Consensus is the security boundary. If it’s wrong, everything built on top is cosplay. We audit safety/liveness logic, incentive alignment, and implementation edge cases that become network attacks.
Consensus algorithm correctness assumptions
Validator incentives and slashing design
Finality gadgets and reorg handling
Network and timing assumptions
Implementation correctness and edge cases
Upgrade and parameter-change safety
what safety/liveness means here
adversarial network + rational actors
correctness at boundaries and edges
simulate or test high-risk cases
“what breaks the chain” narratives
Consensus-breaking bugs and incentive failures
Concrete scenarios and triggering conditions
Fix direction focused on invariant preservation
Retest confirmation
Frequently Asked Questions
We verify that your blockchain's consensus mechanism is secure against attacks: Can validators collude? Can the network be halted? Can blocks be reorganized? Can economic incentives be gamed? Consensus is the root of all chain security.
If consensus fails, everything built on top fails. Contracts, tokens, user funds—all depend on the chain producing valid, final blocks. Weak consensus = game over.
We model scenarios where validators go offline, network partitions occur, or adversarial nodes refuse to propose blocks. The network must continue producing blocks or gracefully degrade without losing safety.
We verify that honest behavior is always more profitable than attacking. If validators can earn more by censoring transactions, colluding, or manipulating consensus, the economic model is broken.
We model the cost to acquire 51% stake or hashpower, the time required, and the expected profit. If attacking is cheap or profitable, we flag it. Economic security must exceed potential attacker capital.
Slashing that's too harsh can centralize validation (only well-funded validators survive). Slashing that's too weak doesn't deter attacks. Governance parameters can create deadlock or allow minority control. We test these edge cases.
It proves your chain won't break under adversarial conditions. Investors, validators, and users need confidence that consensus actually works when tested.
