Raiden testnet has been deployed!
Raiden benefits Ethereum:
1) Scalable: it scales linearly with the number of participants (1,000,000+ transfers per second possible)
2) Fast: Transfers are confirmed and final within the fraction of a second
3) Confidential: Single transfers don’t show up in the global shared ledger
4) Interoperable: Works with any token that follows Ethereum’s standardized token API
5) Low Fees: Transaction fees can be 7 orders of magnitude lower than on the blockchain
6) Micro-payments: Low transaction fees allow to efficiently transfer tiny values
