Trasactions with "sequence":0

[ByteCoin]

If you view the last transaction in block 110300 you can see it has a line saying "sequence":0

This is also true for the last transaction in block 112696, for two transactions near the end of 113341 and the last three in 113599 but for no more to date (block 129000ish)

Does anyone know what was going on? I presume someone was testing a non-standard client.

Sequence numbers aren't very useful today because tx replacement is disabled. Nothing stops you setting a non-MAX_INT sequence number if you like though. It's probably indeed a separate implementation that isn't quite following the standard behavior.
