Stats on compact block reconstructions

Aug 2 - Nov 23, 2025

  • The identification of 1376 instances where transactions were rejected due to 'bad-txns-inputs-missingorspent' indicates a significant number of transactions encountering issues with their inputs, either because they were not present in the mempool or had already been spent.

This scenario suggests these transactions could be orphans, which are transactions that reference inputs not yet recognized by the node's blockchain or mempool, essentially making them incomplete for processing and validation at the time of receipt.

The question regarding the subsequent handling of these transactions within the orphanage is crucial for understanding the broader implications of such rejections. The orphanage is a temporary holding area for orphan transactions until their missing parents (inputs) are received, allowing them to be fully validated and potentially included in future blocks. Investigating what happens later in the orphanage involves tracking these transactions to see if and when their missing inputs arrive, enabling their eventual acceptance into the mempool and inclusion in a block, or if they remain unfulfilled and are eventually dropped due to timeout or replacement.

This process underscores the dynamic nature of transaction validation and the challenges nodes face in managing dependencies among unconfirmed transactions. It also highlights the importance of efficient orphan management policies in maintaining the health and throughput of the network, ensuring that temporary setbacks in validation do not permanently hinder transaction finality. Further examination of the outcomes for transactions in the orphanage would provide valuable insights into the effectiveness of the node's strategies for dealing with orphaned transactions and improving overall network performance.
