Russians Design а ‘Beautiful’ Mining Rig

Form Meets Function in the “Freer” Miner

Russians Design а ‘Beautiful’ Mining RigYou have to admit, mining rigs are not the best-looking pieces of engineering. That’s okay when talking about industrial-grade hardware; racks upon racks of ASICs in some former factory in Russia, China, or America. But domestic devices, homemade or purchased, are not aesthetically pleasing. They are often just a skeleton frame, with half a dozen video cards, cables and fans, and, if you are lucky, you’ll get all that in an ugly square box with the fans visible on the outside. Whatever the case, it’s not something you would want to see in your living room.
A Russian design studio has decided to remedy that. They’ve recently launched their first “beautiful” miner, an aesthetically pleasing home mining device that is modular and customizable. It offers a number of ports on the back, a choice of displays on the front showing the mined coins, and it comes in different color schemes. The designers have described their creation in a poem published on their website lauding its curved shapes, extraordinary beauty and discreetly hidden cooling system: “More fashionable than an iPhone, the new geek’s dream.”

The prototype, called “Freer”, comes as a shell and manufacturers are free to place their own mining hardware inside the box. Art Lebedev, the studio run by famous Russian designer, entrepreneur, and blogger Artemy Lebedev, has not wasted time on the engineering side but has focused primarily on the design aspect of the project. The company did not reveal details about the client who ordered its first artistic mining rigs but published some of the sketches drawn during the development of the final concept.

Lower Taxes for Miners Proposed in Russia

The fashionable mining rig has been announced at a moment when the Russian crypto community, not least miners, is eagerly awaiting the final decision of authorities in Moscow regarding the legalization and regulation of crypto-related activities such as cryptocurrency mining. Three bills dealing with the matter were voted on first reading this spring with their final adoption expected during the fall session of the State Duma, the lower house of Russia’s parliament.

Russians Design а ‘Beautiful’ Mining RigThe new legislation should regulate various aspects of the crypto industry including the circulation and exchange of cryptocurrencies with rubles and foreign fiat. The taxation of crypto incomes and profits is one of the outstanding issues. Currently, revenues from crypto mining are subject to the Russian flat income tax rate of 13%. Different ideas have been discussed with the latest one coming from the Russian Association of Cryptocurrencies and Blockchain (RACIB) and one of its members.
A company called Crypto Universe as well as RACIB has proposed to Finance Minister Anton Siluanov to allow private individuals dealing with mining to register as self-employed persons. This would lower their taxes to only 3-5%. According to Crypto Universe, there are more than 350,000 individual miners in the Russian Federation. Due to the lack of an adequate regulatory framework, many of them operate unofficially and cash out their minted coins illegally. As a result, the state treasury loses an estimated 2 billion rubles (almost $30 million) in uncollected tax annually.

Japanese Company Trials BTC and Smart Contracts in Real Estate Transactions

BTC and Smart Contracts in Real Estate

Japanese Company Trials BTC and Smart Contracts in Real Estate TransactionsJapanese real estate company Ruden Holdings (TYO:1400) recently announced the results of an experiment using its newly-created “virtual currency real estate settlement platform.”
Japanese Company Trials BTC and Smart Contracts in Real Estate TransactionsThe company explained that the trial, which involved BTC and smart contracts, was conducted in collaboration with Blockchain Global Limited (BGL). The two companies partnered in April to develop the settlement system and a “virtual registration data inquiry system,” Ruden detailed, adding:
For the settlement of bitcoins (BTC) used in the property sale, Bitflyer’s web service and API functions were used.

Some parts of the system, such as time stamping of the contract, used the NEM test network, the company added. Bitflyer is Japan’s largest crypto exchange by volume. However, the exchange halted registering new users after receiving a business improvement order from the country’s financial regulator in June.

The Experiment

Japanese Company Trials BTC and Smart Contracts in Real Estate TransactionsThe experiment began with a seller listing a property to sell and a buyer looking for one to buy. The buyer then filled out an offer to purchase the property, which the seller confirmed.
“The buyer then sent the virtual currency (bitcoin) to the Ruden company’s virtual currency account,” the company described, elaborating:
As soon as Ruden (system) confirms the remittance of the virtual currency, we will execute the contract and [convert the] virtual currency to Japanese yen. In addition, a notarized sale [and] purchase agreement is promptly shared with [the] buyer and seller.
Other forms including the property registration application and requests to acquire other necessary documents are also automatically sent in order to execute the sale of the property.

