Author here: I built this because I kept finding ways to “renegotiate with myself” on weeks I didn’t feel like training. I wanted a commitment device with real consequences and no trusted referee — just code and incentives.

Write-up / architecture / threat model:

https://pedrooaugusto.github.io/blog/posts/making-missed-wor...

Current run parameters:

- Network: Arbitrum (Ethereum L2)

- Duration: 12 weeks (Jan 19 → Apr 13)

- Total stake: ~$235 (0.075 ETH)

- Penalty per failed week: ~$19 (0.00625 ETH)

How enforcement works:

- If a week fails, anyone can call enforceAgreement() and receive a share of the penalty; the rest goes to the Giveth charity.

- There’s also a Chainlink Automation backstop so “nobody enforced” can’t become an escape hatch. If automation is the first to enforce a missed week, there’s no caller to reward, so 100% of the fine goes to Giveth.

I’d love feedback on:

1) where you’d try to cheat this,

2) what would make it more verifiable/auditable to you.
