Split-key vanity address
A split-key vanity address is a type of vanity address generated from one or more ECDSA private keys. The security of such solution is guaranteed by the properties of the Elliptic Curve Cryptography .
A split-key vanity address is generated by a specialised software, called a generator. One such sample generator is available as a part of the Vanitygen program suite.
Address generation outsourcing
Generating a split-key vanity address can be outsourced to a third party miner without risking your final private key being compromised. Moreover, work on such address generation can be distributed to many miners simultaneously through a use of a pooling service. One example of such a service is Vanity Pool.
