- Zcash founder Bryce Wilcox suggested a "Network Sustainability Mechanism" as a potential alternative.
StarkWare CEO Eli Ben-Sasson has proposed replacing Bitcoin's fixed 21 million coin supply cap with a 4% annual inflation rate. Ben-Sasson argued on X that the current cap is illogical because private keys are lost over time, diminishing the usable supply as time progresses.
He suggested that a 4% annual issuance rate would roughly correspond to the growth of the human population. This proposal challenges Bitcoin's long-standing narrative as 'digital gold,' which relies on its scarcity to preserve purchasing power. Many Bitcoin proponents view the fixed cap as a fundamental aspect of Bitcoin's uniqueness.
Ben-Sasson's idea was met with significant backlash. Critics pointed to Bitcoin's divisibility into 2.1 quadrillion satoshis, arguing there would be enough Bitcoin to go around. However, Ben-Sasson countered that these units would also trend towards zero due to lost keys.
Some opponents argued that altering the cap would make Bitcoin similar to other cryptocurrencies. Ben-Sasson maintained that scarcity would be preserved if the inflation rate remained fixed. Zcash founder Bryce Wilcox suggested that Bitcoin developers consider a "Network Sustainability Mechanism" similar to one being explored for Zcash, which aims to maintain a fixed cap while reissuing burned tokens to support miner incentives.
