Peter Todd's first BitcoinTalk post: buying a Diaspora invite

Peter Todd's very first post on BitcoinTalk, made one minute after registering under the username 'retep.' A single sentence offering to buy a Diaspora social network invite for $2 — notably in USD, not BTC, unlike other buyers in the thread who offered 0.5–2 BTC. Three days later, his second post would be a technical reply to Satoshi Nakamoto's description of transaction replacement.

Peter Todd and David Harding formalize Replace-by-Fee in BIP 125

BIP 125 formalized opt-in Replace-by-Fee (RBF), allowing Bitcoin transaction senders to signal that their unconfirmed transactions may be replaced by higher-fee versions. The concept traces directly to Satoshi Nakamoto's original transaction replacement mechanism described on BitcoinTalk in December 2010 — the same thread where Peter Todd made his second-ever forum post.
