# About Blockcast (old)

* Blockcast is a decentralized content delivery network 
* Through Blockcast’s open standard and hardware, people have the opportunity to become a CDN node operator, which is an important 
* The decentralized nature of Blockcast facilitates

Blockcast is a solution to the internet’s capacity problem, addressing the security and quality challenges around DePIN for content providers to deliver higher bitrate media in more places with crowdsourced direct-to-consumer multicast capacity. Storage is inexpensive, and so are mobile, home router, and televisions that are smart and secure enough to run a CDN node. As a result, millions of viewers can be served with a single stream, improving content delivery efficiency by orders of magnitude. Blockcast helps align incentives, vet and manage independent providers for enterprise grade delivery.<br>

The Open Capacity Marketplace provides a seamless way for CDNs to interface with major content providers using SVTA Open Caching’s standard interfaces. Content providers put out requests for capacity to CDNs operated by broadcasters, ISPs, or communities. Smart contracts and a distributed challenger network provide strong economic guarantees of security and service-level agreement enforcement in a trustless way. Revenue sharing from contracts provide the incentive structure for CDNs to offload capacity to independent node operators. Nodes are also rewarded for participating in challenges that verify the capacity and multicast coverage of node footprints, as well as service uptime. <br>

Where there are many registered challengers but no multicast coverage, a medallion can be minted offering boosted rewards to incentivize broadcasters and ISPs to race deploy multicast in high-demand areas in high-demand areas.
