how to recover from sidechain - aionnetwork/aion GitHub Wiki

v0.1.14 enforced the total difficulty check. if the block found by node , the total diff is less than the main net, the new block propagation will be rejected.

Steps to identify if node are in sidechain.

turn on p2p "show-log" in config.xml
<p2p>
		<ip>127.0.0.1</ip>
		<port>30303</port>
		<discover>true</discover>
		<show-log>true</show-log>
		<show-status>true</show-status>
</p2p>


find "p2p-status" section inside log file.


find your node id in p2p-status.

compare your block number and total diff with all other nodes.
if your block number >= others but total diff < other's total diff, you are in side chain.

Steps to recover.

revert your db to most reasonable block number.
./aion.sh -r "your_block_number_when_forked"

restart kernel to check "p2p-status" again to confirm your db back to main chain.