Many Advantages Over Traditional Systems

Ruden then outlined many advantages it observed from the experiment.
Japanese Company Trials BTC and Smart Contracts in Real Estate TransactionsFor buyers and sellers, the company explained that using smart contracts and crypto payments makes it “possible to drastically shorten the time required” to perform each step of the process, including depositing money.
“Smart contracts eliminate the need for manual work and conditions,” the company detailed, adding that “the time to negotiate and conclude can be shortened compared to the current work.” Furthermore, the system also reduces “trouble such as refusal” to hand over the property after payment has been made.
Overall, Ruden emphasized:
It is not only to improve the efficiency of operations, but also to prevent unforeseen circumstances.
In addition to building the two systems above, the company announced last week the establishment of an overseas subsidiary in Singapore for the issuance of its own token.

“Adding BCH brings us to having 6 of the top 7 coins available via Netcoins. With just EOS left among the top 7 coins, we are giving investors a compelling reason to use the Netcoins network for all their crypto needs, whether via OTC or via our strong retail network,” announced Netcoins CEO Mark Binns.

Netcoins has been around for three years, and is from Vancouver, Canada, where it initiated its virtual ATM business in 2015. “Merchants from all over the world can sign up for the Netcoins service and be provided with a platform that allows them to have a Bitcoin ATM without having to buy a machine. The application can work on a smartphone or tablet allowing merchants to offer the sale of Bitcoin without the substantial costs involved with the purchase of a device or the physical space needed within the store,” we profiled previously.

For BCH, it’s another adoption score, one in a string this year. Netcoins services 21,000 retail locations throughout Canada, Europe, and Australia. In its announcement the company promised immediate access to purchase BCH through its OTC Private Brokerage Services.

Adoption Milestones Keep Coming for BCH

Just days ago, these pages reported how “the Atlanta-based firm Bitpay announced that its merchants can now receive settlement in bitcoin cash (BCH). Not only can Bitpay merchants accept the decentralized digital currency and keep all the bitcoin cash, but they can also split their funds into a fraction of fiat and BCH as well,” a significant step for merchants tired of changing out from bitcoin core (BTC) back into BCH after settling.

And a week prior to the above, “a new bitcoin cash SPV client available called Pixel Wallet that provides users with the ability to attach BCH transactions to pictures” was released. “Basically, bitcoin cash users can send BCH transactions in a steganographic manner with the wallet hiding funds in plain sight. Pixel Wallet was initially announced and launched on the BCH testnet during the first week of August, and the project’s developers explained the application would be the first of its kind.”

A Look at What It Was Like to Operate the Lightning Network’s Largest Node

Compiling a Lightning Network Node
The Lightning Network is a second layer payment protocol that many people believe can solve Bitcoin Core’s (BTC) scalability problem. The reason for this is because the LN system works on top of the BTC chain and because of this factor there would be fewer on-chain transactions. Essentially the system comprises a great number of participating nodes that can send transactions through bidirectional payment channels. Alongside this, there’s been a ferocious debate over the years because people have touted LN as the solution for BTC’s congested mempool, even though the network is very much in its infancy.

Just recently we reported on the owner of Shitcoin.com, Andreas Brekken, when he initially freaked everyone out with a couple hundred grand worth of BTC sitting within his LN node. Both the BTC and Bitcoin Cash (BCH) communities had discussed the subject heavily during the first few days, and Brekken’s story made headlines in multiple news publications and podcasts. Since then Brekken wrote four reviews about his experience being the largest node on the Lightning Network. In Brekken’s first review “Lightning Network #1 Can I Compile and Run a Node,” the review gives some comprehensive insight to successfully installing and configuring the ‘lnd’ protocol. The author notes that the ‘autopilot’ feature helps establish a connection and provides funding to the payment channels.

