Bitcoin Core developers received mixed reactions from the Bitcoin Community when they released their latest v30 release, which brought forward node-related improvements to security, performance and architecture.
Bitcoin Core 30.0 introduces encrypted connections as an option between nodes to improve privacy. It also increases the OP_RETURN (data) limit. Bitcoin Core Software can be increased from 80 bytes to 100 thousand, which allows for a much larger amount of data that is not financial to be included in Bitcoin transactions.
“With the release of this new major version, versions 27.x and older are at ‘End of Life’ and will no longer receive updates,” This Sunday’s announcement includes the following:
The biggest problem with the latest update is not the bug fixes or performance enhancements, but the fact that the fee rate has changed. stir debate in the community This is an increase in the limit of OP_Return.
The data cap has been increased by a large amount, allowing for more data-hungry and sophisticated decentralized applications to be developed on the Bitcoin network. But purists argue that Bitcoin should only ever be used as a network of financial transactions.

The New Block Size Wars
The current debate, while not a change in protocol, brings back memories. block size wars 2017 which led to the Bitcoin Cash hard fork.
Alex Bergeron from Ark Labs Ecosystems Lead sees this update as good news. said X informed me on Friday of his intentions “to use all of the additional OP_Return space and WILL use it to make Bitcoin more like Ethereum, except better.”

Satoshi Labs’ co-founder Pavol Russell also said yesterday that he would be opting for Bitcoin Core v30 because of having “great development team, peer-reviewed code,” The following are some examples of how to get started: “sane engineering decisions.”

Some were less optimistic. They argued that this goes against Bitcoin’s basic principles as a peer to peer electronic cash system, and it could result in blockchain overgrowth, higher node operating costs, and legal issues.
Alternative node software, also known as “knots,” It allows them to enforce strict limits on data sizes, like 80 bytes for transactions.
“As a (hopefully) temporary measure, run Knots. I strongly recommend not upgrading to Core v30,” noted Nick Szabo is a pioneer cryptographer.

Szabo, who raised his concerns in this past month regarding the legal implications of increasing the data limit, expressed concern that node operators could be held liable for hosting “illegal data.”
“Without adding safeguards to allow archival node operators to non-disruptively delete illegal content for which they will often be held criminally liable,” He noted X for Oct. 2
Luke Dashjr the founder of knots hasn’t made any comments on this update since its launch. However, he is critical of Bitcoin Core’s latest update.

Knots is used by a large number of operators. BitRef data indicates that currently there are 5114 Knots servers, or 21.48%, of all Bitcoin nodes.
