Miners with less than 1.5 bitcoins mined over the past three days will pay a 2.6 percent fee.In addition, for a limited time, all miners can enjoy the 2.0 percent fee regardless of whether or not they mine 1.5 bitcoins over three days by using the following hashrate code: f885fc59-2b60-4cf7-ac3e-239799e67dc4 Also, going forward, pool members will receive 10 namecoins per bitcoin mined.bitcointalk new usersNamecoins are currently trading for 0.0006 BTC per namecoin, or roughly $0.31.BTCC Pool will award miners each day's namecoin mining rewards on the subsequent day at 10:00 A.M (UTC+8).This means that a miner who contributes one petahash to BTCC Pool for a month would get $112.82 more in mining rewards than they did before.With the additional namecoin mining rewards, miners can enjoy fees as low as 1.43 percent.Please see the BTCC Pool FAQ for more information.For example, if a miner earns three bitcoins in mining rewards on Monday based on her contributed hashing power, the pool will award her 30 namecoins on Tuesday as a reward for merged mining.

The namecoins will be distributed to miners' specified namecoin wallets.Miners will need to set a namecoin wallet in their BTCC Pool account settings in order to receive namecoin mining rewards.Miners who do not specify a namecoin wallet will be considered as having forfeited their namecoin mining rewards.Namecoin is a cryptocurrency whose blockchain is the basis of a decentralized domain name system that includes the .bit domain name./exchanges/ The namecoin rewards that BTCC Pool announced today are made possible through the merged mining of bitcoins and namecoins.Merged mining is a process in which miners contribute hashing power to more than one digital currency's network.One of our customers found that one individual had been running for months an illicit Bitcoin mining operation that pumped his employer’s electricity bill to pocket some Bitcoin.This post explains how Talaia was able to flag this activity (and how it can do the same for you).Bitcoin is an exciting technology.

In a nutshell, it is a form of “internet money” that runs on a peer-to-peer network with no central authority.It allows any person or organization to receive direct payments over the Internet, skipping any middle men.Bitcoin MiningBitcoin is widely perceived to be a disruptive technology that can some day compete with other forms of payment.For example, it could one day replace Paypal or credit cards.Bitcoin has experienced a meteoric rise in both attention and value.It has multiplied its value by ~600 in the last four years (as of this writing), and is now thriving.It is estimated that Venture Capital firms will invest a cool $300 million on Bitcoin centric startups in 2014.Arguably, the most widely misunderstood aspect of Bitcoin is mining.Bitcoin is hard to grasp, and some aspects of it seem almost magical, especially for those who do not have a background in Computer Science and cryptography.There are many resources that explain Bitcoin mining better than I would mange to (check for example this video).

But let me give a very simplified view in this post.In essence, a Bitcoin miner contributes computing power to the network by performing a huge number of calculations.The more aggregate computing power that Bitcoin miners contribute, the more secure Bitcoin becomes.But computing power does not come for free: it requires high-end hardware that is power hungry.To offset these costs, Bitcoin rewards miners for their contribution to the network by awarding them coins.The reward is fixed (currently, 25 coins every 10 minutes) and miners share it, proportionally to the computing power they contributed.Another interesting aspect of Bitcoin mining is the phenomenon of mining pools.For reasons that escape the scope of this post, Bitcoin rewards miners in a peculiar way.I would need paragraphs to explain all details, so let me simplify it to the following analogy: Bitcoin runs a lottery round every 10 minutes.In each round, each miner has an amount of tickets proportional to the computing power he or she contributes.

In each round, a single winner takes down the full prize.(Again, this is only an analogy, but the end result is roughly equivalent.)This means that miners that have little computing power could have to wait for months or years to win the next lottery round, depending on their luck.Instead, miners form alliances called pools, where they aggregate their computing power.This increases their chances of winning a reward sooner, which they split.This does not give them higher rewards, but it makes their income more steady and predictable.Many individuals and companies have been attracted to Bitcoin mining (akin to the gold mining rush).However, since miners share the rewards, the sheer number of miners that have joined the network have made mining a marginally profitable endeavor, as rewards are split among more and more miners.So, how can a miner stay profitable?The main cost of an ongoing mining operation is electric power.Miners who manage to squeeze more computing power will get a larger share of the reward per watt.

Those who use inefficient mining hardware will fall behind.Their electricity bill will be higher than the mining rewards, thus becoming unprofitable.Besides optimizing hardware for power efficiency, there is another way to run a profitable mining operation.Can you guess how?By stealing electric power.When crooks manage to find a source of electric power, they can profit from it by running an illicit Bitcoin mining operation.Ongoing mining costs drop to zero, and they can reap the rewards of participating in mining while making somebody else pay for the costs.I still have not found on the news any instance of an illegally powered data center devoted to Bitcoin mining.This would be a hard one to pull off.However, illicit mining operations are happening today: we are not being hypothetical.There are two ways in which this is already happening.One is via malware, the other is to abuse easy-to-grab power sources.Bitcoin mining malware has been spotted in the wild.This is a particularly insidious form of malware: it steals energy from unsuspecting computer owners, and turns it into money for the creators of the malware.

Crooks gain access to large numbers of infected computers, and push their mining malware to maximize profits (or damage, depending on the point of view).The second way one can run a Bitcoin mining operation without paying for the electricity bill is to steal it from their employer, tenant, or whatever available source.This is happening today: see hereor here.The definitive way to detect illicit Bitcoin mining operations is by tracking power usage.However, today, many organizations and companies are not going that far in terms of accounting for power usage.This is natural since, until Bitcoin was born, there was little potential for abuse.An alternative way is to detect miners by inspecting network traffic.This can be achieved by checking for computers that connect to well-known Bitcoin mining platforms or participate in the Bitcoin P2P network.Note that the former is a red flag that indicates mining activity, while the latter merely raises suspicion.Talaia is our cloud-based network visibility service.

Its main strength is that it can run as a service.That is, it does not require the deployment of any extra hardware or software in your network.Instead, you merely need to configure your switches to send us aggregate traffic reports.This is achieved using industry-standard protocols such as NetFlow, IPFIX or sFlow.So, you simply set up your instance, send it your NetFlow data, and gain visibility over your network traffic.Behind the scenes, Talaia uses a complex machine learning based algorithm to tell which application generated each connection (for example, bittorrent, SSH, web, etc).We extended this algorithm to detect Bitcoin as follows.First, we feed it an updated list of nodes that participated in the Bitcoin P2P network.Second, we also fed it a list of IP addresses that correspond to the most popular mining services.This way, Talaia is able to perform Bitcoin mining detection.We are not aware of any similar network visibility product that has Bitcoin mining detection capabilities, so I will go ahead and assume that Talaia is the first network visibility product that can detect Bitcoin mining.
