Abstract

This study aims to apply security problems such as homomorphic encryption algorithm, elliptic curve
digital signature algorithm, and secure hash algorithms in building your own bitcoin virtual currency based
on the Blockchain system; while still ensuring the confidentiality and privacy of the generated bitcoin
virtual currency. The result achieved by the author team, who created their virtual currency bitcoin, has
integrated security techniques (including secure hash algorithms with a length size of 256 bits; elliptic curve
digital signature algorithm with a length size of 384 bits; full homomorphic encryption) and ensure privacy.
The bitcoin virtual currency created by the team of creators achieves these security and privacy properties
in Blockchain-based systems and applications.
