Fee Selection for CTV-Based Mining Pool Fanouts

The concept explored involves enhancing the efficiency of blockchain transactions by utilizing a specifically designed API that allows miners to access non-standard fanout transactions. By hosting these transactions in an accessible manner, miners can append their fees to transactions initially set with zero satoshis (0-sat anchor). After attaching the necessary fee, the modified transaction becomes a standard one-input-one-coin (1p1c) package. This alteration not only facilitates the transaction's acceptance across the network but also streamlines its broadcast through the mempool, ensuring a smoother relay across the node network. This approach could potentially optimize transaction processing times and costs, leveraging the existing infrastructure while introducing minimal disruption.
