StarkWare CEO Proposes 4% Bitcoin Inflation Model

Eli Ben-Sasson, CEO of StarkWare, has once again reignited the discussion regarding the possibility of the fixed supply limit of Bitcoin to increase. In a recent post on X, he proposed replacing the current ceiling of 21 million Bitcoin with an annual issuance of 4%. This suggestion has led to fierce criticism from the Bitcoin community.

Ben-Sasson argued that the current limit is no longer logical, given the loss of private keys over time. According to his reasoning, if these keys continue to disappear, the effective amount of available Bitcoin will become nil in the future. Ledger, a manufacturer of crypto hardware wallets, estimated in November that up to 4 million Bitcoin had been permanently lost. Nevertheless, Ben-Sasson emphasizes that he still supports a hard upper limit on the Bitcoin supply and that an annual inflation of 4% is roughly in line with global population growth.

Bitcoin’s fixed supply limit has always been a core element of its appeal. This feature reinforces the “digital gold” narrative and aligns with the principles of Austrian economics, where a fixed money supply serves as protection against monetary inflation and, in theory, helps preserve purchasing power over time. Many Bitcoin proponents argue that altering this limit detracts from what makes Bitcoin so unique.

Moreover, proponents of the existing model point out that the loss of private keys benefits the dynamics of supply and demand. An example of this is Michael Saylor, the chairman of Strategy, who plans to destroy his Bitcoin keys after his death as a “pro-rata contribution” to other Bitcoin holders. This makes their holdings scarcer and potentially strengthens the value of Bitcoin as an end good.

The reactions to Ben-Sasson's proposal were firm and characterized by deep concern. A user on X argued that Bitcoin can be divided into 2,1 quadrillion base units, the so-called satoshis, to refute Ben-Sasson's claim that there would be insufficient Bitcoin “to go around.” The opposite, however, was argued by Ben-Sasson, who noted that these units would also tend toward zero over time due to lost keys.

Critics pointed out that raising the fixed supply limit would bring Bitcoin into line with other cryptocurrencies, which often do experience inflation. Ben-Sasson responded that Bitcoin's scarcity would remain intact as long as the inflation rate remains fixed.

Bryce “Zooko” Wilcox, the founder of Zcash, suggested that Bitcoin developers take a close look at a proposal currently being considered within the Zcash ecosystem. This privacy-focused network community, which also relies on mining for network security and has a fixed supply limit of 21 million Zcash (ZEC), has presented the “Network Sustainability Mechanism.” This proposal offers ZEC holders the option to burn their tokens, after which they would be gradually reissued as block rewards over a period of four years, without increasing the hard limit on the supply of ZEC.

However, for such a change to take place in Bitcoin, consensus is required among developers, miners, and node operators, which remains a challenging task given Bitcoin's decentralized governance model.

Frequently Asked Questions

What are the implications of raising the Bitcoin supply limit?
Raising the supply limit could undermine Bitcoin's scarcity, an essential characteristic that attracts investors, and could reduce confidence in Bitcoin as a safe asset.

How do private key losses relate to the scarcity of Bitcoin?
The loss of private keys leads to a reduction in the effective supply of Bitcoin, which, according to proponents, increases scarcity and can strengthen long-term value.

What can the Bitcoin community learn from the Zcash proposals?
The Bitcoin community could consider exploring innovative mechanisms that preserve economic incentives for miners without sacrificing scarcity, such as the mechanism proposed by Zcash.
