This compact description is further combined with slashes prefixed by m or M to indicate hierarchy and key type, with m being a private key and M being a public key. This allows HD wallets to be used on an insecure server or in a receive-only capacity, issuing a different public key for each transaction. Bitcoin uses a specific elliptic curve and set of mathematical constants, as defined in a standard called secpk1 , established by the National Institute of Standards and Technology NIST.
