Blockchain Determinism Limitations

Constraint

Blockchain determinism limitations arise from the requirement that all nodes in a decentralized network must arrive at the exact same state transition from the same initial conditions. This constraint creates a challenge for smart contracts that need external, real-world data, such as market prices or interest rates, which are inherently non-deterministic and constantly changing. The inability to directly access off-chain information without compromising consensus integrity forces protocols to rely on external data feeds.
