Question about interpreting blockchain.info API return

Question

When looking at e.g. this output, for the "input" entry in first transaction in the block (i.e. always consist of newly generated coins): "inputs":[{"sequence":4294967295,"witness":"01200000000000000000000000000000000000000000000000000000000000000000","script":"03046a0a046b03966062696e616e63652f626afabe6d6d5eab0f9044182c948a6cc6c4cfcc4c8df66f5839f34cbf36afff532d3eb0188e020000001e34c5f04e198bb203b9000000000000","index":0,"prev_out":{"tx_index":0,"value":0,"n":4294967295,"type":0,"spent":true,"script":"","spending_outpoints":[{"tx_index":6620159290300855,"n":0}]}}]

I wonder what does it mean by "value":0,"n":4294967295. I tried to look up here in page for the number 4294967295 and found nothing. Also I suspect that the values for "value" and "n" seem to be reversed.

Answer 1

This is the same transaction using Blockstream.info API, that shows is a Coinbase Tx, in my opinion a much clearer output than blockchain.info. As per Bitcoin Wiki the sequence number is typically set to 0xFFFFFFFF (decimal: 4294967295), unless transaction's lock_time is > 0.
