Email:[email protected] challenges, we propose Solidus, a decentralized cryptocurrency based on permissionless Byzantine consensus. A core technique in Solidus is to use proof of work for leader election to adapt the Practical Byzantine Fault Tolerance (PBFT) protocol to a permissionless setting.

We also design Solidus to be incentive compatible and to mitigate. One of the greatest challenges faced by the cryptocurrency industry is its volatility and the fact that the cryptocurrency markets are, unlike mainstream currency markets, a social construct.

Intuition: mechanism design often relies on a party that you can trust for both correctness and privacy. A blockchain can be trusted for correctness, but not privacy. Hence, there are additional challenges in designing incentive-compatible mechanisms that can run on a blockchain. TODO: formalize all of this. BDoS is incentive-based – the attacker targets the system’s mechanism design and violates its incentive compatibility. Specifically, the attacker invests resources in order to incentivize rational miners to stop mining.

· Here, we employ the formal model developed by Eric Budish (), which examines both (i) the mining competition and (ii) incentive compatibility. It also provides the basis for discussing extensions, like proof-of-work versus proof-of-stake, an energy-frugal alternative to proof-of-work.

1 We include this aspect as well in the formal analysis. do not solve either of these issues, or they require Turing-complete language support, which severely limit their applicability.
