Other technical points of Raiden Network

Content

Channel multiplexing. A --> B --> C --> D.
Timeout channel. Open a channel with a time limit.
In summary, the trading model of Raiden Network above applies to:
It is used for small transactions for both parties of a transaction with a higher value of a certain token.
The application transformation of the application scenario of the off-chain token to the physical exchange
We must admit that one point is: Raiden Network does play a role in accelerating transactions.

For the application of tokens for physical exchange under the chain, the following problems need to be solved:

The optimization of the mortgage mechanism allows users with 0 token holdings to participate.
There are restrictions on returns after physical transactions and on-chain settlement to ensure that users will not initiate returns after clearing.
When the channel is established or closed, the user as the initiator must include the experience problem of ETH as a handling fee.
Expansion of the deduction mechanism for token handling fees.

At this point, the complete implementation of Raiden Network should include two core parts, namely: on-chain smart contract + off-chain relay server. If you want to implement an open source project based on the technical ideas of Raiden Networks at a certain time for the off-chain exchange of physical application solutions for contract tokens.
