Namdong-gu reading room
On-chain transactions, on paper
Think Compass keeps a Solana learning library and a single oak table. You sit with a reader, and a confirmed transaction is taken apart in the order the chain stored it.
The signature walkthrough follows the message. Nothing is renamed into a slide. The pencil moves in the same sequence every time, so a second visit feels familiar.
Who signed, and which account sits first as the fee payer.
Writable and read-only flags, counted from the header before any story about the transfer.
Program, account indexes, and the data described in words. Lookup tables get their own sheet.
Fee in lamports, balance changes, compute units, and the log lines if the slot already closed.
The library is the shelf. The commercial work is a booked seat: a walkthrough, a paper map of the accounts, or a quiet hour with one guide.

Every account in one transaction becomes a block on kraft paper, with owner and lamports written beside it.

One guide, one window desk, and ten minutes of questions at the end of the hour.
Read the sittingHana stayed on the writable flag until I could say it back without looking at her. The printout type is small, and I had to pull the page closer under the window. After that the failed instruction was obvious: the account I kept calling the sender was only being read.
Most people arrive with a signature already confirmed on mainnet-beta: a token transfer, a program call that returned an error, or a sample from our folder when they want the method before they risk their own. The hour stays on that one message.
Notes from other sittings, including one map that stopped at the accountant’s door, are collected on the visitor page.
Four clothbound guides cover the fields we are asked about most. They can be read in the room during a library hour, and the same essays are here.
Sessions are seated. The desk confirms a time by email after you write, then sends transfer details for the deposit. The website lists rates so you can decide whether the hour fits; it does not take payment itself.
Tuesday to Saturday, 10:00 to 18:00. Monday is for reprinting guides and is closed to visitors.
