Solana’s surging NFT market share intensifies its competition with Ethereum (ETH), driven by lower fees and faster transactions. Solana’s Proof-of-History (PoH) and Proof-of-Stake (PoS) combo enables over 60,000 TPS, dwarfing ETH’s 15-30 TPS, even post-PoS transition. This scalability attracts NFT creators and traders, reducing costs (Solana fees < $0.01 vs. ETH’s often > $50 during congestion). ETH retains a larger ecosystem and first-mover advantage, but Solana’s technical edge—high throughput, low latency—chips away at ETH’s dominance. Still, Solana’s centralization concerns (fewer validators) contrast with ETH’s robust decentralization, shaping their rivalry.
