Bitcoin Core Removes OP_RETURN Limit in Software Update

The removal of the OP_RETURN limit may significantly affect Bitcoin’s role, extending beyond financial services. Experts express divided views on how this change impacts miner revenue and Bitcoin’s fundamental purpose.

The recent decision marks a major shift in Bitcoin Core’s software, aiming to enhance transparency and data management on the network. Greg Sanders, a key advocate, believes removing the limit cleans the UTXO set. Conversely, critics worry about potential spam risks.

Key Debate: Sanders vs. Dashjr

Greg Sanders and Luke Dashjr are central figures in this debate. Sanders supports the removal, citing benefits for data handling, while Dashjr warns of spamming risks, shifting Bitcoin’s financial functionality. The plan is set to launch in the forthcoming update.

Implications for Miners

Removing the OP_RETURN limit has significant market implications, especially for miners already profiting from Ordinals-related activities. BitMEX notes a surge in miner fees due to Ordinal inscriptions, totaling over 7,000 bitcoins.

The potential financial outcomes may include changes in miner incentives and network usage patterns. The decision could also push regulatory discussions around Bitcoin’s expanded data capabilities. Historical parallels, like the Ordinals introduction, highlight the contentious nature of network modifications.

“Large-data inscriptions are happening regardless and can be done in more or less abusive ways. The cap merely channels them into more opaque forms that cause damage to the network.” — Greg Sanders, Core Contributor, Blockstream
