Blockchain Consensus Risk

Consensus

Blockchain consensus risk describes the potential for a failure or compromise of the underlying network’s validation mechanism, which directly impacts the integrity of financial instruments built upon it. A successful 51% attack or a critical protocol bug can lead to a chain reorganization, effectively reversing transactions and invalidating the state of the ledger. This fundamental vulnerability introduces significant uncertainty for derivatives protocols that rely on the immutability of on-chain data for collateral valuation and settlement. The risk is particularly acute in proof-of-work systems where a concentration of mining power can be exploited to manipulate transaction order and finality.
