Minimal, elegant protocol design that preserves optionality and prevents over-specification, following the concept of pu.
Pu, the 'uncarved block' or 'raw wood,' represents undifferentiated potential—the state before unnecessary complexity. Laozi warns against over-specification: once you carve the block, you've limited its possibilities. The best blockchain protocols maintain this principle: Bitcoin's elegant simplicity allows it to remain Bitcoin across decades, while overly-specified systems require constant upgrades. Minimal viable protocols preserve the possibility space; they don't prescribe every use case. Layer-two protocols, privacy solutions, and application-layer innovations can flourish in space created by simple base layers. Conversely, protocols that attempt to optimize for every foreseeable use case become rigid, hard to upgrade, and fragile. Laozi's wisdom here is profound: the most powerful protocol is one that achieves its core function beautifully, then gets out of the way, allowing organic development above it.
