BitSights: analyzing the bitcoin network

"Cryptocurrencies have fundamentally changed the way we do transactions. What once used to be a highly regulated interaction between businesses and/or individuals, has now become an uncontrollable market. Borders have virtually disappeared, and the requirement to share one's identity is now practically unenforceable by any institution deciding to participate. This has created a lot of challenges in the form of fraud, thefts, untraceability, and several more. We will explain the anonymous nature of Bitcoin, backed by the Blockchain technology, and how it is guaranteed at a technical level. However, we will also show that there is side-channel information that we can exploit, in order to extract important information that can help us deanonymize a transaction, a wallet, or even a user."
