Constant-deposit multiparty lotteries on Bitcoin

Massimo Bartoletti and Roberto Zunino

Abstract

An active research trend is to exploit the consensus mechanism of cryptocurrencies to secure the execution of distributed applications. In particular, some recent works have proposed fair lotteries which work on Bitcoin. These protocols, however, require a deposit from each player which grows quadratically with the number of players. We propose a fair lottery on Bitcoin which only requires a constant deposit.

Note: Added proofs, and improved discussion on related work.
