This is how money should work. User's balances never at risk, operators can only lose their own liquidity.
Replying to @secondhq
4/ User funds were never at risk because VTXOs sit on pre-signed exit paths the server can't spend. The only bitcoin the vulnerability exposed was our own liquidity. The design did its job, even if we'd rather have demonstrated it another way.
1/ The Bark plugin for @BtcpayServer is now ready for production. It's possibly the simplest way for a business to take self-custodial bitcoin payments (especially Lightning) on their online store, and you don't need to run a Lightning node to do it.
1/ Payjoin boards have been available in Bark for a couple of weeks now, so we thought it was time to take a closer look at what they can do: boarding direct from external wallet apps, saving the user fees and time, and the same trick applied to on-ramping into Cashu mints.
1/ It's hardening season. Bark 0.7.0 is all about improving security and reliability. There's nothing more important to be working on right now. Thanks again to @ProjectLoupe and @theinstagibbs for the disclosures behind several fixes.

.@grok bought me a @DoorDash gift card from @bitrefill using bitcoin from a locally running Bark wallet.
All autonomously.

Novak Djokovic in his documentary on why he refused the COVID vaccine:
"Because I didn't need it. Why should I get the vaccine? I'm healthy, I'm an athlete. I had corona. I had immunity. I wasn't a threat to anyone. There was no reason for me to get vaccinated. It's my freedom to choose which that fundamental right that you have as a human being on this planet — the freedom to choose — which was taken from a lot of people."

Kimi K3 unleashed is... terrifying.
It's one thing to scan codebase for security issues (which Claude and OpenAI block). It's another entirely to launch a fleet of AI to actually hack your service.
The normies and fiaters truly have no idea what is about to happen.
1/ Wallet apps built on Bark have never done their own Lightning pathfinding: the Ark server works out the best path on their behalf. It works great, but some users want more control, or don't want to share destination data. New research from @notgrubles explores an alternative.

Today is the day we premiere our Bark integration for BTCPayServer.
This will allow any merchant to start accepting lightning payments, store them as VTXOs on disk, and withdraw their earnings to onchain.
Ark solves the inbound liquidity problem.

Join the amazing Bitcoiners @giacomozucco @mir_btc @stephanlivera @SenorEmilio @AlexLi98 @vryfokkenou @matthewvuk2 and many others in celebrating Bitcoin as MONEY! (Our @r0ckstardev is preparing some exotic pizzas (not approved by @giacomozucco ) and has a plan for a secret bar!
1/ Bark is now a Lightning backend option in Alby Hub.
@getAlby built the integration on the Bark SDK in record time, just days after our mainnet launch. You can now enable Lightning payments in your hub with no Lightning node, channels, or liquidity to manage.
Today I'm happy to announce Noah. ⛵
It's a Bitcoin wallet that @nitesh_btc and I have been working on, using the Bitcoin Ark protocol via @secondhq.
Noah and the Ark protocol allow easy onboarding, Lightning Address support, easy backups, fast payments, and much more, while staying trust-minimized.
With Noah, you can easily pay and receive via Lightning without dealing with channel management and inbound/outbound liquidity constraints.
Onboarding is as easy as receiving a Lightning payment. When you onboard, you get an Ark VTXO (akin to a UTXO but offchain) instead of a channel.
You can also onboard via onchain and internal Ark payments.
Each Noah user gets a Lightning Address that they can use to receive, even offline for Noah->Noah payments.
You can restore the wallet securely with just your seed phrase.
Noah is available now on mainnet! Please give it a shot and let us know what you think. ⚡️
SECOND IS NOW ON MAINNET.
Bark, our implementation of the Ark protocol, is available for anyone to start making bitcoin payments.
Included in the launch are our mainnet Ark server, the Bark SDK, and multiple wallets to try from day one.
