+## Bitcoin Knobs
+
+https://github.com/TABConf/bitcoinknobs
+
+Bitcoin Knobs is a fork of Bitcoin Knots that takes flexibility a step further. Where others decide what is "safe" or "reasonable," we believe in maximum choice. If that means your node refuses to start, your wallet vanishes into the void, or your peers pretend you don't exist, at least the decision was yours.
+ody sane would touch. Some people call that dangerous. We call it feature-complete.

+## Google wants to make sideloading Android apps safer by verifying developers’ identities
+
+https://www.androidauthority.com/android-developer-verification-requirements-3590911/
+
+- Google will soon verify the identities of developers who distribute Android apps outside the Play Store.
+- Developers must submit their information to a new Android Developer Console, increasing their accountability for their apps.
+- Rolling out in phases from September 2026, these new verification requirements are aimed at protecting users from malware by making it harder for malicious developers to remain anonymous.

+## Glock: Garbled Locks for Bitcoin
+
+https://x.com/AlpenLabs/status/1957808842558885902
+
+Glock is a primitive that enables the optimistic verification of any offchain computation on Bitcoin.
+
+Using garbled circuit-based locks, Glock drastically cuts onchain costs compared to today’s state-of-the-art, with a far simpler design. In its most compact variant, Glock25 achieves over 550x onchain efficiency over the BitVM2 verifier.
