May 2023 Work Progress Report: Kaspa and Cortex Block Reward Reduction
June 1, 2023
Planned block reward reduction for Kaspa and Cortex blockchains, multiple node updates.
Kaspa Reward Reduction
In line with the planned Kaspa emission schedule, a significant event took place on May 8, impacting the mining community associated with Kaspa. The block reward for mining was decreased from 233 KAS to 220 KAS. This change reflects the Kaspa monetary policy’s Chromatic Phase, which involves geometrically decreasing block rewards over time.
It’s crucial to note that such reductions are part of Kaspa’s unique monetary policy, designed to ensure a fair distribution of KAS and the long-term sustainability of the network. These changes are integral to the network’s progression and adherence to its predetermined roadmap. At 2Miners, we remain committed to supporting miners through these adjustments, providing an efficient and profitable mining environment. As always, we recommend miners stay informed about such changes, which can be followed via the Kaspa Emission Schedule.
Cortex Reward Reduction
The Cortex (CTXC) blockchain underwent its halving event on May 2nd. As a result of this crucial adjustment in the network’s monetary policy, the block reward for miners was slashed from 7 CTXC to 3.5 CTXC per block. This halving process, inherent to the Cortex protocol, effectively diminishes the mining reward by 50%, thereby impacting the rate at which new CTXC tokens are created and injected into the market.
For the miners on the 2Miners pool, this implies a reduction in the amount of CTXC tokens they earn for their computational contributions. Nevertheless, while the miners’ immediate income may be lessened, such halving events historically tend to induce a scarcity effect, potentially driving up the value of the cryptocurrency over time. Thus, the impact of this event on the long-term profitability of mining Cortex remains to be seen.
Mining Pool Updates
We conducted several key updates to the cryptocurrency nodes on the 2Miners mining pool, ensuring the smooth operation and enhanced security for our miners. The updated nodes are as follows:
Zcash (ZEC) updated to 5.5.1
Horizen (ZEN) updated to 4.0.0
Monero (XMR) updated to 0.18.2.2
Beam updated to 7.3.14073
Let’s look closer at each of these updates:
Zcash (ZEC) 5.5.1 Update: This upgrade addressed an issue that could cause a node to crash when the privacy policy did not include ‘AllowRevealedRecipients’ while creating a transaction resulting in transparent change. Additionally, it corrects an underestimation of the ZIP 317 conventional fee when spending UTXOs, preventing delays or blocks in mining transactions.
Horizen (ZEN) 4.0.0 Update: This major update includes new key features and introduces a hard fork. It supports V2 sidechains and sets the upcoming deprecation date. Key enhancements include non-ceasable Sidechains and Key Rotation, making the verification process more flexible without compromising security. This release marked the end of supporting Ubuntu Bionic, limiting future releases to Ubuntu Focal or newer.
Monero (XMR) 0.18.2.2 Update: The ‘Fluorine Fermi’ release introduced several improvements such as adding a size limit for tx_extra in the transaction pool, avoiding log entries when re-blocking a subnet, and fixing an infinite loop in fake out selection. This update also enhanced the security by adding Ledger Stax support.
Beam 7.3.14073 Update: This hotfix addressed a crucial bug that led to the creation of invalid blocks, temporarily halting the generation of new blocks. It optimized block creation and listed some known limitations, such as not going offline for over 24 hours when using active laser beam channels and not offering the same offline address to multiple senders of payments.
Each of these updates is part of our continued commitment to maintaining the 2Miners pool at the forefront of technological advancements, providing the best possible service for our mining community.

April 2023 Work Progress Report: New Coin – Kaspa, Ergo Block Reward Reduction
May 1, 2023
The new coin on 2Miners – Kaspa, planned block reward reduction for Ergo, share difficulty optimization for Monero, and pool node updates.
Kaspa on 2Miners
We are pleased to announce that 2Miners pool has expanded its mining offerings to include Kaspa (KAS), an innovative cryptocurrency with a focus on scalability, security, and decentralized governance. Recognizing the growing interest in Kaspa mining among our community, we have made it easy for both GPU and ASIC miners to join our pool and benefit from its features.
