Galaxy Research's Lucas just asked a question that reads like an academic footnote but lands like a cold front over the entire proof-of-stake ecosystem: how many tokens does it actually take to secure a network — and is the current inflation issuance schedule worth the cost? The framing is deliberately open-ended. No proposal. No code change. No hard number. Just a question. That makes it more dangerous than any announcement. A proposal can be debated, amended, and killed in committee. A question lingers in the mind of every institutional allocator reading the note, and it metastasizes into assumptions about supply, dilution, and fair value.
The timing is not neutral. We are deep into 2025, and ETH has spent the better part of a year underperforming bitcoin while its supply narrative flipped from deflationary "ultrasound money" to a slow but persistent net issuance. Solana, the high-beta darling of this cycle, carries an inflation profile that makes Ethereum look positively austere. When a major institutional research desk starts publicly circling "supply" as an open problem, it's not an intellectual exercise. Clients are asking hard questions. Tracing the noise floor to find the alpha signal.
The Model: Inflation as a Security Purchase
Both networks are running a variation of the same playbook: mint new tokens, distribute them to validators, and call the result a security budget. The logic is straightforward enough. Inflation is the price of security. Fresh issuance funds staking rewards. Staking rewards attract validators. Validators make the chain expensive to attack — the cost of an adversarial takeover is roughly the amount of tokens an attacker must accumulate and stake. You are literally buying attack resistance with dilution.
Ethereum added a second mechanism on top of that: EIP-1559 fee burning. When mainnet activity peaked, the burn offset issuance entirely, and ETH went net deflationary. That produced the "ultrasound money" narrative, the story that carried institutional interest through 2021 and 2022 and into the ETF approval cycle. It was a beautiful self-contained economic narrative: usage creates fees, fees burn supply, scarcity drives value, value funds security.
Then Dencun shipped. Blobs gave Layer2s cheap data availability, L2 activity exploded, and mainnet fee burn collapsed. The burn mechanism still exists, but it's a shadow of its former self. Ether is now in a regime of modest net issuance — roughly 0.5% to 1% annualized, depending on activity. The technical trigger for Galaxy's discussion is hiding in plain sight: the protocol's own scaling roadmap eviscerated its deflationary loop. Code does not lie, but it does hide.
Solana runs a different architecture with the same dependency. High starting inflation, a decaying schedule targeting 1.5% long-term, staking yields around 6-8% — nearly all of it paid from issuance. The "cheap and fast" value proposition means transaction fees are negligible, pocket change that couldn't cover validator payroll even in a bull market. Solana's security budget is issuer-funded, period. There is no burn mechanism to soften the story. It's the purest PoS inflation model operating at scale in the industry today.
The asymmetry is the story. Ethereum has one foot in the old deflationary era and one foot in the post-Dencun inflation regime, which makes its economic identity ambiguous. Solana is straightforwardly dependent on new token supply for its security and its validator incentives. When Galaxy asks whether inflation schedules should be revisited, the two networks enter the conversation from opposite ends of the spectrum.
The Validator Math Nobody Wants to Do
The core of Galaxy's framing — security budgets should be evaluated against token value — is theoretically elegant but operationally loaded. Let me do the arithmetic that usually gets skipped.
Attack cost is not measured in token count. It's measured in market value. A network with 100 million tokens at $100 each carries a larger attack threshold than a network with 1 billion tokens at $5 each, even if the latter has five times more tokens staked. The moment you accept this framing, the inflation logic begins to crack. If issuance is a security purchase, what matters is not how many new tokens you mint, but whether the market value of those tokens actually increases the cost of an attack by a meaningful margin.
That's the marginal efficiency problem. At 28-30% staking participation, Ethereum has already achieved broad stake distribution. Adding more issuance to push participation to 35% will not meaningfully increase attack costs — the additional validators are marginal, and their contribution to overall security is marginal. But the dilution cost is paid by every ETH holder in proportion to their holdings. More tokens are being spent to buy the same defensive plateau.
Solana is worse. Staking participation is already north of 50%, one of the highest in the industry, but heavily concentrated among large validators and institutional stakers. Cutting inflation would directly cut the income of those validators. Some smaller operators would exit, and the remaining set would consolidate further. Decentralization decays. That's a security downgrade, not a cosmetic side effect.
Based on my experience auditing validator economics during the DeFi summer and the years of boom-bust cycles since, this is the classic principal-agent trap. Validators are not naturally aligned with token holders. They are aligned with yield. Any proposal to cut inflation must wrestle with the fact that the people securing the network are economically hostile to the change. The "stakeholders" Galaxy's note references are not a unified group with a shared interest — they are a coalition with divergent payout schedules.
