Probabilistic Settlement Risks

Probabilistic Settlement Risks refer to the possibility that a transaction could be reversed or invalidated after it has been initially processed, a common characteristic of proof-of-work blockchains. Because these networks rely on the accumulation of work to secure the ledger, a transaction is only considered final with a high degree of confidence after several blocks have been mined on top of it.

For institutions, this creates a risk management challenge: they must decide how many confirmations to wait for before treating the asset as settled. If an institution acts too quickly, it risks accepting a transaction that could be orphaned in a chain reorganization.

If it waits too long, it suffers from capital inefficiency. Managing this risk requires sophisticated monitoring of network health and hashing power.

It is a fundamental consideration in the design of custody systems that interact with legacy blockchain protocols.
