A concrete example
An Ethereum transaction with nonce 8 normally follows nonce 7; this is not a mining puzzle.
In context
An account nonce orders outgoing transactions and prevents replay within the relevant transaction sequence. A transaction also specifies fee parameters, a destination where applicable, value and data. Contract-call data encodes a function and its arguments. A missing earlier nonce can delay later transactions.
