DOTT.view🎥 (pay-per-view blockchain platform)

Entertainment, education, and media encounter content distribution and access control issues. Television and movie subscriptions, online streaming services, and e-learning platforms are centralised and dependent on intermediaries like payment processors and content delivery networks. Centralization can cause inefficiency, lack of transparency, excessive prices, and intermediary dependence.
In order to address these difficulties, we developed DOTT.view, a decentralised OTT platform built on the blockchain system. DOTT.view enables users to provide and access content and services while utilising the security, transparency, and immutability of blockchain technology.
