Pu—the uncarved block—represents elegant protocol design with minimal unnecessary features, maximizing resilience through elegant constraint.
Pu, the uncarved block, symbolizes Taoist simplicity: an object before modification, containing infinite potential. Bitcoin embodies this principle—a deliberately minimal protocol that does one thing supremely well: create immutable, decentralized transaction ledgers. Every feature Satoshi didn't add strengthened the network. Complex blockchains that attempt to do everything—smart contracts, tokens, governance—introduce surface area for attack and fragmentation of purpose. Laozi teaches that carved wood loses its natural resilience; over-specification kills elegance. The most antifragile protocols share Pu's quality: strict in core function, flexible in application. Ethereum's flexibility serves different purposes but sacrifices Bitcoin's crystalline simplicity. Neither is wrong—but Taoist wisdom suggests that protocols should maintain maximum simplicity in their essential nature, allowing complexity to emerge at application layers rather than being baked into core architecture. Humility about what a protocol should do is wisdom.
