## Consensus Fault Tolerance

Consensus fault tolerance measures a network's ability to continue operating correctly even when some of its components fail or act maliciously. This is a classic problem in distributed systems, often addressed through Byzantine Fault Tolerance mechanisms.

In the context of blockchains, the network must reach a common state despite the presence of nodes that may be offline, slow, or actively trying to deceive the system. The degree of fault tolerance determines how many nodes can be compromised before the entire network collapses.

This is directly related to the number of validators and the distribution of their stake. A higher fault tolerance makes the network more resilient to censorship and systemic attacks.

It is a fundamental design goal for any decentralized system, ensuring that the financial infrastructure remains operational regardless of individual participant failure. By modeling these scenarios, engineers can build protocols that withstand various adversarial conditions.

This concept is vital for the long-term viability of decentralized finance and digital asset settlement.
