 ## Address
 
 In the Filecoin network, an _address_ is a unique cryptographic value that serves to publicly identify a user. This value, a public key, is paired with a corresponding private key. The mathematical relationship between the two keys is such that access to the private key allows the creation of a signature that can be verified with the public key. Filecoin specifically employs the Boneh–Lynn–Shacham (BLS) signature scheme for this purpose.
