BIP 32 introduced hierarchical deterministic wallet trees
BIP 32 describes deriving many public and private keys from a master seed through a structured hierarchy.
That structure made wallet backup and account organization more practical than managing unrelated keys, while enabling watch-only wallet setups.
The standard became foundational to modern wallet interoperability and informed later path conventions used by wallet software.
A seed still represents powerful access: portability improves recovery, but secure storage and careful handling remain essential.
