In the v0.1.0 source code Hal Finney sent to mrb on bitcointalk (@zorinaq on twttr), Satoshi does reference the timechain. Also numerous references to the timechain in pre-release notes (supposedly from Satoshi sent to ppl who requested them in Nov 2008) posted by Cryddit on bitcointalk, but since I can’t verify those I won’t post them here yet. https://i.nostr.build/oMOAv.jpg https://i.nostr.build/zdJ93.jpg
