If youre a fan of the Showtime drama Billions but having a tough time following the current seasons cryptocurrency story lines, youre not alone. Not only do the actors have trouble keeping up with the series twists and turns, even those who work in the financial sector dont necessarily understand crypto mining, a subject that pops up several times in season five. Half the people in finance couldnt explain what mining is to you, says New York Times best-selling author Ben Mezrich, who joined the Billions writers room this season as a consulting producer. A large percentage of them have no idea, because its complex.

As the writer of Bitcoin Billionaires and The Accidental Billionaires: The Founding of Facebook: A Tale of Sex, Money, Genius and Betrayal the latter of which was adapted into the movie The Social Network Mezrich is a natural fit for the Billions team. His expert knowledge of cryptocurrency has provided the series with an opportunity to further explore this once-dark, underground area of finance. He also wrote this seasons third episode, which has Gordie Axelrod (Jack Gore), son of billionaire Bobby Axe Axelrod (Damian Lewis), running his own crypto-mining operation.

From the safety of his home in Quechee, Vermont, where hes riding out the COVID-19 pandemic, Mezrich was kind enough to guide Vulture through the intricacies of these esoteric plotlines. The result is this useful explainer for those of us who love Billions, but are still lost when characters like Axe and Chuck Rhoades (Paul Giamatti) start talking Bitcoin and blockchain.

Its a form of electronic money that sparked interest in recent years due to its skyrocketing prices. Its money that goes instantly from one person to the other, and theres no middleman, says Mezrich. A can be sent from person-to-person via their phone, just like a text.

The most well-known example of cryptocurrency is Bitcoin, which was created in 2009. But theres almost an infinite amount of cryptos at this point, says Mezrich.

This is the process of how the money is transferred from person-to-person. Because cryptocurrency doesnt use banks, miners are the ones who verify each transaction. Say I send you a Bitcoin, says Mezrich. The way that transaction is verified is, miners are working on computers attached to the network, which are doing these mathematical equations. And these equations, when theyre solved, they verify our transaction, and as a reward, the miner gets a certain amount of Bitcoin.

The process is very much like a contest, because all these different miners are competing to solve the equation, with the winner getting the Bitcoin. Mezrich likens mining to the race for the golden ticket in Charlie and the Chocolate Factory: You open all these wrappers and one of them is gonna have a piece of gold in it. But you dont know which one, and so youre incentivized to get all the [chocolate bars] you can. This is what these miners are doing: Theyre just continually trying to solve these equations. Because whoever solves it first, gets the golden ticket the Bitcoin.

You probably remember this term being bandied about by Chuck last season regarding mobile voting. A blockchain is a digital database containing information that can be simultaneously used and shared within a large, decentralized, publicly accessible network, according to Merriam-Webster.

Because its where all crypto transactions are logged. If I send you one Bitcoin, says Mezrich, that transaction is logged onto the blockchain. And the way it becomes verified is by these miners. Theyre the ones who essentially put these equations onto the blockchain.

Those guys are miners, and they were dealing with the aforementioned mathematical equations, which are not only very complicated, but require enormous amounts of computing power, says Mezrich. If you walk into a crypto mine, its computer after computer after computernot unlike what was inside the sketchy warehouse that served as the miners base in the episode.

The miners were drawing power from a town in upstate New York, which is where the legal issue comes into play. The problem is, if youre mining Bitcoin and you need to draw tons and tons of power, eventually, that cost can be more than what youre earning, explains Mezrich. So miners are always trying to find cheaper electricity. Enter the small town in question: The town gave the miners priority over their electrical power. By doing that, the miners are saving a lot of money, and they make a kickback deal with the town to get cheap electricity, but the way they get the cheap electricity is its being routed to them rather than the rest of the town, causing brownouts.

Axe is involved because hes the leader of a consortium that combined its resources to fund this operation. In the general scheme of things, its not a bring-down-Axe crime, but its certainly a way in [for Chuck], says Mezrich. So for now, there isnt enough evidence connecting him to this venture for Chuck to take legal action yet.

Instead of just mining Bitcoin, Gordie was mining a lot of different cryptos at once out of his prep-school basement. The way Axe describes his sons scheme to Wags (David Costabile) Its the smart way to do the stupid thing he was doing isnt much different from how Mezrich explains it. With multi-mining, you have a better chance of making money and you have less of a chance of getting caught, because youre hacking electricity on a smaller scale.

He was trying to pull down enough electricity to power a whole bank of crypto mines a bunch of computers to run all these calculations, says Mezrich. In so doing, he ended up short-circuiting and causing a massive power-grid failure.

Mezrich admits that Billions took a bit of dramatic license here.

He absolutely committed a crime by tapping into his schools (and the towns) power grid. If he had had his own power source, if he was just working at home with that, it wouldnt be illegal, says Mezrich. As for the actual crypto mining, Mezrich used Gordies tradition-bound prep-school headmaster as a stand-in for those who still see Bitcoin and other cryptocurrencies as the dirty part of the finance world. The mainstream has still not accepted it, he says. The headmaster would be one of the types who sees [Gordies behavior] as an affront to the men of honor that these kids are supposed to become.
