Crypto Recreated the Middlemen It Promised to Remove
A recent CEPR analysis lands on an awkward truth for crypto: Bitcoin and Ethereum proved decentralized systems can work, but much of the industry has rebuilt trust around new intermediaries instead of eliminating them.
- Bitcoin proved peer-to-peer money is possible.
- Stablecoins shift trust to issuers, custodians, banks, and auditors.
- Ethereum’s block builders and MEV create new control points.
- Tokenization still depends on law, custody, and enforcement.
- South Korea is treating these products like financial infrastructure, not toys.
Bitcoin launched 17 years ago with a radical pitch: money that works without trusted intermediaries. That was never just marketing fluff. Bitcoin still adds blocks roughly every 10 minutes through distributed consensus, and users do not need a bank’s permission to send funds on-chain.
Ethereum widened the ambition by popularizing smart contracts, pieces of code that automatically execute agreements on-chain. That opened the door to a lot of useful experimentation: decentralized finance, tokenized assets, and a long list of financial products that traditional institutions were too slow, too bloated, or too scared to build themselves.
But the CEPR framing is blunt about the catch. Once crypto products touch payments, custody, reserves, or legal claims in the real world, the old trust problem comes back wearing different clothes.
Stablecoins are the cleanest example. Major fiat-backed stablecoins are typically supported by off-chain reserve assets such as Treasury bills, bank deposits, and money market instruments. That means the token is only as credible as the issuer, the custodian, the banking partner, and the auditor standing behind it.
That is not a small detail. It is the whole mechanism.
A stablecoin can be useful and still be structurally centralized. If the issuer can freeze redemptions, lose banking access, misstate reserves, or run into jurisdictional trouble, the blockchain does not fix the problem. It just records it faster.
That is why calling every stablecoin “decentralized money” is nonsense with a nicer font. Fiat-backed stablecoins are better understood as private money instruments with blockchain rails. Useful? Absolutely. Trustless? Not even close.
To be fair, that does not make them bad. It makes them honest. The problem is the branding, not the utility.
The same tension shows up in DeFi, especially on Ethereum. Public blockchains are transparent, which sounds elegant until you remember that transparency can also be exploited. One common abuse is a sandwich attack, a form of on-chain front-running where an attacker places trades before and after a victim’s pending transaction to extract profit from the price move.
That is where Ethereum’s transaction ordering machinery gets interesting. Specialized actors known as builders assemble transaction bundles into blocks. In practice, that means Ethereum’s open market structure can create a new layer of coordination and power around block production, even if the base protocol itself remains decentralized.
So no, builders are not the same thing as a bank. But they are also not invisible. Crypto often replaces old middlemen with narrower, more technical ones. Different jargon does not erase familiar risks.
That is the real lesson here: decentralization is not a slogan, it is a system design problem. Who sets the rules? Who can see the data? Who controls access? Who is accountable when something breaks?
The CEPR analysis argues that trust in crypto does not disappear. It gets anchored somewhere else: in stablecoin issuers, custodians, auditors, oracle operators, block builders, and the legal wrappers around tokenized assets. That is not automatically a fatal flaw, but pretending crypto has escaped intermediaries entirely is childish wishful thinking.
Tokenization makes the issue even more obvious. The pitch is seductive: put real-world assets on-chain and make them easier to trade. Real estate, bonds, equities, vouchers, loyalty points, slap them on a blockchain and, supposedly, liquidity will rain from the sky.
That is the sales pitch, anyway. The reality is messier. A token is not the asset itself. It is a record, a claim, or a representation of a claim. If the on-chain record says one thing and the legal rights off-chain say another, courts, trustees, depositories, and supervisors decide what actually counts.
In other words, the blockchain may be the ledger, but the legal system still has the final say.
That is why tokenization can create disputes faster than it creates liquidity. Markets love the word “liquidity.” Lawyers prefer questions like “who owns this in bankruptcy?” Those two instincts do not always get along.
The South Korea policy debate shows how seriously regulators are starting to take these issues. The reporting referenced in the materials points to a digital asset framework law, a won-denominated stablecoin, tokenized securities, and broader real-world asset tokenization initiatives. That is not fringe crypto theater. That is payment infrastructure, market structure, and financial law being shoved into the same room.
The policy questions are refreshingly plain. Who issues the asset? Who manages ledger operations? Who holds reserves, and in what instruments? Who verifies external data? Who is legally responsible when something fails?
That is the right way to frame it. Not “is it crypto?” but “where does trust sit, and what happens when trust fails?”
A won-denominated stablecoin, for example, would function less like a speculative token and more like part of national payment infrastructure. That means the standards should be tighter, the oversight clearer, and the marketing fluff far less tolerated.
There is also a devil’s-advocate point that crypto evangelists sometimes hate hearing: decentralization can reduce dependence on a single operator, but it does not abolish governance, enforcement, or accountability. In many cases, it just makes those tradeoffs more visible. Freedom is great. So is pretending someone will not have to clean up the mess when the system breaks, until reality arrives with a clipboard.
Bitcoin proved that consensus can happen without a central bank in the middle. Ethereum proved that contracts can run without a traditional clerk stamping every line. But the moment crypto touches reserves, redemption, identity, or real-world property rights, the legal and institutional world comes roaring back in.
That does not mean crypto failed. It means the hard part was never just building a blockchain. The hard part is deciding which parts of trust can be automated, which parts must remain human, and which parts people are still pretending do not exist.
Key questions and takeaways
-
Did Bitcoin remove trusted intermediaries?
Bitcoin removed the need for a central network operator or bank to approve every payment. But users still rely on software, wallets, exchanges, miners, and custody choices, so trust was reduced and redistributed, not erased. -
Why are stablecoins still centralized?
Most major stablecoins depend on private issuers and off-chain reserves such as Treasury bills, bank deposits, and money market instruments. That creates issuer risk, redemption risk, and dependence on custodians, auditors, and banking access. -
What is a sandwich attack?
It is a form of front-running where an attacker places trades before and after a victim’s pending transaction to capture profit. In public DeFi markets, that is one of the uglier ways “transparent” trading gets gamed. -
What are Ethereum block builders?
Builders are specialized actors who assemble transaction bundles into blocks. They matter because transaction ordering has become a specialized market, which can concentrate power even on a decentralized network. -
Why does tokenization create legal problems?
Because an on-chain token does not automatically guarantee off-chain ownership rights. If the blockchain record and the legal reality conflict, courts, trustees, and depositories decide what is enforceable. -
Why is South Korea relevant here?
South Korea is a useful case study because it is treating stablecoins and tokenized assets as serious financial infrastructure. That forces the real questions to the surface: who issues, who holds reserves, and who is liable when things go wrong? -
Can regulation kill the point of crypto?
Yes, if it turns everything into a permissioned clone of legacy finance. But no regulation at all leaves users exposed to issuer failure, abuse, and legal chaos. The challenge is setting rules without stripping away the benefits that made crypto interesting in the first place.
Crypto did not eliminate intermediaries. It reorganized them. Sometimes that is progress. Sometimes it is just the same old trust problem in cleaner software.