Kaspa mining on 2Miners is available for both SOLO and PPLNS mining options. We have set up dedicated ports for ASIC miners, with port 3434 for the SOLO pool and port 2222 for the PPLNS pool. These ports have been thoroughly tested and optimized to minimize the number of invalid shares for ASIC devices, ensuring a smooth mining experience. How to Mine Kaspa with ASIC and GPU: Settings, Extra Rewards, Dual Mining
2Miners is known for its commitment to fairness and transparency, and we continue to uphold these values with our Kaspa mining offerings. We are the only pool that pays out the full block reward, including the extra 233 KAS in case of retroactive block rewards. This means that miners receive the maximum possible payout for their mining efforts.
In less than a month more than 2000 miners joined our KAS pools with a total hashrate of almost 80 TH/s making 2Miners the Top-10 pool for Kaspa mining. We plan to add the BTC payouts option to our Kaspa pools in the nearest time. You could already get paid for ETC, ERGO, RVN, ZEC mining in BTC if you mine on 2Miners.
Ergo Block Reward Reduction
Ergo, a Proof of Work blockchain, follows a predetermined emission schedule for its native ERG tokens. In April, the block rewards decreased from 42 ERG to 39 ERG, in line with the planned schedule. To ensure the long-term sustainability of the mining protocol, the Ergo Foundation proposed EIP27, an amendment to the emission schedule.
EIP27, which received over 90% approval from the mining community, extends the emission schedule by approximately 17.38 years. This extension provides Ergo with more time to establish the necessary crypto-economic security for its blockchain, promoting continued growth and development.
Monero Share Difficulty Optimization
We have recently made improvements to our Monero mining pools, focusing on optimizing server performance. One of the key changes we implemented was increasing the share difficulty from 120K to 480K. This adjustment was made to enhance the efficiency of our servers, allowing them to better handle the growing number of miners. What is Share and the Share Difficulty When You Are Mining at the Pool?
It is important to note that the change in share difficulty does not impact the rewards received by miners. Share difficulty is a parameter that affects the amount of work required from miners to submit a valid share. By increasing the share difficulty, we reduce the number of submitted shares, which in turn reduces the load on our servers, leading to improved stability and performance for the mining pool.
Our goal with these updates is to provide a better mining experience for our users, ensuring that our mining pools are reliable and efficient.
Mining Pool Updates
Maintaining up-to-date cryptocurrency nodes in a mining pool is essential for various reasons. First and foremost, it guarantees the network’s security and stability, as updates frequently contain fixes and enhancements for safeguarding against potential threats. Second, it improves mining effectiveness and performance by integrating optimizations and modifications into the software. Lastly, keeping current with updates enables miners to adjust to shifts in consensus protocols and algorithms, ensuring compatibility and preventing potential income losses.
This month we updated the nodes for Monero and Cortex mining pools.
Monero v0.18.2.0-release Fluorine Fermi, Major Point Release 2. This is the v0.18.2.0 release of Monero software, which brings various bug fixes and improvements, particularly in block propagation time. Key highlights of this release include an added cache for a significant increase in block propagation speed, fixing ping issues to discover healthy peers for connection, updating OpenSSL to 1.1.1t, and many more minor bug fixes and improvements.
Cortex 1.10.41-stable-51b6aae2 includes the protocol upgrade & potential bugs fix. And at top of that, we installed the 1.10.42 version with a hotfix.

How to Mine Kaspa with ASIC and GPU: Settings, Extra Rewards, Dual Mining
April 14, 2023
This article delves into the world of Kaspa mining, exploring the techniques and hardware utilized for this innovative cryptocurrency. We will discuss the mining processes on both GPU and ASIC devices, highlighting the advantages and challenges associated with each method. Learn how Kaspa’s unique DAG structure impacts mining and uncover the potential rewards for participating in the mining process of this growing network.
