentralised Finance Protocols
Thomas Eisermann, Carlo Campajola, Claudio J. Tessone +1
Blockchain-based systems are frequently governed through tokens that grant their holders voting rights over core protocol functions and funds. The centralisation occurring in Decen…
Heterogeneity- and homophily-induced vulnerability of a P2P network formation model: the IOTA auto-peering protocol
Yu Gao, Carlo Campajola, Nicolo Vallarano +2
IOTA is a distributed ledger technology that relies on a peer-to-peer (P2P) network for communications. Recently an auto-peering algorithm was proposed to build connections among I…
Twisted by the Pools: Detection of Selfish Anomalies in Proof-of-Work Mining
Sheng-Nan Li, Carlo Campajola, Claudio J. Tessone
The core of many cryptocurrencies is the decentralised validation network operating on proof-of-work technology. In these systems, validation is done by so-called miners who can di…
The Evolution Of Centralisation on Cryptocurrency Platforms
Carlo Campajola, Raffaele Cristodaro, Francesco Maria De Collibus +3
More than ten years ago the blockchain was acclaimed as the solution to overcome centralised trusted third parties for online payments. Through the years the crypto-movement change…
MicroVelocity: rethinking the Velocity of Money for digital currencies
Carlo Campajola, Marco D'Errico, Claudio J. Tessone
We propose a novel framework to analyse the velocity of money in terms of the contribution (MicroVelocity) of each individual agent, and to uncover the distributional determinants…
The evolving liaisons between the transaction networks of Bitcoin and its price dynamics
Alexandre Bovet, Carlo Campajola, Francesco Mottes +4
Cryptocurrencies are distributed systems that allow exchanges of native tokens among participants, or the exchange of such tokens for fiat currencies in markets external to these p…
Network-based indicators of Bitcoin bubbles
Alexandre Bovet, Carlo Campajola, Jorge F. Lazo +7
The functioning of the cryptocurrency Bitcoin relies on the open availability of the entire history of its transactions. This makes it a particularly interesting socio-economic sys…
