• P2SH (Pay-to-Script-Hash): A more complex address type that allows the creation of addresses that use multi-signatures or other script conditions.

Address Generation

Bitcoin addresses are generated from a set of private and public keys by using elliptic curve cryptography. The private key is a secret number and the public key is calculated from the private key and can be shared publicly. Addresses are generated by taking a public key and applying a series of hash functions against it.

Address Security
