raspberry-pi-3-model-b

Most crypto currency miners should be very familiar with the Raspberry Pi, the small and inexpensive Linux-based “computer” that is often used to run big ASIC miners without the need of a dedicated powerful PC. The RPi however can be used for other things such as running a full Bitcoin or other crypto currency node with the help of a large USB drive or running a wallet for PoS for example. So the announcement of a new faster Raspberry Pi 3 could be of interest to a lot of people, especially considering the fact that the new model comes with built-in WiFi and the price remains the same as with the old model 2 – $35 USD, with the RPi 2 still available for anyone that needs it.

Raspberry Pi 3 Specifications:
– Processor: Broadcom BCM2387 chipset, 1.2GHz Quad-Core ARM Cortex-A53, 802.11 b/g/n Wireless LAN and Bluetooth 4.1 (Bluetooth Classic and LE)
– GPU: Dual Core VideoCore IV Multimedia Co-Processor. Provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode. Capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure
– Memory: 1GB LPDDR2
– Operating System: Boots from Micro SD card, running a version of the Linux operating system or Windows 10 IoT
– Dimensions: 85 x 56 x 17mm
– Power: Micro USB socket 5V, 2.5A

Raspberry Pi 3 Connectors:
– Ethernet: 10/100 BaseT Ethernet socket
– Video: Output HDMI (rev 1.3 & 1.4 Composite RCA (PAL and NTSC)
– Audio Output: Audio Output 3.5mm jack, HDMI,
– USB: 4 x USB 2.0 Connector
– GPIO Connector: 40-pin 2.54 mm (100 mil) expansion header: 2×20 strip providing 27 GPIO pins as well as +3.3 V, +5 V and GND supply lines
– Camera Connector: 15-pin MIPI Camera Serial Interface (CSI-2)
– Display Connector: Display Serial Interface (DSI) 15 way flat flex cable connector with two data lanes and a clock lane
– Memory Card Slot: Push/pull Micro SDIO

The dimensions and layout of the new Raspberry Pi 3 Model B are the same as with the RPi 2 Model B including the connectors, so it should be compatible as a direct replacement for the older unit if you are already using it for a project. The faster CPU can be a good upgrade for tasks requiring more processing power such as running a crypto currency node, the GPU is the same as with the old model, but clocked higher and you get WiFi and Bluetooth built-in for easier wireless network and peripheral connectivity.

supermicro-file-storage-1

With different projects like Storj, Sia or Burst the use of hard drives and storage space tied to crypto currency mining or sharing files with crypto token rewards may become more attractive to users. With hard drive sizes growing and solutions available for building multi terabyte storage systems available building a multi-terabyte storage solution for use with the projects mentioned above might be viable. We’ve already covered a more affordable home user option for Building an 8 TB Storage Solution for Storj’s DriveShare, but there are options for much larger scale solutions that are still not too expensive, though probably still above the budget of the average home users. You need to look at more serious server companies for products that are designed for file servers for examples as we are going to be using a Supermicro solution for hosting 24 HDDs in a single rack-mountable chassis. The solution you are seeing here is not particularly designed for use with Burst, Sia or Storj, but we wanted to give it a try using it for them to get an idea what you may expect.

supermicro-file-storage-2

The 4U chassis used from Supermicro is designed for file servers in a rack-mountable format, supporting 24 3.5-inch hard drives, though the company offers many different products for 2.5 and 3.5-inch drives all the way up to 90 drives per system and apart from complete solutions you also have the option to go for HDD expanders for many drives that are being connected to separate systems. We have used 24 hard drives from Hitachi with a capacity of 6 TB which in theory should result in 144TB of storage space (in non RAID configuration with mirroring or spare drives), but in reality due to how HDD capacity is being calculated we are actually getting just 130 TB of usable space. For the purpose of the already mentioned crypto related projects you’d probably want to go for more space than redundancy, especially if you are building such a solution with that many hard drives.

Storj and Sia are supposed to ensure redundancy and data availability by replicating user stored data or multiple systems and for Burst that uses HDD space for mining you may just regenerate the plots in case you have a problem with any of the hard drives available. With Storj’s DriveShare you may have multiple drives shared, but with SIA or Burst you may have to do a HDD spanning configuration, so that all of the available space will be usable as a single drive. What you should be well aware of is the time it may take to fill up a very large space such as 130 TB with data using any of the projects. It will take literally days to generate HDD plots of that size for Burst mining, or to generate test data for the Storj DriveShare service as it currently does not store user data while still in testing phase. For Sia that already has an operating network and users are actually sharing data the waiting time to actually utilize that free space might take months and you needing to have a low price to attract more users. So at this point in time you probably can go with much smaller storage solutions and a 24-drive monster like this might be a bit overkill, especially considering the amount of money you will need to pay for the hardware and the expected ROI for using it as a mining medium or storage sharing solution that you get paid for. But then again, if you need to build one for different tasks and you have some free space on it you might want to give the three mentioned services a go…

yobit-altcoin-exchange

There are quite a lot of large crypto currency exchanges that are focused on the mail crypto currencies such as Bitcoin, Litecoin, Ethereum, DOGE and a few more. When talking about altcoins however there are not that much options available that have a large number of coins available for trading, especially when talking about more recent coin launches. The first two large ones that come in mind are of course Bittrex and Poloniex, but getting an altcoin listed there and keeping it long term may not be that easy. So here comes YoBit, one of the biggest altcoin exchanges at the moment that currently has 467 active trading pairs and and some daily trading volume on at least half of them.

It is not just an crypto currency exchange however, as on YoBit you also have a built-in Dice game that seems to support all currencies in the exchange, free coin giveaways for many coins with the ability to claim free coins as well as to donate coins for the giveaways, there is even a coin info database to help you easily find more information for an altcoin you might not be familiar with. The exchange is also running coin ICOs as well as has free and paid listing options available for including new coins, something that can be useful for new coin developers that want to get their new project up and running on an exchange.
