Cosmos — SteemCN

Cosmos: (Interchain Foundation's crosschain open source project) focused on solving cross-chain asset transfer. The blockchain network is mainly composed of Zone and Hub.

The Cosmos Zone is a separate blockchain space.
The Cosmos Hub Center is a multi-asset equity certificate cryptocurrency network.

The Hub is a relay chain that is debited by a decentralized certifier group. A Hub communicates with multiple Zones. Each Hub has billing information for multiple associated Zones to generate a multiple asset center book. Hub guarantees asset transfer at different zones.

In the process, the total assets inside remain unchanged.

The Cosmos process is as follows:

First, the cross-link communication between Hub and Zone is achieved by the IBC protocol. Assume that Zone1 wants to perform cross-chain transactions with Zone2.

Zone1 generates and publishes transaction information on the Hub.
The Hub generates and publishes a proof of the presence of Zone1's cross-chain packets on Zone2.
Zone2 receives the message package and publishes the received certification information on the Hub.
The Hub gives proof that Zone2 has received the proof and sends the message on Zone2.

The advantages of Cosmos include the following:

The transfer of tokens in each Zone will be through the connected Hubs, so assets in each Zone will be recorded.
If a Zone fails, other valid Zones will not be affected.
The newly added Zone can easily be added to the Hub Center
