Embodiment Construction

[0047] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", and "bottom" used in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the The invention and the simplified description do not indicate or imply that the device or element referred to must have a specific orientation...

Abstract

The embodiment of the invention relates to a block data transmission method and device, electronic equipment and a nonvolatile computer storage medium. The block data transmission method comprises thefollowing steps: constructing a Bloom filter; sending the block information of the Bloom filter and the new block; generating estimated data of the transaction difference between the sending node andthe receiving node; generating a first reversible Bloom lookup table corresponding to the new block according to the estimation data; determining a public transaction between the sending node and thereceiving node through the Bloom filter, and constructing a second reversible Bloom lookup table corresponding to the public transaction; and performing subtraction operation on the first reversibleBloom lookup table and the second reversible Bloom lookup table, solving a specific transaction of the sending node, and reconstructing a block according to the specific transaction. According to theblock data transmission method, estimation data of transaction difference between a sending node and a receiving node is given in advance, so that the size of a reversible Bloom lookup table can be reasonably selected, and the probability of inverse solution failure can be controlled.

Description

【Technical field】 [0001] The present invention relates to the technical field of block chain, in particular to a block data transmission method, device, electronic equipment and non-volatile computer storage medium. 【Background technique】 [0002] There is no centralized node in the blockchain system, all nodes are equal, and all data and status need to be synchronized to all nodes in the system eventually. [0003] In the public chain, since the system is permissionless, the number of system nodes is not limited. When the number of system nodes is very large, the amount of data that the entire system needs to transmit due to state synchronization will be very large, which greatly limits the scalability of the blockchain system. [0004] In the current blockchain system, the data and status information that nodes need to synchronize are obtained through block transmission. A block is a collection of multiple transactions, and the system synchronizes the block to synchroniz...
