SomberNight	d7c5949365	prefer int.from_bytes over int('0x'+hex, 16)	2018-11-26 01:16:26 +01:00
SomberNight	a8e6eaa247	blockchain: fix difficulty retarget ... "target" is a 256 bit int, but the "bits" field in the block headers that is used to represent target is only 32 bits. We were checking PoW against the untruncated target value, which is a slightly larger value than the one that can actually be represented, and hence we would have accepted a slightly lower difficulty chain than what the consensus requires.	2018-11-22 16:52:51 +01:00

SomberNight	37206ec08e	network: auto-switch servers to preferred fork (or longest chain) ... If auto_connect is enabled, allow jumping between forks too. (Previously auto_connect was only switching servers on a given fork, not across forks) If there is a preferred fork set, jump to that (and stay); if there isn't, always jump to the longest fork.	2018-10-11 20:07:19 +02:00
