Bitcoin Puzzles: Hiding Cryptocurrencies in Plain Sight

Since the inception of bitcoin and other cryptocurrencies, visual puzzles that contain digital asset rewards have been very popular. This week a Reddit user named ‘u/cryptogreetings’ posted a cryptic picture online that contained a puzzle with a 1 BTC prize. Since the image was published online no one has been able to crack it so far as the public address can be seen here. The picture is black and orange and white with a bitcoin symbol and many words, and numbers strewed across the image. The creator says if no one can crack it in a week they will publish some hints to help people out.   

“This work is comprised of Satoshi Nakamoto’s famous whitepaper words, scaled by Log N. Disparate ideas inspired Satoshi to create a solution to revolutionize modern socio-economics and industry,” explains the Reddit user u/cryptogreetings.  

The work reflects on the elements that brought this technology to life, and challenges the underlying security model. Hidden in plain sight lies something more: a treasure hunt. 1 BTC is concealed within the work.

As long as cryptocurrencies can be hidden people will always try to solve these puzzles using techniques like uncovering obscure clues, utilizing steganography and cryptography. People have also stored puzzles within the digital asset’s network as well as one user in 2011 wrote a paper describing a way to implement steganography inside the Bitcoin Core (BTC) network. “That is, storing hidden messages inside the network, that would be available only to those who knew where (and how) to look,” explained the creator and his paper’s summary.

More Whales, Bans, and an Optimistic Cookie Monster: This Week in Crypto

Let’s go over what happened in crypto last week.  Price Watch: Bitcoin Price is down 1% this week after dropping around $1,000 last week. The drop comes in stark contrast to what some high-profile analysts had predicted. Investors have been waiting patiently to regain the all-important $10,000 support level. Ethereum is up 5% this week after being down … Continued

With at least $1.3 billion invested globally in 2018, VC funding for blockchain blows past 2017 totals

Although bitcoin and blockchain technology may not take up quite as much mental bandwidth for the general public as it did just a few months ago, companies in the space continue to rake in capital from investors.

One of the latest to do so is Circle, which recently announced a $110 million Series E round led by bitcoin mining hardware manufacturer Bitmain. Other participating investors include Tusk VenturesPantera CapitalIDG Capital PartnersGeneral CatalystAccel PartnersDigital Currency GroupBlockchain Capital and Breyer Capital.

This round vaults Circle into an exclusive club of crypto companies that are valued, in U.S. dollars, at $1 billion or more in their most recent venture capital round. According to Crunchbase data, Circle was valued at $2.9 billion pre-money, up from a $420 million pre-money valuation in its Series D round, which closed in May 2016. According to Crunchbase data, only Coinbase and Robinhood — a mobile-first stock-trading platform which recently made a big push into cryptocurrency trading — were in the crypto-unicorn club, which Circle has now joined.

But that’s not the only milestone for the world of venture-backed cryptocurrency and blockchain startups.

Back in February, Crunchbase News predicted that the amount of money raised in old-school venture capital rounds by blockchain and blockchain-adjacent startups in 2018 would surpass the amount raised in 2017. Well, it’s only May, and it looks like the prediction panned out.

In the chart below, you’ll find worldwide venture deal and dollar volume for blockchain and blockchain-adjacent companies. We purposely excluded ICOs, including those that had traditional VCs participate, and instead focused on venture deals: angel, seed, convertible notes, Series A, Series B and so on. The data displayed below is based on reported data in Crunchbase, which may be subject to reporting delays, and is, in some cases, incomplete.

A little more than five months into 2018, reported dollar volume invested in VC rounds raised by blockchain companies surpassed 2017’s totals. Not just that, the nearly $1.3 billion in global dollar volume is greater than the reported funding totals for the 18 months between July 1, 2016 and New Year’s Eve in 2017.

And although Circle’s Series E round certainly helped to bump up funding totals year-to-date, there were many other large funding rounds throughout 2018:

There were, of course, many other large rounds over the past five months. After all, we had to get to $1.3 billion somehow.

All of this is to say that investor interest in the blockchain space shows no immediate signs of slowing down, even as the price of bitcoin, ethereum and other cryptocurrencies hover at less than half of their all-time highs. Considering that regulators are still figuring out how to treat most crypto assets, massive price volatility and dubious real-world utility of the technology, it may surprise some that investors at the riskiest end of the risk capital pool invest as much as they do in blockchain.

Notes on methodology

Like in our February analysis, we first created a list of companies in Crunchbase’s bitcoin, ethereum, blockchaincryptocurrency and virtual currency categories. We added to this list any companies that use those keywords, as well as “digital currency,” “utility token” and “security token” that weren’t previously included in the above categories. After de-duplicating this list, we merged this set of companies with funding rounds data in Crunchbase.

Please note that for some entries in Crunchbase’s round data, the amount of capital raised isn’t known. And, as previously noted, Crunchbase’s data is subject to reporting delays, especially for seed-stage companies. Accordingly, actual funding totals are likely higher than reported here.

