Practical research on protecting private keys, planning recovery and testing the physical durability of seed backups.
Why read Jameson Lopp?
Lopp's seed-backup guide starts with the failures a recovery plan must survive: destruction, theft and a backup that its owner cannot successfully restore. He explains the tradeoffs between redundancy, complexity and access, then insists on testing recovery. It is a useful framework for understanding why buying a backup device is only one part of protecting a wallet.
His metal-storage tests let you inspect what happens to actual backup products under heat, corrosion and crushing. The review index brings those results together for comparison. Read the guide first to define the problem you are solving, then the tests to examine whether a particular physical design survives the relevant kind of damage.
