A ‘paper computer’ for Bitcoin checksums and Shamir Secret
Sharing may seem absurd, but that’s what we’re talking about in
this episode! This project is a scheme to generate, encode,
checksum, split and recover Bitcoin secret keys, using pencil,
paper and lookup tables (alternately, volvelles). We discuss
codex32 and the motivation behind it with Andrew Poelstra
(Director of Research, Blockstream). Note this is the first of a
two part episode. In this first part we discuss:

Bitcoin private keys today

Multi signature and Shamir Secret Sharing contrasted

Where to keep shards or keys

Error correction

Risks with Hardware wallets (even though you should still use
them)

BIP39 vs codex32

Limitations of the paper computer (Volvelles)