Introduction to Kaspa Cryptocurrency
Kaspa is a unique hybrid cryptocurrency that combines features of both Bitcoin and Ethereum-like blockchains. Its primary innovation lies in its approach to organizing blocks, which relies on a Directed Acyclic Graph (DAG) structure instead of a linear chain. In Kaspa, multiple blocks can be generated simultaneously, allowing for faster transaction processing and higher throughput compared to traditional blockchains.
One of the key differences between Kaspa and other cryptocurrencies is its block generation rate. Kaspa aims to produce a new block every second, resulting in a much higher frequency of blocks compared to most other cryptocurrencies. This rapid block generation is enabled by the GHOSTDAG protocol, which helps maintain the consistency and security of the network despite its non-linear structure. Use Kaspa Visualizer to visually understand how is it done.
Kaspa’s block rewards are also unique, as they are paid retroactively to the addresses of the blocks being pointed to, rather than directly to the miner’s address. Additionally, when a block points to a “red” (poorly connected) block, the block reward goes to the miner instead. This incentivizes miners to merge poorly connected blocks, improving the overall connectivity of the network.
Furthermore, Kaspa employs a custom-built mining algorithm called KHeavyhash, which is designed for GPU mining, allowing for dual mining of Kaspa and other cryptocurrencies relying on memory-intensive mining algorithms. However, the recent introduction of ASIC devices in the network could impact the mining landscape and centralization risks.
Why Choose 2Miners Mining Pool for Kaspa
When it comes to mining Kaspa, selecting the right mining pool can significantly impact your overall mining experience and profitability. 2Miners mining pool is a top choice for Kaspa miners due to its numerous advantages, professional service, and commitment to transparency. By choosing 2Miners, you gain access to dedicated powerful servers, low latency internet connection, reliable connections to other nodes, and a hassle-free mining environment.
2Miners set the special port for ASIC devices. It ensures the best performance of your machines and reduces internet traffic significantly.
Mining with a Pool is More Secure
Kaspa features a very rapid block generation rate. A new block is created every 1 second on average. That means 86 400 blocks are created daily. Nearly all the miners, especially in the first days of Kaspa mining chose to mine alone using their own Kaspa cryptocurrency node. Thanks to the Kaspa developers that process is not much complicated. With the growth of the KAS network, many miners opted for the mining pools. 2Miners provides not only the collective PPLNS pool for Kaspa but also the SOLO pool. A PPLNS pool gives the possibility for the rig owners to team up and mine together. This helps to get much more stable rewards. And what about the SOLO pools? Why should a miner choose a SOLO pool and not mine to its own node?
You could find the detailed answer in our post Crypto Mythbusters: Solo Mining Pools Are Useless. In short, the SOLO mining pool provides you the better mining performance and at the end of the day, you get more coins compared to SOLO mining to your own node. You pay the small pool fee of 1-1.5% but you get a whole bunch of advantages. Opting for a SOLO mining pool like 2Miners ensures a more secure mining experience compared to running your own cryptocurrency node. With 2Miners, you benefit from a dedicated and powerful server, backed up by separate nodes for major cryptocurrency pools. Furthermore, 2Miners specialists constantly monitor upgrades for cryptocurrency nodes, ensuring you’re always using the latest and most secure version. This eliminates the need for you to spend time on updates and setups, providing a more stable and secure mining experience. On 2Miners you get detailed statistics including hashrate, shares, rewards, and more. You also get notifications by email or using the Telegram bot whenever your rigs go offline or a new block is found.
2Miners Pays Extra Rewards for Kaspa
One of the key reasons to choose 2Miners for Kaspa mining is its commitment to paying out the full block rewards, including any extra rewards. Unlike many other mining pools, 2Miners does not keep the additional 233 KAS when block rewards are doubled. Instead, they ensure that miners receive the full amount they’ve earned. This transparency and dedication to fair payouts make 2Miners an ideal choice for miners looking to maximize their rewards from Kaspa mining.
In the screenshot below you see the block rewards being always paid in full.
