When there is a project that creates tokens, the project can choose to select an existing blockchain with mature protocol standards or re-develop a low-level protocol.
For example, in the “Square Ethernet” protocol, most of the market use “ERC-20” token, a token developed by “Square Ethernet” protocol, based on Public Square ether chain.
“ERC-20” protocol provides unified coding standards, including the underlying technology and charge transfer lifting between the underlying account codes, which makes use of “ERC-20” standard development that can be immediately compatible with the public Square Ethernet chain token, such that communication between other tokens are more efficient in different applications.
Based on this characteristic, using the same token, one sublayer protocol may use a uniformed charge for credit addresses. Unified charging currency accounts can easily address the unified management of different currencies, hence addressing that some of the cryptocurrencies have the same deposit address.
