The Ethereum network will perform an upgrade on block height 12,965,000, which is estimated to happen at about 12:00, August 5, 2021, UTC. We’ve upgraded our node and set up Flashbots MEV, as Ethereum miners with F2Pool you do not need to do anything specifically for the upgrade.

After the upgrade, the fixed block reward will remain the same, however, the gas fee structure will be adjusted to “BaseFee + Tips”. The BaseFee in each block will be burned and the Tips will still be a part of the miner’s income. Due to the fees burned, there will be possible decreases in fees. As fees are a result of network activity, this is usually hard to estimate since it’s subject to the actual gas fees mined.

The London upgrade will also push back the difficulty bomb to December 2021. Before the bomb is triggered, you may continue taking part in Ethereum mining.

If you have any questions, please contact our support team at support@f2pool.com or open a support ticket.

The Ethereum DAG file size is estimated to reach 4 GB on December 25, 2020 at 2:00 UTC. After that, mining Ethereum with 4GB GPUs or ASICs will be affected. Miners can refer to the following ways to deal with the change:

1. Use software like Bminer v16.4, lolMiner or Teamredminer. Both of these support continued mining of ETH with 4 GB memory devices but with some loss of hashrate, since every time the epoch file grows in a 4 - 5 day cycle, the hashrate will decrease slightly.

2. Modify your GPU’s onboard memory units. Find a reliable service provider to change the miner’s memory units to a higher capacity to continue mining ETH.

3. Switch to other networks with your current, unmodified hardware. 4 GB GPUs will continue work on mining other coins such as BEAM, RVN, SERO, and ETC. You may refer to the f2pool Popular Miners page to see revenue information on different networks.

The Claymore Ethereum v15.0 miner will no longer support mining when the DAG epoch reaches 384. Unless an updated version of Claymore is released to address this issue, miners may need to switch to other mining software to avoid losses.

BCH (Bitcoin Cash) will undergo a network upgrade on November 15, 2020 at about 12:00 UTC. The upgrade may result in two different chains and additional tokens due to the differences of opinion between two main BCH clients, Bitcoin Cash ABC (BCHA) and Bitcoin Cash Node (BCHN).

We will take the following steps to ensure the security of our users’ assets:

1. When the upgrade completes, our BCH pool will be transitioned to a BCHN pool.

2. Starting from 23:40 UTC on November 14, 2020, BCH mining as part of the BTC Profit-Switching (SHA256d) pool will be suspended. BSV and BTC mining will remain available.

3. Due to the lack of transaction replay protection and the risk of on-chain transactions during the upgrade, BCH payouts will be paused from November 15 on.

4. If the upgrade results in additional tokens, we will credit them at a ratio of 1:1 based on BCH balances on November 15, 2020 at 12:00 UTC.

5. When the upgrade completes and the chains stabilize, we will release further announcements about when we will resume payouts and BCH mining in the BTC Profit-Switching (SHA256d) pool, our support for BCHA mining, the distribution of new tokens, etc.

The Grin network was hit by a 51% attack from 01:10 to 02:47 on October 8, UTC time. Grin mining was affected but is now back to normal. We remind our miners to pay close attention to the Grin network and potential risks of continuing to mine Grin. You mine Grin at your own risk, and your mining rewards will be affected if further attacks take place. Therefore, please evaluate the risks and exercise caution when mining Grin.

We are excited to inform you that f2pool now supports mining on the Conflux Network!

As the size of the Ethereum blockchain continues to increase, ETH mining requires GPU cards with more memory to store DAG files. Starting from about October 17, 2020 UTC, it will no longer be possible to mine ETH with 4G GPU cards on Windows machines.

In order to continue mining with 4G GPU cards, please try one of the solutions below.

1. Switch to Linux or a dedicated mining operating system. ETH can be mined with 4G GPU cards using these operating systems until the end of December 2020.

2. Increase memory size to 8GB to avoid future problems caused by the increasing size of the DAG file.

3. Start mining other coins, such as BEAM, RVN, SERO, etc. You can check the daily revenue of these coins here before making a decision.

f2pool has reduced the default fee of ETH pool for 20%, from 2.5% PPS+ to 2% PPS+ as from today. Start mining with f2pool and get the benefit!

OKEx suspended withdrawals today. If you are an OKEx user, please follow the exchange’s announcements and set a new f2pool payout address to make sure you receive your payouts on time.

Due to a decreased number of miners and low mining revenue, we have decided to close our BFC, PASC, LUX, and SCC mining pools at 00:00 UTC on September 23, 2020.

You will be able to check your mining revenue for these coins using your address until November 22. If you have an unpaid balance, please apply for a payout to support@f2pool.com or open a support ticket.

We will be upgrading the f2pool.com website from 07:00 to 09:00 UTC on September 22, 2020. During the upgrade, some account-related functions will be unavailable, including registering, adding, and deleting subaccounts, changing your payout address, changing your payout threshold, and pausing payouts. Your ability to view your account information will be unaffected.

