The cryptocurrency community was shaken by an unconventional idea that challenged one of Bitcoin's fundamental principles. StarkWare co-founder and Zcash co-creator Eli Ben-Sasson stated that the hard supply cap of 21 million coins is meaningless in the long term. His argument is based on relentless erosion: wallet keys are lost, and on an infinite time horizon, all coins will be irretrievably lost, making the fixed supply practically unenforceable.
The Essence of the Proposal: Control Over the Emission Rate
Instead of an absolute cap, Ben-Sasson proposes a fundamentally different approach—fixing not the total quantity, but the maximum annual emission rate. He suggested a reasonable figure of 4% per year, arguing that this metric correlates with the growth rate of the human population. In his view, such a mechanism ensures that there are "enough coins for everyone," while preserving scarcity, albeit in a different form. The key message is to limit not the volume, but the inflation rate.
Separately, Ben-Sasson addressed the "security budget" issue. As the block reward approaches zero, the network will have to rely solely on fees, creating potential security risks. He also mentioned alternative mechanisms, such as Shielded Labs' Network Sustainability Mechanism, calling it "extremely interesting," and the demurrage mechanism (a fee on inactive coins), which he considered a more radical change.
Community Reaction: "Sacred Cows" and Historical Parallels
The idea sparked a heated and predominantly negative reaction. Critics called the 4% emission a transformation of Bitcoin into "fiat with extra steps." Others drew a historical parallel with the Roman Empire, where the debasement of coinage led to devaluation, seeing the proposal as a dangerous precedent.
The most emotional opponents urged not to touch "the only sacred, scarce, and decentralized digital money" and suggested experimenting with other cryptocurrencies. In response, Ben-Sasson posed a key question: can scarcity be preserved with an extremely low but constant increase in supply? He countered that stagnation and an inability to adapt could also lead to collapse, and asked why changing this particular narrative is categorically unacceptable.
Cryptalist Analysis: Ben-Sasson's very framing of the question is a ticking time bomb under one of Bitcoin's main narratives. Although at this stage, community consensus will likely reject the idea, it reveals a fundamental dilemma: how to maintain scarcity and network security in a world where keys are lost and fees are unstable. This is not a question of "to change or not to change," but a question of "when and how" adaptation will be necessary if Bitcoin truly aspires to be a global currency for centuries to come.
