Medical and psychosocial interventions,nt channels from the perspective of a Payment Service Provider (PSP). Given a set of transactions, we examine the optimal graph structure and fee assignment to maximize the PSP’s profit. A customer prefers to route transactions through the PSP’s network if the cheapest path from sender to receiver i

Our analysis demonstrates contradictions between these schemes – so clearly they cannot all be right – and also highlights what we feel is a more structural flaw of most of them, namely that they ignore alternatives

One approach to the problem of energy wastage is to find ways to build PoW schemes from valuable computational problems. This work proposes calibration of public key cryptographic systems as a suitable source of PoW puzzles. We describe

We show that an attacker needs only a small fraction (e.g., one millionth) of the resourc

We present an economic model that leverages Modern Portfolio Theory to predict a miner’s allocation over time using price data and inferred risk tolerance. The mod

In this paper we ask the natural question: can payments in routing networks be routed so as to avoid deadlocks altogether? Our results show that it is in general NP-complete to determine whether a
