  "content": "🆕 I've built two more demos for state machines on #nostr — this time involving #cashu, with a few interesting use cases around custody and betting. ⚡\n\nIn addition I've made the explanations more verbose and understandable, and rendered a video for every demo with Remotion 🎬. The actors are now generatable per demo and persist across sessions.\n\nEnjoy on https://schlaustronics.com/nsm 🚀\nSource: https://github.com/zeSchlausKwab/nsm 🔗\n\n—\n\n/nsm/wager - Wager · decentralized escrow\nThe custodian holds nothing. Bettors lock stakes into 2-of-2 Cashu multisig and pre-sign every possible outcome; the oracle's only power is choosing which pre-signed package gets the second signature. The mint enforces — no party can steal.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/481baf3e1848f676570650cae6233850d1183595b267ab9d77552f361113936c.mp4\n\n/nsm/bet - Bet · oracle-resolved betting\nTwo bettors stake Cashu against an outcome. An oracle publishes what happened, and a payout scroll computes the winnings deterministically. Anyone replaying the chain can re-run the scroll and get the same numbers.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/e86a0e2c8eea98ea3f335ab0e9aaab07bee2f696b2afce0dcf9090f22f2d38fe.mp4\n\n/nsm/counter - Counter · the smallest interesting state machine\nTwo players race to a target on a shared counter. Every interaction is a signed Nostr event on a single relay — no APIs, no shared database, no off-band coordination.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/b001c9b59cb852cf58c5cc391e6adc7da9daa16fbc90daf08def578eee4cfba6.mp4\n\n/nsm/rps - Rock Paper Scissors · fair play via commit-reveal\nBoth players publish a sha256 commit of their move before either reveals. The custodian re-hashes each reveal to verify it matches the prior commit before snapshotting.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/0d33dc8d6d70d993200ef4ff6df8090e7a4c49af4f49cbdf83f9eb24dc244368.mp4\n\n/nsm/vote - Vote · time-driven voting\nA roster of voters casts yes/no until the deadline. The custodian fires CLOSE_VOTING and FINALIZE herself — but both are gated by the SM's own deadline guard, so any watchtower can verify she didn't close early.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/8fc3d0e0312759bdc636697ca602c69bf8daffe00582da346c8d67b392d75de3.mp4\n\n/nsm/badges - Badges · transferable digital assets\nOne shared kind:7500 ownership state machine, many minted kind:7503 badges, each with its own ownership chain under d-tag = imageHash. Transfers require m-of-n validator cosigns.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/d88ea53672e7a6f1aa274540abcd2f7a1b640a13c88ab31fc365029d92582406.mp4\n\n/nsm/scroll-counter - Scroll Counter · state machine with pluggable rules\nCounter shape, but guards and actions are AssemblyScript-compiled WASM blobs (scrolls) published as kind:1227 events. Swap the engine tag, get different rules — the SM definition itself never changes.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/d6923d41c832d39b1ce36d3c7d8e59e78d6949859b43bf968e12e0c1444517a5.mp4\n\n/nsm/negotiator - Negotiator · propose, agree, spawn\nTwo parties iterate on a state machine definition until they agree, then a jukebox spawns the negotiated SM and reports the new machineId back. The negotiation transcript IS the contract.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/34a1625525bfa2feb3815b16dcdb79146457d8a2ff3211537b147e551f4b7228.mp4\n\n/nsm/nested - Nested · parent + child state machines\nA tournament parent SM invokes two child match SMs. Every snapshot carries the children's live state alongside the parent's — readable straight off the relay, no extra subscriptions.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/0aa41ab712a7c3ea4436a47abb57f0fd43cdce6c98ec77671564c1561fbcb3fd.mp4\n\n/nsm/pool - Pool · decentralized-custody crowdfunding\nThree stakers lock Cashu P2PK to a target with a refund timelock back to themselves. Majority yes funds the target; the custodian never touches the money — the mint enforces everything.\nhttps://npub182jczunncwe0jn6frpqwq3e0qjws7yqqnc3auccqv9nte2dnd63scjm4rf.blossom.band/3b6cee938a2c054f83a2c1eb79faf8d46b5b4c7f263454d94fbbe77b89da5118.mp4\n\nnostr:nevent1qqsfpwsnyy59rjmthl5uw24suyflyek5h00w069pepy857j4e7vmqsgprfmhxue69uhhyetvv9ujuampwejkvatwvvhxc6tkv5hsygp65kqhyu7rktu57jgcgrsywtcyn583qqy7y00xxqrpv672nvmw5vpsgqqqqqqsuxlxw6",
