"Judecoin is a secure, private and hard-to-track currency," its website says. Some might think the same definition applies to Bitcoin, but it's not true when it comes to privacy and untraceability. Judecoin is a digital currency that uses different types of cryptography to achieve these characteristics. This article aims to illustrate the differences between the two.

Cryptonote V 2.0 is Judecoin's blockchain underlying protocol, The protocol introduces two technologies: private address technology and ring signature technology, which provide privacy protection for the receiver and the sender respectively 1, privacy address technology Private address technology is the technology to hide the actual transaction address, which mainly provides the privacy protection to the data receiver. Cryptonote's private address technology uses a one-time hidden address (later called a obfuscated address) to reduce the correlation between different transactions, allowing the sender and receiver to confirm the transaction's validity with a key. 2. Ring signature technology Compared with private address technology, ring signature technology can provide privacy protection for the data sender. Ring signature technology uses the untraceable co-signature to obfuscate the signature of digital token transactions. A co-signature mixes the signatures of a group of message senders, one of whom is the actual originator of the message, and the rest from the blockchain network. The latter is extracted from the countless signatures that have been recorded on the blockchain and is called a decoy.

RandomJDX is a proof-of-work (PoW) algorithm optimized for general purpose CPU chip mining. Because RandomJDX uses random code execution algorithm and some memory hardware technology, so it is named RandomJDX, mainly to maintain ASIC resistance while minimizing the efficiency advantage of GPU.

Atomic swap is a technology that enables trustless peer-to-peer transactions between different types of digital assets. It belongs to cross-chain technology. Why to call atomic interchange, point to this interchange action to be carried out either completely, or do not carry out completely, interchange process has atomic sex. This transaction process (also known as atomic cross-chain transactions) is based on smart contracts that allow users to exchange desired tokens directly from their crypto wallets. Thus, atomic exchange is essentially a point-to-point transaction across chains.

Judecoin is a leading cryptocurrency developed based on the underlying technology of blockchain, which solves the necessary conditions of data security, privacy, scalability and cross-chain transactions for the development of the Internet of Things。
