What's in a Bitcoin Cash transaction
Something we've always wanted to draw. How does a Bitcoin Cash transaction look like inside. Mostly useful for people going to develop and work on the protocol.
A note on
0 - Not locked < 500000000 - Block number at which this transaction is unlocked >= 500000000 - UNIX timestamp at which this transaction is unlocked If all transaction inputs have final (0xffffffff) sequence numbers then lock_time is irrelevant.
What is a "varint" - a compact representation of a number:
>= 0 && <= 252 1 byte: uint8_t >= 253 && <= 0xffff 3 bytes: 0xfd followed by the number as uint16_t >= 0x10000 && <= 0xffffffff 5 bytes: 0xfe followed by the number as uint32_t >= 0x100000000 && <= 0xffffffffffffffff 9 bytes: 0xff followed by the number as uint64_t
sha256 of the bytes making a transaction twice and then reverse the byte order. Source.
