Users SBAT use fast sync with IBFT #281

Closed asaj closed 5 years ago

asaj commented 5 years ago

Expected Behavior

Fast mode sync should work in IBFT

Current Behavior

Fast mode sync is broken in IBFT. All other sync modes - full, light, and celolatest work. fast sync mode never works. I am unsure if clique network works or not since I cannot connect to our argentinaproduction network with the new version of geth.

This is the error I see, syncing is happening but for some reason, all the received blocks are being rolled back.

Tested using geth_tests/integration_network_sync_test.sh integration fast taken from https://github.com/celo-org/celo-monorepo/pull/3516
