Thunderbolt network is an off-chain solution for large-scale sex transactions based on ethereum smart contracts. It supports all transactions that comply with ethereum'S ERC20 standard token, which is similar to the Lightning network, with instant to account, low transfer fees, scalability, and privacy protection. Participants using the Thunder network do not need to confirm transactions through the Ethereum main chain when they transfer money to each other, but instead create payment channels between participants to complete transactions off the chain.

RDN is a universal, decentralized cryptocurrency that will be used on the Raiden network to create payment channels and make payments through those channels. Raiden is a payment network built on top of the Ethereum network. The goal of the Raiden project was to provide an offline, easy-to-use channel network (that is, not on Ethereme's blockchain) without the need for mutual trust.

It works like the bar TAB in that you only pay the total to the bar when completed during the day, rather than going through the entire payment process every time you buy a drink. Each "bar TAB" is called a channel.

By using a decoupling payment channel instead of clearing blocks for each transaction, parties in the channel can send money or exchange tokens back and forth immediately, in large quantities and without cost, until netting in the Ethereum block chain decides to close the channel for the parties.

Any particular channel is one-to-one (e.g., Xiao Hong to Xiao Ming) and channels can be linked together to form a network, so users can pay anyone in the network. Since only two participants can get deposits in smart contracts for payment channels, payment channel transfers are not affected by double-flower attacks, making them as secure as on-chain transactions.
