Estimating wallets and bitcoins owned by Satoshi using Hash-rate and Transactions analysis

Abstract

Bitcoin is designed to allow its users to send and receive payments under a pseudonym. In Bitcoin, A pseudonym is an address from/to which a user sends/receives coins. Owing to users anonymity, one-half of the transactions in Bitcoin are associated with illegal trading or money laundering. Hence, it is necessary to develop an approach that estimates the number of coins owned by Bitcoin users and identifies transactions which deal with illegal activities. Considering that every address involved in the Bitcoin transaction is stored permanently in the ledger. If an address is ever mapped to a user identity, every transaction wrote by that user will be linked. In this study, we proposed a new method to identify the number of coins owned by users, in particular, we estimate the number of bitcoins held by the Bitcoin creator Satoshi Nakamoto, by analyzing the mining hash rate, mining reward and transactions data.
