The model that describes how data is written to a blockchain is the: append-only data structure.
<h3>What is an Append-only Data Structure?</h3>
Append-only is computer data storage property whereby new data can be added to a blockchain, like an additional block, in a time-ordered sequential order in such a way that the data added cannot be easily altered as al data are permanently stored across all nodes.
The append-only data structure makes data stored almost immutable. This is the model in which the blockchain technology is built on.
Therefore, the model that describes how data is written to a blockchain is the: append-only data structure.
