Massive mainnet reorganizations of the Ethereum Classic chain after Phoenix hard fork #11744

Closed q9f closed 4 years ago

q9f commented 4 years ago

Screenshot at 2020-06-01 13-31-19

We keep seeing long reorgs on the Ethereum Classic mainnet with the Open Ethereum client only, some are 50 - 90 blocks long. Other clients are not affected.

It's not Ethereum Classic that reorganizes but the Open Ethereum client. The title might be misleading as other clients are not reorganizing.

sorpaas commented 4 years ago

I checked ETC folks' discussions at their Discord, Besu is also suffering some issues after Phoenix hard fork. So looks like the only implementations not affected are Geth-family ones.

@q9f

It's not Ethereum Classic that reorganizes but the Open Ethereum client. Your title is mildly misleading as other clients are not reorganizing.

We welcome discussions here, but please stop provoking others.
