# 2.10 Multichain Model

With Armonia's layer-0 and layer-1 template software and SDK modules, users can rapidly build many versatile child chains with their uniqueness in consensus algorithm, block interval, virtual machine and finality choices, etc., to meet the various needs of the ecosystem.

`ACC` use have their own native tokens or directly utilize `$AMAX` which can be bridged from the `AMC` chain. It is highly encouraged to implement `ACC` that runs on a gas model and utilizes `$AMAX` for gas or transaction fee payment. By increasing the demand of $AMAX, `ACC` will help to add value to `AMC`, and even the entire ecosystem.

Basically, every single blockchain can be highly abstracted or characterized as the capital letter "T" whereby the horizontal line stands for all transaction and block data broadcasted throughout the network and the vertical line represents the state database (for example, account balance state) that is only constructed after execution of transactions produced from the horizontal line. Furthermore, a dotted line circle is used to represent an open and public blockchain network while a solid line circle represents a private blockchain. `AMC` can serve as trust anchor to all other `ACC` chains which collectively form the following multichain universe:
