Unlocking Liquid Restaking - Measuring Worst-Case Stake Loss, Cross-Contagion Risk, and LTV in LRTfi Networks

Let’s develop a framework around how Liquid Restaking Token (LRT) providers could measure and relay the worst-case stake loss $R_\psi(C)$ for different validators, calculate cross-contagion risk (which is important when validators are interconnected or share market risks), and how this could feed into an overall system like Nucleus to provide mo...

Quantifying Decentralization and Safety of Social Consensus in Blockchains

Introduction Social consensus is often treated like a magic fix for safety faults in blockchain networks, especially in the fast-paced conversations on Crypto Twitter (CT). But if history has taught us anything—whether it’s the bitter small block vs. big block debates or the Ethereum split after the DAO fork—it’s that social consensus is anythi...
