Tossing Limits: Bitcoin Core Team Plans to Scrap 80-Byte OP_RETURN Restriction in Upcoming Update
Bitcoin Regulation Developments Spark Division Among Stakeholders
Bitcoin's developers have stirred the crypto world with their plans to ditch the 80-byte restriction on OP_RETURN outputs in the imminent software upgrade. This bold move has ignited a storm of debate.
On May 5th, Bitcoin coder Gregory Sanders dropped a bombshell on GitHub. He shared that the upcoming version will allow OP_RETURN outputs to exceed 80 bytes and accommodate multiple OP_RETURN operations. Sanders highlighted that the initial 80-byte cap aimed to economize block space, but it's now redundant as many miners and users flout it.
Intricate strategies like crafting fake open keys or concealing data in spendable commands disrupt network efficiency and make management harder. Attempts to blacklist have been dismissed by devs, with concerns about the system's longevity and risks to users' funds looming large.

Sanders clarified that fundamental rules, such as the 4 million unit block size, will stay intact. This decision will contribute to tidying up the UTXO set and fostering a cohesive network behavior.
The team considered three options: maintaining the status quo, incrementing the limit, or entirely removing it. The third option, although not universally supported, has garnered considerable backing.
Community Rumble on the Announcement
This decision has set the crypto community abuzz with disagreements. Bitcoin Knots coder Luke Dashjr labeled it as "heroic folly." Notable figure Samson Mow suggested that users could stay on v0.29.0 or use alternative software.
Marty Bent, Ten31 Fund manager, criticized the decision's implementation without substantial dialogue, stating, "It's just not happening."
Sanders insists that recent Bitcoin modifications correspond with its original, simplistic rulebook, but a large segment of the community strongly disagrees. A GitHub comment declared, "This decision marks a pivotal moment in Bitcoin's voyage," while another proclaimed, "This is a monumental error the Core team can ill-afford."

The current discourse revolves around three main aspects:
- Purpose and consequences of OP_RETURN:
- Supporters: OP_RETURN was designed to permit users to insert tiny amounts of data in transactions, avoiding bloating the unspent transaction output (UTXO) set. Removing the limit aligns Bitcoin Core's policy with existing behaviors by miners and other node implementations, eliminating inefficiencies and reducing UTXO clutter[4][5].
- Detractors: Lifting the limit could foster network spam, with larger data amounts stored, potentially tarnishing Bitcoin's reputation as a secure monetary platform[2][5].
- Pragmatic Considerations:
- Inefficiencies and Bypassing: The cap has been bypassed via creative workarounds like "ghost" public keys. Eliminating such inefficiencies by formalizing larger OP_RETURN sizes is seen as beneficial[5].
- Fee Management: Proponents argue that market factors like transaction fees will control data usage, making the limit elimination a more market-driven approach[5].
- Philosophical Divides:
- Bitcoin’s Role: The debate underscores profound philosophical differences about Bitcoin's purpose. Some view removing the limit as faithful to Bitcoin's minimalistic ethos, while others see it as a departure from Bitcoin's primary role as a monetary system[4][5].
- Community and Development Response:
- Division and Uncertainty: The proposal has polarized the community, with no consensus yet on its underlying implications or future impact. The impending modification is set to be part of the next Bitcoin Core release, although an official release date remains undisclosed[4].
The debate encapsulates a broader discussion about Bitcoin's future trajectory, balancing innovation with preserving its fundamental monetary functions.
- The discussion unfolding in the crypto community, following the Bitcoin Core team's plan to remove the 80-byte limit on OP_RETURN outputs, revolves around the impact on crypt technology.
- Some argue that the removal aligns with existing behaviors of miners, eliminating inefficiencies and reducing UTXO clutter, thereby enhancing the functionality of crypt technology, while others fear it could lead to network spam, potentially tarnishing Bitcoin's reputation as a secure monetary platform.
