People Can Now Preorder the Finney Smartphone

Sirin Labs has launched its flagship product the Finney phone, a mobile device named after the late bitcoin developer Hal Finney. News.bitcoin.com originally reported on the Finney phone back in May when it was revealed that Foxconn, the company that manufactures iPhones, helped Sirin Labs produce the new blockchain mobile device. This week, Sirin Labs announced the phone can now be purchased on the company’s official website for $999 and the product will also join the Amazon Launchpad program in January.

According to the phone’s specifications, the mobile device has a 6-inch touchscreen display and is powered by an octa-core processor with 6GB of RAM. Finney runs on an operating system called Sirin OS, which is a fork of the Oreo software Android 8.1. The cryptocurrency features within the phone can be seen by using a second touchscreen that’s attached to the phone’s body. Sirin has explained that this is how the Finney device’s extra layer of security works because when the pop-up screen is used, all actions performed by the Sirin OS are encrypted. The Finney creators state that the second touchscreen has a firewall between the main operating system and claims the process makes the phone much harder to compromise. The cryptocurrency side-software has a program known as token conversion service (TCS) so the mobile phone’s owners can swap coins like BTC and ETH.

Additionally, the phone has a 12-megapixel rear camera and a selfie camera with a design that’s very similar to the Solarin phone. The Solarin is another design created by Sirin Labs, but the Solarin carbon titanium 128GB version is a whopping $13,800 plus tax. The Finney model also comes with 128GB of storage and can be expanded upon with a micro-SD card. Lastly, the mobile device accepts a nano-SIM and can connect to traditional Bluetooth, NFC, and wifi networks. “Sirin Labs is also looking for strategic OEMs to implement Sirin OS in additional consumer devices,” the Barcelona-based company explained on Thursday.

The Finney Smartphone Has a Competitor

The new Finney cellphone is not the only mobile device specifically designed for blockchain security. Taiwanese consumer electronics manufacturer High Tech Computer Corporation (HTC) is also producing a cryptocurrency-centric phone. HTC has said the new “blockchain-powered” product will use a modified version of the Android operating system. The HTC Exodus 1 is also available for preorder on its website by reserving the phone with either BTC or ETH funds. At the moment the HTC Exodus 1 is priced at around 0.15 BTC or roughly $600 at the time of publication.

With the new Finney phone launch, Sirin Labs has explained that the company is planning to open two flagship concept stores so the public can get an inside glimpse at the blockchain mobile device. According to the Finney manufacturer, the first concept store will open in London in December of this year and then another location in Tokyo in January of 2019. Sirin Labs emphasized during the announcement that the London store will also act as a blockchain academy for individuals in the community looking to learn about cryptocurrency solutions.

New bitcoin Cash Opcode Shows an Onchain Game of Chess is Possible
New bitcoin cash opcode shows an onchain game of chess is possible

Since the recent bitcoin Cash (BCH) upgrade, the protocol now has some newly added features like the re-enabled opcode OP_Checkdatasig. After the implementation, a few developers have been experimenting with the opcode and have developed concepts such as “spending constraints.” Moreover, in another instance, a programmer recently used the opcode to create an onchain chess game on the BCH blockchain.

Spending Constraints

Over the last week, BCH supporters have been slowly trying to move away from the recent blockchain split and concentrate on building. One example of this is a recent proof-of-concept written by a BCH developer called Pein Sama, which uses the opcode OP_Checkdatasig to explore new capabilities. Sama details that before the Bitcoin Cash upgrade, the BCH script was limited to someone specifying that one could spend a coin but at the time there was no way of adding constraints on how it could be spent. The developer then demonstrates how it is now possible to create spending constraints with the new BCH coding language called Spedn.

After Sama published his idea, the BCH community discussed the concept of spending constraints and other ideas like covenants as well. A few people specifically discussed the end of Sama’s documentation, which says the concept could produce things like OP_Return based tokens that are “miner enforceable.” The programmer explained that it could be argued that OP_Group is a cleaner way of adding native tokens, but he didn’t have a strong opinion on the matter. “My article is just exploring the new land,” the developer noted on the Reddit forum r/btc.

A Game of Chess

New bitcoin cash opcode shows an onchain game of chess is possibleNot long after the published post about spending constraints with the opcode OP_Checkdatasig, a developer named Tobias Ruck was inspired by the opcode exploration and designed a chess game with the new feature. Because chess rules are deterministic, they can use a third party to help enforce the rules of the game and that’s where OP_Checkdatasig comes into play. By utilizing the “nifty spending constraints” originally published by Sama, Ruck shows how the concept can be applied to a game of chess.

