What is Computational Backlog?

Computational backlog (or debt) is defined as a set of calculations that must be completed to bring a backlog on a computer system, network, or related system up to date. Computational backlog occurs when a computer system or a blockchain network accumulates too much computational debt. This is a highly undesirable situation for a blockchain because it can result in deteriorating system performance, including significant transaction time delays. Computational backlog must be managed efficiently to maintain the long-term health of a network.
