The Swiss researcher Ethereum Arthur Gervais presented a demo version of the Liquidity Network project. It will allow Ethereum-purses to introduce and use an off-chain transaction protocol for payment channels, an analog of the Lighting Network for the bitcoin network.
For users, the process of transferring funds will not visually change. But under the hood of the Ethereum wallets, the off-chain protocol will connect the sender and the recipient through "hubs", which will provide payment channels between all connected to the "hub" parties.
During the demonstration of the demo version, Gervais showed the process of depositing funds for the "hub", and also transferred two users 50 Wei and 30 Wei (fractional shares Ethereum), respectively.
Earlier developers of the decentralized crypto exchange Altcoin Exchange conducted the first atomic transaction between the networks of bitcoin and Ethereum.
