Blockchain Explained: How It Powers Crypto, DeFi, and Digital Ownership

When you hear blockchain, a distributed digital ledger that records transactions across many computers so that any involved record cannot be altered retroactively. Also known as distributed ledger technology, it’s the reason you can send Bitcoin without a bank, trade tokens on a decentralized exchange, or prove you own a digital artwork. This isn’t science fiction—it’s the foundation behind every crypto project you’ve heard of, from Bitcoin to Solana to the weird meme coins no one talks about anymore.

Blockchains don’t just store money. They store rules. That’s where smart contracts, self-executing code on a blockchain that automatically enforces agreements when conditions are met come in. They’re what let you stake BNB on Lista DAO, trade synthetic stocks on Kwenta, or get paid one cent at a time for reading an article. No middleman. No paperwork. Just code doing what it’s told. But here’s the catch: most projects don’t build on smart contracts well. They promise DeFi rewards, but forget to lock in real liquidity. Or they claim to verify digital ownership, the unchangeable record of who created and owns a digital asset, proven through blockchain timestamps and cryptographic signatures—but if the NFT has no trading volume and the team vanished, that proof means nothing.

That’s why the posts below aren’t just reviews. They’re autopsy reports. You’ll see how MoveApp’s move-to-earn app vanished, why SkullSwap has zero users, and how SHREW never had an airdrop at all. You’ll learn how blockchain finality affects your trades on Solana versus Ethereum, how Wrapped Bitcoin bridges two worlds, and why a $36.77 daily volume on Dark Knight Swap isn’t a feature—it’s a warning. Some of these projects tried to use blockchain to fix problems. Most just used it as a label to sell tokens. The real value isn’t in the tech—it’s in the execution. And that’s what separates the ones that last from the ones that disappear.

Below, you’ll find real breakdowns of exchanges, tokens, and protocols—all built on or around blockchain. No fluff. No hype. Just what works, what doesn’t, and why.
