How does cryptocurrency achieve autonomy?

As a financial practitioner with a keen interest in cryptocurrency, I'm curious to understand how this digital asset achieves autonomy. Could you elaborate on the underlying mechanisms that enable cryptocurrency to operate independently from traditional financial institutions? I'm particularly interested in the role of decentralized networks, blockchain technology, and consensus algorithms in ensuring autonomy. Additionally, how does the lack of central control or intermediaries contribute to the autonomy of cryptocurrency? I'd appreciate a concise yet comprehensive explanation of these core components and their interplay in enabling cryptocurrency to achieve autonomy.
