Peter Todd

He wrote E4M, then built a criminal empire. The evidence behind The Mastermind (2019) naming Paul Le Roux as Satoshi, weighed.

Attorney James A. Murphy filed a 2025 FOIA suit seeking DHS files on Agent Rana Saoud's 2019 claim that investigators interviewed four people believed to be behind Bitcoin.

Finding Satoshi (Tooley / Miele, April 2026) names Hal Finney and Len Sassaman as Bitcoin co-creators — Finney coded, Sassaman wrote the paper. Lopp and Back disputed the timing.

How the Bitcoin ecosystem layers above and around the base chain: Lightning payment channels, federated sidechains, L1 envelope extensions, and mining pool architectures.

On the public record, Satoshi developed Bitcoin on Windows exclusively for 27 months (design + release + early period); Linux engagement first appears as reactive support for Malmi's port.

Editorial reading of how the 2014 'Bitcoin Core' rebrand reshaped Bitcoin's authority vocabulary — PR #3408 internal disagreement, the 2015-2017 fork episodes, and Hearn's 2025 retrospective regret.

b-money is whitepaper reference [1], his Crypto++ shipped inside Bitcoin v0.1, and he was the second person Satoshi contacted. The evidence for Wei Dai as Satoshi, weighed.

Bitcoin Institute reanalysis of van Dorst's stylometric corpus for the five most-cited candidates. Finding: Szabo top at 4.67th percentile of 12,739 authors; 594 unnamed rank closer; corpus is noisy.

On February 22, 2021, Evan Hatch published Len Sassaman and Satoshi: a Cypherpunk history on Medium — the most-cited public articulation of the Sassaman = Satoshi Nakamoto hypothesis.

On April 8, 2026, the New York Times published John Carreyrou's investigation naming Adam Back as the most likely Satoshi based on stylometric analysis. Back denied the identification.

Reads the asymmetry between public attempts to identify Satoshi, the surviving material trail, and the persistent identification gap.

Structural reading of how "Satoshi Nakamoto" remained unidentified across development, public phase, and withdrawal. Six layers: pseudonym, channels, language, env, genesis constants, handover.

A reply that read like the continuation of Satoshi's thought — and two days later, Satoshi went silent. The evidence for HBO's Peter Todd identification, weighed.

Recurring Satoshi candidates aligned across four independent layers — profile match, stylometric attribution, direct correspondence, and development environment.

Peter Todd's first BitcoinTalk post, 41 seconds after registering as retep — offering $2 USD (not BTC, unlike others) for a Diaspora invite. His second post was a technical reply to Satoshi.

Peter Todd proposed BIP 65, introducing OP_CHECKLOCKTIMEVERIFY — an opcode locking transaction outputs until a future time. Deployed as a soft fork, enabling escrow and payment channels.

BIP 125 formalized opt-in Replace-by-Fee (RBF), tracing directly to Satoshi's December 2010 BitcoinTalk replacement mechanism — the thread where Peter Todd made his second-ever forum post.

Peter Todd announced OpenTimestamps, an open-source infrastructure using the Bitcoin blockchain to timestamp unlimited documents per transaction via Merkle tree aggregation.

Peter Todd participated in the Zcash trusted setup ceremony in October 2016 — driving across BC, shielding his laptop in a Faraday cage, and torching the hardware — then criticized the process.

HBO documentary Money Electric (Cullen Hoback) named Peter Todd as a Satoshi candidate, citing a 2010 BitcoinTalk reply about RBF and Todd's later BIP 125. Todd called the claim ludicrous.
