The number of active validators on the Solana network has dropped below 800, reflecting a significant decline in ecosystem participation. The number of validators has decreased by over 65% since the beginning of 2023, when there were 2,500, and voting transaction volume has also fallen sharply. The primary reason is adjustments to the economic incentive mechanism, but user trading activity remains stable, indicating that the network's basic operations are normal. Nevertheless, the reduced validator diversity may impact the network's decentralization and censorship resistance.
