Ethereum Promised a ‘World Computer’—But Here’s What It Actually Became
Share
Key Takeaways
Ethereum’s world computer dream choked at 15 TPS. Scaling only happened when it stopped doing everything itself.
The Merger made Ethereum clean but didn’t make it fast. Layer-2s now carry the weight.
DeFi and NFTs are still cornerstones of Ethereum.
Ethereum has never stopped and it is still developing.
Ethereum’s original vision was to create a “world computer” that would decentralize everything, from finance to governance to identity.
Now it is celebrating its 10th anniversary. Let’s see if it has it delivered on that promise.
In 2015, Ethereum introduced a new kind of blockchain. One that wasn’t limited to recording transactions. It let developers write programs, smart contracts, that would run exactly as written, on a decentralized network.
Vitalik Buterin proposed a programmable foundation for building applications that don’t rely on central servers or trusted intermediaries. The goal was to create public infrastructure for a digital economy that anyone could access and no single entity could control.
A decade later, Ethereum has reshaped finance and digital ownership, but not in the way its early supporters imagined. This article looks at what it built, what it couldn’t, and where it’s headed next.
Ethereum’s ‘World Computer’ Vision
Vitalik Buterin published the Ethereum whitepaper in 2013, he was only 19 years old. He had contributed to Bitcoin development but wanted more than a payment network.
He thought Ethereum would let people write software that runs on a blockchain, with no need for a central server or company. He wanted to build an open decentralized system where anyone could deploy code, and no one could take it down or change the rules.
Ethereum introduced smart contracts, which are programs that carry out instructions automatically, once predefined conditions are met. These aren’t hosted by companies or platforms.
They run across the network and stay there. Ethereum’s programming model allowed developers to build anything they could describe in logic, from auctions to loans to multiplayer games. The system was designed to be flexible enough for any use case.
The ICO Boom and Early Expectations
Developers and early adopters saw Ethereum as a way to break free from gatekeepers. By 2016, projects were already raising money directly from users by selling tokens. These Initial Coin Offerings (ICOs) exploded in 2017, with more than $20 billion raised. The process was fast, global, and mostly unregulated.
The Technical Reality of Ethereum
Ethereum promised to be the world’s decentralized computer. What it became, at its core, is a bottlenecked powerhouse: flexible, green, and programmable, but slow, expensive, reliant on L2s for scalability, and unevenly accessible.
Scalability Challenges
The biggest problem was scale. The Ethereum base layer handles around 15 transactions per second (15 TPS), while theoretically, Visa can process over 24,000.
When traffic surged, the network jammed. That limitation, throughput, became Ethereum’s Achilles’ heel.
4/ As Ethereum looks ahead to the next 10+ years, challenges like scalability serve as a reminder: the unknown can be a driver of innovation.
Gas fees, which are paid to miners and validators to process transactions, went up sharply.

Peak gas fees during extreme congestion (e.g., NFT drops) could hit $100–$200 and the average was around $50. This meant that sending $50 often meant paying another $50 just to push it through. The problem made headlines. It pushed users away and exposed a hard truth: Ethereum was expensive.
By July 2025, layer-2 solutions like zkSync and Starknet keep costs below $1 for most users, though base-layer congestion can still sting during major events.
The Ethereum Virtual Machine (EVM)
At the center of Ethereum is the Ethereum Virtual Machine (EVM). The EVM is what makes smart contracts work. It’s the environment where decentralized apps (dApps) run and where money moves automatically. It is Turing-complete, which means it can run any logic that can be mathematically written.
That’s powerful, but costly. Every step, every function, every byte stored comes with a price in gas. Running a simple smart contract is fine. Running a complex app or financial product can turn into a hundred-dollar interaction. This pushed developers to cut features, simplify ideas, or look for cheaper environments.
This architecture may not stay forever. A 2025 proposal by Vitalik Buterin suggests replacing the EVM with RISC-V, a simplified instruction set that could improve efficiency, especially for zero-knowledge proofs. The plan remains under debate but signals a possible shift in how Ethereum runs smart contracts.
The Merge in 2022 slashed Ethereum’s energy use by 99.95%, making it a green giant in blockchain.