The total block reward for CLO will be reduced from 216 CLO to 129 CLO on September 20, 2020. The portion of the block reward miners receive will be reduced from 129.6 CLO to 71.28 CLO.

Please consider this when planning your mining activities, as your revenue from mining CLO may be reduced.

The total block reward for XZC will be reduced from 25 XZC to 12.5 XZC on September 15, 2020. The portion of the block reward miners receive will be reduced from 14 XZC to 6.25 XZC.

Please take this into consideration when planning your mining activities, as your revenue from mining XZC may be reduced.

The block reward for Monacoin (MONA) will be halved from 25 MONA to 12.5 MONA on September 8, 2020.

Please take this into consideration when planning your mining activities, as your revenue from mining MONA may be reduced.

The number of confirmations required by some third-party wallets and exchanges has increased. Miners should contact the platforms where they receive ETC payouts to confirm the exact number of confirmations required by their platform.

While our payout system has not changed, it may take longer than usual for you to receive your ETC payouts due to this change.

We have made an optimization for checking mining revenue. “24 Hours Revenue” has been replaced with “Yesterday’s Revenue” to make the process more convenient.

In f2pool’s previous revenue data, “24 Hours Revenue” was defined as your revenue from 24 hours previous up to the time you checked the data. Our users often mistook it for the previous day’s revenue.

After collecting opinions from miners, we removed “24 Hours Revenue” from our revenue data and replaced it with “Yesterday’s Revenue” to increase the accuracy and effectiveness of the data. Now, “Yesterday’s Revenue” stands for the previous day’s revenue, on a settlement day (payouts circle) basis.

Due to the recent hard fork on the VCASH network, we needed to upgrade our wallet to execute payouts normally. The upgrade is now complete, and we have resumed VCASH payouts.

Due to a decreased number of miners and low mining revenue, we have decided to close the ETP pool at 00:00 UTC on August 27, 2020.

The ability to check ETP mining revenue using your address will be retained for two months. If you have an unpaid balance, please wait for us to launch a small amount withdrawal function (expected in mid-September) and try to withdraw to your wallet yourself, or apply for a small amount payout via a support ticket/email.

We had an abnormality in our ETH pool during an upgrade from 9:30 to 11:00 UTC on August 16, 2020. Some ETH miners who were mining with a username encountered hashrate declines or disconnections.

To recover losses, we have decided to recalculate the revenue of the affected miners in terms of their actual hashrate during this period and make compensation. The relevant data has been collected, recalculation has been completed, and the compensation will be distributed into affected accounts on August 20, 2020 UTC.

Thank you for your continued support and understanding. We continue to provide a reliable mining pool service.

In accordance with its protocol, Grin no longer supports the C31 mining algorithm. Corresponding shares of block outputs of C31 became 0 when the block height reached 826,560 at 03:59:08 on August 14, 2020 UTC. Grin supports multiple mining algorithms, and each algorithm’s share of block output continues to change.

Miners should switch to Grin’s C29 or C32 mining algorithms or to other coins that are more profitable to mine to avoid potential losses.

On August 13, 2020, VCASH network’s hard fork was completed. Because we need to upgrade our wallet to process transactions normally, VCASH payouts have been temporarily suspended.

We will be making a separate announcement once we have finished the upgrade and VCASH payouts are re-enabled. Please stay tuned!

Due to ETC network issues on 6th August 2020, f2pool temporarily suspended the ETC mining pool.

All issues are now resolved and the ETC pool is now live from 2020-08-10.

Due to the abnormality of the ETC network, f2pool’s ETC node has been affected, and we have urgently suspended the ETC pool. ETC miners please switch to other cryptocurrencies for mining as soon as possible to avoid loss.

From 2020-08-01, f2pool will support the PPS+ payment method for ETH wallet address mining. Miners who use a wallet address to mine ETH will now also get a share of the mining fee, as a bonus.

PPS+ is a combination of two models, PPS and PPLNS. The block reward is settled according to PPS, and the transaction fee is settled according to the PPLNS model. It means that with PPS+, the miner obtains additional income from a portion of the transaction fee based on PPLNS.

For coins that have growing transaction fees, adopting the PPS+ method helps miners increase their revenue.

Some 4 GB GPU mining cards have encountered issues, including lower than expected hashrate, errors in the mining software and disconnections while mining ETH.

As the ETH Epoch continues to increase, ETH mining requires GPU cards with a larger memory space to store DAG files. Claymore’s latest version is no longer able to support ETH mining on 4 GB GPU cards anymore. This has caused some miners using Claymore and 4 GB GPU cards to have issues mining ETH.

In response to this problem, many mining software providers have provided solutions:

Bminer and PhoenixMiner have already optimized their mining software and miners can continue mining ETH on 4 GB GPU cards using the latest version of Bminer and PhoenixMiner.

f2pool will close DERO mining pool services as of July 24, 2020 00:00 UTC.

If you have any unpaid balance after this date, please wait for f2pool to launch the small amount withdrawal function (targeted for mid-August 2020) in order for you to withdraw any remaining DERO mining revenue.
