According to the blockchain consensus algorithm, the verification cost of each layer of nodes is fixed. For example, in the SHA-256 algorithm of Bitcoin, each node needs to consume 200,000 times the verification cost of a single transaction.\n\nNote: The translation may vary depending on the context and specific usage of the terms.
