Blockchain Incentives and Authentication

Unlike classical distributed systems, the security of blockchain-based systems like Bitcoin and Ethereum critically relies on correctly incentivizing their operators. Their design and analysis thus calls for novel tools and approaches. The talk will show how the incentive mechanisms expose new vulnerabilities and how they enable protocols that rely on the incentive structure. It will discuss recent results on bounds and resilient protocols.

The talk will also briefly present a novel formalization of the classical authentication problem. This formalization almost immediately reveals surprising results with practical implications to cryptocurrency client security.

The talk is self contained.
