How do I get Bitcoin block header data with nonce?
There are tens of so called blockchain explorer websites, tens more offering on-line Bitcoin blockchain parsing.
But all I need are historic Bitcoin blockchain header data only for off-line mode study.
In theory I can set up blockchain parser on my own but I need to download full blockchain first and set up parser.
Since I live on wireless Internet 3G, it's not feasible to download 500GB data, so I would prefer an option just to buy historic Bitcoin blockchain header only data, no overheads, no transaction data.
If you know such place or can offer such download, let me know your terms.
