Grin will undergo a network upgrade on January 16, 2021 at about 00:00 UTC.

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

1. Once the network upgrade is complete, mining Grin-29 will no longer be supported at f2pool. You will still be able to check your mining revenue for Grin-29 until March 15, 2021. If you have an unpaid balance, please apply for a payout to support@f2pool.com or open a support ticket.

2. Due to the transaction code upgrade component of the hard fork, we will temporarily pause Grin payouts as the upgrade is underway, including payouts of Grin-29 and Grin-32. When the upgrade is complete and the chain stabilizes, we will resume payouts. Please watch this announcement page for any further updates.

Due to a decreased number of miners and low mining revenue, we have decided to close our AE mining pool and HDAC mining pool at 00:00 UTC on January 14, 2021. You will still be able to check your mining revenue for these coins using your address until March 15, 2021. If you have an unpaid balance, please apply for a payout to support@f2pool.com or open a support ticket.

Due to an abnormality in the AE network, we have executed an emergency suspension of our AE pool and payouts. You cannot mine AE until the pool is back online, and may choose to switch to mine other cryptocurrencies that are available to minimize losses.

We are currently upgrading our AE pool to deliver a solution which was provided by the official AE team. All payouts will be made when the AE pool is restored. Keep a close eye on our announcement pages for the further updates.

On January 5, we distributed CFX rewards from the 30% off Conflux pool mining fees in December to the top 50 miners by daily average hashrate during the period of November 5 through November 30. Your rewards will show up in your account marked as “Activity Rewards.” Your balance will be paid out to you when it reaches the minimum threshold of 10 CFX.

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.

The IMG network is now returned to normal and f2pool’s IMG pool has already resumed. If you encounter any issue while you are reconnecting your miner, please contact our support team at support@f2pool.com or open a support ticket. Happy mining!

To better serve our miners, we will be upgrading our BTC pool server today at 11:00 UTC. It will take approximately one hour to complete the upgrade. Please monitor your miners during the upgrade process.

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

The Conflux (CFX) network will perform the Tanzanite network upgrade at block 3,615,000, which will be mined on December 11, 2020. The block reward for CFX will be reduced from 7 CFX to 2 CFX.

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

To better serve our miners, we will be upgrading our SERO pool server today at 08:00 UTC. It will take approximately three minutes to complete the upgrade. Your miners may go on and offline during the upgrade, so we recommend mining another currency until the upgrade is complete.

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

Due to an abnormality in the IMG network, we have executed an emergency suspension of our IMG pool. If you are mining IMG, please switch to DASH or another cryptocurrency that uses the same algorithm as soon as possible to avoid losses.

IMG payouts will be temporarily suspended. We will restore the IMG pool and make all payouts after the IMG network returns to a stable condition.

Today, December 8, we distributed PMEER rewards from the 120% bonus program that took place from November 30 to December 4. Your rewards will show up in your account marked “Activity Rewards.” Your balance will be paid out to you when it reaches the minimum threshold of 10 PMEER.

According to a recent official announcement from Zcoin, the development team has changed the Zcoin name to Firo and its ticker from XZC to XFR. We have updated our Zcoin web and app pages, mining tutorial, and other resources to reflect this change.

We are excited to inform you that f2pool now supports mining on the Qitmeer Medina Network, the infrastructure of a new payment network based on BlockDAG. PMEER is the token on the Qitmeer Medina Network, which is a new phase of Qitmeer’s testnet. Upon launch, these testnet coins will be mapped to become part of Qitmeer mainnet coins.

We support the PPS payout scheme, which facilitates higher and more stable rewards. From November 30, 2020 to December 4, 2020, you will receive an extra 20% bonus for each PMEER block mined.

The PMEER mining algorithm is Keccak256, which supports FPGA mining. Read our PMEER mining guide for more detailed information. Happy mining with f2pool!

The total block reward for ZEN will be halved from 12.5 ZEN to 6.25 ZEN when the block height reaches 840,000, which is estimated to happen on December 2, 2020 UTC. The portion of the ZEN block reward miners receive will be halved from 7.5 ZEN to 3.75 ZEN.

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

The ETC (Ethereum Classic) network will perform the Thanos hard fork at block 11,700,000, which will be mined on about November 29, 2020. The mining algorithm of ETC will change from Ethash to Etchash, which means Ethash ASICs and rented Ethash hashpower from NiceHash will not be able to process the new algorithm and mine ETC. Meanwhile, the ETC network’s DAG file will decrease in size. With this decrease, 3GB and 4GB GPUs will be able to continue mining ETC.

After the hard fork, you will need to update your configuration and restart your mining machines.

In our earlier announcement, “Our handling of the BCH hard fork upgrade”, we notified miners that BCHA (Bitcoin Cash ABC) would be distributed at a ratio of 1:1 based on BCH balances on November 15, 2020 at 12:00 UTC.

