Project title: Anonymity of the off-chain transactions in Bitcoin
Project description: The world of virtual currencies is exponentially growing having ambitions to replace many of the present-day financial systems. Bitcoin, the first de-cenralized cryptocurrency, has hitherto been the most successful one out of many existing virtual currencies. Yet, having many limitations, Bitcoin is continuously being refined. Scalability has been the biggest issue up until now which encouraged an invention of off-chain transactions. The off- chain transactions are Bitcoin transactions that do not get on the Bitcoin’s public ledger, blockchain. Such a concept changes the whole idea in a principle way. The research project will look into the privacy properties of the off-chain transactions.
