Blockchain concept provided an inherent part of this decentralization together with hash-based proof-of-work, public key cryptography, and peer-to-peer network. Even though blockchain technology was introduced to solve the doublespending problem of electronic money without relying on a trusted third party, this particular concept is being researched and already used to solve problems in many other areas. This paper captures concepts of blockchain, its applications, issues, and suggested improvements referring to blockchain-related subsequent publications.

Crypto Identities: Simple and Anonymous Cryptocurrency Management

Nevertheless, we believe they still have a long way to go in order to replace regular currencies in day-to-day activities. A separate cryptocurrency wallet is required to hold coins and tokens of its type, which is also one of the complicated problems concerning managing multiple cryptocurrencies. Every wallet has at least one unique alphanumeric identifier address, usually twenty-six or more characters in length. Since the blockchain ledger is public, the user’s anonymity is protected using this address when transferring e-money. Communicating this address is also a difficult process. The current method to resolve the communicating complexity without compromising anonymity is to use a QR code, requiring a QR scanner app. Transacting with different coins with the same user requires communicating all of the different wallet addresses. With this research, we propose a solution to the multifaceted problems of executing peer-to-peer cryptocurrency transactions and managing varied cryptocurrencies, without compromising anonymity. We introduce secure and anonymous crypto identities with an open protocol to securely communicate identities over a communication medium, tied to any number of different cryptocurrencies.
