“Edge Firmware for Mk4 will be updated more frequently and contain the very latest in BIP’s and other upcoming tech for Bitcoin, but it’s not for everyday hodlers: it’s for the wallet developers and power users who are itching to experiment with new types of signatures, and complex new on-chain wallet types.” Disclaimer: “Do not use this firmware on your main stash. Do not run it to impress potential sexual partners.””Winning features from “edge” will be moved to the normal firmware only when they are ready, and we are still developing new and practical features on both branches. Isolating the riskier stuff allows us to concentrate on everyday features, that everyone can use right away, while the Bitcoin community develops supporting code for new types of signatures and consensus related changes.”
