Stellar Development Foundation CEO Denelle Dixon has issued a warning about the potential for monopolistic practices in the blockchain industry. In a recent essay, Dixon highlighted the risk of private companies creating closed, vertically integrated networks, drawing parallels to 19th-century railroad monopolies. She cautioned that such corporate-controlled blockchains could lead to centralized chokepoints in the global financial system. Dixon emphasized the need for open standards, transparency, and user choice to prevent these outcomes. She urged developers and policymakers to focus on collaboration rather than control, ensuring that blockchain technology remains inclusive and interoperable. Her call to action aims to preserve the decentralized ethos of blockchain and prevent the concentration of power in the hands of a few entities.
