Cryptographic currency user directory data and enhanced peer-verification ledger synthesis through multi-modal cryptographic key-address mapping

A method, using a computer processor and physical memory, comprising:

• determining that a propagation packet is a transaction of a cryptographic currency propagating across a network for integration into a peer-verification ledger, the transaction comprising a value transfer of the cryptographic currency between an input key-address of an input of the transaction and an output key-address of an output of the transaction;
• extracting an IP address from a TCP/IP layer of the propagation packet associated with the transaction;
• extracting, from the transaction, a transactional hash associated with the input of the transaction, the transactional hash referencing a previous output of a previous transaction;
• analyzing the peer-verification ledger to determine the input key-address associated with the transactional hash referencing the previous output;
• extracting the input key-address of the input of the transaction of the cryptographic currency propagating across the network for integration into the peer-verification ledger;
• linking the IP address from the TCP/IP layer of the propagation packet with the input key-address of the input of the transaction;
• and
• designating, within an enhanced ledger data, the input key-address of the input of the transaction as under a suspected control of a user of interest based upon an association between the user of interest and the IP address extracted from the TCP/IP layer of the propagation packet of the transaction.

A system comprising:

• a collection server associated with an access point and having a computer processor and physical memory, to intercept an internet protocol packet determined by the collection server to have an association with at least one of a transaction of a cryptographic currency propagating across a network for integration into a peer-verification ledger and a key-bearing communication between a user of interest and a correspondent of the user of interest,
• an IP extraction module to extract an IP address from a TCP/IP layer of the propagation packet associated with at least one of the transaction and the key-bearing communication,
• a key extraction module to extract at least one of a transactional hash of an input of the transaction of the cryptographic currency propagating across the network for integration into the peer-verification ledger and a relayed key-address of the key-bearing communication between the user of interest and the correspondent of the user of interest,
• the network,
• a cryptocurrency network, and
• a directory server, to house at least one of a user directory data, an enhanced ledger data and a ledger copy data.
