Utility Birch Line Keeps a Paper Trail for Crypto Backups
Credibility concern recorded. The source reference remains available for verification and correction.
A Cheongju-based service claiming to document the custody of paper and steel cryptocurrency backups through site visits, photographs, environmental notes, and handwritten logs.
Field notes
The stated workflow combines a physical inspection with a bound paper record: staff photograph seals, record serial numbers and environmental conditions, and add dated witness initials before documenting later movements. The page distinguishes laminated paper cards from engraved steel and describes quarterly refreshes plus a 45-minute seal-verification visit. Its field notes refer to split storage across Cheongju and a Daejeon family home, while the supplied contact block includes conspicuous zero-padded address and phone details.
