Who owns bancor network?

Could you please elaborate on the ownership structure of the Bancor Network? I'm curious to understand who holds the keys to this decentralized platform and what role they play in its governance and decision-making processes. Is it a collective of developers, investors, or perhaps a decentralized autonomous organization (DAO) that oversees the network's operations? Furthermore, what measures are in place to ensure transparency and accountability among those who have a stake in the Bancor Network?
