Common questions.
See all →How are programs delivered?
Fully self-paced. You get lifetime access to video lectures, lab notebooks, and the program's cohort forum. A certification check is issued after the final project is reviewed.
Why do you only accept Bitcoin?
Because our students are crypto-native, and BTC gives us global reach without payment processors or chargebacks. An invoice is emailed automatically once the transaction is confirmed on-chain. We plan to accept stablecoins in a future release.
How is the payment verified?
When you complete registration you receive a unique BIP-21 payment URI and a live EUR→BTC rate. You broadcast the transaction from your own wallet. We then poll mempool.space for the txid and mark the payment confirmed as soon as the transaction enters a block.
What happens if I overpay or underpay?
Exchange rates drift slightly between the time the page loads and the time you broadcast. As long as you are within 1% we consider the payment valid. Larger discrepancies trigger a manual review — contact us with the txid and we will resolve it within one business day.
