Cryptocurrency Investigation - Blockchain basics



Published
Cryptocurrency investigation is much like other forms of financial crime investigation. Find transactions, find accounts and tie accounts to a real person. Cryptocurrency investigations are made somewhat easier since transactions are often public on a blockchain ledger. An investigator can analyze the public blockchain to investigate all transactions from a given account (wallet address). These investigations are similar to requesting transaction information from a bank. The major difference is that you don't need to request transaction information, since it is already public. However, it may be more of a challenge to tie an account to a specific user since there is no organization controlling who makes an account.
