Transaction rebroadcasting aids in the following ways:
Rapid propagation of new transactions. If the transaction carries a lower fee compared to the prevailing market rate, Bitcoin nodes prioritize distributing other transactions with higher fees. Consequently, it is common for major mining nodes to remain unaware of your transaction if it hasn't reached them.
Mining nodes become aware of your transaction. This is important, especially when the network is congested. Your fee might be enough, but the miners don't know about your transaction. When you launch a new transaction, the rebroadcasting service helps to start mining blocks with it faster.
Some miners do not have access to the entire mempool. Often, we observe blocks being mined with transactions that may not be the most optimal at that moment. Consequently, there's a possibility for your transaction to be confirmed, even if there are others with higher fees. This happens because miners are aware of your transaction but might not be aware of others.
Re-committing the transaction to the mempool after purging. When the mempool becomes congested with numerous transactions, most nodes begin purging those with lower fees. Utilizing the rebroadcasting service, you reinsert your transaction. This becomes particularly crucial when network load diminishes, as it is the sole method to reintroduce your transaction into the mempool.
It should also be noted that Bitcoin nodes are configured by default to drop transactions from the mempool if they are older than 14 days. This means that transactions not confirmed within this period are forgotten. In such cases, our free service can help restore them.
You can distribute transactions with a lower fee than what most nodes can currently accept. The reason is that we are working with nodes set to support a larger or even unlimited mempool. Thus, these nodes will take care of the propagation of your transaction to ensure it does not fall out of the mempool of other nodes.
Transaction rebroadcasting can be beneficial in certain situations, particularly when the network is not excessively congested. However, it should be noted that this service is provided free of charge and cannot be compared to the prioritization of transactions by mining pools. In heavily congested networks, its impact may be minimal. In such cases, it is advisable to consider alternative forms of transaction acceleration.
