Bitcoin developer Peter Todd's pitch for a permanent block reward has reignited backlash from users defending the network's 21 million coin cap. The dispute resurfaced after a July 23 conference talk was reposted this week, and separately, investment advisor Ross Gerber renewed criticism of Bitcoin's practical utility versus gold.
Bitcoin developer Peter Todd's proposal to give miners a permanent stream of new bitcoin has triggered fresh backlash from users who treat the 21 million supply limit as the asset's core promise. The fuse was lit when Bitcoin++ posted Todd's July 23 Toronto talk, "Tail Emissions and Demurrage," on Aug. 14. Todd has pushed tail emissions, a fixed number of new coins per block, since at least 2022, but the latest replay produced the same verdict from critics: inflation dressed up as engineering.
Miners face a shrinking subsidy
Miners earn from two sources: the block subsidy and transaction fees. One of those is shrinking on a fixed schedule. Every halving cuts the subsidy roughly in half, and by about 2140 it reaches zero, leaving fees to pay for security alone. Todd argues a fee-only system could produce lumpy jackpots that make it worthwhile for a large miner to attempt a chain reorganization instead of extending the existing chain.
Todd's trade-off: emissions or demurrage
Todd wants a small reward in every block after the subsidy fades, defending it with a leaky-bucket model in which lost keys and bad inheritance planning could offset the added issuance. He floated a loss rate of around 0.1% a year, which he frames as a model input rather than an observable fact. His backup proposal, demurrage, would charge coins when they are spent after sitting idle and route the proceeds to miners. One bitcoiner argued that 0.21 BTC per block equals 0.05% yearly inflation, calling the change minor next to broader economic productivity gains, even while acknowledging the community would likely never back it unanimously.
Skepticism beyond the supply debate
The supply-cap fight isn't the only challenge to Bitcoin's value proposition this week. Investment advisor Ross Gerber questioned Bitcoin's real-world utility, arguing gold remains easier to use in many places despite years of promises about crypto as a payment system. "Probably easier to use gold than bitcoin in most places still," Gerber wrote on X.
No imminent decision
Todd acknowledged a tail-emissions hard fork is unlikely within five years even if supporters settle on a design. Starkware CEO Eli Ben-Sasson has separately argued that capped supply does not make sense because keys will keep being lost over time. A mid-2026 Delving Bitcoin proposal separately outlined 0.25 bitcoin per block from about 2040 alongside fee burning, but each idea runs into the same resistance: a security fix that changes the money is a risk to its owners.
