If you think blockchain technology is boring, this Twitter user is out there to prove you wrong.

Lightning K0ala has created an online graffiti board , called satoshis.place, to show the power of Lightning Network (LN) in processing micro-transactions.

For those who do not know, Lightning Network is a layer that sits on top of Bitcoin’s blockchain to make the transactions cheaper and faster.

While the technology is still in its nascent stage, it is often touted as a solution to Bitcoin’s scalability problems. Its total network capacity crossed $150,000 in April. In fact, at one point in March, it had more active nodes running than Bitcoin Cash (BCH), a Bitcoin hard fork that also claims to solve Bitcoin’s scalability worries.

But naturally, users were more interested in doodling penises on the board. In fact, the website keeps track of dicks drawn — 106 at the time of this writing.

If you are interested in doodling your own penis — I mean, if you are interested in testing micro-transactions with LN yourself, here is how it works:

There are one million pixels on the canvas, and each pixel costs one satoshi to paint. You can choose to draw whatever you want and wherever you want. Based on how large your painting is, you pay the equivalent amount in Satoshi (1 BTC = 100 million Satoshi). If you want to paint the entire canvas red, it will cost you $67.39 as per the current BTC price (My piece of art cost me $0.04).

We reached out to the founder of satoshis.place to understand his vision for the app.

“I created satoshis.place to explore the application of micro-transactions in the context of multiplayer games. I also just wanted to mess around with running a Lightning node figuring out how this stuff works,” Lightning K0ala told Hard Fork. “Things have been amazing so far, it’s been a laugh trip for the last three days watching people draw on the board and comment on social media. We’ve got a nice little group on Telegram forming where people post suggestions and I can gauge what stuff should be fixed or improved.”

Did he anticipate that so many people would be using the board to draw penises? “No,” he answers. “I did not anticipate how creative people would get with penises. It’s… majestic.”

He clearly underestimated the power of penises over blockchain.

Even Bitcoin developer, Jameson Lopp, took to Twitter to share his favorite penis doodle from the board. It is this one:

$1K worth of Bitcoin is hidden inside this French street art

To celebrate the tenth anniversary of the Bitcoin genesis block , crypto-inspired graffiti artist Pascal Boyart has hidden $1,000 worth of Bitcoin inside a new mural to be found somewhere in Paris.

The fresco is named after (and inspired by) the famous Eugène Delacroix artwork “La Liberté guidant le peuple” (Liberty leading the people), painted in the early 19th century.

Boyart has updated the piece to pay homage to the Gilet Jaunes, or Yellow Jackets – the French protest movement fighting for reprieve from an ever-increasing cost of living and the apparent indifference of president Emmanuel Macron.

The mural was painted at an undisclosed location in central Paris. Boyart told Reddit that in order “[t o solve the puzzle [entirely], you must be [physically] in front of the mural,” but added it’s possible to solve “part” of it even if you aren’t in France.

Understandably, Boyart has been pretty cagey about sharing any more details, in case he gives away too many hints.

The original Delacroix piece was painted to commemorate the July Revolution, which culminated in the abdication of King Charles X.

It shows a woman, known as Marianne, leading a rag-tag group revolutionaries armed with rifles, pistols, and swords. It has since become synonymous with anti-monarchic sentiment.

Boyart’s reimagining replaces the firearms with spray-paint and sticks, while giving the new revolutionary army gas-masks.

Since the Gilet Jaunes protests began in November, police have repeatedly used water cannons and tear-gas to disperse activists.

This piece is the latest in a series of prominent Bitcoin-infused artworks from Boyart, who told Hard Fork he has plans to create a new mural every six months, using BTC donations to fund his work.

Last year, the French artist infamously added a QR-code to one of his giant artworks, allowing him to field more than $1,000 in Bitcoin from passersby.

The contentious Bitcoin Cash hard fork is here, now the hash war begins

Following a months-long internal strife in the community, the contentious Bitcoin Cash (BCH) hard fork has finally taken place.

The Bitcoin Cash blockchain is now split in three separate networks, each with its own set of rules and governing principles: one developed by Bitcoin-ABC, one developed by Craig Wright’s blockchain research unit nChain, and one developed by Bitcoin Unlimited.

While the network has technically split in three, the main tension resides between the implementations proposed by ABC and SV; Unlimited’s proposal simply aims to reconcile those two.

While ABC’s version aims to support smart contracts, oracles, and other features that will allow developers to build applications on top of Bitcoin Cash, SV intends to up the maximum block size from 32MB to 128MB to allow for smoother scalability and better confirmation speeds. (We’ve yet to see if those approaches can effectively solve the problems they aim to solve.)

The issue is that those two different implementations are fundamentally incompatible with each other – which is why the Bitcoin Cash network has now been split into separate blockchains, each spurring a new cryptocurrency: BAB (for ABC implementation and BSV (for the SV implementation).

What’s the real Bitcoin Cash?

It remains to be seen which chain will emerge as the winner in the long run, but for now – SV is in the lead, earning the support of nearly 75 percent of the community’s mining power. Unlimited and ABC are in close contest for the second place.

Now, it’s only a matter of time before one of the three approaches crops up as the dominant solution – and along with that, secures its position as the new “real” Bitcoin Cash.
