Yosh, this is markstr, a POC for Nostr-based oracle resolution for prediction markets on Bitcoin, showcased on Mutinynet signet with CTV and CSFS activated. The outcome resolution script looks like this: <outcome_message_hash> <oracle_pubkey> OP_CHECKSIGFROMSTACK The oracle needs to sign a particular Nostr event (with a content like: PredictionMarketId:SJ1IPWRX Outcome:Yes - Bitcoin above $100k Timestamp:175284641) and the outcome resolution is then verified onchain using CSFS opcode. The witness for the taproot script path will then be: signature (of the outcome hash / Nostr event id), script (resolution script shown above), control_block.

I was chatting with the @getAlby team about their Lightning MCP server using Nostr Wallet Connect. Forked it to integrate Lightning <> Starknet atomic swaps via @atomiqlabs SDK. In the demo, I fired up Claude Code and asked it to handle an end-to-end swap: "swap 311 sats to STRK". It executed perfectly, pulling from my @primal_app wallet via NWC connection string and performing the . Fully trustless (HTLC reverse submarine swap). Exciting times for building Bitcoin apps with AI. 🧡

Your exchange knows your balance. Your IP. Your withdrawals. Your habits. Your risk. That’s not custody. That’s surveillance. COLDCARD fixes this.
