We are creating a huge body of articles and videos that explain everything you need to know to be able to build apps on Bitcoin SV, with or without Money Button. In the first documentation group, we outlined basic technical preliminaries including numbers, elliptic curves, and basic encoding tools that are used in Bitcoin and applications based on Bitcoin.
In this second group, we introduce private keys, public keys, addresses, and ECDSA (Elliptic Curve Digital Signature Algorithm), and everything else you need to know about keys and signatures in Bitcoin and applications based on Bitcoin. This information is extremely useful for anyone building or dealing with wallets. Here are those videos.
