What can you do with Monero style ring signatures for Nostr ? You can build an Anonymous Voting platform using Nostr identities to vote. Thanks to the Back's Linkable Spontaneous Anonymous Group, you can detect double voting without leaking identities. Check Ringable demo 👇 A client-side anonymous voting platform using Nostr-compatible ring signatures. Ringable allows users to create proposals and vote anonymously as part of a predefined group (a "ring" of public keys). It leverages the cryptographic power of bLSAG ring signatures to ensure that while votes are verified as coming from a valid member of the ring, the specific voter's identity remains hidden. The cryptographic functions are powered by the Nostringer Rust library, compiled to WebAssembly (WASM) for use in the browser. Live demo:

Introducing Nostringer - unlinkable ring signatures (SAG) for Nostr pubkeys. Instead of doing some Ghibli stuff I implemented a prototype of unlinkable ring signatures for Nostr. It's using Monero style Spontaneous Anonymous Group signatures (SAG). What does it enable ? Ring signatures allow multiple members of a group to sign a message without revealing which member actually signed it. I explored this after chatting with @Leo Wandersleb who wants to use this concept for WalletScrutiny. Basically his idea would be to let users write reviews as accredited wallet developers. Because of the competition between wallets it's better to not disclose who posted a review. It would be sufficient to know that it was posted from someone belonging to a group of accredited developers. Checkout the demo and repo in the links below. Live demo:

What about M31 arithmetic opcodes for efficient STARK verification on Bitcoin ? Idea: OP_M31ADD, OP_M31SUB, OP_M31MUL, OP_M31INV operating over the M31 Mersenne prime field. OP_CAT too generic ? OP_STARK_VERIFY too narrow ? This is something in between. https://hackmd.io/@abdelhamid/m31-opcodes-bitcoin-stark #bitcoin #starks #zkp

I asked Claude: what is the latest Bitcoin block ? And you know what ? He was able to give me the actual information about it. How ? Thanks to this Bitcoin MCP server I built. It works also with Goose (the new AI agent framework of @jack ). Find source code and demo videos below. Source: :

🪿 Goose is dope, very flexible. Was able to build a Goose Nostr extension (MCP server with SSE) very easily. It gives Goose the ability to post notes on Nostr basically. Censorship resistance matters, even for AI agents 😉 Code of the Nostr MCP server below. Cc @jack @fiatjaf

Cashu x STARKs ? Spending conditions in Cairo @npub12rv5...85vg ? Yes. Here is a video showcasing the generation of a STARK proof of some Cashu spending conditions defined as a Cairo program, and verified by the Cashu Mint. The STARK proof is generated using STWO. It enables to define arbitrary Cashu spending conditions easily, in a highly expressive manner, without breaking privacy and proving mathematical guarantee on the integrity of the computation. The spender define the spending conditions in Cairo. The receiver generates a STARK proof that conditions are met to spend the tokens. The Mint verifies the proof and completes the process if the proof is valid.

Any manga / anime fans here ? If yes tell me your top 3. Mine would probably be something like (but it’s very hard to keep only 3): - Dragon Ball (slightly biased because grew up with it, nostalgia plays a big part here but still it’s the father of all Shonens) - Shingeki No Kyiojin, the story is just incredible, the scenario is mind blowing as well as the foreshadowing and different grids of reading after discovering new elements of the story - Vinland Saga for the beautiful message and character development of Thorfinn, so many goated quotes in it (No one is your enemy. You have no enemies at all. / A true warrior needs no sword) #Nostranime #Manga
