About Blockcast
Blockcast applies DePIN to content delivery: node operators contribute bandwidth and storage so popular content is cached closer to viewers. It addresses the bandwidth waste of unicast streaming by converting requests into multicast between nodes, using the TreeDN architecture with source-specific multicast and AMT tunnelling to fan one stream out to many viewers, with RELAY nodes extending coverage and CAST nodes handling bulk traffic.
Demand comes from content owners, ISPs, broadcasters and commercial CDNs; supply comes from nodes in homes, campuses and data centres, with service levels enforced through proofs of resources and economic incentives. Rather than building new points of presence, it reuses existing edge capacity and reaches regions where fibre is hard to lay, including satellite and cellular links. Results depend on peering with ISPs and on how widely multicast is deployed.
Blockcast is a decentralized content delivery network (dCDN) on Solana for high-bandwidth use cases like 4K video, with its node network cutting costs by about 96% versus traditional architecture. In 2026 no new public funding or product milestone was disclosed; the project remained in active development (third-party databases updated to active in July 2026).
Future strategy and roadmap: Blockcast will keep refining its Solana decentralized delivery nodes and caching architecture, pursue media and live-streaming clients, and explore node incentives and tokenomics.
