BIP-141 (SegWit) created a 4× weight discount for witness data — designed for malleability, not state economics. The result: an unpriced externality of ~$0.008 per inscription that every full node operator bears. This article presents the full UTXO cost model, verification appendix, and sensitivity analysis across 6 node scenarios.
Inscriptions are 0.91% of block space. Pruned nodes avoid ~70% of storage overhead but still pay 100% of bandwidth and CPU to download and verify every inscription before discarding it. The unavoidable cost: ~$2.53/yr per node. At 50K reachable nodes, that's ~$126K/yr aggregate. At 50× volume growth, it becomes significant.
Analysis of the 126-comment Reddit discussion on BIP-110. Key themes: Peter Todd's proof that the BIP is structurally ineffective (he embedded the full BIP text in a compliant transaction), Greg Maxwell's confiscation concern, the 55% threshold controversy, and Michael Saylor calling it "iatrogenic."
A community member argues that if node operation becomes a hobbyist activity, the externality argument collapses. Counterpoint: Bitcoin's value depends on anyone being able to verify their own transactions. If node operation drifts from "cheap enough for anyone" to "hobbyist only," that's a security concern beyond inscription pricing.
A more precise framing of the research question. The externality argument only holds if node operators bear costs without compensating benefit. If every node operator either values the data or is compensated for storing it, there's no externality — the market works. Our response: the unavoidable bandwidth+CPU cost of downloading and verifying inscriptions before pruning is the portion that isn't priced.
A detailed 10-point critique of BIP-110 covering: protocol neutrality violations, Peter Todd's bypass demo, incentivized centralized block space markets, confiscation risk, broken eltoo/ln-symmetry, UTXO bloat, broken Miniscript, lobotomized BitVM, lost miner fees, and the rushed governance precedent at 55% threshold.
