Do tz1, tz2, tz3 addresses correspond to the different elliptic curves used by Tezos?
11
Yes, Tezos supports three types of keys associated with 3 kinds of elliptic curves
- tz1 for Ed25519 keys,
- tz2 for Secp256k1 keys (same as Bitcoin/Ethereum)
- tz3 for NIST P256 keys which may have led to some amount of controversy but is one of the most used elliptic curve, including native support in some mobile devices like the iphone
