Configuration Set

The entire system is composed of multiple contracts, and contracts are connected through configuration groups.

The configuration group includes serial number contracts and configuration item contracts. The configuration group is equivalent to realizing a readable and writable storage space on Nervos.

All the data uses little-endian mode.

Serial Number Contract

It is similar to the self-incrementing ID of the database. Each time a new configuration item is created, the ID is automatically incremented by 1. And it is unique.

Its existence in Nervos is a special cell. Its data represents the current ID value.

The function of the contract is that when an update is required, the ID indicated by the data value must be +1 The corresponding code is:

Configuration Item Contract

A configuration item corresponds to a cell, the first 4 bytes of cell data represent the serial number, and the others are configuration values.

When the cell of the serial number contract is updated, a configuration item corresponding to the ID is created.

The configuration item can modify the configuration, but its serial number cannot be changed.

In order to retain the update capability, under normal circumstances, there will be 2 cells for configuration items with the same serial number. This can prevent other related transactions from failing during the update.

For example, there will be two cells for asset price information. If there is only one cell, when the price is updated, the pledge transaction will fail because it has not yet been chained.
