The use of the Coin Age Priority algorithm by some miners at OCEAN during block template construction using DATUM has sparked discussions within the cryptocurrency community. This algorithm prioritizes older coins, i.e. those that have been sitting unspent for longer periods, over newer coins when selecting transactions to include in blocks. While this approach was originally used in Bitcoin Core before being phased out around the time of Segwit, it is still maintained in Bitcoin Knots.
The motives behind the use of this algorithm by OCEAN miners can only be speculated upon. Some believe it may be driven by a desire to prioritize “financial” transactions over others, while others suggest it could be a way to assist small value UTXO owners. However, regardless of the reasons, this approach is seen as irrational by many in the community.
Miners have the freedom to partition blockspace and prioritize transactions as they see fit. However, it is important to recognize that blockspace is a fungible commodity valued on an open market. Any criteria used to select transactions other than the feerate can result in missed revenue opportunities for miners. Additionally, creating a subsection of blockspace based on alternative criteria can lead to competitive pressures that do not directly benefit miners financially.
Ultimately, the use of non-feerate criteria in selecting transactions does not alleviate fee pressures; it simply results in miners earning less revenue and users facing different competitive dynamics. It is crucial to acknowledge that blockspace is a commodity subject to market forces, and attempting to censor certain types of transactions can undermine the core principles of Bitcoin.
Maintaining a decentralized and widely distributed mining network is essential for ensuring Bitcoin’s censorship resistance. It is concerning to see smaller miners engaging in economically irrational behavior, as this can have long-term implications for their success in the industry.
In conclusion, the use of the Coin Age Priority algorithm by OCEAN miners highlights the complexities of transaction selection in blockchain technology. It is important for miners to consider the broader implications of their actions and prioritize strategies that align with the fundamental principles of Bitcoin.
