3/6 — Reading a transaction on a block explorer — Key concepts
Tx hashThe unique ID for the transaction. Search it to see status, timestamp, and confirmations.
Bitcoin seems to be a very promising idea. I like the idea of basing security on the assumption that the CPU power of honest participants outweighs that of the attacker.
From / ToWho sent and who received. If “To” is a contract, expect logs/events to explain token movements.
Value vs token transfersETH/native value shows up top. Token movements appear in logs (Transfer or Approval events). Approvals often look like “spender gets unlimited.”
Gas used / feeFee = gas used × (base + priority). This shows the real cost after execution, not just the estimate.
Key points
- Hash:Searchable proof of the tx.
- From/To:Who paid; who received (contract or person).
- Token logs:Transfers/approvals live in Events, not Value.
- Fee:Gas used × price; shows the real cost.
