Is ArcBlock decentralized?

Could you elaborate on the decentralization aspect of ArcBlock? I've heard it mentioned in several discussions but I'm still unclear on how it truly achieves decentralization. Is it a fully decentralized blockchain platform, or does it have some centralized components? What measures have been taken to ensure that ArcBlock remains decentralized as it grows and evolves? Understanding this aspect is crucial for me to assess its potential and suitability for my financial and cryptographic needs.
