Solana’s surging NFT market share could intensify its competition with Ethereum (ETH). In 2023, Solana’s NFT volumes nearly doubled, reaching $133 million in September, while ETH’s dominance dropped from 95% to 80% by 2022. This shift pressures ETH, whose slower 15 transactions per second (TPS) and high gas fees contrast with Solana’s 65,000 TPS and near-zero costs, driven by its Proof of History (PoH) and Proof of Stake (PoS) hybrid. ETH’s transition to PoS improved efficiency, but Solana’s scalability and speed give it an edge for NFT trading. However, ETH retains a mature ecosystem with vast DeFi and NFT infrastructure, while Solana faces centralization concerns due to fewer validators. If Solana sustains this momentum, it could challenge ETH’s NFT supremacy, though ETH’s established network may resist displacement. Technical superiority alone won’t dethrone ETH—adoption will decide.
