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. Because freedom means being able to tune every setting, even the ones nobody sane would touch. Some people call that dangerous. We call it feature-complete.

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.
