Abstract: The present disclosure provides a digital currency transaction method and system, and related transaction terminals, and relates to the field of computer technology. A specific implementation of the method includes: exchanging, by a first transaction terminal, user certificates with a second transaction terminal to verify user identities of the two parties after establishing a communication connection with the second transaction terminal, negotiating with the second transaction terminal to generate a transaction factor after confirming that the user identity verification of the two parties succeeds, and uploading first digital currency transaction information including the transaction factor to a first operating institution back-end system, and sending, by the first operating institution back-end system, the first digital currency transaction information to a second operating institution back-end system to complete the digital currency transaction.

Abstract: A method of forming a pattern of doped region includes the following steps. At first, a device layout pattern including a gate layout pattern and a doped region layout pattern is provided to a computer system. Subsequently, the device layout pattern is split into a plurality of sub regions, and the sub regions have different pattern densities of the gate layout pattern. Then, at least an optical proximity correction (OPC) calculation is respectively performed on the doped region layout pattern in each of the sub regions to respectively form a corrected sub doped region layout pattern in each of the sub regions. Afterwards, the corrected sub doped region layout patterns are combined to form a corrected doped region layout pattern, and the corrected doped region layout pattern is outputted onto a mask through the computer system.
