Abstract

The invention relates to an ASIC array for block excavation. The ASIC array comprises a plurality of ASIC chips disposed on a PCB. Each of the ASIC chips includes a plurality of bare dies; the bare dies include on-chip networks including a plurality of computing nodes; and each computing node includes a mixing operation device that is used for carrying out parallel address operation on a random number in a random data set of block excavation. According to the ASIC array, the mixing operation device is arranged at each computing node; on the basis of a computing node-on-chip network-ASIC chip-ASIC array layered structure, the ASIC array has a plurality of mixing operation devices capable of processing the random numbers in the random data sets in parallel; and the mixing operation devices are used for carrying out multi-task parallel processing, so that the hash calculation efficiency of block excavation is improved effectively.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and equipment for block mining, and an ASIC array and a data processing board adopting the block mining method. Background technique [0002] Ethereum (Ethereum) is a brand new blockchain platform that allows anyone to build and use decentralized applications that run on blockchain technology. The core of Ethereum is a peer-to-peer (P2P) network, and the Ethereum blockchain database is maintained and updated by numerous nodes connected to the network. [0003] figure 1 It is a schematic diagram of Ethereum block mining in the prior art. Such as figure 1 As shown, the transaction fee is collected by the nodes, and the user (Miner) 12 is the node that collects, disseminates, confirms and executes the transaction in the Ethereum network 10. Users package transactions into blocks and compete with each other to have their blocks added to the next blockchain, a proces...
