Ethereum's Decentralized Vision Stalled by Scale Challenges

On July 30, 2025, Ethereum will mark a decade since its mainnet launch, a significant milestone in the industry. Ethereum introduced the concept of smart contracts, allowing users to participate in systems that are owned by everyone and no one, with rules written in code that cannot be arbitrarily changed. This vision promised a utopian future where users own their data and software is maintained by a network rather than a boardroom.

However, nearly ten years on, the dreams of a Web3 version of Amazon, eBay, Facebook, or TikTok have not materialized and are nowhere on the horizon. Ethereum co-founder Gavin Wood and ConsenSys founder Joe Lubin envisioned Ethereum having a pervasive influence on communications and information infrastructure. Journalist Jim Epstein predicted that services offered by companies like Facebook, Google, eBay, and Amazon would be provided by distributed computers. Vitalik Buterin himself envisioned Ethereum supporting various applications, including law, cloud storage, prediction markets, and even Skynet, the fictional artificial neural network from the Terminator films.

The primary barrier to achieving this vision is scale. Successful consumer applications today serve hundreds of millions of users, processing trillions of messages and billions of transactions annually. Ethereum processes about 14 transactions per second, while Solana can handle over 1000. The math doesn’t work for decentralized applications that require high throughput and speed.

For example, a decentralized eBay would demand far more than simple payments. Every listing creation or update would require on-chain transactions for item metadata, pricing, and condition details. Auctions would need automatic bidding resolution with time-locked smart contracts. Escrow systems would have to hold funds until delivery confirmation, with DAO arbitration for disputes. User reputation systems would require immutable rating storage tied to wallet addresses. Inventory management would need real-time stock tracking, possibly through tokenized goods. Shipping confirmations would demand oracle integration for delivery proofs. Marketplace fees and tax royalties would need smart contract enforcement. Optional identity verification systems would require decentralized credential management. Each interaction would multiply the transaction load exponentially beyond what current infrastructure could support.

It goes without saying that this would require a blockchain of unprecedented speed and throughput. Frankly, a decade after Ethereum, the infrastructure just hasn’t been there to support it. The business model hasn’t always made sense either. Modern applications need massive scale to generate revenue that covers development costs. Furthermore, layer 2 solutions fragment users across platforms, defeating the purpose of building unified global computing.

This isn’t theoretical. OpenSea struggled with profitability despite dominating NFT trading with high-value transactions and fee-tolerant users. If you can’t profit from selling digital art to crypto enthusiasts paying hundreds in fees, how do you build a marketplace for used goods? The economics are even worse for lower-value transactions that define mainstream commerce. A decentralized social network charging $5 per post would be dead on arrival. Gaming applications that require a few dollars in transaction fees for every item trade won’t attract players who expect the same for free elsewhere. So far, the only viable on-chain businesses have been those that can extract massive value from relatively few users – essentially high-stakes financial applications and speculative trading.

The industry accepted a false tradeoff: security and decentralization, or functionality and scale, but not both. But transaction throughput has steadily increased across networks as the technology matures. We can now achieve massive scale even with proof of work chains, maintaining the security and decentralization that made blockchain revolutionary in the first place. Zero-knowledge proofs allow users to prove transaction validity locally, submitting only small cryptographic proofs that are aggregated recursively and in parallel by a network of provers. Networks can process millions of transactions without every node verifying each one individually. When users prove their own transactions, the marginal cost of adding an additional transaction approaches zero, and blockchains can finally support the economics that mainstream applications require.

However, ten years on, it’s clear that the vision once laid out by the futurists of Web3 has moved at a disappointing pace. Let’s hope the next decade moves a little faster – and, fingers crossed – our blockchains too.

Carter Feldman, CEO of Psy Protocol, highlighted the throughput issue, stating that our blockchains simply can’t handle the throughput required for large-scale decentralized applications (DApps). This limitation has prevented the development of on-chain versions of major platforms like Amazon or eBay, despite the ambitious visions laid out by Ethereum’s founders and supporters.