The Solana Spiral Path
The grim scenario follows a mechanical logic. Cut Solana's inflation, and validator earnings drop. Marginal validators exit. Network concentration increases. Confidence wobbles. SOL price dips as the market prices in diminished staking demand. The fiat value of remaining validator rewards drops further. More validators exit. It is a slow-motion spiral — not a cliff, but a descending staircase. Not guaranteed, but structurally possible.
The bullish counterargument is that real usage growth eventually picks up the slack. Solana's meme ecosystem, DePIN projects, and fee-generating applications are producing genuine activity. But "eventually" is not a security model. Redundancy is the enemy of scalability, but so is fragility. A network that cannot pay its defenders without printing money has a cost structure problem, not a narrative problem.
The L2 Free-Rider Problem
Here is where my Layer2 research lens kicks in, because the Galaxy discussion has an unstated target: the L2-centric roadmap itself.
The blob economy is doing exactly what it was designed to do — making Layer2 transactions nearly free. But the side effect is that ETH's burn mechanism has been neutered. Fee activity that once flowed to the mainnet and burned supply now happens on L2s, where it neither burns ETH meaningfully nor contributes to protocol revenues. The security costs of the mainnet are subsidized entirely by mainnet users and ETH holders. Layer2s are, in a structural sense, free-riding on security they do not pay for.
This is the connection Galaxy's note gestures toward but never names. If you reduce Ethereum's issuance, you change the economics for every L2 that settles on it. The implied discussion is not just "should ETH have a smaller inflation schedule" — it's "should the ecosystem that scales on top of Ethereum be expected to contribute to the security budget it depends on." So far, that ledger has no entry for L2s.
What's Missing From the Debate
The contrarian blind spot in Galaxy's framing is treating "security budget" as a static variable. It is not. Attack cost scales with token value, not token count. If you cut issuance and the market reprices the asset upward, security can improve even as the issuance rate falls. That's the clean version of the thesis. But it requires markets to actually reward the change with a higher valuation, and that is not guaranteed. Inflation cuts are not automatically price-positive. They trigger a redistribution between stakeholders — validators and LSD providers lose, non-staking holders gain — and the net market reaction depends on which cohort has more marginal buying power.
The second blind spot is governance. Ethereum's inflation parameters flow through core developer coordination, client upgrades, and a slow consensus process. That's heavy, but transparent. Solana's path goes through SIMD governance proposals — there is precedent there, including a 2023 adjustment to staking returns. But the Solana Foundation retains outsized influence over the process. If inflation is cut through a Foundation-driven initiative without broad community participation, it feeds the "centralized control" narrative that US regulators have already been circling around SOL. The Howey question hinges on whether token value depends on the managerial efforts of others. A top-down economic adjustment is exactly the kind of evidence a plaintiff's lawyer wants.
The Read
The market has already partially priced this in. ETH's persistent underperformance against BTC is, in part, a supply narrative discount. SOL's high-beta posture means uncertainty gets amplified in both directions. Galaxy's note is a confirmation signal, not a fresh shock. The real question is whether this becomes a formal proposal within the next twelve months.
Historical analogy: EIP-1559 discussions drove ETH up on expectations through 2020 and 2021, and the actual implementation triggered a sell-the-news event. If inflation discussions move toward concrete proposals, expect a similar pattern. Buy the speculation, sell the activation.
And if nothing happens? If the discussion stays in research notes and never reaches proposal status, the market learns that supply concerns at the leadership level are real but unactionable. That weakens both assets. By extension, it strengthens bitcoin's fixed-supply dominance. The absolute scarcity of BTC is the benchmark against which this whole debate is being judged. Nobody has ever had to ask whether bitcoin's issuance schedule deserves revisiting. That is the quiet comparison underneath every word of Galaxy's note.
The Takeaway
Galaxy's question is not a call to arms. It's a recognition that the PoS security budget model has a maturity problem. Inflation as a security mechanism worked while networks were growing into their token valuations. It becomes a liability when stakeholders start asking what they're getting for their dilution.
I've audited enough incentive structures to know that when validators and token holders diverge, the network has a governance problem, not a math problem. The next 6 to 12 months will tell us whether Ethereum can route around its LSD lobby, whether Solana can cut issuance without triggering a validator exodus, and whether either network can graduate from "growing at any cost" to "valuable at the right price."
The bill for security is printed in new tokens. Someone eventually has to check the price. Volatility is the price of entry, not the exit.
