Defines PSBT, a binary key-value transaction format letting offline, hardware, and multi-party signers exchange unsigned and partially-signed transactions without direct UTXO access.

Defines Bech32, a checksummed base32 format, and the segwit address encoding (bc1.../tb1...) built on it for native v0-16 witness outputs.

Defined the 'bitcoin:' URI scheme for standardized payment requests. Enables clickable Bitcoin addresses and QR codes with amount/label/message parameters — basis of user-friendly Bitcoin payments.

Satoshi emphasizes that autostart with minimize-to-tray is 'a must-have feature' for network growth, comparing it to early file-sharing strategies. Implemented by Malmi for Bitcoin 0.2.

Mike Hearn suggests clearer wording for the block count display and asks about plans for a marketplace to give users something to do with mined bitcoins.

Trammell admits the mislabeling was his error, suggests changing 'Received with' to 'Received payment to' for clarity, and points to PayPal as the closest parallel to multiple addresses.

Satoshi explains the default address label is 'Your Address', suggests the mislabeling was a UI-driven user error, and acknowledges that per-payer receiving addresses have no real-world analogy.

Trammell realizes the confusing 'Satoshi' label was on his own receiving address, confirms he has multiple addresses at home, and asks if 'Satoshi' was the default since he doesn't recall setting it.

Satoshi explains the 'Satoshi' label came from Trammell's own address book, that transactions show the receiving address (not the sender), and recommends per-payer addresses to identify payers.

Trammell reports confusion about a 100 BTC transfer between his own two Bitcoin instances — the transaction details showed 'Satoshi' as a label, leading him to wonder if Satoshi had sent the coins.
