Registers

A register is a general CRDT mutable data type that holds a value. Registers are used to store appendable data—data can be added to a register with previous values still being accessible.

Autonomi deploys a special type of register called a Merkle register which supports concurrent writes. If two actors write to a register at the same time a fork will be created with both versions kept available. It's then up to client software to decide which fork to choose, according to the app's own rules.