While PoS improved sustainability and lowered barriers to entry, it raised new concerns. Validator power became concentrated in large staking pools, exchanges, and liquid staking. These concerns sparked ongoing debates about centralization and long-term governance.
Ethereum’s developers continue to explore solutions, including distributed validator technology and protocol-level decentralization tools.
Layer-2 Rollups and Sidechains
Layer-2 rollups and sidechains moved transactions off the main Ethereum chain. Rollups like Optimism, Arbitrum, zkSync, and Starknet batch transactions and post only proofs to Ethereum.
This maintains Ethereum’s security while slashing costs. According to L2Beat, layer-2 networks now process more transactions daily than Ethereum itself.

This changed Ethereum’s meaning as a world computer. It no longer runs everything. Instead, it acts as a secure base, while faster, cheaper networks handle the activity above it.
3/ Today, there are many rollups that are scaling the ecosystem without compromising security or decentralization.
As a result, Ethereum evolved, offloaded work, and became modular, meaning its functions are separated into specialized layers rather than handled all in one place. Instead of one chain doing everything, Ethereum now anchors many layers. That shift, from monolithic dream to layered infrastructure, is what made it viable.
Key Ethereum Updates Timeline
Ethereum has already evolved from a simple smart contract platform into the backbone of decentralized finance and Web3. With the Merge, Dencun, and most recently Pectra, Ethereum has achieved major milestones in scalability and usability. But the roadmap doesn’t stop here.
The next set of upgrades aims to make Ethereum faster, cheaper, and easier to use — for both everyday users and developers building on top of it.
Frontier (July 30, 2015): Launch of Ethereum mainnet with Proof‑of‑Work and smart contract functionality.
Berlin (April 15, 2021): Gas optimizations and new transaction types.
London (August 5, 2021): Introduced EIP‑1559 fee burn and improved fee mechanics.
Verge: Introduction of Verkle trees to simplify Ethereum node requirements, improving scalability and decentralization.
Purge: Reduction of historical blockchain data storage, lowering hardware requirements for validators.
Surge: Full sharding rollout to massively increase throughput and lower transaction fees.
Splurge: Miscellaneous upgrades focused on fine‑tuning features and developer experience.
What Ethereum Became: The Financialization of Everything
Ethereum didn’t decentralize everything. Instead, it became a global platform for trading, lending, and investing.
DeFi Took Over: Lending, Trading, Staking, and More
Ethereum decentralized finance (DeFi) protocols redefined how people interact with money. Decentralization was essential and drove adoption. For example:
Uniswap enabled permissionless trading: Users could swap tokens directly from their wallets without using a centralized exchange.
Compound and Aave introduced crypto lending and borrowing: Users earned interest on deposits or borrowed against their crypto holdings without a bank.
Sky powered decentralized stablecoins: It allowed users to mint DAI, a stablecoin backed by overcollateralized smart contracts.
Composable finance flourished: Users stacked strategies across protocols, borrowing on one, trading on another, and staking elsewhere, without intermediaries.
Ethereum became a 24/7 global financial system: Millions participated, pushing the network to its technical limits.
Over $83 billion is locked in DeFi by mid-2025: This figure highlights the scale of decentralized finance and its real-world utility beyond speculation.
This activity pushed Ethereum to its limits and set the tone for what kind of platform it had become.
NFTs and Speculative Use Cases
The non-fungible tokens (NFT) boom has a rich history and big consequences. In 2021, Ethereum became the home of NFTs. Artists and developers minted unique digital items such as images, videos, songs, and even poems using a token standard called ERC-721.

Projects like CryptoPunks and Bored Apes turned into status symbols.
Beeple, one of the most well-known for surreal, internet-themed work, sold Ethereum-based artwork for $69 million through Christie’s.
New collections launched weekly, driving millions in volume.
People traded cartoon animals and pixel art as if they were rare antiques.
The frenzy brought mainstream attention. It also brought serious volatility.
As a result, Ethereum’s image shifted. For a while, it wasn’t the “world computer.” It was where people traded jpegs for six figures and the platform many used to get famous by building strong communities.
However, in 2025, NFTs remain cultural cornerstones, with new use cases like tokenized real-world assets (RWA) gaining traction. For example:
BlackRock: Their BUIDL fund, a tokenized U.S. Treasury on Ethereum, hit $2.5B+ in assets.
