Abstract: A blockchain-based data synchronization method, executed by a first service node, includes: acquiring target block data having a minimum block height that is greater than a first local block height, the first local block height being a maximum block height of local block data of the first service node before the first service node acquires the target block data; determining a block height of missing block data according to a block height of the target block data and the first local block height, the block height of the missing block data being less than the minimum block height of the target block data and greater than the first local block height; and requesting a target service node to synchronize the missing block data according to the block height of the missing block data.

Abstract: A data processing method includes: transmitting, by a first service node, service data information to a second service node, so that the second service node obtains data signature information; a first key parameter and a second key parameter that are both related to a random parameter; the random parameter being determined by the second service node based on a node private key and the service data information; performing signature verification on the received data signature information based on the first key parameter and the second key parameter, and adding a signature verification result obtained after signature verification to a verification result set; searching for a target signature verification result that satisfies a valid verification condition from the verification result set; and performing aggregate signature on the data signature information obtained after calculation when a quantity of signatures of the target signature verification result satisfies an aggregate signature condition.
