This has been a long time in the making; it feels so great to finally be able to announce this. Native Bitcoin trading is an imperative. Permissionless global liquidity for the largest asset in crypto.

UTXO is proud to announce the development of the s402 protocol to bring an Agent Economy to Bitcoin. AI Agents can now launch + trade tokens and earn BTC as fees to further fund development. Learn more below 👇👇👇

@builtonbtcpod @spark this is very outdated 😉

A look at the current @spark ecosystem of live apps.

Meh; this is just misleading for no reason. Double spending on Spark requires every operator to retain old keys and collude with the previous sender. If one operator deletes their key share, the transfer is irreversible. tldr; 1/n trust with perfect forward security. Ark transactions start as preconfirmations where a single operator can double-sign competing claims. tldr; 1/1 trust. Spark is structurally stronger during this phase. Ark's finality comes from a batch round that settles on L1 at an interval. The "real finality" comes from an L1 tx, which all users cumulatively pay for. It's just a different priority set, that's all.

@visionario_btc "Con Spark nunca tienes la garantía de que tus transacciones son finales, siempre existe la posibilidad de que los operadores de Spark coludan con remitentes anteriores para hacer un doble gasto." Are you this is true? cc @spark @ethannmarcus @davidmarcus

La principal diferencia entre Ark y Spark (L2 de #Bitcoin): Con Spark nunca tienes la garantía de que tus transacciones son finales, siempre existe la posibilidad de que los operadores de Spark coludan con remitentes anteriores para hacer un doble gasto. En Ark siempre tienes la opción de darle finalidad a tus transacciones. Las transacciones inicialmente son preconfirmadas (con un modelo de confianza similar al de Spark), pero una vez que les das finalidad en una ronda puedes verificar tu mismo que tienes la misma garantía de seguridad que #Bitcoin capa 1. Ambos protocolos te ofrecen salir unilateralmente a la blockchain en cualquier momento, pero solo Ark te da la opción de tener finalidad real sin tener que bajar a la capa 1. @arkade_os @spark

A small group of people are building the tools that make Bitcoin do more than sit in a wallet. Proud of this circle. Congrats @ArkLabsHQ !

@revofusion 👀

My latest CVE bounty hit Ethereum, Solana, Sui, Polkadot and more at the same time. can't say much yet, will share details soon 👀

@LayerZWallet Beautiful

How fast can you receive a lightning payment without having installed a wallet or signed up anywhere? This is how @Layerzwallet does it!

@summraznboi 🐐

I know that getting as much Magic Eden off-chain data out before their shutdown is on everyone's top of mind, so I took the initiative to extract that data. Here I present the final data dump of all Magic Eden collection and attribute data: github.com/summraznboi/ma… Good luck!

@gray_newfield @GlMinoprio @USDCharm @flashnet @spark LFG!

ANOTHER ONE AGAIN??? Never stopping.

@AdamSimecka @MannaBitcoin x.com/sethforprivacy… And it’ll only get better

Spark is a fantastic protocol with tremendous potential. It's interesting to see all of the developers and apps integrating it. So why hasn't @MannaBitcoin? Well, one of the tradeoffs with Spark is privacy. Spark Entities have visibility of ownership changes, involved addresses/UTXOs, and transfer requests. In short, at best, they are honeypots. They can be compromised or hacked, and your data can be leaked or sold. I do believe Spark privacy will improve. We just aren't ready to integrate to a protocol that isn't fully private.

@guap_app So good
