Targon (SN4) Supply Portal Goes Live
Manifold Labs announced the launch of the Targon (SN4) Supply Portal, a unified onboarding interface that lets compute suppliers monetize idle GPU and CPU capacity on Bittensor’s Subnet 4. The portal, accessible at supply.targon.com, gives datacenters and individual operators two distinct routes into the network: a permissionless path connecting directly to the Bittensor blockchain, and a Targon Managed path with weekly fiat payouts.
The launch targets a long-standing friction point in decentralized compute markets, where datacenters with idle hardware often lack the crypto-native infrastructure to participate in token-based incentive networks.
Two Paths to Earn on the Targon (SN4) Supply Portal
The permissionless route handles supplier onboarding directly through the Bittensor blockchain. Operators register hotkeys, configure their hardware, and start earning SN4 alpha rewards without intermediary contact. As Targon’s announcement put it, “no conversations necessary.“
The Targon Managed route takes a different approach. Manifold handles all blockchain operations on the supplier’s behalf, then issues weekly payouts in fiat or a currency of the supplier’s choice. This option specifically targets traditional datacenter operators who want compute revenue without holding or managing token wallets.
Both routes funnel hardware into the same confidential compute marketplace that powers Targon’s enterprise workloads.
Hardware Requirements for Confidential GPU Mining
The Supply Portal supports three confidential computing configurations:
- AMD EPYC 9xx4 series (Genoa/Bergamo) with SEV-SNP for CPU workloads
- Intel TDX paired with NVIDIA Hopper GPUs (H100, H200)
- Intel TDX paired with NVIDIA Blackwell GPUs (B200) in multi-GPU configurations
Each setup runs the Targon Virtual Machine (TVM), which deploys Confidential Virtual Machines on bare-metal hardware. This architecture provides end-to-end attestation for both the host server and attached GPUs, keeping workloads encrypted even on untrusted infrastructure.
Notably, the documentation flags BIOS access as a hard prerequisite. Operators without it face significant delays during configuration.
How Auctions Drive Miner Emissions on SN4
Miner emissions on Targon follow an auction model tied directly to public demand. Operators can query the current allocation per hardware tier through tower.targon.com/api/v1/auctions. Each tier (such as SEV-CPU-AMD-EPYC-V4 or TDX-NVCC-NVIDIA-H200) carries its own max bid, emission share, and minimum cluster size.
Critically, any emissions not allocated to active auctions get burned. This mechanism ties supply-side rewards directly to verified demand for confidential compute, rather than passive participation. Real-time miner weights, GPU counts, and payout data sit on stats.targon.com.
Targon’s Position in the Bittensor Ecosystem
Launched in October 2023, Targon ranks among the highest-revenue subnets on Bittensor and operates as the network’s confidential compute marketplace. According to Manifold’s own disclosures, the network now serves over 20 billion paid inference tokens daily across 1,500+ H200 GPUs, with more than $60 million per year in compute incentives flowing through the protocol.
On July 28, 2025, Manifold Labs closed a $10.5 million Series A led by OSS Capital, with participation from Digital Currency Group, Shopify CEO Tobi Lütke, early Google board member Ram Shriram, and both Bittensor co-founders. Manifold is led by Rob Myers, a founding Bittensor contributor, miner, and subnet designer, alongside President James Woodman, formerly COO of the Bittensor Foundation.
In March 2026, Manifold published a joint whitepaper with Intel titled “Decentralized Compute on Untrusted Hardware Using Intel TDX and Encrypted CVMs,” outlining the confidential computing architecture that the Supply Portal now operationalizes for hardware suppliers.
Why the Supply Portal Matters
The portal addresses one of the harder problems in decentralized compute: bringing datacenter operators who do not hold crypto into a tokenized market. The managed track abstracts the wallet, the staking mechanics, and the alpha-to-fiat conversion entirely. Meanwhile, the permissionless track preserves the original Bittensor ethos for suppliers who want full custody of their SN4 emissions.
Together, both paths widen the funnel for hardware participation in SN4 and tighten the loop between confidential compute demand and supply.

FAQ:
The Targon (SN4) Supply Portal is Manifold Labs’ onboarding interface for compute suppliers on Bittensor’s Subnet 4. Operators sign up at supply.targon.com, configure their hardware, and start monetizing idle GPU or CPU capacity through Targon’s confidential compute marketplace. The portal also tracks node status and earnings in one dashboard.
The permissionless path connects suppliers directly to the Bittensor blockchain, where they earn SN4 alpha rewards into their own hotkey. The Targon Managed path lets Manifold handle the blockchain layer and issues weekly payouts in fiat or a currency of the supplier’s choice. Permissionless suits crypto-native operators who want full custody, while Managed suits traditional datacenters that prefer abstracted token mechanics.
Targon supports three confidential computing configurations: AMD EPYC 9xx4 series with SEV-SNP, Intel TDX with NVIDIA Hopper GPUs (H100 or H200), and Intel TDX with NVIDIA Blackwell GPUs (B200) in multi-GPU setups. BIOS access on the host machine is a hard prerequisite, and storage minimums range from 1 TB (CPU) to 3 TB (GPU). Full setup scripts and firmware requirements live at docs.targon.com/providers/miner.
