📚 What You've Learned
Understanding what blockchain explorers are, why they're essential, and the three main views: blocks, transactions, and addresses
Reading block data including height, timestamp, miner/validator, transaction count, and understanding block confirmation
Decoding transaction details, tracking status from pending to confirmed, understanding gas fees and transaction types
Looking up addresses to see balances, transaction history, token holdings, and activity patterns
🔑 Critical Concepts
Everything on blockchain is public and permanent. Explorers make this data human-readable and searchable.
Every transaction gets a unique TXID. Save it to track status, prove payment, or debug issues.
1 confirmation = in a block. 6+ confirmations = very secure. More confirmations = harder to reverse.
Full transaction history reveals patterns, relationships, and behavior. Privacy requires careful address management.
Anyone can use explorers without permission. No account, no KYC - just search and explore freely.
