Atoms, Institutions, Blockchains

" summary

Key claims: defines hardness as the shared property — from atoms (gold), institutions (courts, police), or blockchains — that makes specific future states predictable; coins a cast as any future state hardened this way (loan enforcement, gold supply, key-controlled transfers). Compares strengths and limits: atomic immutability vs institutional programmability vs blockchain transparency, low startup cost and global access, notes measurability (probability or cost to break a cast) and argues blockchain hardness is a distinct, non‑institutional source enabling new coordination and experiments.