Franklin Templeton: Tokenizing bonds and funds on Ethereum, they’re boosting liquidity and opening DeFi access for investors.
PayPal: PYUSD, their dollar-pegged stablecoin on Ethereum, powers fast, borderless transactions..
Gas Wars and Cost Barriers
Ethereum’s growth spiked gas fees, with users competing for limited block space.
NFT drops and token launches drove transaction costs above $100.
You might ask: Was Ethereum a platform for the wealthy? There are some key elements to consider:
Complex DeFi transactions, like loans, often cost even more, hitting wallets hard.
Small users were priced out, making casual participation nearly impossible.
Critics called Ethereum a whale’s playground, favoring deep-pocketed traders.
Developers introduced EIP-1559 to burn ETH and stabilize fees, plus layer-2 solutions like Optimism.
Despite reforms, base-layer costs remained high, limiting accessibility.
Bad take. I don't want Ethereum to only be used by wealthy people and honestly that's how it seems right now. I'd love for non-whale trading on Ethereum, but we need to move much of our activity to L2s.
It's stupid to say our ecosystem is vibrant based on dollar amounts. https://t.co/8arWmm3gbI
At its peak, Ethereum felt less like an open protocol and more like an elite financial arena.
DAO Evolution: From Hack to Governance Experiments
Ethereum’s early vision of decentralized governance was tested in 2016 with The DAO, a community‑run venture fund that was famously hacked, leading to a contentious hard fork. That event shaped Ethereum’s approach to governance, spawning a wave of decentralized autonomous organizations (DAOs).
Today, DAOs manage billions in DeFi protocols, NFT communities, and even real‑world assets, experimenting with on‑chain voting, treasury management, and decentralized decision‑making.
Ethereum Culture & “Ultra Sound Money”
Post‑EIP‑1559 (2021), Ethereum began burning a portion of transaction fees, reducing net ETH issuance. Combined with staking, this created the “Ultra Sound Money” meme, positioning ETH as potentially deflationary, contrasting Bitcoin’s fixed supply narrative. This cultural shift reframed ETH from a “gas token” into a store‑of‑value asset underpinning Ethereum’s evolving financial ecosystem.
at the end of the day the thing about ethereum is that it's money at the end of the day – ultra sound money too
Social and Economic Impact: Successes and Failures
Ethereum’s social and economic impact is a mixed bag of breakthroughs and broken promises. Its DeFi ecosystem empowered millions, enabling borderless lending, trading, and earning without banks.

DeFi scale: Ethereum’s DeFi empire soared to $180 billion in TVL by late 2021, fueled by Uniswap and Aave. By July 2025, TVL sits at $84.53 billion, reflecting the impact of market cycles but still showcasing DeFi’s enduring pull.
Creator upside: NFTs democratized digital ownership, turning artists into millionaires.
Cultural hubs: Projects like CryptoPunks built vibrant communities around digital assets.
Cost barrier: In emerging economies, where $50 transactions can equal a month’s income, participation was often speculative rather than practical.
Wealth gap: High gas fees sidelined smaller users, favoring wealthy “whales”
Power dynamics: Governance remains uneven, Ethereum’s upgrades are led by developers and DAOs, but decision-making power concentrates among core contributors and large validators.
Blame cycle: A 2024 study of The DAO collapse called it a “multi-distributed blaming process” where responsibility shifted between developers, the code itself, and Ethereum’s broader ecosystem. The fallout shaped future governance decisions and exposed how fragile decentralized control can be in practice.
Opaque process: Off-chain governance systems, like EIP voting, often feel opaque to average users.
Global spread: Despite the flaws, Ethereum’s open protocol sparked global innovation
Local builds: Developers in countries like India and Nigeria used it for local tools like remittance platforms and supply chain tracking.
Speculation spike: The 2021 NFT boom fueled perceptions of Ethereum as a get-rich-quick space, often overshadowing real-world use.
The broader economic promise, freedom from centralized control, remains, but is still unevenly realized due to cost and access barriers.
Ethereum’s Evolving Role in the Blockchain Ecosystem
Ethereum’s “world computer” dream has shifted toward a more grounded role: the secure foundation for a modular blockchain system.
