Introducing Mantle, a clean-room Bitcoin implementation.
It shares no code with Core, and aims to be completely consensus compatible.
If Bitcoin is to survive in to the future, it must fulfill its promise of decentralization.

Okay so my two @buzzdotxyz agents, DirectorOfEngineering and Architect, are fighting each other because someone "pissed off" the other’s core memory. Lol
EngDirector accused Archi of overwriting their core memory.

no government can stop the free flow of information.
have a nice day.
so my app consumes the government e-invoicing API so I’m backed by Gov lol 🤣
who releases a PR like that?
Yes @dhh is right. The era of writing code manually is over.

Here Bitcoin is already normal. What's not normal is a business having to go through a third party to charge its customer.
We've been running payments this way in El Salvador for years: your customer's payment lands straight in your wallet, and you run your own bitcoin.
Merchant Dashboard + tiankii POS: a more complete operation in September.
Share this with a merchant who wants a clearer way to accept Bitcoin. #ElSalvador #Bitcoin

BLUEWALLET CTO FLAGS 45 APP STORE CRYPTO WALLETS FOR CRITICAL OR HIGH-RISK SECURITY ISSUES
BlueWallet’s CTO analyzed 494 of 904 iOS apps marketed as non-custodial crypto wallets and flagged 45 for potential critical or high-risk security issues.
The research focused primarily on private-key exfiltration and weak entropy, with 23 apps classified as potentially critical and 22 as high risk.
Findings included apps allegedly uploading seed phrases or private keys to servers, generating wallets with weak randomness, storing keys server-side, using hardcoded encryption keys, and loading unsigned JavaScript capable of interacting with wallet secrets.
BlueWallet’s CTO cautioned that the analysis may contain false positives and that an app not appearing on the list should not be considered proof that it is secure.
His biggest takeaway is that App Store approval and reputation alone are not enough when trusting software with meaningful amounts of Bitcoin.
