Eli Ben-Sasson, Zcash founder and and CEO of StarkWare, the corporate behind Ethereum Layer 2 scaling resolution Starknet, publicly argued that Bitcoin 21 million provide cap “doesn’t make sense.” He’s additionally proposing as an alternative that the community undertake a tough ceiling on the annual issuance price.
Ben-Sasson’s core argument facilities on key loss. As a result of non-public keys are completely misplaced over time, the cash hooked up to these keys stay on the ledger however fall out of sensible circulation, making the usable provide unknowable and trending downward. His proposed repair: exchange the fastened total-coin ceiling with a hard and fast inflation price ceiling. His particular determine was 4% per 12 months, which he described as “an inexpensive higher sure on human inhabitants enlargement.”
Capping the provision of Bitcoin at 21M doesn't make sense. Beacuse over time, keys will likely be misplaced. Actually, as time goes to infinity, all keys will likely be misplaced.
I strongly assist a transparent financial coverage with an absolute higher sure on the # of Bitcoins sooner or later. Say, repair a max…— Eli Ben-Sasson | Starknet.io (@EliBenSasson) July 7, 2026
The shift is from capping the inventory of cash to capping the annual move of recent issuance, a distinction that sounds technical however carries huge structural implications for each holder who priced Bitcoin’s shortage into their place.

Zcash Co-Founder Proper about Bitcoin?
Alongside the lost-key argument, the Zcash co-founder, Ben-Sasson, flagged Bitcoin miner safety as a compounding concern. The block reward at the moment stands at 3.125 BTC following the April 2024 halving, and it’ll proceed to say no on schedule, ultimately reaching zero round 2140. Because the subsidy shrinks, miners rely more and more on transaction price income to remain economically viable, and a community that can’t maintain miner participation turns into progressively extra susceptible to assault. Ben-Sasson described this danger as “looming giant on the horizon.”

This a part of the argument has real traction amongst protocol researchers, impartial of whether or not one accepts the remainder of Ben-Sasson’s thesis. Bitcoin’s long-run safety mannequin is an actual open query – the belief that price income will totally compensate for the disappearing block reward is unproven at scale. Elevating that challenge doesn’t require agreeing that the provision cap ought to change.
The lost-coin case is tougher to quantify exactly. We estimated the efficient circulating cap at roughly 18.5 million BTC as soon as completely inaccessible cash are excluded, with Ledger putting misplaced provide as excessive as 4 million BTC as of late 2024. Roughly 19.9 million BTC have already been mined, or round 95% of the eventual complete, leaving solely about 1.1 million BTC remaining to be issued over the following century-plus. The attrition from key loss is actual.

This Received’t Go Nowhere
The governance math is unambiguous. Altering Bitcoin’s provide cap would require a Bitcoin Enchancment Proposal, new shopper software program, and adoption by miners, nodes, and customers. Roughly 97% of Bitcoin nodes at the moment implement the present provide schedule. A cap change just isn’t technically unattainable, however a fork that dilutes shortage would break up the chain and certain destroy a lot of the worth it was ostensibly attempting to protect. The talk round Bitcoin’s position as a strategic reserve asset makes any trace of provide flexibility much more politically poisonous within the present atmosphere.
The neighborhood’s divisibility counterargument can be value understanding exactly. Bitcoin’s 21 million cash subdivide into 2.1 quadrillion satoshis, offering greater than sufficient unit granularity to accommodate adoption at any life like value degree. Ben-Sasson’s rebuttal, that “satoshis would additionally pattern towards zero in absolute phrases if key loss continues indefinitely,” is technically appropriate however operates on a timescale measured in centuries, not buying and selling horizons.
This can be a horrible concept. The actual fact that you can imagine altering a protocol constructed round shortage and decentralization. As soon as one main change like that is made then others will come on in and do the identical. You're destroying the thought of what Bitcoin got down to be .Why don't you…

What makes Ben-Sasson’s intervention notable just isn’t its chance of success. It has none. What issues is who’s elevating the argument and why: a distinguished ZK-proof technologist with credibility within the Ethereum ecosystem, citing miner safety degradation because the mechanism that would ultimately drive the dialog.
