One Weird Trick Could Save Ethereum From Drowning in Zero-Knowledge Proofs 😼

by

The snow has begun to fall thickly around Ethereum, and, as always, everyone sits in the drawing room pretending not to notice the chilly draft sneaking in under the cryptographic door. Zero-knowledge proofs—ZKPs, as they are affectionately abbreviated by those who relish abbreviations—are poised to multiply until they crowd every virtual sofa and armchair. By 2030, estimates suggest we’ll see 90 billion ZKPs each year. At this rate, Ethereum’s main chain, despite all its celebrated innovations, risks playing the part of the elderly aunt who tries valiantly but just can’t keep up at the dance. Gas fees soar, block space shrivels, and the excess of proofs makes one long for a quieter evening. It’s like pouring the Caspian Sea through a samovar.

An Invitation to an Overcrowded Soirée

ZKPs used to be the domain of secretive intellectuals, but now they mingle in every parlor—privacy coins, DeFi, dApps, even mobile phones pass around proofs like business cards. Protocol Labs, armchair prophet to the blockchain gentry, predicts a sky-darkening storm of 90 billion proofs by 2030. The tea leaves have rarely been clearer.

And yet, Ethereum, that over-burdened host, cannot keep up. Give it all the gas units you like—30 million per block, or a respectable measure by any standards—but even then you could only verify about 150 million proofs annually (leaving 89.85 billion proofs politely knocking at the window in the rain). Not exactly a roaring “all are welcome” sort of affair.

So, the options: either halve the estimates and admit defeat by degrees, or resign oneself to the fact that, at $10 per proof, we’ll soon be bartering proofs for kidneys. The roadmap promises upgrades—ah, the perpetual promise—but at its current pace, the party is over before the hors d’oeuvres appear.

DA Led the Polonaise; Will ZK Proof Verification Learn the Steps?

Our tale, as all tales do, circles back to a parable. When Ethereum threatened to collapse under the weight of its own ambition, the community debated as fiercely as uncles after several vodkas. Some declared, “Everything on-chain, or the world ends!” The practical crowd, meanwhile, embraced alt DA layers—dedicated blockchains slipping transaction data off-chain, sparing Ethereum’s blushes and everyone’s bank accounts.

Now, proof aggregation stands in, as a hastily prepared aspic: hundreds of proofs are stitched together into a single “super proof” for Ethereum. Yes, it saves on costs—just as combining all the leftovers saves dinner—but there are delays, and sometimes the dish arrives cold. Trust is placed in aggregators who, as is often the case, lack both staked tokens and the sort of family honor that invites slashing for malfeasance.

Proofs, Pennies, and Panic

Nostalgia and New Fortunes

Again, it bears repeating: whenever a new solution knocks, the critics cry disaster. Some say moving ZK verification off-chain will collapse trust, as if trust were a crystal vase and not a battered samovar. But the sky held, rollups flourished, and Ethereum is still standing. Aggregators, with their hands in their pockets, already sneak trust assumptions into every transaction. A proof-of-stake verification chain, where tokens are at risk and misbehavior actually hurts, isn’t a demotion—it’s just another branch on the family tree.

Even Vitalik, prophet-in-chief, predicted the ZK revolution. The Dencun upgrade—love it or grumble—proved Ethereum could adapt. Now proof verification must find its own back staircase off the main chain, before the house collapses under the weight of its own guests.

The ZKP Wave: Don’t Wait Until Your Boots Are Wet

The ZKP tide is rolling in, ready or not. The moment a killer app emerges with the magnetism of an ill-fated debutante, Ethereum’s drawing room will overflow. The time to act is now—unless we enjoy repeating the congestion farces of yesteryear.

Early projects like zkVerify are galloping toward the rescue. Those clinging to “monolithic” nostalgia risk being left in the parlor, holding their proofs and wondering why the party’s moved next door.

By 2030, if we’re lucky (or unlucky), 90 billion proofs will reshape web3. All it takes is a bit of courage—and perhaps a good umbrella. Alt ZK verification isn’t just a patch; it’s the next act in Ethereum’s ongoing tragicomedy.

John Camardo spends his days as VP of Product at Horizen Labs, leading zkVerify and trying—sometimes successfully—to herd cryptographers, product managers, and other eccentric souls towards a vision of efficient ZK proof verification. With a rĂ©sumĂ© stretching back to Capital One (where he unearthed more commercial opportunities than should fit in a spreadsheet) and a Bachelor’s in Operations Research and Information Engineering from Cornell, he’s been climbing the ranks from Product Manager to VP while plotting the scalable, cryptography-powered chess moves that keep the rest of us from sleeping too soundly. At parties, he’s likely to start talking about privacy, proof systems, and perhaps where to get the best coffee in Ithaca.
