At the Conference Privacy Enhancing Technologies Symposium, held in Barcelona, Mobius technology was introduced, which hides information about Ethereum transactions and ensures their anonymity at the level of Monero. According to the authors of the project, due to the addition of additional tools to smart contracts, in addition to anonymity, the transaction speed increases (the transfer takes milliseconds), and the commission increases insignificantly (now it is about $ 0.06). The same technology adds anonymity to the work and to ERC20 tokens.
