HD wallets, seeds and derivation
BIP 32 (2012) made one seed stand for every key a wallet will ever use; BIP 39 turned the seed into words, and BIPs 43, 44, 49, 84 and 86 agreed where each kind of address lives. The threads include the arguments the standards left out, such as whether BIP 39 was a good idea.
