Trace Mayer Promotes Upcoming Proof of Keys Event
Bitcoin advocate Trace Mayer tweets about January 3rd 'Proof of Keys' event, encouraging global participation in coordinated exchange withdrawal to promote self-custody.
On January 2, 2019, early Bitcoin investor and advocate Trace Mayer promoted the upcoming 'Proof of Keys' event scheduled for January 3rd—Bitcoin's tenth anniversary—through social media campaigns encouraging Bitcoin holders worldwide to withdraw their cryptocurrency from exchanges and take personal custody. The grassroots initiative aimed to test exchange solvency while promoting Bitcoin's self-sovereign ethos.
Mayer's Proof of Keys promotion emphasized that Bitcoin's revolutionary potential required users actually controlling their private keys rather than trusting exchanges with custody. The movement's slogan 'not your keys, not your Bitcoin' captured the fundamental principle that users leaving cryptocurrency on exchanges didn't truly own their Bitcoin—they held IOUs from exchanges that could be hacked, seized, or operated fractionally.
The January 3rd timing, coinciding with Bitcoin's Genesis Block anniversary, symbolically connected the withdrawal event to Satoshi Nakamoto's original vision of individuals controlling their own money without trusted intermediaries. Mayer argued that a coordinated global withdrawal would test whether exchanges actually held the customer Bitcoin they claimed, exposing any fractional reserve practices where exchanges claimed to custody more Bitcoin than they actually possessed.
The event also served educational purpose, teaching participants about self-custody practices including wallet setup, backup procedures, and key management—skills essential for true Bitcoin ownership but often neglected by users who found exchange custody more convenient. For Bitcoin's community, Proof of Keys represented philosophical commitment to decentralization and self-sovereignty rather than merely using Bitcoin as speculative investment vehicle on centralized platforms.
The movement's viral spread through social media demonstrated grassroots organizing capacity within Bitcoin communities and reflected growing concern about exchange custody risks following numerous hacks and failures throughout 2018.Mayer's promotional efforts helped establish what would become an annual Bitcoin tradition emphasizing the importance of self-custody and individual sovereignty.
