Earlier this week Dash Core Group was made aware of claims that several Dash wallet addresses comprised around 51% of all Dash mining hashrates. We’ve spent the past few days to internally assess everything and better understand all addresses and hashrates involved. We’ve examined the claims and they appear correct at this time. However, we don't believe the entity in control of the wallets in question plans or wants to attack because their mining activities began at least 4 months ago and their blocks have been published for all to see. Additionally, since we were first made aware of these addresses, they have begun to remove their hashing power from NiceHash and diversify into various mining pools. This removes the risk of a malicious party renting the hashing power via NiceHash and simultaneously signals that the entity in control of the hashing power does not have negative intent. We believe the miner behind the hashing power was made aware by the same info we discovered online and quickly moved to more protected pools as they appear to be a major stakeholder of Dash. Graph shows Nicehash available hashrate for rent has decreased dramatically over the past day. Additionally, because of our unique InstantSend capabilities a transaction that was successfully locked via InstantSend would require a reorganization of over 24 blocks in order for a double-spend to succeed. There are many variables that have allowed this miner to amass this much hashing power, including newer ASICS on the market and the current price decline. At this time we do not believe there is reason for concern given our position as the largest X11 project in terms of hashing power (a 51% attack of this nature would make the attackers or NiceHash miners who rent their equipment obsolete and worthless). We also believe it is clear this entity has not shown malicious intent with their public activity. On a related note, Dash recently announced an innovation named ChainLocks that will make it even more difficult to perform a 51% percent attack on the Dash network since it would also require a 51% dominance of the masternode layer. ChainLocks will be included in a future update to the protocol. More details can be found here. We will be monitoring this situation closely and will publish more information if it becomes available or necessary. We encourage everyone with the ability to mine Dash to do exactly that and help distribute hashing power.
