Bitcoin’s
Scheduled for release on October 30, Bitcoin Core 30 will lift the old 80-byte limit on the OP_RETURN function, and replace it with a cap of 4 megabytes per output.
This will enable users to include more content, such as full documents, text, and images, directly in Bitcoin transactions. Developer Gloria Zhao confirmed the change in a GitHub post on June 9.

Zhao explained that the role of developers is not to decide what kinds of transactions are acceptable. Instead, she said it is up to users to decide how they want to use the blockchain.
Additionally, the lead author of the proposal, Peter Todd, views this as a means to unlock new applications for Bitcoin beyond payments.
Developers had already hinted back in May that this update was coming. OP_RETURN gained recognition when it was utilized to embed items such as non-fungible token (NFT) style images.
However, the expanded data limit has caused disagreement within the community. Some longtime supporters argue that this kind of update contradicts what Bitcoin was intended to be: a simple, secure tool for sending money.
Dennis Porter, CEO of the Satoshi Action Fund, stated that he had helped raise over $200,000 to support the work of Bitcoin Core developers, but now feels let down and will not be donating again.
