Abstract

Embodiments include systems and methods for determining cryptographic address for a same entity across a plurality of distributed blockchain networks that use a same elliptic curve. In some embodiments the method includes computing a cryptographic address hash of the first cryptographic address using the cryptographic public key of the first cryptographic address, the cryptographic address hash being a common representation of the first entity on the first distributed blockchain network and the cryptographic address hash being derived via a cryptographic one-way hash function, the cryptographic one-way hash function following a protocol of performing a function on the cryptographic public key, the cryptographic public key being used on the first distributed blockchain network and a second distributed blockchain network, the first distributed blockchain network and the second distributed blockchain network using the same elliptic curve.

receive second distributed blockchain network data, the second distributed blockchain network data comprising a second cryptographic address on a second distributed blockchain network;

compute a cryptographic address hash of the first cryptographic address using the cryptographic public key of the first cryptographic address; and

correlate the first cryptographic address of the first entity to the second cryptographic address using the cryptographic address hash of the first cryptographic address, the correlating indicating that the second cryptographic address is of the first entity, wherein the correlating is based at least partially on the first distributed blockchain network and the second distributed blockchain network using a same elliptic curve.

2. The system of claim 1 , wherein the cryptographic public key is derived from a private key of the first entity using the elliptic curve.

3. The system of claim 1 , wherein the first distributed blockchain network and the second distributed blockchain network comprise one or more of cryptocurrency-based networks, virtual assets, virtual currencies, digital currencies, and cryptographic ledgers.
