In the world of decentralised finance (DeFi), blockchain, and cryptocurrency, maximalism has a negative connotation, as it takes a similar philosophy to extremes. Maximalists believe that their concept, construct, and technology are superior to the point where others are inferior and unnecessary (for example, Bitcoin or Ethereum maximalists believe that their respective blockchains and cryptocurrencies are the only digital assets that will be required in the future, with others being redundant).
While decentralisation is the absence of dependency on centralised bodies such as regulating intermediaries and authorities, decentralisation maximalism is the notion that decentralisation is the best method and lifestyle to the point where any sort of regulation is unnecessary.
