Abstract Most existing blockchain schemes are based on the design concept “openness
and transparency” to realize data security, which usually require transaction data to be
presented in the form of plaintext. However, it inevitably brings the issues with respect to
data privacy and operating performance. In this paper, we proposed a novel blockchain
scheme called Cipherchain, which can process and maintain transaction data in the form
of ciphertext while the characteristics of immutability and auditability are guaranteed.
Specifically in our scheme, transactions can be encrypted locally based on a searchable
encryption scheme called multi-user public key More >
