Picture this

Who it is for

Kofi is learning jazz piano. Each session he uploads a 30 second clip hash and peers spot check random ones; after two years his Practice Log shows 1,840 verified hours, which gets him into a conservatory that cares about grit.

Why it is new

What exists today, and what this does differently

What is new

Practice logging onchain exists in student projects; peer spot checks on cumulative hours are uncommon.

Closest things out there

Proof of Practice (Solana devnet) mints learning milestones from practice logs, and BSV BRC-168 commits weekly hours with optional countersigning; no peer-verified hour ledger found live.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

The pitch, ready

Every hour of deliberate practice, timestamped, peer checked and owned by the learner.

Problem: Self taught musicians, athletes and craftspeople put in thousands of hours nobody sees. Schools and scholarship panels ask for evidence, and the best most people can show is a private notebook.

Solution: Each session commits fingerprints of clips recorded at random minutes. Peers spot check a sample and sign verdicts as attestations; verified totals are attested monthly so a school checks one record.

Why now: Cheap attestations on Base, email wallets and audio fingerprinting make a trustworthy practice record practical on a phone.

Market: Music, sports and craft learners worldwide, plus the teachers, academies and scholarship programmes around them.

The ask: Pilot with three West African music schools and a scholarship partner.

Funding is never guaranteed. Check each program's rules.

For hackathons and demo days

Your 2 minute demo

Home: meet Kofi in Kumasi at dawn, two years of jazz piano and only a notebook.
Practice: commit a 72 minute session, then watch a padded three hour loop get caught.
Check: listen to Esi's violin clip and sign a verdict.
Ledger: hit the Portfolio paywall, pay in USDC, attest October.
Profile: send the verified record to the conservatory.
Owner Agent: the looped recording that fooled the meter, and the fix.
Owner Revenue and Studios: change the Portfolio price, approve an academy, decline an hour seller.
Owner Growth and Roadmap: run a practice month, then request sports and crafts.

Many hackathons require code written at the event. See the Regatta Boardfor each race's rule.

BLUEPRINT

Why it matters and how it really works

The need

Self taught musicians, athletes and craftspeople put in thousands of hours that nobody sees. Schools, coaches and scholarship panels ask for evidence of sustained practice, and the best most people can show is a private notebook. A record that is checked by peers, and owned by the learner, is hard to find.

What exists and what is new

Parts of this exist. Proof of Practice, a Solana devnet project, mints learning milestones from practice logs, and BSV BRC-168 commits weekly practice hours with optional countersigning. Research verdict: rare, medium novelty. What this app adds is random-minute clip fingerprints plus a peer spot check queue on cumulative hours, with rejected sessions kept visible. It is a modest combination of known pieces, not a new primitive, and we did not find a live peer verified hour ledger.

The data it runs on

Per session: start and end time, skill tag, and SHA-256 fingerprints of 1 to 3 short clips recorded at minutes the app picks. Peer verdicts signed by checkers. Monthly hour totals as attestations. Audio stays on the learner's phone and is shared only with the assigned checker for that clip.

1.The mission

Let anyone turn their quiet daily practice into a record they own and that others can trust.

2.Why people can't resist it

The counter A verified hours number that only goes up when real practice is heard. People open the app just to watch it move.

Check two, get checked fast Checking peers earns credits that move your own clips up the queue. The circle keeps itself honest.

Rejected stays visible A failed session is struck through, not hidden. That honesty is what makes the total believable to a school.

3.How it works for real

Wallet: Privy embedded wallet on Base (or Solana), created at sign up with email. No seed phrase for the learner.

Session commitment: When a session ends, the phone hashes each random-minute clip and sends one transaction with the hashes, duration and skill tag to a small session registry contract. Gas is sponsored by a paymaster.

Spot check queue: A server picks 1 in N sessions using a verifiable random seed and routes one clip to a checker in the learner's circle. The clip travels encrypted and is deleted after the verdict.

Peer verdicts: Checkers sign a yes or no as an EAS attestation that references the session. Disagreement sends the clip to a third checker; hours drop only on two no votes.

Loop and repeat detection: An audio fingerprint (for example Chromaprint) compares the clips in a session and against the learner's past clips to catch loops before a human listens.

Monthly attestation: Once a month the verified total is attested on Base via EAS, so a school can check one record instead of hundreds of sessions.

Summaries: A small model such as Claude Haiku or Gemini Flash through OpenRouter writes a short weekly note from the session data. It never changes hours or verdicts.

4.Cost per use and pricing

A session commitment on Base is typically a fraction of a cent in gas; an EAS attestation is similar. A weekly summary on a small model costs well under a cent. Clip relay storage is tiny because clips are deleted after checking. Example month with 1,000 active learners at 20 sessions each: about $20 to $60 sponsored gas, $5 model, $25 hosting, under $100 total.

Learner Free

Log sessions, be checked, check others, and keep a private hours record.

Portfolio $4 a month

Public or link-shared profile, monthly attestations, and an export a school or coach can verify.

Studio $29 a month

For teachers and academies: a private checker circle, student dashboards and term reports.

5.Growth loop

Every shared profile shows who checked the hours, and checkers need their own circle, so each learner invites a few peers. Teachers bring whole classes through the Studio tier, and every verified profile sent to a school is a quiet advert.

6.Risks and guardrails

Gaming: Random minutes and fingerprints raise the cost of faking, but a determined person can still play badly on purpose for hours. The record shows effort, not skill, and should say so.

Collusion: Friends can approve each other. Rotating checkers outside a pair and flagging closed loops reduces this; it does not remove it.

Privacy: Practice audio can include family and home sounds. Clips stay on the phone, go only to one checker, and are deleted after the verdict.

Overreliance: Schools should not treat hours as a ranking. The app should present them as one piece of evidence, never a guarantee of admission.

Checker fatigue: If too few people check, the queue stalls. Check credits and a 1 in N rate the owner can tune keep load to about two clips a week per person.

8.Where this is going

Now
Musicians in small circles log and check each other's practice, and share a verified hours profile.
Next
Teachers and academies run private circles, and more skills join: languages, sport drills, coding katas.
Later
Scholarship panels and coaches read verified practice records directly, alongside auditions and interviews.
The world it builds
Effort that used to be invisible becomes a credential anyone can earn, whatever school they could afford.

OWNER PLAYBOOK

Own it, then chart your voyage

Nine routes from one vessel. Tap a port to open its chart.

Why own Practice Log

Practice Log turns your hours of deliberate practice into history you can prove. Owning it means the learners, teachers, and schools you bring in are your community, the fees are yours, and the record of every verified hour is anchored to your app. On someone else's platform, your learners' grit lives in their database.

What’s stopping you?

“I can't code.”

You do not need to. Practice Log ships ready to deploy, and every path here is written for non coders. When you want to change something deeper, you can hire help or ask DEPLOYR support.

“Is it really mine?”

Yes. It is deployed from your wallet, the contract address is public, and the brand, users, and revenue are yours. DEPLOYR does not hold your keys or take a cut of your app's revenue.

“What if people fake their hours?”

Peer spot checks on random clips make faking harder, not impossible. Be honest that it is verified practice, not a guarantee.

“What if nobody cares about verified hours?”

Start with teachers and coaches who already ask students to log practice. They see the value first.

“What about privacy of clips?”

Only hashes go onchain. Clips stay with the learner unless they choose to share them for a spot check.
