Abstract: This disclosure relates to blockchain-based content verification. In one aspect, a method includes receiving, from a client device of a signer, a target transaction request for triggering presentation of a target electronic document. A smart contract for content verification of the target electronic document is invoked in response to receiving the target transaction request. A content verification program declared in the smart contract is executed. The executing includes reading content of the target electronic document from a blockchain and performing content verification on the target electronic document based on the content of the target electronic document read from the blockchain. A content verification result and the content of the target electronic document is returned to the client device for presentation to the signer.

Clickable antimicrobial polymers can be used to form coatings or films.

Abstract: Described herein is a rear view mirror system that is configured to adjust to a user's position without direct user interaction. In some embodiments, a camera may be included in the rear view mirror system so that its line of sight is perpendicular to a reflective surface. The camera may capture a digital image of the user. Eye patterns may be identified from the image information to determine an appropriate position for the mirror. In some embodiments, the mirror may be repositioned so that the camera's line of sight is directed halfway between the identified eye information and the center of a rear window. In some embodiments, the mirror may be re-adjusted periodically.
