Desk notes
Field notes from sittings and Thursday circles.
These are the pages the desk wishes a visitor had read before bringing a signature. They stay on public explorer fields: fees, owners, logs, slots.
Slots, blocks, and why two explorers disagree for a minute
A slot is not always a block. Two explorers can show different commitment for the same signature until the cluster has finished its confirmations.
A failed transaction can still show the inner program
A red failure line does not mean the page is empty. The fee was still paid, and the logs usually name the program that returned the error.
Owner, lamports, and the executable flag
An account page is a small record with a large vocabulary. Owner, lamports, and the executable flag tell you what kind of thing you opened before any parsed balance does.
The fee payer line on a Solana transaction page
The largest token move on the page is often someone else's. The fee payer is a smaller line, and it is the one that tells you who paid the network.