The sooner our education system is digitally disrupted, the better

It’s difficult to measure the impact of higher education, either in a monetary sense or otherwise, although a few studies have tried. One recent study, involving 14,780 higher education institutions in 78 countries over six decades, suggested that doubling the number of Universities in a region results in a 4.7% increase in GDP per capita over five years.

Two main reasons were suggested by the authors – a rise in workforce skill levels, and improved research and innovation.

This is a vote of confidence for a higher education model that is coming under increased scrutiny, particularly as the cost of University tuition continues to balloon all over the world. In fact, OECD countries are currently spending an average of 1.6% of their GDP on higher education, up from 1.3% in 2000.

In light of continual increases in the cost of higher education, we must ask whether we might be able to achieve these increases in workforce skill levels via a different systemic path.

Digital Disruption
Recent years have seen the rise of various platforms that host what might fairly be called recreational educational content, such as Udemy, Udacity or even YouTube. These platforms offer opportunities for self-education, and although they may offer courses relevant to many professions, they can’t really be considered competitors to the traditional education system because their courses aren’t recognised by employers.

Tutellus xxx, yyy explains what needs to change in the digital education space:
“The traditional higher education system will only be truly under threat from digital disruption when employers recognise qualifications and courses supplied by digital platforms. This places the burden on platforms to ensure their courses are of sufficient quality”

Tutellus is a startup that is creating a platform with exactly this vision in mind. The Tutellus ecosystem integrates students and teachers with employers and is built on blockchain technology with two native tokens – TUT and STUT. The tokenomic profile of these tokens, as well as the platform’s revenue model, aims to create incentives around the production of students (graduates) that’re truly ready for a given job or career.

Students are financially rewarded for the time they spend on the platform; teachers keep the large majority of the revenue their courses generate as well as a cut off the fee paid by employers to hire one of their students; employers get access to a ready pool of keen, driven candidates.

The Economy and Beyond…

The study mentioned previously, unsurprisingly, showed that more higher education institutions results in a rise in workforce skill levels, which contributes to economic growth.

A more surprising finding of that same study was that an expansion of higher education systems was also associated with a greater prevalence of pro-democracy views among individuals.

Innovations that scale often have unintended consequences, and it’s hard to foresee how easier access to quality education could result in anything less than positive. We can’t tell exactly where things will go but what is clear is, the sooner our education systems are disrupted, the better.

Tutellus has partnered with Cryptonomos to conduct its ICO. The presale began on May, 10, the main sale on June 12, 2018. An early bird bonus of 10% will be made available to early participants.

DISCLAIMER: TUT public sale will not be open to citizens, residents or green card holders of the USA (including Puerto Rico, US Virgin Islands, and any other protectorate of the USA) or other representatives of the USA

Blockchair Feed Reveals Messages Encoded in the BCH, BTC and ETH Blockchains

Blockchair Feed Reveals Messages Encoded in the BCH, BTC and ETH Blockchains

Blockchain exploration service Blockchair has launched a new analytics tool. Blockchair Feed decodes the messages that are written into the BCH, BTC, and ETH networks. The results can be viewed in a real-time feed comprised of messages that range from the banal to the enigmatic.

Feast on a Banquet of Messages with Blockchair Feed

Blockchain explorer Blockchair is widely used by the bitcoin cash and core communities for searching for transactions and checking data pertaining to market prices, dominance, and network performance. It’s also one of the few blockchain explorers that enables users to search for specific words or phrases hidden in transactions. Its latest tool goes a step further and decodes these messages in realtime as they are published on each of the three blockchains.

A sample message decoded by Blockchair Feed

Blockchair Feed provides a fascinating and occasionally bizarre glimpse into the conversations that people are having, sometimes with specific people, and sometimes with the world at large, via their favorite blockchain. Most of the messages that can be viewed in the feed come from the BCH network. That’s largely thanks to the success of micro-blogging social networks such as Memo and Blockpress. Each of these capitalizes on the low fees of bitcoin cash, making it practical to message other users via the OP_Return field. Thanks to the recent upgrade to the BCH network, the size of this field has increased, giving rise to even more possibilities for onchain communication.

Blockchair Feed Reveals Messages Encoded in the BCH, BTC and ETH Blockchains

Of the two social networks, Blockpress has the cleaner UI which is reminiscent of Twitter. After creating a profile, header, and username, users can dispatch short messages that include emojis. Judging by the spate of messages appearing in the Blockchair Feed, however, Memo is the busier of the BCH social networks at present. As previously reported by, people have been encoding messages in blockchains for years. The BTC blockchain, for example, contains six marriage proposals. Now, thanks to the rise of tools such as Blockchair Feed, coupled with services like Memo and Blockpress, reading those messages – and even replying to them – has gotten a lot easier.

Have you tried using Blockpress or Memo yet and if so what are your thoughts on these services? Let us know in the comments section below.

Opinion: The Bubble is Not Bitcoin

Although the market is positive overall, at the time of writing, the sentiment is quite negative. Maybe due to the high expectations over Consensus, which did not create that much demand over bitcoin, at least not as much as it happened during previous years. I understand it’s your money that is at stake and the
