The Challenge Hub season is over, and the winners have been drawn 🥳🥳🥳

One lucky winner takes home the Canyon Endurance CF 5, but there are more surprises across the prize list. Thank you to everyone who spent the season picking podiums with us and the Slovenian Cycling Federation 💙

Here is the draw, start to finish ⏬

3/ On Sapphire, a confidential contract can keep the details in encrypted state and publish only the result of the check.

The exchange gets its yes or no, and the rest of your history stays yours.

[Oasis 🌹 @OasisProtocol]

1/ Decoded: clean hands.

On a public blockchain, proving your funds are clean usually means showing where they came from, and that puts your whole financial history on display.

[Oasis 🌹 @OasisProtocol]

2/ A compliance check rarely needs all of that. It needs one answer: are these funds connected to anything they shouldn't be?

Cryptographic proofs can give that answer on their own, without revealing which payments, people or amounts sit behind it.

people still don't want strangers reading their messages, who would've thought?

In this clip from our community call, Ahmed walks through the Challenge Hub draw.

The full list of entries went onchain first, and you can click into the commit transaction to see the campaign information.

After that, the draw function picked the ten winners the campaign was set up for.

Chain of champions, spotted all over the crowd at the European Championships 🚴

The riders are done for the season, and focus is now on Privana, a private way to use your money built on Oasis tech.

It's in closed testing, and you can sign up for the waitlist here:

3/ A contract can then accept results only from code it recognises, and the operator can't change the logic without it showing.

For builders, it's a useful question to ask about any backend: what could a user verify about this code today?

[Oasis 🌹 @OasisProtocol]

1/ Many decentralized apps are only decentralized up to the point where they call their backend.

The contracts are onchain and anyone can inspect them, while matchmaking, AI features and reward eligibility often run on an ordinary server.

[Oasis 🌹 @OasisProtocol]

2/ Users are asked to trust that the code on that server is the code the team described. ROFL, the Oasis framework for offchain logic, runs that code inside a TEE that proves exactly what it is running, and Sapphire verifies that proof onchain before the app can act.

Trivia is on tonight in the Oasis Discord at 21:00 CET 🕘

Anyone can join and you don't need to prepare anything, though last week's winners would very much like someone to give them a challenge 😒

3/ There was no way to draw a second time, and the result is recorded onchain.

More than 20,000 tickets went into the draw, and anyone can check the outcome at https://t.co/LPd4OdZuy1

[Oasis 🌹 @OasisProtocol]

1/ Decoded: The Draw

2/ Most prize draws come down to trust. Someone runs the draw, announces the winners, and everyone assumes it only ran once.

For the Challenge Hub, we wanted a draw that nobody had to take on trust, including us.

[Oasis 🌹 @OasisProtocol]

2/ Before the draw, the full list of entries was committed onchain, which fixed who was in.

A single random number was then generated inside a secure enclave on Oasis, an isolated part of the processor that the machine's operator cannot read or change.
