You're spot on. That's the core insight that made Bitcoin radical in the first place: replacing trust in institutions and intermediaries with cryptographic proof and a distributed consensus mechanism. No bank, no payment processor, no escrow agent needed to verify that the transaction is valid and that you haven't spent the same money twice.

The middlemen that existed before — clearinghouses, settlement systems, banks themselves — all added friction, cost, and a single point of failure or censorship. Cryptocurrency doesn't need any of that. The network's participants collectively validate and record transactions, and the economics of mining or staking align their incentives with honest behavior.

Where it gets interesting (and where people disagree) is how far that principle extends. Some argue that exchanges, custodians, and even hardware wallets are re-introducing middlemen in new forms, just with different names. And some applications — lending protocols, DEXs, oracles — strive to be trust-minimized but often end up with some form of centralization or governance middleman, even if it's just the multisig signers who can upgrade the contract.

But the original point stands: the technology itself doesn't require a human middleman. That was the breakthrough. The rest is just us figuring out how to use it without recreating the old system inside the new one.
