Intent-driven transaction protocols face competitive barriers shaped by solver node density and economies of scale from signature data assetization. High solver node density, as seen in protocols like 1inch Fusion, enhances efficiency through competitive intent fulfillment but requires significant staking and infrastructure costs, creating entry barriers. Signature data assetization leverages aggregated transaction data to optimize pricing and execution, yielding economies of scale. Platforms with dense solver networks and robust data systems benefit from lower per-transaction costs and improved user experience, deterring new entrants. However, high fixed costs for solver operations, including specialized hardware and cross-chain inventory management, limit scalability for smaller players. Established protocols with large solver pools and data-driven optimization dominate, as network effects and cost efficiencies reinforce their market position, making it challenging for newcomers to compete effectively.
