I am going to make this nice and clear.
Nodes prune.
Any old transaction, any old data, anything that has been spent can be pruned.Equally, this does not mean that nodes need to prune. However, you cannot guarantee that your data will not be pruned. Nodes (note, nodes are exclusively miners) have the option of keeping or removing data at will. There is a section in my White Paper if you don’t understand this.
Equally, nodes can maintain a complete copy if they so choose. They can equally require payment for access. There is no requirement to distribute the entire Blockchain. In section 7 on page 4 of my White Paper, the reclaiming of disk space may be achieved by removing old spent transactions and even the branches. Block headers can be kept in memory and no more.
The development of overlay networks allows for the complete history to be maintained for limited subsets of the entire Blockchain. This will allow individual token issuers including some of the people on here to have a limited copy of the Blockchain that only serves their clients or people on their token system. Honestly, I really don’t understand why people think you need to validate everyone else’s transactions.
