Subnet 20: GroundLayer
GroundLayer is Bittensor Subnet 20, built to serve as the capital layer for the broader Bittensor ecosystem. Rather than producing AI outputs or performing inference tasks, GroundLayer addresses a structural gap in the subnet economy: the need for orderly, transparent capital formation around subnet alpha tokens. The subnet is operated by RogueTensor and its website is at groundlayer.xyz.
The core problem GroundLayer targets is that subnet operators often need to raise capital, but selling alpha tokens on the open market creates immediate downward price pressure that can undermine investor confidence and long-term network health. GroundLayer resolves this by replacing informal handshake deals with smart-contract-enforced OTC structures — standardized terms, locked schedules, and aligned incentives for all parties.
How the Mechanism Works
GroundLayer’s incentive mechanism revolves around a three-party model: subnet token sellers (operators raising capital), fund managers (the competitive mining layer), and investors (who commit capital through fund managers).
Subnet operators define deal parameters upfront — the quantity of alpha tokens available, the discount offered relative to a pricing reference, the lock schedule governing when tokens are released, and an expiry date for the deal. These terms are enforced on-chain, eliminating the counterparty risk and ambiguity that have historically plagued private OTC arrangements in the Bittensor ecosystem. According to GroundLayer’s published thesis, this design allows subnets to raise capital without any spot selling pressure on their token price.
Fund managers act as the subnet’s miners. They compete by sourcing and committing investor capital into available deals, and their standing within the subnet is determined by the total AUM they have successfully locked into active deals. Validators measure this locked AUM and score miners accordingly, using Yuma Consensus to distribute emissions toward the fund managers who demonstrate the greatest capital deployment and deal performance over time.
Investors participate by routing capital through fund managers they trust. Because all deal terms are recorded and auditable on-chain, investors can verify parameters independently before committing. Fund managers have a direct incentive to select high-quality deals: their emissions scale with locked AUM, so growth in assets under management directly increases their share of subnet rewards.
This design means that every party has explicitly aligned incentives — operators raise capital without disrupting their token’s market price, fund managers earn in proportion to their performance, and investors receive structured, discounted exposure to subnet tokens under clearly defined terms.
Participating as a Miner
Miners on GroundLayer take the role of fund managers within the OTC marketplace. Participation centers on sourcing capital from investors and deploying it into active deals structured by subnet operators. Performance is measured by locked AUM — the total value of capital successfully committed and held in deals.
Prospective miners should visit groundlayer.xyz to apply for early access and monitor the subnet’s documentation as GroundLayer moves toward full public launch. New participants should expect an initial evaluation period before receiving emissions, as validators need time to assess activity across the miner set.
Participating as a Validator
Validators on Subnet 20 are responsible for measuring and scoring the fund managers competing for emissions. Their primary task is to evaluate each miner’s locked AUM across active deals and translate that into weight assignments that feed into Yuma Consensus.
Accurate scoring is essential to maintaining the integrity of the fund manager competition. Validators who set weights that reflect true deal participation and capital commitments earn their own emissions, while validators whose weights diverge from network consensus are penalized through the standard Bittensor accountability mechanisms.
On-Chain Identity
Subnet 20 is registered on the Bittensor network under the name GroundLayer, operated by RogueTensor
under owner coldkey 5FuzgvtfbZWdKSRxyYVPAPYNaNnf9cMnpT7phL3s2T3Kkrzo. The subnet supports 256
neurons and its official website is groundlayer.xyz. Live on-chain data
including metagraph state, neuron counts, and alpha token pool information is available at
taostats.io/subnets/20.
Relationship to Yuma Consensus
Subnet 20 uses Yuma Consensus to convert the locked-AUM weight assignments that validators submit into the per-block TAO emissions distributed to fund managers on the network. The Yuma Consensus documentation describes how validator weight submissions are aggregated into consensus weights for each miner registered on the subnet.
In GroundLayer’s context, validators do not evaluate model outputs or forecast quality — they measure the locked AUM that each fund manager has committed into active deals and translate that into weight assignments. Yuma Consensus aggregates those weight submissions from all active validators into a single consensus ranking, ensuring that individual validator measurement differences do not distort the overall emission distribution. Fund managers whose capital deployments are consistently measured and weighted highly across the validator set earn the largest share of per-block emissions.
Development Stage Context
The Introduction to Bittensor describes subnet development as moving from localnet to testnet and then mainnet. For GroundLayer (SN20), that sequence applies to the standard Bittensor lifecycle: localnet for isolated development, testnet for shared non-production testing, and mainnet for live operation with real emissions.
On mainnet, GroundLayer (SN20) is registered as the live production subnet at netuid 20. The Bittensor Networks reference separates mainnet, testnet, and localnet. Participation examples or emission outcomes from one environment should not be read as representing production subnet performance in another environment.
Miner and Validator Roles
Subnet 20 operates under the standard Bittensor two-role structure. Miners supply the subnet’s capability and validators evaluate those contributions and set weights. Reward distribution follows Yuma Consensus.
Reader Boundary
Subnet 20 GroundLayer should not be read as generic Bittensor subnet documentation, an AI inference subnet, or proof that informal OTC deals are equivalent to on-chain structures. It names one subnet’s on-chain OTC capital layer for subnet alpha tokens on netuid 20 (Understanding Subnets, Glossary: Netuid).
On-Chain Deal Terms Replace Informal Arrangements
GroundLayer’s published thesis describes deal parameters such as token quantity, discount, lock schedule, and expiry being enforced on-chain rather than through private handshake terms (groundlayer.xyz).
That structure is meant to reduce counterparty ambiguity in subnet alpha fundraising.
Locked AUM Determines Fund Manager Standing
Validators measure the capital fund managers lock into active deals and score miners from that deployed amount (groundlayer.xyz).
Emissions therefore track committed deal capital rather than model or inference output quality.
Validator Weights Still Flow Through Yuma Consensus
Subnet 20 uses Yuma Consensus to convert validator weight submissions into emission shares each tempo (Yuma Consensus, Emission).
