Description

This curriculum spans the breadth of a multi-workshop program focused on securing blockchain systems, addressing the same technical depth and operational trade-offs encountered in enterprise advisory engagements on decentralized architecture, from threat modeling and consensus security to compliance and governance.

Mapping adversarial incentives in tokenomics-driven protocols to prioritize threat vectors
Integrating threat intelligence from on-chain anomaly detection systems into STRIDE assessments
Deciding scope boundaries between Layer 1 consensus risks and Layer 2 application risks
Documenting trust assumptions for oracles and cross-chain bridges in threat models
Validating threat model assumptions through historical exploit pattern analysis
Establishing review cycles for threat models synchronized with protocol upgrade timelines
