    Raiden Network

    Raiden Network

    Raiden Network

    The Raiden Network is an off-chain scaling solution, enabling near-instant, low-fee and scalable payments. It’s complementary to the Ethereum blockchain and works with any ERC20 compatible token. The Raiden project is work in progress. Its goal is to research state channel technology, define protocols and develop reference implementations. The Raiden Network is an infrastructure layer on top of the Ethereum blockchain. While the basic idea is simple, the underlying protocol is quite complex and the implementation non-trivial. Nonetheless the technicalities can be abstracted away, such that developers can interface with a rather simple API to build scalable decentralized applications based on the Raiden Network. The basic idea of the Raiden Network is to avoid the blockchain consensus bottleneck. This is done by leveraging a network of payment channels which allow to securely transfer value off-chain, i.e without involving the blockchain for every transfer.