“The good thing about chess is that its rules are deterministic, so no need to throw dice or do some cryptographically secure pseudo-random number generator magic,” Ruck explained in his recent blog post. The developer continued by describing the benefits of using OP_Checkdatasig as trusted oracle within a game of chess by stating:    

If Kasparov were to challenge Anand for a round of chess, they might trust some third party (referee) or even each other to enforce/follow the rules, but if they are anonymous people on the internet playing for not insignificant amounts of money, it would be good if the rules of the games didn’t require a trusted third party.   

In his blog post, Ruck further elaborated how chess can be played with the new opcode and implemented the concept into a Python environment. This is where Ruck adds the “juicy parts” of the code, like operations such as “apply_move,” “white_has_won,” “black_has_won” and “is_stalemate.” After messing around with the program some more, Ruck eventually runs into the situation where a stalemate occurs and the game ends as a draw. Ruck explains that if the game was being played for a 1,000 satoshi incentive “neither white nor black can get any of the 1,000 satoshis, except if they agree to a draw and split the money.”

The chess game creator also explains there are a few issues that could arise, like someone not making a move and the 1,000 satoshis getting locked into the blockchain forever. But Ruck says that a lock time could be added and the game will end after a certain amount of time has passed. Overall, Ruck’s chess concept is extremely raw and basic but shows how the opcode could be applied to all types of decision-based games. In conclusion, the developer’s blog post states that he hopes he was able to convey the idea of a chess game using OP_Checkdatasig as trusted and autonomous referee.

Building a Turing Machine on Top of the bitcoin Protocol

After publishing the onchain chess game and while experimenting with the new opcode, Ruck realized that it is possible to build a Turing machine on top of the bitcoin protocol. The researcher published a followup post, which shows how he simulated an old programming language using the BCH script.

“A simple way to show Turing completeness is by simulating a Turing machine,” Ruck details in his second blog post. “For that, we’ll pick a derivative of Smallfuck, an esoteric programming language, which has been shown to be Turing complete  If we can simulate that on bitcoin, we know it’s Turing complete,” the programmer adds.

After showing how it can be done using the new opcode OP_Checkdatasig, Ruck emphasized that the bitcoin protocol is Turing complete giving the technology a myriad of use cases. Ruck further adds that if developers optimized the code a “fully fledged and operational bitcoin virtual machine (VM)” could be built. Ruck also adds that people who claim Craig Wright’s propositions “were right about OP_Checkdatasig introducing loops in the bitcoin script are just wrong” and this is “false” information. “The idea that you could call another transaction by checking a signature is just ludicrous,” Ruck’s blog post states. In order to keep loops spinning, Ruck’s details that the program has to be fed with more satoshis per loop in a similar fashion to the Ethereum network’s gas limit.

This trading volume is moderate to heavy. The weekly price trend is mixed.

$ETH Remains Third Rank
Two weeks ago we saw $ETH slip to third in market cap to $XRP (again), and this hasn’t changed. Ripple has widened the gap and today is printing more than $2.8 billion more in market capitalization. Coinmarketcap pegs $XRP at $14.6 billion with ether weighing in at $11.8 for a difference of $2.8 billion. The flip is not irreversible but the fundamentals for $XRP appear to be much healthier than those of $ETH.

Lowest Price Since Spring 2017
The last time we saw ether at such a bargain it was May 19 of 2017, the price was $113.41, and ether was on its way up. That rally saw a peak of $410.75 (Coinmarketcap). However this time the market has been bearish since the week of May 06 2018. That’s half a year of bear market:

Bear Market Since Spring of 2018

What to Expect?
With half a year of bearish movement it might be easy to postulate more of the same. The six hour chart default MACD is showing strong buying pressure on an extended length of time:

Six Hour Chart MACD

The RSI on the one day chart is printing 41.61 which is well within the neutral zone (between 30 and 70).

The short term EMA on the four hour chart has dipped below the medium term EMA, signalling a weakening of the $ETH position.

Volume is down, although still moderate, and price is in the red over a two day period on the one day chart. There appears to be less contention over the current price, and not as much enthusiasm to send it higher or lower.

$ETH Weekly Price Trend
Tap/click to zoom:
Sirin labs launches blockchain-centric ‘finney’ smartphone

The weekly trend is mixed. This is different from up or down. The weekly range is between $126.80 and $102.36. Within the week we’ve seen four daily candles of red, but three of green. Seven days of oscillation within a $24.44 scope is beginning to look like a sideways condition. The price is softening over the last two days, but staying within the weekly range.

The key ten day resistance line is $137. If ether can decisively break this resistance then good things could happen.

The yearly 2018 low of $102.36 was set three days ago on November 26 2018. This sits just below a critical support level at $104.53. If ether erodes below this key support then fresh price declines are likely.

View
If ether can decisively break $137 key resistance then a continuing upwards movement is possible.

If ether erodes below $104.53 key support then fresh price declines are forecast.

The technicals suggest a weakening $ETH price but within the existing narrow weekly range.
