Have an effect on: Top

Factor description: State database consensus factor in geth with deletion of account information, which might occur right through SUICIDE directions.

Affected implementations: All geth implementations as much as and together with variations 1.0.1, 1.1.0 and broaden (“risky 1.1.0”) had been affected. Eth (C++) and pyethereum (Python) are unaffected.

Proposed brief workaround: Miners transfer to eth or pyethereum asap

  • 21/08/15 11:30+2:00 Because the prevalence of the consensus factor, we now have been intently tracking the chain and community. Consistent with community statistics, maximum miners have upgraded to the patched 1.0.2 or switched to eth. Our expectancies regarding most most probably chain-reorganization intensity is 750 blocks.
