To counteract this, Bitcoin Core has implemented several strategies. One is to require replacement transactions not only to cover the fees of the transactions they replace but also to include an additional fee for the new data circulated across the network. Furthermore, when the memory pool nears its capacity limit of 300MB, it enforces a minimum fee requirement for new transactions that must exceed the highest fee of the recently removed transactions plus a standard incremental rate. This effectively elevates the cost barrier for incoming transactions during peak times. Additionally, any transaction lingering in the mempool for over two weeks is purged to prevent prolonged free relay.

A proposed solution, known as "V3," aims to circumvent certain technical problems by enforcing more stringent rules on transactions that opt into this policy. It restricts network topology to minimize unpaid transaction relays and limits the size of certain transaction components, thereby addressing pinning concerns while also preventing new opportunities for free relay. Future enhancements to the memory pool system, as detailed in Future mempool updates, may refine these policies to better align with economic incentives and resistance to transaction pinning.

In contrast, there is a viewpoint that suggests the free relay issue should be less of a concern. Peter, a voice in the community, argues that since miners can already generate some degree of free relay through selective transaction processing, the network might as well embrace a more liberal approach to transaction relay. He contends that a broader allowance for such transactions could be implemented, arguing that miners foregoing certain fees is not equivalent to enabling all network users to do so. However, his initial proposal encountered flaws that permitted unlimited free relay, although he asserts these have been rectified by introducing further restrictions. Despite this, many believe that efforts should concentrate on refining the Replace-by-Fee (RBF) protocols to ensure proper incentivization before abandoning the safeguards against free relay altogether, especially considering the complexities involved in analyzing the current RBF rules.
