Consensus Failure Probability

Consequence

Consensus Failure Probability represents the quantified risk associated with a blockchain network’s inability to reach agreement on the validity of transactions or the state of the ledger. This probability is fundamentally linked to the network’s security parameters, including the hashing power distribution and the chosen consensus mechanism, directly impacting the reliability of smart contract execution and asset custody. Assessing this probability necessitates modeling potential attack vectors, such as 51% attacks or Sybil attacks, and their associated costs relative to the potential gains for malicious actors, influencing the overall economic security of the system. Consequently, a higher probability signals increased vulnerability and potential for disruption, demanding robust mitigation strategies.
