ReardenCode, independent Bitcoin developer and freedom advocate, joins us to talk about reframing how we think about Bitcoin soft forks. Reardon breaks down opcodes, explains why we should focus on capabilities rather than protocols, and explores the historical context of Bitcoin's upgrades from SegWit to Taproot. The conversation goes deep on OP_CAT, CTV, and CHECKSIGFROMSTACK while but tries to make the topics approachable approachable.
Follow our guests: @ReardenCode
Notes:
- Bitcoin is the first digitally scarce asset
- OP_CAT enables five different capabilities
- SegWit enabled non-third party malleable txs
- Taproot enabled hidden script paths
- CTV+CSS combo enables rebindable signatures
- MEV concerns can probably be scoped and managed
