Rendering is the process of creating images, animations, and videos by simulating the behavior of light and materials. The demand for rendering has grown significantly in recent years due to the increasing use of computer-generated imagery (CGI) in film, television, video games, and other forms of media. The demand for high-quality, photorealistic images and animations has also led to the development of more advanced rendering techniques, such as ray tracing and global illumination, which require significant amounts of data processing power.

Blockchains are decentralized digital ledgers that are used to record transactions across a network of computers. They are the technology behind cryptocurrencies such as Bitcoin, but have the potential to be used for a wide range of other applications as well. One of the key features of blockchains is their ability to enable trust and transparency in digital transactions, without the need for intermediaries such as banks.
