1. A blockchain generation method implemented by a client, comprising:
sending first transaction information to a first node device, wherein the first transaction information comprises first basic information and first digest information about a first transaction, the first transaction information instructs the first node device to perform a first simulating transaction that simulates the first transaction, and the first basic information comprises transaction data and a transaction object of the first transaction;
receiving a first endorsement result sent by the first node device, wherein the first endorsement result comprises a signature generated after the first simulating transaction succeeds;
determining whether the first endorsement result meets a transaction condition; and
in response to the determination that the first endorsement result meets the transaction condition, sending the first digest information and the first endorsement result to a second node device, so that the second node device sends to the first node device, based on the first endorsement result, the first digest information used to generate a blockchain.
