Consensus Overhead
Consensus Overhead is the computational and communication burden placed on a network to achieve agreement among distributed nodes regarding the state of the ledger. This overhead includes the messages exchanged between validators, the verification of signatures, and the processing time required to reach a majority agreement.
In the context of derivatives, this overhead directly impacts the speed at which margin requirements can be updated and positions can be adjusted. If the overhead is too high, the network becomes sluggish, reducing the frequency at which order books can be updated or liquidation thresholds can be checked.
Balancing security with low consensus overhead is a primary challenge in blockchain design, as more robust security measures often require more complex and time-consuming consensus protocols. Reducing this overhead is essential for scaling decentralized finance to match the speed of traditional financial markets.
