Bitcoin OP_RETURN War Explained

May 11, 2025
40:10

What started as a technical proposal has exploded into community division, with accusations of "destroying Bitcoin" flying around. The hosts break down what OP_RETURN is, why some devs want to increase its size limit, and why others view it as enabling "spam" on the blockchain. At its core, this fight reveals deeper tensions about who controls Bitcoin's future and what the network should be used for.

Notes:

- OP_RETURN limit currently set at 83 bytes

- Proposal would increase limit to ~1 megabyte

- 30-45% of Bitcoin transactions are "non-financial"

- Bitcoin Knots node usage has grown to 7-8%

- Out-of-band transactions bypass node relay

- Core devs facing diminished community trust
