Hi everyone,
I've been working on this project:

It is still WIP. There may be bugs.

What Is This?What Is This?
Madame Satoshi's Bitcoin Fortune Oracle is a Lightning-native Telegram bot that blends the ancient mysticism of tarot with the mathematics of Bitcoin. For 21 sats, Madame Satoshi draws three cards from the Major Arcana and delivers a personalised Bitcoin fortune — each reading unique, each card a metaphor for your journey through the rabit hole.
Every draw is a permutation of fate: the order of the cards matters. The first card reveals a past influence, the second your present energy, the third your future outcome. With 9,240 possible permutations of the 22 Major Arcana, no two readings are quite alike.
How It Works
- Pay 21 sats via Lightning
- Receive an animated card reveal — three tarot cards flip over one by one
- Read your Bitcoin fortune, written in the language of the cards
- Win sats from the shared jackpot pool
Win Tiers
| Tier | Odds | Prize |
|------|------|-------|
| 🏆 JACKPOT!!! | 6 in 9,240 | 100% of pool |
| 🥇 MAJOR WIN!! | 66 in 9,240 | ~35% of pool |
| 🥈 MINOR WIN! | 666 in 9,240 | ~15% of pool |
The jackpot is shared across all players and grows with every draw. The rarest outcome — The Sun, The World, and The Magician, in any order — claims it all.

Every sat contributed goes directly toward building something the Bitcoin community can enjoy and eventually own.
It would be cool if you could somehow base the randomness for the game on new bitcoin blocks. I have no idea how this would work, but getting a fortune told by the next bitcoin block seems like a really fun idea.
That is a great idea! No clue how to implement it.. but I will def. give it some thought. Thank you!
I think maybe the seed for the randomness could be based upon: seed = hash(blockHash + userId + timestamp)
Need to think about how this will change things. If it introduces attack vectors... and how it will influence the eventual website which should also have session IDs and nostr integration... hmmm..
I guess, if it is a hash that combines the blockhash with with huserId and a timestamp.. should be okay.. no‽
You probably know better than I. In my mind, I was thinking that it would be cool to tie card flips to the block at chaintip so that with each new block cards have different likelihoods of being selected, but this may mess up how you have set up the game.
I think players would enjoy a feeling that at any moment a new block might be found that changes their odds in the game. Or something like this.
The odds should be fair, pardoning the house, ofc. ;)
Only using the block-hash as a randomness-seed doesn't make sense. Everyone would get the same cards.
Making a new hash to use as a seed for the randomness that is individual per user, based on the newest block + userid + long/strong timestamp might make it more enjoyable/personal.
If I try and implement it, I would like to make it verifiable. for users too.
I Need to think about that.
How to give users this ability?
I guess all they would need is the blockhash, their user id, and the timestamp that was used plus the hash that came from it to in turn produce the randomness of the draw.
I don't know how much space it would take in the TG bot's text baloon to add all that.
Perhaps a better plan for the website.. Or maybe add a command..
I need to think about it a bit more.. It should take up minimum space.
Maybe it could be represented as a short code-block that pre-presents them the command they could run in their own terminal or on some website?
For sure! I didn't mean to derail you, but it sounds like using some randomness from the most recent block could be cool.
