Coin Shuffling

Total transaction anonymity is not a feature of the Nxt blockchain system: every transaction can be seen and traced, giving an unprecedented level of transparency to the world of digital currencies.

However, some users would like to anonymise their funds or transactions: this anonymisation can be done using the Nxt Coin Shuffle system.

Coin Shuffling is an effective privacy feature: it enables users to mix their funds quickly and efficiently with other users’ funds by creating a random mapping between existing user accounts and new recipient accounts provided by the users.

The Nxt implementation is the first Shuffling system to be implemented on a decentralized blockchain, and was originally developed to be implemented in Bitcoin itself. The shuffling algorithm is based on a paper by Tim Ruffing et al. and the Nxt implementation of his work has been reviewed by Tim and his team.
