Recently, I noticed an interesting data point: the number of active validator nodes on the Solana network has dropped significantly, from over 2,500 in March 2023 to around 800 now. This is quite a substantial decrease, and the change in the network’s level of decentralization is worth paying attention to. Some say it's a cost issue that has filtered out smaller nodes, while others believe it’s a natural consolidation as the network matures. Either way, the fact that the number of validators has been cut in half raises questions about Solana’s security and censorship resistance. The community is already buzzing with debate.
