Beam
SN105Decentralised bandwidth network powering the open internet with distributed connectivity
Bandwidth is the internet's forgotten resource. Compute has Bittensor, storage has Filecoin, but moving data efficiently between systems remains controlled by a handful of cloud giants. Beam is building the open coordination layer for that missing piece.
// Decentralized bandwidth for the machine internet.
Beam is a decentralized bandwidth network on Bittensor that coordinates data transfers across distributed infrastructure. It lets anyone contribute bandwidth capacity and get rewarded based on how well they actually perform, verified through a mechanism called Proof-of-Bandwidth.
The simple version: It's like a decentralized Cloudflare for data movement, where anyone with spare bandwidth can participate and earn by reliably moving data between systems.
Centralized equivalent: Cloudflare, AWS Transfer Family, Fastly. All centralized, opaque on pricing, and closed to independent operators.
How it works:
- Miners (Orchestrators) receive transfer assignments from BeamCore, break large files into chunks, and coordinate workers to execute parallel transfers
- Validators read Proof-of-Bandwidth records generated by each transfer and set weights based on verified throughput, latency, and reliability
- The problem it solves: Global bandwidth capacity exists across data centers, ISPs, and independent operators but remains economically fragmented. There's no open market for it.
- The opportunity: AI pipelines, agentic workflows, and cross-cloud synchronization move enormous volumes of data. That demand is growing fast, with no open alternative to centralized CDNs.
- The Bittensor advantage: Performance-based rewards aligned to actual delivery metrics, not self-reported capacity. Any operator can join without a commercial contract.
- Traction signals: The website reports aggregate bandwidth of 847 Gb/s, 2.4 PB volume, and 1,247 miners as of the time of writing. The GitHub repo was updated in April 2026, and the subnet holds 7 active miners.

The internet's compute layer has been decentralized, and storage is getting there. Bandwidth, the actual movement of data between systems, has been left behind. Cloud platforms control routing, pricing is opaque, and independent operators have no way to participate in the market. Beam is positioning itself as the coordination layer that fixes this, starting with a focus on machine-to-machine transfers: AI pipelines, cross-cloud sync, and agentic workflows.
Mechanism:
According to the Beam GitHub repository and website, transfers flow through a three-tier architecture. Clients submit transfer requests to BeamCore (the central coordination layer). BeamCore assigns chunks to orchestrators by stake-weighted allocation. Orchestrators then coordinate workers via WebSocket, who fetch data from source and deliver to destinations. Each completed transfer generates a Proof-of-Bandwidth record. Validators read those proofs from BeamCore and use them to set weights on-chain, determining which orchestrators receive emissions.
Supported transfer patterns include single-to-single, fan-out (one source, multiple destinations), aggregation (multiple sources, one destination), and full mesh. Beam integrates with AWS S3, Google Cloud, Cloudflare R2, Snowflake, REST APIs, Webhooks, and MCP servers according to the project website.
The chain buy rate of 0.81% reflects active market demand coming alongside emissions, and the price is up over 196% in 30 days, suggesting a strong recent staking inflow. Emission share sits at around 1.24%, with a root proportion of 0.40, meaning organic staking makes up the majority of the pool.
- Execution: Only 7 active miners on the network. The infrastructure exists but real-world transfer volume is not independently verifiable from chain data alone.
- Centralization in BeamCore: The architecture relies on BeamCore as the coordination layer. If this is a centralized service, it introduces a single point of failure the README does not fully address.
- Competition: Decentralized bandwidth is a well-funded space (Filecoin, Storj, Akash). Beam's differentiation is its Bittensor-native performance incentives, but market positioning is still early.
- Liquidity: Market cap around 14,700 TAO with thin supply. Large exits would move the price significantly.