Mine KAS and Get BTC Payouts
Besides using a Kaspa wallet, 2Miners pool offers you the option to utilize any Bitcoin wallet for your mining endeavors. When mining coins such as ZEC, ETC, RVN, ERG, KAS, and NEXA, 2Miners enables miners to receive payouts directly in BTC. To leverage this facility, input your BTC wallet address into your mining software settings, replacing the standard Kaspa wallet address. We support all Bitcoin address formats: SegWit, Compatibility, and Legacy. Plus, BTC addresses set up on cryptocurrency exchanges are equally suitable, providing miners with added convenience and flexibility in managing their mining earnings.
How to Set Up ASIC for KAS
To set up your ASIC device for KAS mining on 2Miners, follow these simple steps to ensure a smooth and efficient mining experience. The 2Miners pool has dedicated ports for ASIC mining, with a 3434 port on the SOLO pool and a 2222 port on the PPLNS pool. These ports have a share difficulty of 17.59T, and the pool has been thoroughly tested and optimized to minimize invalid shares for ASIC devices. The chart below shows the number of invalid shares before and after the special port was introduced on 2Miners. As you see the difference is huge.
First, select the appropriate pool: either the SOLO pool for those who prefer to mine without sharing rewards or the PPLNS pool for a more traditional mining experience. You could estimate your rewards and the blocks you could get in SOLO mode using 2CryptoCalc KAS page. We recommend going to the SOLO KAS mining pool only if you get at least 1-2 blocks a day. If you see a smaller value according to your hashrate you’d better opt for the PPLNS KAS pool.
Configure your ASIC device’s mining software with the appropriate pool URL. For SOLO pool: stratum+tcp://solo-kas.2miners.com:3434
For PPLNS pool: stratum+tcp://kas.2miners.com:2222
Set your worker’s username to your Kaspa wallet address, which should follow this format. kaspa:qzd6sfx3a8gx3q0qjvsts0pc4gj62z8a4kdf6qcndq5fg42wwxpv6sv9ngmg9
You could use a Bitcoin wallet address instead as well, for example. bc1qnkyhslv83yyp0q0suxw0uj3lg9drgqq9c0auzc
Use ‘x’ as the password for your worker.
Save your ASIC device’s mining configuration and restart the device if necessary. Monitor your mining device’s performance on the 2Miners dashboard, where you can track your hashrate, luck, found blocks, and payouts. To view your statistics just enter your Kaspa wallet address in the search field at the top of the website. Take advantage of the free notifications provided by 2Miners for newly found blocks and rig shutdowns via email or Telegram.

How to Set Up GPU for KAS
Kaspa has been one of the most profitable coins for GPU mining, attracting many miners to its network. Its unique mining algorithm and rapid block generation have allowed GPU miners to obtain significant rewards. However, the recent emergence of ASIC devices designed specifically for Kaspa mining could disrupt this landscape.
The introduction of ASICs, like the IceRiver KAS KS1 and KS2, into the Kaspa network may have a substantial impact on GPU miners. As these powerful devices flood the network, the mining difficulty is expected to rise, leading to reduced rewards for individual miners. Consequently, GPU miners, who previously enjoyed considerable earnings, could face dwindling returns.
Despite this impending shift, it is still possible to mine KAS using GPUs and receive substantial rewards. However, the window for profitable GPU mining may be closing as more ASICs join the network. GPU miners should be prepared for the potential decrease in profitability and consider diversifying their mining activities or upgrading their hardware to remain competitive.
Currently, Kaspa is still one of the Top coins in terms of profitability for many GPUs. Please find below the most profitable coins for Nvidia 3070 (The calculations were done for 300x Nvidia 3070 GPUs).
Remember that it is always important to mine the most profitable coin. 2CryptoCalc.com helps you to find it for your hardware.
You could always find the settings for Kaspa mining on the Help page. We also have the ready-to-go bat files in our Quick Start Archive.
