Bitcoin (BTC) was built on a radical promise: money that works without trusted intermediaries. Yet 17 years after the first block challenged the post-crisis banking order, a growing body of research and market evidence suggests the crypto economy is rebuilding the very gatekeepers it set out to remove—only now under more technical labels such as stablecoin issuers, custodians, auditors, or DeFi ‘block builders’.
That is the central argument highlighted in a recent report from the Centre for Economic Policy Research (CEPR), which assesses blockchain’s original ambition against how today’s on-chain finance actually functions. The verdict, in the report’s framing, is a paradox: decentralization succeeded at maintaining shared ledgers without a central authority, but modern crypto markets increasingly reintroduce centralized points of control where trust—and risk—concentrates.
The early achievement remains hard to dispute. Bitcoin proved that a global network of participants who do not know or trust one another can still agree on a single history of transactions, adding blocks roughly every 10 minutes and preventing double spending without relying on banks or governments. Ethereum (ETH) expanded the model by popularizing smart contracts—code that automatically executes agreements—turning the decentralization of money into a broader decentralization of ‘contract execution’.
But as blockchain systems scaled beyond experimentation into payments, trading, credit, and tokenized assets, the market began filling what traditional finance would call “institutional gaps.” The result is not necessarily a failure of the technology; it is a reminder that finance runs on layered trust. The question is where that trust is anchored—and whether users understand the new dependencies that come with it.
Stablecoins: the return of issuer risk
No segment illustrates the shift more clearly than stablecoins. They are often marketed as a bridge between blockchain settlement speed and the price stability of fiat currencies such as the U.S. dollar. In practice, however, most leading stablecoins are not “purely” decentralized instruments. They are issued by private entities, backed by off-chain reserve assets such as Treasury bills, bank deposits, and money market instruments, and supported by relationships with custodians, banking partners, and auditors.
