## Orphan Block Risk

Orphan block risk arises when two miners or validators produce valid blocks simultaneously, causing a temporary fork in the blockchain. The network eventually selects one chain, and the block that is not included is considered an orphan or stale block.

This risk is higher when network propagation is slow, as nodes may not be aware of the latest block when they begin mining the next one. For financial systems, this creates uncertainty, as transactions included in an orphan block are effectively reversed.

Managing this risk requires balancing network decentralization with efficient block propagation. It is a fundamental trade-off in the physics of blockchain consensus.

Participants must wait for sufficient depth to minimize exposure to this risk.