Please find below the settings for Kaspa Mining the most popular mining software. Use your Kaspa wallet address instead of YOUR_WALLET_ADDRESS. For example kaspa:qzd6sfx3a8gx3q0qjvsts0pc4gj62z8a4kdf6qcndq5fg42wwxpv6sv9ngmg9 or bc1qnkyhslv83yyp0q0suxw0uj3lg9drgqq9c0auzc. If you want, you can change RIG_ID in the bat file. Specify the name of the rig as you want it to be shown on the miner’s statistics page. This field is not mandatory. You could leave it empty. Length of RIG_ID – Maximum 32 characters. Use English letters, numbers, and symbols “-” and “_”. Example: rig-1
teamredminer.exe -a kas -o stratum+tcp://kas.2miners.com:2020 -u YOUR_WALLET_ADDRESS.RIG_ID
Settings to Mine Kaspa with Rigel
rigel.exe -a kheavyhash -o stratum+tcp://kas.2miners.com:2020 -u YOUR_WALLET_ADDRESS -w RIG_ID
Kaspa Dual Mining
Dual mining has become a popular choice for many miners, particularly in the case of Kaspa, where it is possible to mine two coins simultaneously with a single GPU. The most common combinations for dual mining with Kaspa are Ethereum Classic (ETC) and Ergo (ERG). This approach can lead to increased power consumption, but with the right settings and adjustments, miners can optimize their rigs for maximum efficiency.
When engaging in dual mining, both ETC/ERG and Kaspa can be mined effectively without compromising the mining efficiency of either coin. In some cases, dual mining can achieve more than 95% efficiency for ETC or ERG mining compared to mining these coins individually, while still maintaining up to 70% efficiency for Kaspa mining.
To optimize dual mining, miners should carefully consider their GPU settings, power consumption, and potential earnings for both coins. It is crucial to balance the mining intensity and power consumption of the rig to avoid any negative impact on the overall mining performance.
One option to achieve optimal results is to use mining software that supports dual mining and allows users to configure the settings for each coin separately. This way, miners can fine-tune their GPUs for maximum efficiency and profitability.
Kaspa Dual Mining with Nvidia 3070
We made some tests with the mining rig made of Nvidia 3070 GPUs. We mined separately Kaspa (KAS), Ethereum Classic (ETC), and Ergo (ERG) and then dual mining combinations such as Ethereum Classic + Kaspa and Ergo + Kaspa. For each of the tests, we checked the maximum possible stable hashing rate for the GPUs. Please find the results below.
Ergo: 172.4 MH/s
Ethereum Classic: 61.1 MH/s
Kaspa: 740.2 MH/s
Ethereum Classic + Kaspa: 60.4 MH/s for ETC + 543.9 MH/s for KAS
Ergo + Kaspa: 167.5 MH/s for ERG + 502.7 MH/s for KAS
The screenshot displaying ETC + KAS dual mining results highlights the potential for impressive hashrates when mining both coins simultaneously. Although the settings used in this experiment may not be optimal for energy consumption, the achieved hashrates emphasize the possibilities of dual mining as a way to maximize the use of a single GPU.
In this scenario, it’s as if one Nvidia 3070 GPU is mining Ethereum Classic, while another one is mining Kaspa. This “doubling your GPU” concept shows how dual mining can significantly enhance mining efficiency and profitability. By effectively utilizing the GPU’s resources for mining two coins, miners can increase their overall earnings without having to invest in additional hardware.
However, it’s important to note that to fully optimize this dual mining approach, miners should carefully consider their energy consumption and adjust their settings accordingly. Achieving a balance between high hashrates and reasonable power consumption is crucial for long-term mining sustainability and profitability.
Ethereum Classic + Kaspa Dual Mining Settings
Here’s an example of a bat file for Gminer that you can use for dual mining Kaspa (KAS) and Ethereum Classic (ETC). Please make sure to replace the example wallet addresses with your own.

How to Set Up Antminer E9 Pro to Mine ETC, ETHW or CLO
March 13, 2023
Bitmain recently released its most powerful Ethash/Etchash ASIC mining device – Antminer E9 Pro. 2Miners developers have already tested it and adjusted the pool firmware to support this miner.
