For example, they don’t allow for internal shielded transfers, can not interact with intelligent contracts, and customers have to operate in fixed denominations which means users can not successfully transact working with their protocol, with any sort of ease or efficiency. The core element that brings privacy and anonymity in RAILGUN is the utilization of Zero-Knowledge Proofs. To put it just, zksnarks is a proving system, and "zero-knowledge" signifies the verifier gains no information about the transaction’s sender, recipient or amounts, giving users comprehensive privacy and anonymity. If they’ve employed MetaMask or any other popular wallet it will be transparently familiar. Similar to how Zcash works, RAILGUN utilizes zk-SNARKs to prove that shielded transactions are valid devoid of revealing any facts about the sender, the recipient or the transaction quantity. Furthermore, it is open-source so any person can audit it at their own will. All the complicated tasks are handled by the wallet itself, with no added complexity to the customers. Once the proof is verified by the clever contract, then it updates the Merkle tree which accumulates all generated notes (i.e. encrypted balance owned by a public-key controlled by the recipient), and nullifies the consumed notes (i.e. owned by the sender). They won’t have to worry about how the zk-SNARK proofs are generated or verified or how the RAILGUN sensible contracts safeguard their privacy. Railgun comes with what users have come to expect in terms of a modern user knowledge. This prevents customers from double-spending or making revenue out of thin air.
