Developer Demos Smart Card That Produces Bitcoin Cash Signatures

Software engineer Tobias Ruck has revealed a project he’s been working on that allows a smart card to produce valid BCH signatures. Ruck tweeted about his experiment to the crypto community and Bitcoin Cash proponents showed their excitement about the future of offline payments.

Harnessing Offline Bitcoin Cash Payments

For quite some time the developer Tobias Ruck has been experimenting and developing concepts that help bolster the BCH ecosystem. reported on Ruck last year when the programmer demonstrated how an onchain game of chess is possible. After the opcode OP_Checkdatasig was implemented to the BCH chain, Ruck designed a chess game with the new feature. This spring, as the Simple Ledger Protocol matured, Ruck unveiled an onchain SLP token auction console. More recently, Ruck published a video about a new transaction version for the BCH chain called Nimbus. According to Ruck’s demonstration, the transaction version could unleash sophisticated smart contract potential on the BCH network. Moreover, it’s possible a cryptocurrency stablecoin like Dai could be created on the BCH network. Throughout the video, Ruck stresses several times that the Nimbus concept required a rule-set protocol change.

Developer Demos Smart Card That Produces Bitcoin Cash Signatures

During the second week of October, Ruck showed the community he was experimenting with protocols that facilitate offline transactions. That week the programmer published another demo that showcased a bitcoin cash wallet tool called Essentially, the concept provides individuals with the ability to send and sign a transaction without internet service. Then on November 11, the programmer tweeted that he developed “a smart card that produces valid Bitcoin Cash signatures.”

“Who would love to pay with a card — to a phone? Tap took less than a second. Imagine trying to set up shop accepting cards and all you need to do is install an app on your phone,” Ruck stated. The software engineer emphasized that his concept was “still very much unpolished. I still have to make the app build and send the transactions, but once finished — it‘s going to be huge — When scaled up, smart cards could literally be $1 each,” he added.

The Quest for Instantaneous, Offline, and Frictionless Transactions

Ruck’s announcement was celebrated on Twitter, gathering a lot of comments and over 400 likes. On November 11, the front page of the Reddit forum r/btc was also scattered with threads about the smart card that could produce valid BCH signatures. “Use case extends far past payments — How about transparent access records? To doors, to accounts, to events, to anything,” blockchain developer Chris Troutner wrote in response to Ruck’s tweet. “Pay attention to the community that values utility the most,” Bitcoin ABC developer Amaury Sechet tweeted.

Cointext CTO and founder Vin Armani stressed on Twitter that all of the great concepts being produced these days are due to great innovation tethered to the features at the protocol level. “The latest and greatest innovations in BCH are all possible because new capabilities have been added into the protocol, before we developers needed them,” Armani said while re-tweeting Ruck’s smart card demo. “That’s a signal of good decision-making.” Armani added:

This is a brand new way of doing transactions. Something totally novel. For technical details, please check out Tobias Ruck’s further demos/documentation at

BCH developers working on the protocol level have been working relentlessly to bolster the Bitcoin Cash roadmap. Third-party application programmers have also been working with the BCH blockchain and Simple Ledger Protocol day and night creating new and innovative ideas. While some of the concepts never materialize, the concepts can still be left on the shelf for another software engineer to try. For many BCH proponents, zero-confirmation transactions and offline transactions have been a holy grail of sorts. The quest continues because users want payments to be as fast as handing someone cash or the few seconds it takes to swipe a credit card. Ruck’s latest smart card concept may help further this goal.

While Bitcoin’s price seemingly moves without rhyme or reason — collapsing by dozens of percent and embarking on face-melting rallies on a whim — the cryptocurrency market is filled to the brim with fractals.

A brief aside: A fractal, in the context of technical analysis and financial markets anyway, is when an asset’s price action is seen during a different time. This form of analysis isn’t that popular, but it has proven to be somewhat valuable in analyzing Bitcoin.

One recent fractal popularized by a well-known cryptocurrency trader is implying that BTC is going to return to the low-$7,000s in the coming days.

Bitcoin Fractal Implies Retracement to Low-$7,000s

A well-known crypto trader going by “Tyler Durden” on Twitter recently posted the chart below, which shows that a Bitcoin price fractal may be playing out. The fractal has four phases: horizontal consolidation marked by one fakeout, a surge above the consolidation phase, a distribution, then a strong drop to fresh lows.

If the fractal plays out in full, BTC could reach the low-$7,000s again, potentially as low as $7,100. This would represent a 20-odd percent collapse from the current price point of $8,800.

It isn’t only a fractal that is hinting Bitcoin has the potential to visit its lows. As we reported on Saturday, Bloomberg believes that if the GTI Vera Convergence Divergence Indicator flips red, a downtrend could push the cryptocurrency back to $7,300.

Can Bulls Step In?

But again, many believe it is irrational to have such bearish interpretations of the cryptocurrency’s chart at the moment. As reported by NewsBTC earlier, Popular crypto trader Mayne recently noted that the “people waiting for $6,000” are irrational. He quipped that Bitcoin retracing and consolidating after its fourth-biggest bull move in history ($7,300 to $10,500, a 42% gain) is perfectly par for the course, but noted that it’s totally possible we can go lower from $8,800.

The medium-term technicals support this.

Trader and CoinTelegraph contributor FilbFilb found that by the end of November or start of December, the 50-week and 100-week moving averages will see a “golden cross,” which he claims is far more significant” for the Bitcoin market that other technical crosses.

Also, a Bitcoin price model created using Facebook Prophet machine learning found that the leading cryptocurrency is likely to end the year at just over $12,000. What’s notable about this model is that it called the price drop to $8,000 months in advance, and forecasted a ~$7,500 price bottom for BTC.

To put a cherry on the cryptocurrency cake, Crypto Thies observed that when Bitcoin bottomed at $7,300, it bounced decisively off the 0.618 Fibonacci Retracement of the move from $3,000 to $14,000, which correlates with the two-week volume-weighted moving average. He added that summer 2019’s consolidation was marked by Bitcoin flipping major resistances into support levels, implying that a bullish reversal and subsequent continuation is likely possible in the coming weeks.
