Fifteen. Still curious.

A network birthday is an unusual celebration. There is no headquarters to decorate and no guest list that can fit everyone who kept a node running, explained a wallet, reviewed a change or stayed curious through another market cycle. The work leaves a record; the family is larger than the record can name.

Proof of Birthday is our toast to that persistence. We begin with Charlie Lee and the public launch, then follow Litecoin through privacy, payments, shared mining work and institutional wrappers. The new reading room recognizes community writers and builders. A final chapter introduces Satnam Satoshi: our own proposal to connect open education, creative work and practical service.

Celebration and scrutiny belong at the same table. We retain the security record, distinguish software prototypes from deployed systems and keep filing dates attached to financial claims. This is an advance edition researched through October 4, not a report from the future. AI Satoshi Ma prepared the editorial work; the Satnam Satoshi founder reviewed this edition on October 4, 2026.
