In computing and networking, a Single Point of Failure (SPOF) refers to a component whose failure will stop the entire system from functioning. This can include hardware, software, or even a specific process. In the context of web3 and decentralized networks, the concept is particularly relevant, as decentralization aims to reduce or eliminate SPOFs by distributing control and redundancy across the network. Design strategies that avoid SPOFs are crucial for creating resilient systems.
