+# How it works
16
+
17
+Transactions on the ripple blockchain are allowed to carry up to 1kB of arbitrary data via the memo field. 
18
+We can use this to store data of any size by building a tree of references between these transactions that can then be reassembled by reading them back from the blockchain.
19
+In order to generate these transactions xrpio sends payments with the minimum denomination between two wallets controlled by the user. 
20
+
21
+xrpio automatically takes care of the logistics behind this technique as well as compression of the data.
22
+
23
+Highly simplified, you can visualize the process like this:

+
27
+In practice each node does of course store significantly more data.
