As blockchain networks grow and their data expands, the demand for storage increases. This leads to concerns about the centralization of full nodes, as larger corporations with significant resources might dominate node operation, potentially undermining decentralization. Individuals often lack the resources to run full nodes, impacting their influence on network consensus. This raises questions about the long-term decentralization of blockchain networks. How can we address these challenges and ensure that blockchain remains truly decentralized?
Aside blockchains using POW, I don't really know any other blockchains mechanism that is entirely decentralized but Bitcoin security make it stands above every other blockchains using POW, which have been affected by the 51% hack.
You should note that all bitcoin miners are full noders, resources needed to run a node will be added to their expenses in mining and so if centralization hasn't happened now, I don't think it will happen in the long. In addition to this we have individuals who will continue to run full nodes and so there is no much worries about centralization in regard to Bitcoin.
pooya87, as spoken about the essence of limiting block size which makes Bitcoin network stands strong in security and decentralization than any other blockchains
