An ethereum address is the last 20 bytes in the keccack256 of the general public critical. The public crucial algorithm is secp256k1, the same used in bitcoin. Because it is really an elliptic curve algorithm, the public essential can be an (x, y) pair corresponds to a point within the elliptic curve.
In the 1st posting of the collection, we generated a bitcoin private critical: 60cf347dbc59d31c1358c8e5cf5e45b822ab85b79cb32a9f3d98184779a9efc2.
