Abstract
Embodiments of the present specification provide example blockchain-based data processing methods, mediums, and systems. One example method includes obtaining an available Nonce record for a target transaction from a Nonce list. The Nonce list comprises Nonce records, and each Nonce record comprises a version identifier of the Nonce list and a Nonce value. The available Nonce record to the target transaction is added. The target transaction in a blockchain is published. Prompt information indicating that the target transaction is an invalid transaction is received when a version identifier in the available Nonce record does not match the version identifier of the Nonce list; or a notification message indicating that the target transaction is processed is received when the version identifier in the available Nonce record matches the version identifier of the Nonce list and a replay attack detection is successfully performed by matching the available Nonce record with a Nonce record in the Nonce list.
