🚨 Bitcoin Core 30.0 has arrived: OP_RETURN now supports up to 4MB. Revolution or threat? 💣

The new version of Bitcoin Core has been released and brought the largest expansion of OP_RETURN in history.

📌 From 80 bytes → up to 4 MB per transaction 😱

📌 Multiple OP_RETURN fields are now allowed

📌 577 improvements in the code (faster IBD, CMake, Stratum v2 and more)

🔍 But why does this matter?

OP_RETURN allows the insertion of arbitrary data into the Bitcoin blockchain. Now, with much more space available, the network can be used for things beyond financial transactions — such as NFTs, messages, files, and even ordinals.

🎯 For some, it is the future of programmability in Bitcoin.

⚠️ For others, it is congestion disguised as “innovation.”

🔧 Other important changes:

🛠️ Limit of 2,500 signature operations per tx (protection against DoS)

💸 Minimum fees adjusted (block minting fee now at 0.001 sat/vB)

⚙️ IBD 20% faster + wallet migrated 100% to descriptor wallets

🧠 Question for the community:

Is this change a step towards a more versatile Bitcoin?

Or are we playing with fire and compromising the original mission of $BTC ?
