Peter Todd’s advocacy for permanent Bitcoin block rewards has once again stirred intense discussion about the cryptocurrency’s fixed supply and future security model. The latest controversy began after the Bitcoin++ conference shared a recording of a presentation Todd delivered on July 23, 2026, in Toronto.
Titled “Tail Emissions and Demurrage,” the talk revisited concepts he has examined for several years.
Todd warned that once Bitcoin’s block subsidy ends around the year 2140, miners would depend entirely on transaction fees.
He argued that fee income can be highly uneven, creating situations in which large miners might find it profitable to reorganize recent blocks containing high fees rather than simply extend the chain.
To address this potential instability, Todd suggested a modest fixed reward paid in every block indefinitely—a mechanism known as tail emissions.
He maintained that such ongoing issuance would give miners a reliable baseline of revenue.
Drawing on the reality that bitcoin is continually lost through forgotten keys, damaged hardware, and incomplete estate planning, he proposed that a carefully chosen emission rate could eventually match the rate of loss.
In his framing, the circulating supply would stabilize rather than expand without limit.
As a related option, he discussed demurrage: a charge applied to coins that remain idle for long periods, with the proceeds directed toward network security.
The release of the video prompted strong reactions across social media. Many participants insisted that Bitcoin’s 21-million-coin limit is non-negotiable and forms the core of its value as scarce digital money.
They described tail emissions and demurrage as forms of perpetual inflation or a tax on holders, arguing that any change to the issuance schedule would undermine the protocol’s monetary credibility.
Critics contended that fee markets and second-layer settlement should be allowed to evolve organically to support security.
A smaller number of voices suggested that a very low ongoing issuance rate would be economically insignificant and might one day be considered, though they acknowledged the near-certainty of community resistance and the need for a hard fork.
Figures such as Adam Back highlighted the practical difficulty of achieving consensus for any alteration to Bitcoin’s supply rules.
Supporters of other protocol proposals also referenced the talk while advancing their own critiques of current development priorities.
Todd has noted that widespread adoption of a hard-fork change remains unlikely in the immediate future.
The exchange illustrates a longer-term tension within Bitcoin: balancing the need for robust miner incentives against the commitment to a predetermined, capped supply.
Subsequent halvings, the performance of the fee market, and improvements in coin custody will determine whether these ideas remain theoretical or gain practical urgency. For now, the dominant response underscores the community’s attachment to the existing monetary policy.
