Bitcoin News: Who Will Triumph in the “OP_RETURN” Battle?

BTC developers are in disagreement over a proposal aimed at removing the existing 83-byte restriction for the OP_RETURN function. Who will prevail? Will the protocol experience a protocol split? The last instance of a BTC hard fork occurred in September 2017.

Tensions are rising in the Bitcoin community, potentially leading to another significant hard fork after nearly eight years. A technical discussion surrounding a specific protocol feature has escalated into a full-scale ideological battle. Central to this dispute is pull request 32359, which aims to eliminate the 83-byte data restriction on the BTC OP_RETURN function.

The “OP_RETURN” Conflict: Who will prevail?

Since this data limit was established, Bitcoin transactions have been capable of containing minor amounts of non-financial information.

Currently, a proposal seeks to eliminate this constraint, enabling files larger than 83 bytes to be directly embedded within BTC transactions. This modification would affect both the distributed database size and validator operations.

The discourse has transformed into a public event, with advocates and adversaries clashing, each convinced their stance is the most beneficial for the platform.

Any modification will either align Bitcoin with Satoshi Nakamoto’s original vision as a financial infrastructure or convert it into a general-purpose distributed ledger, cluttered with potentially unnecessary files.

In this OP_RETURN conflict, divisions are forming, echoing the BTC controversy of September 2017, which resulted in the creation of BTC Cash following a protocol fork. Although Bitcoin Cash has waned in significance, it remains one of the top cryptos to buy in 2025.

To grasp the importance of this debate, one must understand the reasoning behind the OP_RETURN function’s introduction.

First introduced in 2014, this feature was created to provide a lightweight method for attaching transaction data, like timestamps, to BTC transactions.

Although part of the transaction, its purpose was to keep the network “light” and prevent congestion. It was capped at 83 bytes to prioritize crucial financial information. However, ongoing debates question whether this limit enhances utility, efficiency, or both.

Pull Request 32359, put forth by Peter Todd and Antoine Poinsot from Chaincode Labs, aims to remove this restriction. Rather than being limited to 83 bytes, anyone could embed files of any size, essentially allowing on-chain storage.

Which Path for Bitcoin?

Proponents contend that the limit is antiquated, especially following the introduction of Taproot that facilitated inscriptions and innovations like tokenization.

Moreover, private mempool broadcasting services, like MARA Slipstream, already permit larger files to be stored on the distributed record.

In a post on X, Todd indicated that the limit renders BTC “less efficient” and that removing it would rearrange OP_RETURN’s complete fee structure.

“Your use of the software is giving the attackers the power to carry out their attack. Remove that power.”

Conversely, Bitcoin purists, including core developer Luke Dashjr, regard the proposal as “complete insanity,” cautioning it may lead Bitcoin to become a data landfill.

They cite the recent surge in inscriptions, which increased transaction fees and put pressure on nodes.

It didn’t used to be this way – the devs just instinctively knew to avoid using BTC for arbitrary file storage, making all efforts to deter that practice.

Removing the limit and introducing non-essential data could jeopardize Bitcoin’s goal as “internet money,” thus diminishing the network’s value.

BTC Core developers are about to implement a change that will render BTC a worthless alternative coin, and no one seems to care enough to intervene.

I’ve raised concerns, lost sleep over this matter, and despite clear community backlash against the PR, it continues to progress.https://t.co/dMcQ4g8RjV

This faction urges the community to impose strict guidelines to maintain Bitcoin’s core mission.

For now, the community’s reception of this proposal is under scrutiny. As Bitcoin transcends mere code: It embodies a movement valued at over $1.88 trillion.

Consequently, the discussion is expected to escalate over time, accompanied by intriguing insights. Nevertheless, whether a hard fork is impending remains uncertain.
