You don't get security for free. You get it at a discount — if the market is feeling generous.
Galaxy Research's Lucas just asked the question every PoS validator hopes nobody ever quantifies: how many newly minted tokens does a chain actually need to defend itself? Is the inflation schedule still worth it, or is it a subsidy wearing a security decal?
Two Layer-1s. Two security budget models. One uncomfortable overlap.
Ethereum balances issuance against fee burn in a dynamic circuit. Solana prints SOL at a fixed diminishing rate to keep its validator set fed. Both are now under the same institutional microscope. The market has already digested roughly a fifth to a third of this debate through weak ETH/BTC and SOL/BTC ratios. What happens when the full implication gets priced is another trade entirely.
Security isn't abstract. It has a balance sheet. Someone is finally reading the line items.
Every PoS chain runs a quiet inflationary machine. New tokens are minted and paid to stakers in exchange for network defense. Call it defense spending denominated in native coin.
Ethereum thought it had solved the budget problem. EIP-1559 introduced fee burning in 2021 — a counter-inflationary circuit that, during peak activity, made ETH net deflationary. "Ultra-sound money" entered the vocabulary. The narrative held for roughly three years.
Then Dencun shipped in March 2024. Blob space gave Layer-2s cheap data availability, and L2 activity exploded. The unintended consequence: mainnet gas demand collapsed. The burn mechanism, starved of fuel, stopped offsetting issuance. ETH flipped from deflationary to net inflationary at roughly 0.5% to 1% annually. Not catastrophic in absolute terms. Catastrophic in narrative terms. "Digital gold" doesn't have a mint running at half speed.
Solana never had that problem. It engineered around it.
Sub-cent transaction fees are the user value proposition. Validators need income. So SOL inflation starts around 8% and decays toward a 1.5% target. The protocol is explicit about its security pricing. Token holders eat the bill every epoch.
Solana's staking participation runs over 50% — among the industry's highest. Issuance changes hit a massive fraction of token holders directly. The social contract around inflation runs deep there.
The asymmetry: Ethereum's security budget is partially self-funded through fee burn. Solana's is almost entirely printed. Galaxy's supply-pressure flag points at both chains, but the dependencies differ in kind, not just degree. Timing matters, too. A research note from an institution with market-making DNA is not an academic curiosity. It's positioning. Clients get asked about inflation schedules in the same breath as OTC flows. The narrative lands fast.
Here's the part that doesn't make the headline. Lucas isn't proposing a technical upgrade. He's questioning the foundational assumption of PoS security economics: that inflation buys security at a fair exchange rate.
Decompose the logic.
The diminishing marginal return problem.
PoS security scales with the dollar value of tokens at stake, not the token count. Issuance therefore has a usefulness ceiling. The first billion dollars of new issuance buys meaningful attack cost. The tenth billion buys validation of the status quo. When issuance starts rewarding early stakers more than it protects the chain, the security budget stops being a budget and becomes a subsidy program.
Galaxy's framing — "how many tokens of security budget are needed to ensure on-chain safety" — is an implicit admission that the marginal security dollar is losing purchasing power. My own audit work on PoS economic parameters confirms the pattern: chains overpay for security during growth phases, then discover the overpayment when markets cool. The EIP-1559 debate in 2021 followed the same arc.
Ethereum's post-Dencun forensic problem.
Let me be precise. Dencun didn't break Ethereum's burn mechanism. Dencun restructured where value flows. L2s pay cents for blob space that previously required substantial mainnet gas. Ethereum's security budget still functions — but its revenue source dried up.
In the weeks after Dencun, I ran daily scripts pulling issuance and burn data off the beacon chain. The pattern was unambiguous: burn rate collapsed roughly 90% from pre-Dencun peaks while issuance stayed flat. The supply curve stopped flexing. The "ultra-sound money" chart became a history lesson in real time. Galaxy's note is the institutional confirmation of what the data showed in Q2 2024.
Less burned. More issued. Net supply creeps up. The L2 ecosystem rides on a security infrastructure it doesn't fully fund. That's the hidden subsidy in Galaxy's critique. L2 success and Ethereum's supply problem are the same phenomenon wearing different labels.
