Back to: Blockchain Basics
Blockchains are public, which means “do your own research” is a skill, not a slogan. This lesson makes you dangerous with a block explorer in fifteen minutes.
The four lookups
1. Transaction hash → status (confirmed/pending/failed), from/to, value, fee, network. “Did it arrive?” ends here. 2. Address → balance + full history. Whale-watch, treasury-audit, or check your own wallet without opening it. 3. Block → who built it, how full, what fees prevailed. Congestion reads here first. 4. Token contract → holders list, supply, verified code? Unverified code + concentrated holders = walk away.
Verifying claims (the fun part)
– “Huge community treasury!” → open the treasury address. Count it yourself. – “Burned liquidity!” → check the LP tokens: locked, burned, or sitting in a dev wallet? – “Partnership with X!” → find the on-chain transaction or it didn’t happen. – “Vitalik holds our token!” → check whether he can *sell* it (or if it’s a honeypot transfer he never touched).
Metrics that matter vs theater
– Matter: Nakamoto Coefficient, client diversity, unlock schedules, holder concentration, real fee revenue. – Theater: raw TPS claims, follower counts, “partnerships,” exchange listing rumors, celebrity holdings.
The explorer is the difference between believing a website and checking
> reality. Professionals check; amateurs trust. The data is free — use it.
