Currently, the Ethereum network is limited to around 20 transactions per second. This is twice as much as Bitcoin can handle. However, if we are looking at a future where Ethereum is used as a daily form of payment, this isn’t enough.
The Raiden Network is aiming to solve this problem. Its developers are building an off-chain solution for Ethereum payments which scales linearly with the number of participants. The network could in the future handle over 1,000,000 transactions per second.
Additionally, it will allow decreasing transaction cost by seven orders of magnitude, making true micro-transactions on Ethereum a reality.
