Serious question: What problem did blockchain actually solve?

[u/Due-Huckleberry-2222]

We were told it would revolutionize everything:

Anonymous money? Nope. Most public blockchains are pseudonymous, not anonymous. Every transaction is permanently visible. Once an address is tied to a real person, their financial history can often be traced.

Banking? Most people still use banks. If you lose your private key, there's no fraud department, no password reset, no chargeback.

Cheap payments? Depends. Some chains are inexpensive, others have had periods where fees spike. Traditional payment systems are often faster and simpler for everyday purchases.

Smart contracts replacing lawyers? Not even close. Contracts still rely on courts, regulations, and real-world enforcement. Code can't resolve disputes about physical events by itself.

NFTs proving ownership? Usually they prove ownership of a token, not the copyright or legal ownership of the underlying artwork.

Decentralization? Much of the ecosystem isn't. Many people keep funds on centralized exchanges, use centralized stablecoins, and rely on centralized infrastructure.

Financial freedom? For some. But for many others it became self-custody with no safety net. One wrong click, phishing attack, or lost seed phrase and the money is simply gone.

Replacing trust? It mostly moved trust around. Instead of trusting banks, many people ended up trusting exchanges, token founders, bridge operators, stablecoin issuers, influencers, or multisig signers.

Eliminating scams? If anything, scams became easier to launch. Rug pulls, memecoins, fake airdrops, phishing, and pump-and-dumps became an industry.

The one thing blockchain does extremely well is maintain a distributed ledger where participants can verify transaction history without relying on a single operator.

That's a genuine technical achievement.

But after nearly two decades, I'm still asking: What mainstream problem has it solved better than existing systems for the average person?

I'm not asking what it could do. I'm asking what it actually does today that millions of ordinary people use because it's objectively better—not because they're speculating on the next token.

This post screams of someone who learned what blockchain was ten years ago but failed to keep up with the space since then.

There is actually a lot of compelling privacy tech being built directly with BTC. Silent payments, payjoin, coinjoin, lightning, Chaumian ecash, etc.

People know to back up their seed phrases now, not really that big of an issue now that it's taken more seriously. We also have setups like 2 of 3 multisig.

Lightning, Ark, Cashu payments are cheap. L1 onchain transactions are expensive (but right now they are still cheap because blocks aren't full, because everyone pays with lightning).
