I am just developing and testing Bitcoin mining application in plain Javascript (slow but can be run off-line).

To test it to work correctly I need to download Bitcoin block headers from Blockchain.info , 6 input parameters .

Are you aware how to call Blockchain API https://blockchain.info/api/blockchain_api

I don't use Bitcoin address, no other mining app, just need to download a number block headers from hashed blocks.

Any idea, demo, example or csv file coming with 6 input parameters as described in Bitcoin hashing algorithm

  • It might be easier to test (and more profitable to run) should you target an alt-coin rather than Bitcoin

You can download the blockchain headers using ElectrumX. The data is binary packed, but can be deserialized easily enough. You seem to be trying to solo mine, which is a bad idea at the best of times, let alone with JavaScript. You also seems to be trying to build a SPV client. An easier way would just be to use https://blockchain.info/latestblock to get the lastblock hash and use that.
