Numerous variations exist, including printing the marks using a raster of lines in one direction on a background of lines in another direction, or using fine line patterns that alias into a visible moire pattern when copied. This makes it possible to see a pattern that had been invisible. This means that if a grey region consists of a grid of very small dark dots the filtering will produce a lighter grey, while a region of larger dots will be affected differently ("big-dot-little-dot"). In addition, human vision is sensitive to luminance contrast ratio. Features smaller than the resolution will also not be reproduced. It will also not be perfectly aligned with the directions of the document, causing aliasing.

A scanner or photocopier will act as a low-pass filter on the original image, blurring edges slightly. Void pantographs work by exploiting the limitations and features of copying equipment. Typically they spell out "void", "copy", "invalid" or some other indicator message. Normally these are invisible to the eye, but become obvious when the document is photocopied. Pantograph even turns your Instagram Images to Blockchain Assets and monetizes them through auctions.In security printing, void pantograph refers to a method of making copy-evident and tamper-resistant patterns in the background of a document. Communities can build announcement channels, chat rooms, or even send gifts to encourage followers with the lowest cost and no transaction fees. It is where users can send Blockchain assets while chatting with others. Pantograph is a Blockchain Application that built on TomoChain. All you can find on a Block Explorer is addresses, and activities with no specific identities. Blockchain Application will protect users from leaking personal info, as it encrypts everything.Everything is transparent, we can track anything with a Block Explorer.It is self-executing, so we can reduce human errors.Blockchain will store most data (text, images, etc.) forever in an order of time.The app will operate on those Smart Contracts, as it is a inseparable part.Ĭreating Blockchain Application will have some advantages: However, during the process, developers have to create and implement one, or multiple Smart Contracts. This enables developers to build financial apps, or games, or similar types of apps that facilitate Blockchain Technology.įundamentally, the process of creating Blockchain application is similar to the process of creating normal applications. It means when a certain condition is reached, the system will provide a result that programmed in the Smart Contract. The nature of Smart Contract is self-executing.