Brekken explains there are a few reviews online that detail the Lightning Network’s probability of finding routes, but people who experience issues may be making a simple error. Furthermore, even though the installation process took a lot of time because it requires compiling a BTC full node installation, Brekken details the process was fairly simple to configure.

“Writers critical of Lightning Network claim the probability of finding routes between two random nodes is very low for amounts over $10. I suspect this is because they are choosing random nodes and not peering properly,” Brekken explains.

Compiling, installing, and running Lightning Network Daemon, lnd, was straight forward. I look forward to using payment channels for sending and receiving bitcoin.

In part two of Brekken’s review, he says maintaining a payment hub is becoming stressful and routing doesn’t make that much money. “When I started writing the review the total capacity of the Lightning Network was slightly over 20 BTC (around $130,000) — I decide to shake things up,” Brekken notes. “Reactions to my experiment on social media are mixed. The increase in capacity of the Lightning Network is celebrated by some.”

A Look at What Its Like to Operate the Lightning Network's Largest Node
Brekken’s Shitcoin.com node held 35.24 BTC.
“My Lightning Network node has established over 200 payment channels with 250 peers. The node capacity is exceeding 40 bitcoin. The month_fee_sum comes to 4289 satoshis, or 0.00004289 bitcoin ($0.31). I also wonder how any payments have been routed,” he adds.

The node has routed 260 payments for other users, averaging a profit of $0.0012 USD per transaction. I doubt that this will cover the costs of running the node, but leave the node running for now.

LN Impractical Even for Highly Technical Users
Brekken’s third review, called “Lightning Network #3 Paying for Goods and Services,” shows his experiences sending payments through the network. First Brekken heads over to a website called Satoshitweet to pay a small microtransaction for a posted tweet on the platform. However, after clicking the ‘Pay 2020 satoshis’ to tweet button he gets an error. “I click the button a few more times — The error remains the same — I look in the Google Chrome network inspector and SatoshiTweet is returning a generic 500 Internal Server Error response.”

The review then discusses trying to use an LN-based dice game called ‘Lightning Spin’ but Brekken has issues with the site glitching and invoices changing rapidly. After resetting his browser and getting a stable invoice Brekken sends some funds. “The payment will be sent through two hops and pay 1800 msats (0.00000002 BTC or 0.000135 USD). Back in the web browser the spin has been detected and I have won 400,000 sats (0.004 BTC or $30 USD).”

After playing around with Lightning Spin, Brekken tests out various other LN web portals like the Blockstream store, Bitrefill and Satoshi’s Place while experimenting with both the Eclair and Zap wallets. Minus an order for Reddit Gold on the website Bitrefill and Brekken’s win on Lightning Spin, most of the attempts had errors. Brekken concludes in his third review:

Sending payments using the Lightning Network is cheaper than the regular Bitcoin network, but suffers from routing errors and wallet bugs that make it impractical even for highly technical users.

Stressing Out About a Possible Lightning Network Exploit
Brekken wraps up his final review in his Medium article called, “Lightning Network #4 What Happens When You Close Down Half of the Lightning Network Capacity?” Brekken says operating the largest nodes within LN was fun, but also “terrifying” at times. Brekken’s node has routed 389 payments in total which added up to a profit of USD$0.34 cents. But a portion of the funds didn’t come from routing as Brekken notes, “I suspect the increase is mostly from the recent increase in bitcoin’s price.” Brekken also tries to close the connected channels manually but ran into some more errors making some channels unable to close.

So Brekken ‘force closed’ all his channels unilaterally which locks up his funds until a predetermined amount of time ends. “The amount of time the funds are locked up depends on the channel policy — This policy is negotiated when the channel opens. Most channels will release the funds to me in between 1440 and 20180 minutes,” Brekken emphasizes.

The Shitcoin.com owner concludes his fourth review by saying he looks forward to trying LN when it matures more and says that leaving funds on the network can be trying.  

“Running a large Lightning Network node has been quite stressful — An exploit such as we saw with heartbleed could allow an attacker to drain all funds from the node while I’m sleeping. It’s time to end the experiment,” Brekken concludes.  

Operating the largest node on the Bitcoin Lightning Network has been educational, frustrating, fun, and at times terrifying. I look forward to trying it again once the technology matures.
