## Consensus Mechanism Exploits

Consensus mechanism exploits refer to technical vulnerabilities or strategic attacks targeting the protocols that allow distributed networks to agree on the state of a ledger. In blockchain systems, these mechanisms like Proof of Work or Proof of Stake ensure transaction validity without a central authority.

An exploit occurs when an adversary manipulates the rules of this consensus process to double-spend assets, censor transactions, or reorganize the chain history. These attacks often leverage weaknesses in the network propagation, validator incentive structures, or low-cost hash power acquisition.

By compromising the agreement process, attackers can effectively invalidate the finality of financial settlements within the protocol. This poses a severe threat to the integrity of decentralized finance applications that rely on these chains for underlying collateral valuation.
