Satoshi Nakamoto describes a possible design for transaction replacement — allowing a double-spend with a higher fee to replace the original transaction. This concept would later become known as Replace-by-Fee (RBF). Peter Todd replied to this post approximately 1.5 hours later.
Defined a signaling mechanism for opt-in Replace-by-Fee (RBF), allowing unconfirmed transactions to be replaced by new versions with higher fees. RBF improved fee estimation and market efficiency but was controversial for its impact on zero-confirmation transaction security.
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.
HBO documentary 'Money Electric: The Bitcoin Mystery,' directed by Cullen Hoback, names Peter Todd as a Satoshi Nakamoto candidate. The film's central evidence was a 2010 BitcoinTalk forum post where Todd replied to Satoshi's description of Replace-by-Fee, and Todd's later formalization of RBF in BIP 125. Todd denied the claim, calling it 'ludicrous.' The documentary was widely criticized by the Bitcoin community.
