The recent public announcement of the Meltdown and Spectre critical vulnerabilities in modern processors that could leak passwords and sensitive data are really something that you might want to pay attention to if you are into crypto. Since these hardware vulnerabilities allow programs to steal data which is currently processed on the computer they could potentially lead to passwords and/or other secure data getting leaked and this poses risk for crypto currencies getting stolen from your computer or mobile device. The good news is that various companies have already released operating system and device patches that try to fix or mitigate the potential problems that might be caused by the exploits. So what you should make sure is to update your computer and mobile devices with the latest security patches in order to at least minimize the chances of getting affected by the Meltdown or Spectre exploits.
Meltdown
Meltdown breaks the most fundamental isolation between user applications and the operating system. This attack allows a program to access the memory, and thus also the secrets, of other programs and the operating system. If your computer has a vulnerable processor and runs an unpatched operating system, it is not safe to work with sensitive information without the chance of leaking the information.
Spectre
Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. In fact, the safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre. Spectre is harder to exploit than Meltdown, but it is also harder to mitigate.
Patching and securing your GPU mining rigs might not be that much of a priority, but computers or mobile devices where you use or store local crypto wallets or passwords for accessing online wallets and/or other crypto related services such as exchanges must be your first priority. Below you can find a link to security information, updates and patches for fixing the problem or at least mitigating the possibility to be exploited using the Meltdown or Spectre, so make sure you check different software and hardware manufacturers recommend that you do and install and patches and updates that they recommend.
If you have been following us for a while already you have probably noticed that we are not big fans of ICOs and we aren’t covering much of these, even though lately there is a boom of Initial Coin Offerings and it seems that pretty much everyone is releasing tokens for something. There are however some that we do mention and take part into, mostly in serious ICOs that are being pushed by entities that already have some good product or service available and have some background and not just promises that might as well turn out to be empty. Once in a while there are some that are really worth talking about and that goes not because they have generated a lot of noise or have managed to secure insane amount of funding, but because they are really something worthwhile, different, disruptive and so on. A recent such example is Brave’s Basic Attention Token (BAT) that we have covered as we’ve been following the development of the Brave browser for a while already.
According to a welche Aktien kaufen 2020 report, another interesting ICO that we think is worth talking about and taking a part in is the Giga Watt (WTT) Token that is currently ongoing and will continue until July 31st or until all of the 30 Million tokens are sold. The Giga Watt WTT token are being issued on the Ethereum blockchain like many others that we have seen recently, but what is different here than most other ICOs is the fact that the launch of the ICO is together with a whole platform to support the token (as well as other future tokens). One of the issues with Ethereum ERC20 tokens we are seeing is that normally they are not very easy for people that are not more into Ethereum to take part into… the process is just really not that easy for not so technical or “into crypto” type of people.
The WTT tokens are being distributed via the new Cryptonomos platform for token sales as well as management. The Giga Watt (WTT) Token is essentially the first token launched together with the platform for easy purchase and management of the available tokens by the user. This eliminates the need for the user to look for compatible Ethereum wallets and to do complex things in order to take part into an ICO based in a crowdsale essentially significantly lowering the requirements and removing many of the obstacles. Thanks to the Cryptonomos platform you can easily transfer Bitcoin (BTC), Ethereum (ETH) or cash via a wire transfer and use them to purchase WTT tokens, and probably other tokens in the future as well. You should be also able to transfer tokens in and out of the platform when they are abvailable just like you would do if using a compatible Ethereum wallet for interacting with smart contracts. Of course there is the other point of view regarding the use of a dedicated platform – you are not in full control of your tokens like you can with an Ethereum wallet for example where you hold the private keys for the wallet.
Let us get back to Giga Watt (the former MegaBigPower), a USA-based company offering crypto mining hardware as well as hosting for it and of course enough electricity to power it and keep it cool. The company offers also users to host their own existing miners and even an add-on paid option of emergency equipment repairs in case of an issue in order to minimize downtime. The release of the WTT token allows the token holders to gain access to Giga Watt’s facility at a lower hosting rate, which in turn significantly increases the mining rewards. Each Giga Watt Project Token (WTT) represents the right to use the Giga Watt processing center’s capacity, rent-free for 50 years, to accommodate 1 Watt’s worth of mining equipment power consumption. Token owners can use the capacity they purchase to accommodate their own miners or if they don’t own or plan to purchase any miners to take advantage of the hosting offer to just rent it out to other users. The idea that Giga Watt has is to use the token sale to be able to expand their capacity and to reward token holders that help them achieve that, so a win-win for both sides. For all the details about the Giga Watt (WTT) token and the plans of the company issuing it you should take a look at the detailed WTT token whitepaper (PDF) where everything is explained in much more details and all your questions should be answered.

Siacoin (SC) has been picking up recently and there have been talks about privet mining pools available, but the good news is that you can already GPU mine the SIA crypto tokens that are powering a decentralized storage network in an open pool. The open Siacoin mining pool already available is sia.nanopool.org and you can join it and start mining in no time. The pool does not need a registration, all you need to have is a wallet address – generate one with a SIA local wallet or use an exchange generated wallet from Poloniex or Yunbi. You can download the GPU miner for Siacoin written in in Go for pool mining (source) compiled and ready to be used from the link below (64-bit release for Windows) or use the latest Claymore Dual Miner that brings support for Dual Mining Ethereum along with Decred or Siacoin as a second coin (previously only Decred was available for dual mining).
The SIA Nanopool pool uses PPLNS payout scheme, has a fee of 2%, executes payouts once a day with a minimum payout currently set at 5000 Siacoins. Out test with the Siacoin Go miner for Siacoin shows about 1116 MHS as a hashrate for a single Radeon R9 290X GPU without overclocking, so you can have that number as a reference. The miner also works on Nvidia GPUs (it is still using OpenCL, not CUDA), as a reference number you can expect to get about 803 MHS from a GTX 970, do note however that for Nvidia-based mining rigs the go miner is the only choice as the Claymore dual miner is only for AMD GPUs. If you want to focus on mining Ethereum and mine Siacoin as a secondary coin and have AMD GPU mining rigs, then you can also try the latest Claymore dual miner version 5.0 that now gives you the choice for mine Decred or Siacoin besides Ethereum. Please report your hashrate and success in running the miner on different hardware, both AMD and Nvidia-based GPUs, in the comments below. should you decide to try mining Siacoin.
