Almost all CPUs these days work natively in little-endian. To operate on big-endian numbers, additional byteswap instructions are needed. For most things, I think this effect is negligible. Network protocols need a convention to represent things, and Bitcoin's creator picked one. The actual choice barely matters.


They're exactly the same number; one is written in little endian notation and the other is big endian. Notice that the bytes (two-hex-digit pairs) are exactly reversed from one to the other. Block explorers like blockchain.info usually expect big-endian for block hashes. The proof-of-work requirement means that the most significant bits have to be zero, ...


tx_hash and tx_hash_big_endian are the transaction id of the transaction that this output originated from in little endian and big endian (reversed). tx_output_n is the number of the output in the referenced transaction, i.e if a transaction has 5 outputs and you need to refer to the 5th you use a tx_output_n = 5. tx_index I believe is an internal unique ...


The answer is simple: big-endian architectures are not supported.


I guess that the script is the owner's address.I am not sure about this. According to https://en.bitcoin.it/wiki/Script Bitcoin uses a scripting system for transactions. Forth-like, Script is simple, stack-based, and processed from left to right. It is intentionally not Turing-complete, with no loops. A script is essentially a list of instructions recorded ...


Displayed precision ≠ Stored precision Note that the block timestamp is stored as a 4-byte number of seconds since 1970-01-01T00:00 UTC (the Unix epoch). However Blockchain.com show this in a more human readable form rounded or truncated to the nearest minute (2011-05-21 18:26). So if you convert that human readable time back to an integer, you will get a ...


It is the same hash but reversed since bitcoin transmits data using little endian format (most significant byte last)
