Bitcoin Core v30 Released: OP_RETURN Limit Boost Draws Mixed Reactions

TLDR

• Bitcoin Core v30 introduces a significant increase in the OP_RETURN data limit, allowing up to 100,000 bytes.
• The update includes optional encrypted connections between nodes to enhance privacy and security.
• The OP_RETURN change has sparked debate within the Bitcoin community over potential blockchain bloat and legal risks.
• Some Bitcoin enthusiasts embrace the update as a step toward more sophisticated decentralized applications.
• A growing number of node operators are using Knots software to enforce stricter data limits on Bitcoin transactions.

Bitcoin Core developers have released version 30.0, introducing significant changes in node architecture, performance, and security. The update includes optional encrypted connections between nodes and increases the OP_RETURN data limit from 80 bytes to 100,000 bytes. This change allows more non-financial data to be embedded within Bitcoin transactions, sparking controversy among community members.

Bitcoin Core OP_RETURN Change Sparks Debate

The decision to raise the OP_RETURN limit has become the focal point of heated discussions. Bitcoin purists argue that the network should only be used for financial transactions, not for storing large amounts of data. Critics fear that this change could lead to blockchain bloat and higher node operation costs.

Some see the change as a positive development, especially for decentralized applications (dApps). Ark Labs Ecosystem Lead Alex Bergeron voiced his support, stating his intention to use the increased OP_RETURN space. He tweeted, “I WILL use it to make Bitcoin more like Ethereum, except better.”

However, many are concerned about the legal implications of storing large amounts of non-financial data. As Nick Szabo, a prominent cryptographer, warned, “Node operators risk hosting illegal data.” Szabo believes that without safeguards, operators could face criminal liability for hosting such content.

Knots Software Gaining Popularity Among Operators

To address concerns, many node operators are turning to alternative software, such as Knots. This software allows operators to enforce strict limits on transaction data, such as the 80-byte limit. According to BitRef data, 21.48% of all Bitcoin nodes now run Knots software.

Knots offers an effective workaround for those who wish to avoid the larger OP_RETURN data limit. Its founder, Luke Dashjr, has been critical of Bitcoin Core v30 but has not commented on the release since its launch. Despite the controversy, the number of Knots nodes continues to grow, reflecting the division within the community.

In conclusion, Bitcoin Core v30 has introduced significant changes, including the controversial OP_RETURN update. While some embrace the change, others remain wary of its potential consequences. The debate surrounding Bitcoin Core v30 highlights the ongoing tensions within the Bitcoin community over its future direction.
