This chapter will cover the crypto-legalism issues pertaining to the rule of code-based blockchain regulation, demonstrating—how the characteristics of the code embedded in the blockchain architecture formulate to the notion of ‘crypto-legalism’? By defining the concept of crypto-legalism and its characteristics, the present chapter endeavors to elucidate congruities between legalism within the legal domain and technological normativity, aiming to seamlessly incorporate the cushioning effects of the former into the latter, where it aims to answer a secondary question—do the code rules in blockchain architecture, that is, the rule of code, meet the rule of law standards that can render them legitimate?