Antminer E9 Pro Hashrate
Antminer E9 Pro has a hashrate of 3 680 MH/s on Ethash and Etchash algorithms and consumes 2200 W. This is the most powerful and most efficient Bitmain Ethereum miner so far.
The hashrate of this single ASIC is as high as 30 top-range Nvidia 3080Ti graphics cards. The information on the released quantities of this beast was not disclosed by the manufacturer so it is hard to predict if these machines could affect the Ethash/Etchash algorithm mining profitability.
What to Mine on Antminer E9 Pro
It is not possible to mine Ethereum since the “Merge” the so-called switch to Proof-of-Stake. However, there are other coins on the Ethereum algorithm Ethash that are still mined such as Ethereum PoW (ETHW) or Callisto (CLO). There is also a possibility to mine Ethereum Classic which uses the slightly different mining algorithm Etchash.
Let’s enter the ASIC hashrate (3680) into Etchash and Ethash fields on the 2CryptoCalc.com mining calculator. The calc will show the profitability prediction.
Ethereum PoW is now the most profitable coin for this miner. You could get $10.25/day not taking into account the consumed electricity costs. Ethereum Classic and Callisto’s profitability is slightly lower. However, we highly recommend you check the profitability from time to time as it could change depending on the cryptocurrency prices and hashing power participating in the mining of each of the coins.
Choosing the Mining Pool for Antminer E9 Pro
There are not many pools that support Antminer E9 Pro. Currently, only 2Miners supports this ASIC from the top Ethereum Classic pools. 2Miners developers have re-writed and adjusted the pool software in order to support Antminer E9 Pro and successfully tested this machine on Ethereum Classic pool. In terms of hashrate 2Miners is at the top of the ETC mining pools in the World so the pool finds a lot of blocks daily and the miners get consistant rewards.
Another awesome feature available only on 2Miners ETC pool is the possibility to get payouts in Bitcoin. There are no complicated settings. All you need to do is specify your Bitcoin and not Ethereum Classic address in the Antminer settings. The pool will automatically detect you want to receive the payouts in BTC. Currently more than 1 000 miners are using the Bitcoin payouts in the Ethereum Classic pool.
2Miners developers have successfully tested the Antminer E9 Pro in other Ethash pools presented on 2Miners.com: CLO and ETHW. These coins have absolutely no other reliable options to mine but 2Miners. Check the hashrate distribution below.
Antminer E9 Pro Profitability
Let’s check the profit we could generate with this device using the 2CryptoCalc mining calculator. Choose the number of devices you have on the main page of the calc or just go to the special page of E9 Pro.
Currently, you could get $10.83/day mining Ethereum Classic and slightly less on Ethereum PoW ($10.52/day) and Callisto ($10.44/day). However, we recommend you check the calculator regularly as these values could differ. The Most profitable ASICs page could help you compare the E9 Pro profitability with other ASIC miners.
Antminer E9 Pro Settings
Go to the settings tab. You don’t need to change the mining algorithm, no matter if you mine Etchash or Ethash. The correct settings could be always found on the help page of each mining pool: ETC, ETHW, CLO.
Save the settings and ASIC would start. Please wait patiently as it could take up to 30 minutes for Antminer E9 Pro to generate the DAG file and start mining.
How to Setup Antminer E9 Pro for Ethereum Classic Mining
The settings are quite straightforward. You have 3 fields to specify the mining pool and 3 fields to specify the wallet address. We recommend you use the same pool and the same wallet address for all three rows. Check the screenshot above. There are 3 locations available for the ETC pool: Europe, Asia, and the US. Always use the Europe connection by default.
Please find below the basic connection parameters. Remember that you could use not only ETC wallet address but the BTC wallet address as well.

How to Setup Antminer E9 Pro for Ethereum PoW Mining
Sometimes Ethereum PoW is more profitable than Ethereum Classic and you want to mine ETHW instead of ETC. ETHW settings are similar to ETC. There are no complicated modifications. Specify the pool and the wallet address. Please remember that only ETHW address works. BTC payouts are not supported for this coin. For those miners who want to mine to the local/mobile wallet, we highly recommend Metamask. By default, ETHW is not supported but you could add the Ethereum PoW network manually. Check the detailed guide on how to do that. A lot of exchanges support ETHW deposits as well. For example ByBit, OKX, or Kraken.
