SoK: Tools for Game Theoretic Models of Security for Cryptocurrencies
[article]

arXiv
pre-print
Preserved Fulltext

Understanding how to incorporate this into the models used to design cryptocurrencies has motivated a large body of work, yet many open problems still exist and current systems rarely deal with incentive ...
One interesting aspect of cryptocurrencies is their explicit consideration of incentives at the protocol level. ...
Following the work presented above, Garay et al. propose Rational Protocol Design (RPD) [57] . In this setting, they define a game between the designer of the protocol D and the attacker A. ...

Naturally, this abstraction allows us to design fair protocols in a hybrid model in which parties have access to the F CR functionality, and is otherwise independent of the Bitcoin ecosystem. ...
Conceptually, our work provides the missing piece that simultaneously allows (1) designing protocols of fair secure computation that rely on Bitcoin (and not a trusted central bank), and (2) designing ...

In this work, we extract and analyze the core of the Bitcoin protocol, which we term the Bitcoin backbone, and prove two of its fundamental properties which we call common prefix and chain quality in the ...
Regarding BA, we observe that Nakamoto's suggestion falls short of solving it, and present a simple alternative which works assuming that the adversary's hashing power is bounded by 1/3. ...
Summary and Directions for Future Work In this paper we presented a formal treatment of the Bitcoin backbone, the protocol used at the core of Bitcoin's transaction ledger. ...
