Theta is a piece of software that encourages a global network of computers to run a decentralized video streaming platform. Users now pay CDNs, which are geographically dispersed networks of operators, to deliver video streams. There are geographical limitations that prevent existing CDNs from keeping up with higher-quality streaming. Theta rewards its users for donating their excess bandwidth and computer power in order to relay videos.

Theta, in finance, measures the rate at which an option's price declines as it approaches its expiration date, reflecting the impact of time decay on options. It represents the amount by which the option’s value decreases daily, all else being equal. Theta is particularly important for options traders as it highlights the erosion of an option’s extrinsic value over time. For at-the-money options, theta tends to be higher, accelerating as expiration nears. Conversely, theta is lower for deep in-the-money or out-of-the-money options. While theta can be detrimental to long option holders, it can benefit options writers who profit from time decay. Understanding theta helps traders manage risk and make informed decisions about their options positions.
