 - **Slow block propagation and validation on signet**: Measurements showing that slowly-validating blocks on Bitcoin's Signet testnet propagate approximately 160 times slower than normal blocks. Median validation took around 20 seconds compared to 176 milliseconds for standard blocks, highlighting real-world impact of BIP 54's targeted issues.

 - **Inertial Mining**: A proposed mining protocol that produces Nakamoto's intended single longest chain outcome while constituting a true game-theoretic equilibrium. The authors show that neither selfish mining nor any other deviation is profitable for miners controlling less than half the network's power.
