Hone

SN5 Hone is a programming exam with sealed answers, where an exam board mails out a coding problem, the examiners lock in every candidate's answer before the hidden test cases are revealed, and full marks are the only marks.

The commodity, explained from zero

What the subnet produces is a record of coding problems, the programs written to solve them, and a verified pass or fail for each. The README says it holds "the validator for RLVR on Bittensor Finney, NETUID 5" and leaves RLVR unexpanded. Problems arrive from "a private problem server"; the README says plainly that "Problem construction is not part of this repository". The design document mentions "exported dataset labels", which is the nearest the materials come to naming an output (inferred from docs/DESIGN.md).

Why such a record would have a price, and who would pay, is not stated. There is no product page, no price, no customer and no contact address. The chain description is the two-word tag "Hone training". Here the exam comparison breaks: a real exam board exists to certify students for someone, while the materials do not say who reads Hone's graded papers or what they are for.

Why it is on Bittensor at all

The materials do not say what decentralization changes here; on that question the honest answer is nothing yet, or nothing stated. What the design document does describe is a trust model: each validator "accepts no remote grading claim" and runs every submitted program in its own sandbox, so neither the problem server nor any miner can set a score.

How the work gets done

A validator, the examiner, leases a public coding problem from the problem server and sends it, signed, to half of the miners currently serving. Miners, the candidates, return a Python or Rust program; the included demo miner simply forwards the problem to a hosted GLM-5.2 model. The validator commits the exact set of signed answers to the server, and only then receives the hidden test cases, so no test can leak into a prompt. It runs every answer in a locked-down container with no network access, and a program that passes the whole hidden suite scores between 0.95 and 1.0 with speed as the tiebreaker; anything else scores zero. Each miner's last 200 results feed the weights that split emission, the subnet's share of newly minted TAO, and the owner's cut is set to 0%.

How you would know it works

The only artifact is the dashboard at honedashboard.com, titled "Hone Network · Miner Performance", which promises median accuracy, response rate and latency per validator. To a fetcher it reads "Waiting for aggregate data" and "0 registrations"; a reader needs a browser. There is no dated benchmark, sample output or usage figure.

What is missing

There is no miner guide, only a demo that calls a paid third-party model and defaults to the test network, plus five sample challenges. No hardware or competitiveness statement exists for a miner that wants to win; the registration cost is not stated (about 0.14 TAO on chain on 2026-09-09, with 243 active miners). The chain contact and discord fields are empty. The README calls the project "RLVR subnet" while the chain and dashboard say Hone. There is no plain-language paragraph anywhere, and the design document marks copy-resistant scoring as a TODO.

Metaphor: a programming exam with sealed answers. Every claim is drawn from the evidence set or the subnet's own materials; "(inferred)" marks a conclusion rather than a quote. Corrections.
