Solana's surging NFT market share intensifies its competition with Ethereum (ETH). In December 2023, Solana's NFT sales hit $366.5 million, surpassing ETH's $353.2 million, driven by lower fees and faster transactions. Solana’s technical edge lies in its Proof of History (PoH) and Proof of Stake (PoS) hybrid, enabling over 65,000 transactions per second (TPS), compared to ETH’s 15-30 TPS, even post its PoS upgrade. ETH’s higher gas fees and slower speeds often deter NFT creators, while Solana’s near-zero fees and scalability attract them. However, ETH retains a larger ecosystem and network effects, hosting 95% of NFT volume historically. Solana’s growth challenges ETH’s dominance, but its smaller validator pool raises centralization concerns, unlike ETH’s more decentralized network. This technical disparity fuels a dynamic rivalry.
