 By decoupling transaction processing from consensus, Leios allows for more
 efficient and continuous resource usage (eg, CPU and bandwidth). Instead of
 experiencing short bursts of network load when blocks are fully created,
 validated, and diffused, Leios introduces two core components to facilitate this
 decoupling:
 
-## Input blocks (IBs)

 - Validators (stakeholders or miners) bundle transactions into lightweight IBs
