Started doing more research on how Bitcoin Core's developers have been attacking its sovereign/Medium-of-Exchange use a while back and it's wild.
The post became too long for email just from covering:
1. SegWit (BIP141): The “Witness Discount” and Block-Weight Accounting
2. Taproot (BIP340–342): Easier Complex Scripts and Data Embedding
3. Liberalized Data-Carrier Policies (OP_RETURN and “Standardness”)
4. Replace-By-Fee (RBF): From Opt-In to Broad Default
5. Relay and Mempool Settings that favor Large Players
6. Legal-Risk Externalities shifted to Node Operators
7. Increased Block Weight → Centralization Pressure
8. Convenience Defaults: Assumevalid, Pruning, and Checkpoints
9. Deprecation of Non-Standard Scripts
10. Fee-Market “Purism” — No Priority for Payments
11. Lightning Network Bias — L1 as Settlement Only
12. Governance Activations Show Who Sets the Rules
13. Quiet Merchant De-Feature: BIP70 Payment Protocol Deprecation
14. Removal of “Priority by Coin Age” & Free Relay (historical)
15. Dust Limits & MinRelayFee Floors as Gatekeepers
16. Core v30: OP_RETURN/data-carrier expansion (policy)
17. Core v30: RBF ergonomics tilt further to replaceability (wallet/API surface)
18. Core v30: Multiple OP_RETURNs per tx
Have written this in as simple as possible terms for non-developers. Will post later when done.
