Blindproof
Masked pieces, off-chain
Individual model operations run on masked values outside the subnet, including masked multiplication with two independent mask owners.
Roadmap · status as of 5 October 2026
One rung at a time.
Each rung must pass before the next one starts, and each one is published as evidence when it does. Everything runs in mock first, so real GPU time is only spent on a design that already works. Mainnet launch: Q1 2027.
- MQ3 2026Done
Local chain, mock miners
Attack, cheat, and load scenarios on a private Bittensor chain. 16 / 16 passed.
- TQ4 2026Done
Public testnet, mock miners
Subnet 575 on Bittensor testnet. Honest miners credited, lazy miner at zero, weights on chain. See the record.
- T+Q4 2026In progress
First earned incentive
Emissions running and validator staked; waiting for the first epoch to pay honest miners.
- T2Q4 2026Next
Full cheater sweep on testnet
Forged, late, nondeterministic, and withholding miners on the public chain, as already passed locally.
- G1Q4 2026Planned
One real GPU miner
Replace the mock server with the deterministic build of a mid-size open-weight model.
- G2Q4 2026Planned
Mixed-GPU agreement on chain
Miners on different GPU types return the same output hash and settle against each other.
- P1Q4 2026Planned
One real proof
A real zero-knowledge proof over one piece of the computation, settled through the same rail.
- A1Q1 2027Planned
Design-partner demo
A real workload from a first design partner, end to end on testnet.
- X1Q1 2027Planned
Outside operators
Independent miners and a second validator join the subnet.
- WQ1 2027Planned
Availability and slashing
Miners must keep proof data retrievable for a set window; random challenges and penalties enforce it.
- MNQ1 2027Planned
Mainnet launch
Launch in Q1 2027, with every rung above passed and published.
Where privacy fits
Masked execution is the research track running alongside the ladder. Pieces of it run off-chain today; it joins the testnet only after the real-model and real-proof rungs pass.
Gateway mode
Interactive. The client’s own gateway stays online and crosses each step live with masks from its own pool.
Capsule mode
Non-interactive. The client masks, submits, and goes offline; precomputed masking material carries the job. The harder construction and the long-term goal.