Here is the basic setup for ETHW mining.

Miner since 2017, the 2Miners pool co-founder. Became interested in cryptocurrencies at the dawn of the latest bull run and bought his first graphics cards. After having built and set up a few mining rigs, he realized that existing mining pools didn’t satisfy him – that’s how the idea of creating the 2Miners pool was born.
John published a series of articles about the basics of cryptocurrency mining. He gave valuable tips on how to buy ASICs and GPUs from abroad and then shared their mining performance. On the website, you can find early articles about cryptocurrency mining, blockchain in general and mining pool operation principles. The readers gave positive feedback on John’s practical guides, such as building an Ethereum mining rig and Nvidia 1080ti overclocking.
February 2023 Work Progress Report: CKB, ZEC, ERGO, FLUX Node Updates.
March 1, 2023
Firo wallet problem resolved, Flux reward halving, multiple node updates.
FIRO Wallet Problem Resolved
Last month we experienced a problem with the FIRO wallet. In some cases, this caused the payment delay. Thanks to the FIRO developers the problem has been resolved successfully. The payouts are now being processed without any issues. All pending payouts have been processed as well.
The block reward for miners was reduced from 37.5 FLUX to 18.75 FLUX. More info on GitHub.
That means all the miners get now two times fewer rewards than they get early. Please pay attention! 2CryptoCalc calculator was updated.
Cryptocurrency Node Updates
We updated some of the cryptocurrency nodes in February. It is always very important to have the latest node firmware to provide our miners with the best mining experience.
CKB 0.108.0-rc2 fixes some minor bugs, resolves the error of block filter hash calculation, and fixes transaction rebroadcast.
ZEC 5.4.1 includes some hotfixes.
ERGO 5.0.7 adds the support of additional indexes, fixes the mempool inconsistency and includes other updates.
Zelcash version v6.1.0-782daee was a mandatory release. It includes Flux rename adjustments, RPC optimizations, performance improvements, snapshot creation, and RPC calls updates, multiple processing optimizations, and various bug fixes.

January 2023 Work Progress Report: New API for CTXC, FIRO Wallet Problem
February 1, 2023
New API and statistics pages for Cortex, Ergo block reward reduction, Firo wallet problem, Beam delisting from Binance.
Cortex New API
We updated the Cortex (CTXC) mining pool. Now it uses the latest API version. That makes the work of our services and third-party applications faster. Moreover, this means that the new statistics pages are available for Cortex.
Now each miner has detailed hashrate statistics and share statistics. You are also able to change the payout threshold in the CTXC pool.
You may need to clear your browser cache with Shift+Ctrl+R to see the update.
You could find the detailed information on ERGO emission on the official ERGO post.
FIRO Wallet Problem
We experienced a problem with the FIRO wallet. For some reason, the wallet doesn’t allow us to spend the mined coins and we are not able to process the payments. FIRO developers are aware of this bug and they are helping us to solve the issues asap.
We are able to submit some payments from our own funds at a slow pace, so you might see some Firo payments going.
We’ve changed the wallet to a new type and right now we are waiting for the solution from FIRO developers that unblocks the funds on the old wallet. When the FIRO issue is resolved, we process all the pending payments immediately.
BEAM Delisting from Binance
Binance delisted BEAM coin on January, 26. BEAM deposits are not credited to Binance anymore. We are not able to recover your funds or transfer the unpaid balance from one wallet address to another one (see FAQ).
If you still mine to a Binance BEAM wallet, please change it immediately!
If you mine BEAM the best way is to use the official BEAM desktop or mobile wallet software so you always hold the private keys from your wallet and control your funds.

December 2022 Work Progress Report: Year-end Results
December 31, 2022
ZEC, ERGO, CORTEX node updates, work in progress, the year 2022 results.
