A max-plus perspective on package relay and block assembly

The discussion highlights a critical issue within the blockchain technology realm, specifically addressing inefficiencies in the GetBlockTemplate (GBT) interface used in Bitcoin mining. The primary concern is that the GBT interface does not accurately predict the size of the coinbase transaction, leading to a conservative estimation that often results in blocks not being filled to their maximum capacity. This flaw is not merely an oversight but has persisted over time due to what is described as abusive and anti-competitive behavior by certain individuals within the community, making it unappealing for developers to attempt any modifications or improvements.

Moreover, the assertion points towards a misconception regarding block space utilization. Contrary to what some might believe, the availability of space within blocks for transactions is generally not an issue, as evidenced by the flat slope of the fee rate in the feerate ordered mempool around the block limit. This indicates that there is usually sufficient room to include additional transactions in each block, which contradicts common narratives suggesting that blocks are running out of space. This situation underscores the need for technical solutions and community efforts to address and rectify these longstanding protocol inefficiencies.
