Episode notes
Cultural Rift Drives More Damage Than Code
- The OP_RETURN debate is mostly cultural, not purely technical, and damaged community trust.
- Social dynamics and perceived dismissiveness caused long-term loss of engagement more than the technical change itself.
Block-Space Markets Now Enforce Usage
- Today blocks are ~91% full and miners/pools are more sophisticated, so old informal mempool pushes are less effective.
- Block-space market dynamics now regulate which uses get included via economic density.
Manage UTXOs To Reduce Fee Waste
- Consolidate or manage UTXOs to improve fee efficiency and compete for scarce block space.
- Use batching and UTXO management to avoid being crowded out by higher economic-density transactions.