If Ethereum cuts issuance further, the offset is straightforward: less new supply, lower staking APR, thinner margins for Lido, Rocket Pool, and every liquid staking derivative. The counter-inflation circuit strengthens. But validator churn appears at the margin — the kind of churn that matters when the bull narrative depends on stability.
Solana's structural trap.
Solana cannot simply cut inflation without confronting its own architecture.
Validators live on issuance because fees barely register. Cut issuance, small validators exit first. The network concentrates further. Security weakens exactly when the supply-side narrative improves. The bind is architectural: SOL's value proposition is "cheap and fast." Cheap means no fee income. No fee income means issuance. Issuance means supply pressure. Supply pressure hands the store-of-value conversation back to Bitcoin.
The redistribution friction is sharper too. An ETH issuance cut moves value from stakers to holders — a gentle transfer. A SOL cut hits a validator ecosystem that's already concentrated, risks exit spirals, and destabilizes the staking layer that secures the network. The failure mode for Solana is Argentina-shaped: slash the subsidy, lose the infrastructure, watch confidence cascade.
The valuation wave.
The deeper signal is where this conversation happens. Galaxy is institutional infrastructure. When an institution weighs security costs against token value, it applies an equity framework to utility networks. Token issuance becomes dilution. Security budgets become operating expenses. "Supply per active user" becomes a proxy for earnings discipline.
That's a maturation signal. But maturation trades both ways. Institutions that model dilution benchmark against Bitcoin's fixed cap. Galaxy doesn't mention BTC here — it doesn't have to. The question "is ETH supply too high?" carries its own benchmark, and that benchmark has a 21-million-coin hard ceiling.
ZK proofs don't secure networks. Economics do. Proof overhead and security budgets are both line items. Both get audited eventually.
Now the part retail is getting wrong.
The consensus read: "Institutions want lower inflation. Bullish for ETH and SOL."
That misreads how this market prices expectations.
If the discussion stays in research purgatory, the impact is volatility, not direction. If it graduates to a formal proposal, the EIP-1559 playbook applies: expectation-driven run-up, then a sell-the-news dump when the upgrade lands. The asymmetry isn't in the trade's direction. It's in the governance path.
Watch the intermediaries. Lido, Rocket Pool, Jito, Marinade — liquid staking layers extract a percentage of issuance. A supply cut is a revenue cut for every one of them. They will lobby. Quietly, strategically, effectively. Solana's governance history shows validator coalitions can stall or reshape economic proposals for years.
The other blind spot: what security actually costs. PoS security is dollar-denominated, not token-denominated. If issuance drops and the narrative lifts price, the dollar security budget rises. But if the market reads "let's discuss supply" as an admission of bloat, the price reaction goes perverse — the acknowledgment itself triggers selling. Outcome depends less on proposal text than on the governance theater surrounding it.
There's a quiet regulatory dimension too. A transparent, community-driven inflation review strengthens Ethereum's commodity arguments. An opaque foundation-driven adjustment on Solana feeds the SEC's "centralized control" narrative. The how matters as much as the what.
And the deepest irony sits outside this debate. Bitcoin's security budget is paid in electricity, not printed coins. It never has to ask the inflation question. That's why the scarcity narrative keeps winning — every other chain is still negotiating its own.
Code is law, but gas fees are the reality.
Three signals for the next quarter. Does Galaxy's note climb into an ACD discussion? Does the Solana Foundation signal openness to a SIMD recalibrating issuance? How do the LSD protocols respond — their public tone telegraphs the private outcome.
Expect headline spikes. Don't expect unilateral moves until governance makes it real.
Track the token calendars closely. Any whisper of a SIMD or EIP draft will surface in on-chain vote weight before it surfaces in headlines.
This report is a beat, not a hammer. If you're positioned in ETH or SOL, you're long governance maturity — a softer bet than most traders realize.
The market is about to learn whether "security budget" is an accounting term or a weapon. Either way, someone has started counting.