Ethereum faced competition from high-speed chains like Solana (65,000 TPS). To counter this, it focused on security and decentralization over raw throughput.
Layer-2 rollups like Arbitrum (40,000 TPS) process most transactions. Ethereum’s base layer acts as a trust anchor, validating final results.
This modular structure changed Ethereum’s function. It no longer aims to handle everything on one chain. Instead, it supports a network of faster layers that rely on it for settlement and data integrity.
Interoperability protocols like Polygon and cross-chain tools such as Chainlink’s Cross-Chain Interoperability Protocol (CCIP) allow Ethereum to interact with competing chains. This has turned Ethereum into the backbone of a layered internet. Rollups and sidechains handle scale. Ethereum secures the core.
Competition continues. Solana’s speed and low fees attract NFT and DeFi projects. Avalanche’s subnets offer custom scaling options. Ethereum responds with a scale of its own.
According to Electric Capital, it has more than 200,000 active developers. Ethereum is no longer the only platform. But it is still the most trusted one.
Ethereum’s Quantum‑Resistant Plans
Ethereum recognizes the future threat posed by quantum computing to elliptic curve cryptography (used in ECDSA, BLS, KZG commitments) and is actively preparing. The Ethereum Foundation hasbacked projects like ZKnox, which cut post‑quantum signature gas fees by 12× using lattice-optimized code in Yul, making practical quantum-safe verification possible today.
Looking forward, Ethereum developers are prototyping zk‑STARKs, lattice-based, and hash-based signature schemes to secure network signatures in a post-quantum world. These efforts arepart of a long-term roadmap through 2027 and beyond, ensuring Ethereum remains secure even when quantum attackers become feasible.
🧵1/ Post-quantum Ethereum: preparing for quantum threats to signatures and consensus.
A deep dive into the latest research on signature aggregation, new hash functions, and ZK-based aggregation proofs.
Recap from a talk I gave last week during the beam day in Cannes. 👇
If/when large-scale quantum computers arrive, they could break Ethereum’s core cryptography, exposing private keys and letting attackers forge transactions or hijack validator nodes. This threat is particularly urgent on Ethereum due to its PoS consensus and widespread use of ECDSA/BLS keys.
ECDSA and BLS are cryptographic key systems used in blockchain—ECDSA (used in Bitcoin) is fast and widely adopted, while BLS (used in Ethereum post the Merge, Chia) enables compact signatures and efficient multi-signature aggregation.
By moving toward quantum-safe signatures and enabling account abstraction, Ethereum can allow users to rotate keys, use new signature schemes, and future-proof smart contracts, all without disruptive forks. These preemptive measures help prevent catastrophic asset loss and ensure long-term network resilience.
Impact of MiCA on Ethereum
The EU’s Markets in Crypto-Assets (MiCA) regulation, fully enforced by December 2024, is reshaping Ethereum’s role in Web3. It streamlines compliance across 27 EU states, making it easier for Ethereum-based projects to operate legally.
Stablecoins like PayPal’s PYUSD (initially issued on Ethereum) must now meet strict requirements, including EU banking licenses and full fiat reserves. DeFi protocols such as Aave face new transparency rules, with smart contracts subject to stricter reporting. NFT platforms must verify creators to reduce fraud.
Real-world asset projects like BlackRock’s $2.5 billion BUIDL fund gain clarity under MiCA, drawing institutional interest. Despite new burdens, Ethereum’s layer-2 growth and 200,000+ developer base keep it at the center of regulated decentralized finance.
Conclusion
Ethereum set out to become a decentralized world computer. It laid the groundwork for trustless software, but real-world use steered it toward financial applications. What it built was valuable, but narrower than the original vision.
It didn’t decentralize every system or become the universal base layer for the internet. Instead, Ethereum became the foundation of a modular, layered ecosystem. It powers DeFi, NFTs, and real-world tokenization through faster networks that run on top. Today, Ethereum acts as the security core of the blockchain’s financial stack.
As it continues to evolve, Ethereum’s greatest strength is its flexibility. It didn’t fulfill every ideal, at least not yet, but it adapted without breaking. That resilience is what keeps it alive.
