Public Blockchain: How Open Ledgers Power Crypto, Airdrops, and Decentralized Apps

When you hear public blockchain, a transparent, permissionless digital ledger where anyone can verify transactions and participate in validation. Also known as open blockchain, it’s the backbone of Bitcoin, Ethereum, and every crypto airdrop you’ve ever heard of. Unlike private systems controlled by companies, a public blockchain lets anyone see every transaction ever made — no secrets, no hidden owners. That’s why it’s the only kind that can truly support things like NFTs, DeFi apps, and token airdrops without needing a middleman.

Think of it like a global, always-open spreadsheet that runs on thousands of computers. Every time someone sends ETH, claims a GEAR token, or trades SMOG on a DEX, that action gets recorded permanently. This openness is what makes projects like APENFT’s massive NFT airdrop possible — anyone with a wallet can prove they qualified. But it also means privacy coins like Monero, which hide transaction details, exist in a gray zone. Public blockchains don’t allow anonymity by design, which is why regulators keep pushing for transparency and why exchanges delist privacy-focused coins. Meanwhile, wrapped tokens like WBTC and stablecoins like USDC rely on public blockchains to move across networks, proving that interoperability only works when the ledger is open for everyone to audit.

What you’ll find in this collection aren’t just theory pieces — they’re real-world stories of what happens when public blockchains meet ambition, scams, and regulation. From the silent death of OpenDAO’s SOS token to the rise of BLOK in the Bloktopia metaverse, every post shows how openness creates opportunity — and vulnerability. You’ll see how sharding improves speed on Ethereum, how Iran uses Bitcoin mining to bypass sanctions, and why fake airdrops like BSC AMP and TRO keep popping up. Public blockchains don’t care if you’re a trader, a gamer, or a skeptic — they just record what happens. And that’s exactly why you need to understand them before you invest, claim a token, or even click on a "free crypto" link.