On November 26, 2020, we converted BCHA to BCH based on the price at 4:00 UTC and distributed it to miners. This BCH will show up on your revenue records with the label “Candy Distribution.” When your BCH balance reaches the minimum threshold, it will be paid out along with your BCH mining revenue.

Due to a decreased number of miners and low mining revenue, we closed our UFO mining pool at 00:00 UTC on November 20, 2020. If you have an unpaid balance, please send a withdrawal request to support@f2pool.com or open a support ticket.

The total block reward for ZEC will be halved from 6.25 ZEC to 3.125 ZEC when the block height reaches 1,046,400, which is estimated to happen on November 18, 2020 UTC. The portion of the ZEC block reward miners receive will be halved from 5 ZEC to 2.5 ZEC.

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

Since 18:00 UTC on November 15, some users have been experiencing an issue with the hashrate information displayed on the f2pool website and app due to abnormal synchronization of data with the cloud server. We are in the process of fixing bugs related to displaying the worker list and hashrate data. The correct historical hashrate chart will be restored no later than 04:00 UTC on November 17.

This issue only impacts the display of the data. Mining and payouts continue to operate normally and have not been affected by this bug. We apologize for any inconvenience caused by this display issue, but please be assured our team is working on deploying a fix.

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

We are happy to inform you that the loss compensation for the short disruption of our BTC and ETH pools on November 12, 2020 UTC was completed today. Affected users are able to see a record of their compensation on their payout history page.

Due to a network maintenance event completed by our regional internet service provider in Xinjiang and surrounding areas, we experienced some technical issues with some of our BTC and ETH pool services that were affected and began operating abnormally during 20:40-21:30 on November 12, 2020 UTC. Services resumed at 21:30 with an immediate fix and swift response from our team.

However, to cover losses of affected miners during this short disruption, we will recalculate revenues and send compensation as soon as possible. There will be further announcements with details regarding this payout, please stay tuned.

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!

We support the PPS payout scheme, which can facilitate higher and more stable rewards. From November 5-30, the top 50 miners by daily average hashrate will be offered 30% off on Conflux pool mining fees in December!

Conflux Network combines Proof of Work and the Tree-Graph data structure to power a high-performance public chain. Its mining algorithm is Octopus, which is ASIC-resistant and supports GPU mining. Read our Conflux mining guide for more detailed information. Happy mining with f2pool!

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.

The mining revenues payments will be suspended, f2pool will restore the ETC pool and complete all the payments as soon as possible after the ETC network returns to normal.

Due to ETC network issues on 1st August, f2pool temporarily suspended the ETC mining pool.

All issues are now resolved and the ETC pool is now live from 2020-08-02.

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.

The mining revenues payments will be suspended, f2pool will restore the ETC pool and complete all the payments as soon as possible after the ETC network returns to normal.

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.

The GRIN hardfork has completed at block 786,240 at 2020-07-17 08:28 (UTC).

From this hard fork upgrade, the Grin-29 algorithm has been changed from Cuckaroom to Cuckarooz. Old versions of GRIN mining software are no longer supported. Miners need to update their mining software to the latest version. Please refer to the Grin Mining Guide.

Miners using full node wallets need to upgrade their wallets to version 4.0.0. Miners using an exchange (e.g. Gate, Bitforex, Kucoin) or a mobile wallet service (e.g. Vate wallet) do not need to do anything unless you are informed to take additional steps by your exchange or wallet service.

f2pool has closed TRB mining pool services as of July 16, 2020. If you have any unpaid balance, please wait for f2pool to launch the small amount withdrawal function (targeted for mid-August 2020) in order for you to withdraw any remaining TRB mining revenue.

The Verge (XVG) block halving will occur at block 4,200,000 on approximately 2020-07-12. The block reward will decrease from 400 XVG to 200 XVG.

Please take note and plan what you want to mine after the halving, as your mining revenue may be reduced.

The GRIN hard fork will occur at block 786,240 at approximately 2020-07-16 03:00 (UTC).

The mining algorithm will change from Cuckaroom29 to Cuckarooz29. After the hard fork, old versions of GRIN mining software will no longer work. Miners need to update their mining software to the latest version. Please refer to the Grin Mining Guide.

Miners using full node wallets need to upgrade their wallets to version 4.0.0. Miners using an exchange (e.g. Gate, Bitforex, Kucoin) or a mobile wallet service (e.g. Vate wallet) do not need to do anything unless you are informed to take additional steps by your exchange or wallet service.

The BEAM hard fork will occur at block 777777 on 2020-06-28 UTC. The mining algorithm will change from BeamHash II to BeamHash III after the hard fork, and many previous versions of mining software will no longer work.

To prevent any missed mining revenue, we strongly advise our miners to use mining software which will automatically switch the mining algorithm. Please read our Beam Mining Guide and configure algorithm auto-switch, so your mining machine can mine normally after the hard fork.