Cryptocurrency Node Updates
The new node software was installed to keep all the mining pools up-to-date.
Ergo Protocol Reference Client 5.0.4 has multiple code optimizations. The release details are available on GitHub.
Zcash v5.3.2 and previously v5.3.1 solved some minor issues and improved memory usage. The release details are available on GitHub.
Cortex 1.10.36 release called by the name of Lionel Messi. The release details are available on GitHub.
Mining in 2022. Year-end Results
This was a tough year for the cryptocurrency industry and particularly crypto miners.
First, TerraUSD/LUNA, Three Arrows Capital, Celsius, and FTX collapses in 2022 led to a tremendous crypto market drop.
Second, but no less important, the Ethereum coin switched to POS from POW. The end of the ETH mining era was the most painful event ever for the graphics card mining community. Approximately 95% of all GPU miners were mining ETH. The end of Ethereum mining resulted in a huge hashing power release. All other GPU-mined coins and algorithms immediately gained many miners and as a result, the profitability fell respectively. The newly emerged coins such as EthereumPoW didn’t help that much.
Hopefully, the mining community is strong enough and we still have more than 50K miners online. This year we removed not only ETH, which is not mined anymore, but also Expanse (EXP), Metaverse (ETP), and MimbleWimbleCoin (MWC). We have 17 coins available in 2Miners now and our developers work hard to bring you the new ones. Currently, we are working on Kaspa (KAS).
Bitcoin payout was a great success last year as BTC payments are very convenient for the major part of the miners. This year we spread the BTC payments feature to other coins. You can now get paid in Bitcoin if you mine Ravencoin, Ergo, Ethereum Classic, and Zcash. The BTC payments for Horizen are almost ready as well. We would love to make this feature available for all the coins we have but sometimes it is just impossible to find a trustworthy crypto-exchange with the required trading pairs and trading volumes, and reliable API as well.
No matter if you trust in the upcoming crypto bull run or not, cryptocurrency mining stays and we always do our best to provide you with the best mining experience possible.

November 2022 Work Progress Report: ZEC and ERGO Node Updates
December 1, 2022
ZEC and ERGO node updates, mining rewards fluctuation due to the market instability, BTG delisting from Binance.
Cryptocurrency Node Updates
We updated some of the cryptocurrency nodes in November. It is always very important to have the latest node firmware to provide our miners with the best mining experience.
Zcash (ZEC) 5.3.0 includes performance improvements and reduces concurrent memory utilization during scanning among other memory and performance-related optimizations in the Zcash node.
Ergo Protocol Reference Client 5.0.3 contains different node upgrades including slicing in /scan/unspent boxes by inclusion height and more. The full list of features could be found on GitHub.
Mining Rewards Fluctuations
One of the biggest crypto exchange platforms FTX crashed in November. The problems tumbled into the open on November 2nd when CoinDesk published a report questioning the financial health of both FTX and Alameda Research, controlled by FTX. It was indicated that much of Alameda’s balance sheet was made of FTX native tokens FTT.
The FTX collapse led to a drop in the cryptocurrency market including the GPU/ASIC-mined coins. This resulted in the rewards decrease for the miners. Some of the miners switched off their equipment as mining is not more profitable for them anymore. Even Bitcoin hashrate dropped in November by more than 10%.
At the end of the month the market a little bit stabilized. The prices of many coins went up. So did the mining rewards. We recommend using 2CryptoCalc.com to find the most profitable coins for your hardware. It is very easy to use as you could just enter the number and the models of the graphics cards you have. Of course, you could also enter the hashrate values straight away if you know them.
BTG Delisting from Binance
Attention Bitcoin Gold (BTG) miners! Binance cryptocurrency exchange delisted BTG on 2022-10-24. Our support team is still receiving messages from the miners who missed this news. If you mine Bitcoin Gold and you use the wallet generated on the Binance crypto exchange, please change your wallet address immediately. Our pool is anonymous and we are not able to transfer the mined coins from one wallet address to another wallet address.
