Blockcast builds decentralized, community-owned content delivery network (CDN) infrastructure that uses single localized streams to reduce internet congestion and delivery costs. Growing out of UC Berkeley's TIER lab and its open-source Magma cellular core project, the company works with CDNs and ISPs to develop scalable, decentralized media delivery infrastructure.

Company profile
researched Aug 2026Blockcast is a decentralized content delivery network (CDN) built on the Solana blockchain. It aggregates network capacity from large numbers of geographically distributed, community-operated nodes to deliver high-bandwidth content such as live streams, 4K video, software updates and media releases. The stated aims are to reduce data consumption, rebuffering and latency, lower delivery costs for content owners, and ease congestion on internet service provider networks by deploying traffic servers closer to end users.
The company positions its work against reported growth in global internet traffic of 24% annually and live-streamed content accounting for roughly 17% of global traffic. Its roadmap following its seed round includes building out global content delivery capacity, expanding platform development, and launching a public testnet described by the company as the first decentralized multicast-enabled CDN. Blockcast also markets home "RELAY" nodes — compact servers that consumers can pre-order and operate to contribute to content delivery in exchange for weekly rewards.
Founding story
CEO Omar Ramadan previously built Magma, a mobile network core enabling operators worldwide to run 4G/5G networks for their communities; the project was acquired by Facebook and deployed to 500 sites over five years. After Helium adopted Magma and paired it with token incentives, reaching 17,000 sites in a year, Ramadan identified an analogous opportunity in content delivery networks, which led to Blockcast.
Business model
Blockcast operates a blockchain-based network in which third-party node operators contribute bandwidth and serving capacity and receive token-style rewards, while content owners and streaming platforms obtain content delivery capacity. The company has also opened pre-orders for consumer RELAY node hardware, which promises weekly rewards to operators.
Traction
Blockcast completed an initial seed round of $2.85 million and launched a pre-order campaign for its home RELAY nodes, with a public testnet and global content delivery capacity build-out planned.
Latest developments
Following the close of its $2.85 million seed round led by Lattice Fund, Blockcast said it would accelerate platform development, expand its presence in the networked infrastructure ecosystem, build out global content delivery capacity, launch its RELAY node pre-order campaign, and bring a public testnet online.
▸Full profile — market position, technology, go-to-market
Market position
Blockcast is an early-stage entrant in the decentralized physical infrastructure (DePIN) segment, applying community-operated node networks to content delivery infrastructure, an area its CEO characterizes as historically inaccessible to community networks.
Technology
The network uses the Solana blockchain to coordinate and incentivize tens of thousands of worldwide nodes, combining traditional broadcasting techniques with blockchain-based incentives. Blockcast has said it is developing multicast-enabled decentralized content delivery, and has worked on the security and service-level agreement requirements that major streaming platforms require in order to serve content from community-operated networks.
Go-to-market
Blockcast has pursued community participation as an acquisition channel, launching a pre-order campaign for home RELAY nodes alongside plans for a public testnet, and has publicized its seed financing and investor roster through crypto trade press.
Content owners and streaming platforms requiring high-bandwidth delivery, internet service providers affected by network congestion, and individuals or communities who operate RELAY nodes.
