An ideological rift is brewing in the world of cryptocurrencies. StarkWare co-founder and CEO Eli Ben-Sasson has made a radical proposal that challenges one of Bitcoin's main pillars — the fixed limit of 21 million coins. In his view, this model has no practical meaning, and he calls for replacing it with an annual issuance of 4%.
Ben-Sasson's argument is based on the problem of irretrievably lost keys. Over time, as he rightly notes, owners lose access to their wallets, and coins permanently disappear from circulation. According to Ledger estimates, the volume of such "burned" bitcoins has already reached 4 million. "If you look at an infinitely long period, eventually all keys will be lost," he wrote, emphasizing that in the long run, the reduction in circulating supply will only accelerate.
As an alternative, the StarkWare head proposes abandoning the hard upper limit and switching to a predetermined annual issuance rate. Inflation of 4%, in his opinion, is "natural" and corresponds to the long-term growth rate of the Earth's population. From an economic perspective, this is an attempt to create a model where supply is not static but dynamically adapts to losses, while maintaining the asset's predictability and scarcity.
Community Reaction: A War of Narratives
The proposal sparked a heated but predictably negative reaction among Bitcoin maximalists. For them, the 21 million BTC limit is not just a technical detail but the very essence of the "digital gold" concept. As one user aptly noted: "This is probably the last narrative keeping Bitcoin afloat. Soon it will just become another dollar." Critics point out that any protocol change that dilutes scarcity destroys the trust on which the entire value of the asset is built.
The main counterargument from supporters of the current model is that Bitcoin is divisible into 2.1 quadrillion satoshis. They dismiss the argument that "there won't be enough coins for everyone" as untenable. However, Ben-Sasson counters that even this number of units will practically shrink due to key loss, making division into satoshis only a temporary solution.
In Search of Compromise: Alternatives from Zcash
Zcash founder Bryce "Zooko" Wilcox intervened in the discussion, proposing a more elegant compromise — the Network Sustainability Mechanism (NSM). This model retains the hard limit of 21 million but allows users to voluntarily burn coins. An equivalent amount is then gradually returned to circulation through miner rewards over four years. This approach solves the network security problem without increasing the maximum supply, making it a much more acceptable option for purists.
Expert Opinion: Ben-Sasson's idea is undoubtedly an intellectual challenge, but from a practical standpoint, it is utopian. Changing Bitcoin's issuance model is not just a hard fork; it is a change in its identity. Even if mathematically 4% inflation seems reasonable, the psychological barrier for the community is insurmountable. Bitcoin has become a symbol of absolute scarcity, and any attempt to "tweak" it will be seen as betrayal. In my view, the future lies in more flexible solutions like NSM, which allow security issues to be addressed without encroaching on the sacred 21 million limit.
