Zcoin debuts Lelantus tesnet, the protocol offers high practical anonymity similar to cash

Zcoin today announced the testnet launch of its network, dubbed the Lelantus protocol.  The testnet will give users the opportunity to try out the new technology and provide valuable feedback as the project prepares for the mainnet launch by the end of 2020. The mainnet launch is slated for the end of 2020 and until then Zcoin hoped that users would try the testnet and offer feedback on the same.

With regard to Lelantus, Zcoin aimed to provide the “same” anonymity as cash and has employed the use of decisional Diffie–Hellman (DDH) assumptions, which according to the network would enable it to run a trustless operation.

“Lelantus pushes the boundaries of privacy with powerful technology that offers very high practical anonymity while requiring no trusted setup, and an elegant cryptographic construction that uses only well-established cryptographic assumptions,” said Reuben Yap, project steward of Zcoin. “Private crypto transactions live today either suffered from low privacy via small anonymity sets or required a degree of trust, something that is against the philosophy of public blockchains. Zcoin addresses both these issues. Our aim with Lelantus is to offer long-lasting privacy even in the face of increasingly advanced blockchain analysis techniques without compromising on trustlessness.”

Lelantus markedly improves on the original Zerocoin protocol’s performance, while enabling a key feature for anonymous transactions: confidentially transferring arbitrary amounts. Unlike Zcash, which is based on zkSNARKS, Lelantus requires no trusted setup. Lelantus is the trailblazer for other one-out-of-many proofs schemes that came after. This advanced cryptographic approach is already being considered by the likes of Monero, whose proposed Triptych protocol update would leverage many of the elements in Lelantus, including trustless set-up and obscured transactions.

Zcoin worked with ABDK Consulting to audit the Lelantus cryptography and Trail of Bits to audit the Lelantus cryptographic library.
