Zcoin (XZC) is an open source, decentralized privacy coin that focuses on achieving privacy and anonymity for its users while transacting on the blockchain. It pioneered the use of the Zerocoin protocol and also the Sigma protocol which replaces it, that allows users to have complete privacy over their transactions via zero-knowledge cryptographic proofs.
Unlike other zero-knowledge proof schemes, Sigma achieves this without trusted setup and uses only standard cryptographic assumptions.
Zcoin was also the first coin to implement Merkle Tree Proofs on its network for egalitarian mining, as well as the Dandelion protocol which protects user identities by obscuring their IP addresses.
Zcoin is listed on many world leading cryptocurrency exchanges such as Binance, Bittrex and Huobi.
