Running a big GRIN-Infrastructure allowed us to setup some GRIN-Chain monitoring solutions.
In coordination with the Grin-Council, we setup a “Block-Reorg monitoring system” for all our productive Grin-nodes. This service is not yet public, as we didn’t have the resources to implement this into our public API.
Details of the REORGs
REORG (blockchain reorganization) : A built-in feature of the Grin network designed to deal with the issue of simultaneously mined blocks.
REORG attack : A blockchain reorganization attack occurs when miners collaborate to remove previously confirmed blocks from the blockchain.
Scope of the upcoming report:
We are keeping it technical , no speculations no assumptions, even we did get in contact with gate.io and 2Miners
This topic should be put very visible in the Grin newsletter and be broadcasted on Twitter together with the link to the 51% attack report. In that way much more donations will come in, further boosting security.
