In Berlin the last test network of payment channels Raiden for Ethereum has been launched.
The release includes a minimal implementation of the scaling solution, which will allow the transfer of Ethereum tokens outside of the main blockchain. This is the last test phase before the introduction of technology into the core network of Ethereum.
Developers note that the technology represents an early implementation for the core network and contains a new rewritten code of smart contracts and payment channels that can be recovered in the inadvertent closure case
The release date for the main network has not been assigned yet. However, the developers intend to follow their earlier promise and launch Raiden this summer.
