The BitVM and BitVMX protocols, traditionally reliant on one-time signature (OTS) schemes like Lamport and Winternitz for program input signing, face significant storage overhead challenges that limit their practical use. In a groundbreaking improvement to these protocols, a new paper introduces the ESSPI method, which utilizes ECDSA/Schnorr signatures for BitVMX program input signing.

The discussion encapsulates the intricate challenges faced by developers in the realm of cryptocurrency, specifically focusing on the development and implementation of covenants and contracting primitives. A critical issue identified is the difficulty of attaining social consensus prior to achieving technical consensus.
