Bitcoin ABC:0.14.6(EB8.0) is stuck at block 478558 (core, unlimited, btc1, uasf is at 478560) and logs:

Is not a issue, LOL

This is your "beautiful" scheduled fork.

[c0deright]

You're wrong.

core: blockhash(478558) = 0000000000000000011865af4122fe3b144e2cbeea86142e8ff2fb4107352d43
abc:  blockhash(478558) = 0000000000000000011865af4122fe3b144e2cbeea86142e8ff2fb4107352d43

so block 478558 is identical on ABC and core. but ABC doesn' accept the next block because of "prev block invalid".

So this clearly is a bug and not a fork.

[c0deright]

Have a look at https://www.btcforkmonitor.info/ where ABC is stuck at the same block.

The new block 478559 is not valid under ABC's new rules:
00000000000000000019f112ec0a9982926f1258cdcc558dd7c3b7e5dc7fa148 is marked invalid.
478558 (0000000000000000011865af4122fe3b144e2cbeea86142e8ff2fb4107352d43) is totaly fine.

Bitcoin ABC (Bitcoin Cash) Hard Fork: Activates when Median Time is Aug. 1, 2017, 12:20 p.m. UTC or later
block 478558: Current Median Time: Aug. 1, 2017, 12:37 p.m. UTC

@c0deright in what way is it a bug when this is the expected behavior? block 478559 is the first block that will be different and "mark the start of the new chain"

[c0deright]

Ok, my bad. Then i miscalculated the median time from which on ABC is rejecting blocks smaller than 1 MByte.

@c0deright We are forking. That's the whole point. Closing :)
