Codex32
Also covering BIP93
Codex32 is an encoding designed for BIP32 seeds that is convenient to store on paper. It supports relatively simple processes for creating a seed, encoding that seed, splitting the seed into parts (requiring a configurable quorum of parts to gain any knowledge of the seed), and verifying the integrity of partial or full seed backups. The processes, though simple, can be laborious, but optional paper assistive devices (volvelles) can reduce some of the effort.
