Raiden is a technology that leverages off-chain state networks to extend Ethereum with some nice properties for asset transfers:
it scales linearly with the number of participants (1,000,000+ transfers per second possible)
Transfers are confirmed and final within the fraction of a second
Single transfers don’t show up in the global shared ledger
Works with any token that follows Ethereum’s standardized token API.
Transaction fees can be 7 orders of magnitude lower than on the blockchain
Low transaction fees allow to efficiently transfer tiny values.
