Crypto Library Archives: June 2025 Blockchain and Airdrop Updates

When you look at blockchain, a decentralized 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 backbone of every crypto project you care about. In June 2025, the focus wasn’t on hype—it was on what actually worked. Real users needed to know which wallets stayed secure, which airdrops paid out, and which exchanges finally fixed their withdrawal delays. This archive pulls together everything that mattered during that month, stripped of noise and filler.

cryptocurrency, a digital or virtual currency secured by cryptography, often operating independently of a central bank. Also known as crypto tokens, it’s what drives the whole system. June saw a few major coins gain traction not because of celebrity tweets, but because their networks improved speed and cut fees. Ethereum’s Layer-2 solutions became more reliable for everyday swaps. Solana kept its momentum with fewer outages than ever. And a quiet upstart, $ZK, proved its privacy tech could handle real-world volume without crashing. These weren’t guesses—they were tested results.

airdrop alerts, notifications about free token distributions from blockchain projects to reward early adopters or community members. Also known as token giveaways, they’re one of the few ways regular people get exposure to new projects without spending money. That month, over 12 verified airdrops went live. Some required simple tasks like joining a Discord or holding a specific NFT. Others demanded active participation in governance votes. We tracked which ones actually delivered tokens, which ones disappeared after claiming, and which wallets got flagged by scams. No guesswork. Just facts.

wallet security, the practices and tools used to protect digital assets from theft, loss, or unauthorized access. Also known as crypto custody, it’s the difference between keeping your coins safe and losing them forever. In June, phishing attacks targeting MetaMask users spiked. We published simple checks anyone can do: Did you verify the URL before signing? Did you use a hardware wallet for anything over $500? Was your recovery phrase stored in a physical vault, not a screenshot? These aren’t advanced tips—they’re basic habits that still save people thousands.

exchange comparisons, evaluations of cryptocurrency trading platforms based on fees, security, liquidity, and user experience. Also known as crypto exchange reviews, they help you pick the right place to buy, sell, or hold. Two big exchanges changed their fee structures. One slashed withdrawal fees for stablecoins. Another removed its free deposit option for altcoins. We broke down what each change meant for your wallet. If you traded often, one platform became cheaper. If you held long-term, another became safer. No bias. Just numbers.

What you’ll find here isn’t a list of headlines. It’s a record of what happened when real people used these tools. No theories. No predictions. Just what worked, what broke, and what you should watch out for next time. These posts were written for someone who just wants to know: Can I trust this? And the answers are right here.
