Why did MineXMR shut down?
MineXMR shut down on August 12, 2022, after its operators announced that they were closing the Monero mining pool. They did not give a detailed public reason, so it would be misleading to say the shutdown was definitely caused by a hack, a ban, or concerns about the pool becoming too large.
What the operators actually announced
MineXMR was a mining pool: a service that combined many miners’ computing power so they could earn smaller, more regular payments instead of waiting to find a block alone. A block is a batch of transactions added to Monero’s transaction record.
The closure announcement told miners to move to another pool before the shutdown date. It also recommended P2Pool, a system that lets miners share rewards without relying on one central pool operator.
That recommendation matters, but it is not a full explanation of the decision. The public announcement established that the operators were ending the service. It did not establish their personal, financial, or business reasons.
Why people connect it to centralization
MineXMR had become one of Monero’s largest pools. Earlier in 2022, estimates showed it briefly reaching or exceeding half of the network’s mining power. That raised serious concerns in the Monero community.
Mining power, also called hashrate, is the rate at which computers perform the calculations used to mine. When too much of it is directed through one pool, that pool’s operator gains too much influence over which blocks get produced.
A pool controlling a majority of mining power could potentially attempt a 51% attack. That means using its advantage to interfere with transaction ordering, block certain transactions, or reverse some of its own recent payments.
It would not let the operator take coins from arbitrary wallets or create unlimited XMR. Still, the risk was enough for community members to urge miners to leave MineXMR for smaller pools.
Was that definitely why it closed?
No confirmed public explanation establishes that connection. You should separate three things:
- Confirmed: MineXMR announced its closure and stopped operating.
- Relevant context: Its size had prompted concerns about Monero’s mining power becoming concentrated.
- Unconfirmed conclusion: The operators closed specifically because of those concerns.
Recommending P2Pool was consistent with spreading mining power more widely. But that alone does not prove why the operators decided to shut down.
Likewise, you should not treat the closure as evidence that Monero mining had ended or that the Monero network had failed. MineXMR was one service within the network, not the network itself.
What the shutdown meant for miners
If you were using MineXMR, you needed to redirect your mining software to another working pool. The announcement also said pending rewards would be paid after the shutdown, so the announced closure was not simply an unexplained disappearance with miners’ balances.
Today, an old guide that tells you to connect to MineXMR is outdated. Be cautious if someone offers to “reactivate” your MineXMR account or recover old rewards for an upfront fee. Never share your wallet’s recovery words, which give someone control over your funds.
The bottom line
MineXMR closed because its operators chose to discontinue the service; their detailed reasons were not publicly explained. Its unusually large share of Monero mining power is important background, but presenting centralization concerns as the proven cause goes beyond what was announced.
