I still do not understand what rayden is. Anyway, thanks for posting so I can deepen and study
Let me give out my view on what is Raiden Network based on my study!
First let us come to Raiden Network, Ethereum has been in the scalability issue for the past few months. Crypto currency payments are becoming common in today's technologically advanced world. Visa is processing the transactions at the rate of 50,000 per second,but when compared to Eth it can hardly process only 15 transactions per second on an average. Once more people start using crypto for payments, these need to compete with other fiat transactions. To solve this Raiden Network was introduced. In simple terms it is just a additional technology to Eth network. What does Raiden to do with transactions?
First, it increases the transaction speed to a very higher rate by doing around 100,000,000 transactions per second. Second, it can process private transactions by preventing the transactions to occur on-chain and most importantly a very cheap transaction on eth network. For the working of raiden, it is similar to the lightning network. Hence kindly refer to the working of lightning network by reading it's whitepaper.
Raiden Network is not only a technology, it is also a Cryptocurrency. Raiden Network Token (RDN) is an ERC-20 token which was created to fund the project and also to be used as a exchange medium in the network. Many people accept its token which has a minimal supply of 100 mill and currently 50% is in circulation and they can be traded in popular exchanges like Binance. This token has really good potential to make good returns once Raiden becomes popular.
