Web3/blockchain security is another place where math demand is high, supply is thin, and OSS can meaningfully replace or amplify scarce experts. The difference vs PQC is that here the pain is economic + protocol correctness, not regulation (yet).
Below is a long, structured OSS opportunity list for cybersecurity math in Web3, optimized for high-demand / low-supply roles.
I’ll organize it by who you’d be replacing or assisting, then list tools, keywords, and why demand is structural.
Core assumption (what “math” means in Web3 security)
Pure-math-level demand here centers on:
Game theory & mechanism design
Formal verification / logic
Probability & adversarial modeling
Cryptography correctness
Economic security proofs
Compositional reasoning
Most exploits are not bugs — they are math failures.
High-demand / low-supply Web3 security roles (today)
Scarce roles you can partially replace:
Protocol security researcher
Smart-contract formal verification engineer
Cryptoeconomic designer
MEV / adversarial game theorist
Consensus protocol analyst
Cross-chain security specialist
Zero-knowledge proof engineer
Auditor with economic modeling skills
Each of these supports dozens of protocols → huge leverage for OSS.

Highest-leverage OSS wedges (if you must pick 3)
If your goal is maximum impact per engineer, start with:
Cryptoeconomic simulation + security budget calculator
Invariant/spec templates + invariant mining
Threat-model generator + audit evidence pack
These replace thinking bottlenecks, not just tooling gaps.
Key meta-insight (important)
Web3 security failures are math failures disguised as software bugs.
That’s why:
audits scale poorly
exploits repeat
talent is scarce
OSS leverage is enormous
