Banano: A Meme Coin Fighting Alzheimer's

Somewhere in a closet or a drawer you probably have a laptop you stopped using. It still turns on. It is too slow for anything you care about and too good to throw away. This article is about a way to put it to work: running protein simulations for medical researchers studying Alzheimer’s, Parkinson’s, cancer, and Huntington’s disease, and getting paid in cryptocurrency for doing it.

The coin that pays you is called Banano. It is, by its own description, a meme. It is also a working, feeless, instant cryptocurrency with an eight year track record, a direct family relationship to Nano, and one of the more useful distribution mechanisms in all of crypto. Here is the whole story.

A fork with a sense of humor

Banano launched on April 1, 2018. The date was not a coincidence. Its yellowpaper, credited to “Banoshi Nakanano,” describes it as “the first fork peel of NANO,” and nearly every sentence in the document is a joke that happens to be technically accurate. The network runs on what the yellowpaper calls “Block Lettuce” architecture, which is the block lattice design Banano inherited from Nano: every account has its own chain, consensus comes from Open Representative Voting, and transactions are settled in about a second with no fee. The parent coin’s engineering was borrowed whole. What changed was the attitude.

Banano’s founders looked at the crypto landscape of 2018, a year of initial coin offerings, premines, and whitepapers promising to change the world, and decided to do the opposite. There was no ICO. There was no sale of any kind. The yellowpaper states that “all coins were and are distributed through an ongoing free and fair distribution program,” meaning faucets, airdrops, games, tips, and contests. If you wanted Banano, you did not buy it. You showed up on Discord and someone gave you some, or you played a game, or you solved a captcha, or you let your computer fold proteins.

Every account gets a MonKey, an algorithmically generated cartoon monkey unique to that address, with fur colors, hats, glasses, and tails of varying rarity. The wallet apps are Kalium on mobile and the Banano Stand in a browser. One Banano is a hundred Banoshi. The whole thing is built to be approachable for someone who has never held a cryptocurrency, and to be funny enough that they stick around long enough to learn how it works.

The community that grew up around it has been unusually productive for a joke. It built JungleTV, a shared video platform that pays viewers; a Minecraft integration; cryptomonKeys, a collectible series; tipbots for Discord, Reddit, and Telegram; wrapped Banano that trades on several other chains; and, in 2025 alone, a name system for .ban addresses that opened to public registration. The yellowpaper puts it bluntly: “Behind all the memes and sh*tposting, the BANANO operation has a highly skilled team dedicated community, and it is very, very, legit.”

The Nano relationship

Banano is not a competitor to Nano and does not pretend to be. It is Nano’s code, running as a separate network, with a separate supply, pointed at a different audience. Nano’s philosophy is to do one thing and do it well: be money. Banano’s philosophy is to be a playground where people learn what feeless instant money feels like, with a lower bar and a higher tolerance for experiments. The yellowpaper notes that Banano is more open to adding features like on chain messaging and privacy layers that Nano deliberately keeps out of its core.

The relationship runs in both directions, and Nano users benefit from it more than most of them realize. In March 2019 the Banano team released Natrium, which became and remains one of the most widely used Nano mobile wallets and the one recommended by many Nano sites, including this one. Natrium is a fork of Kalium, Banano’s wallet, built by the same developers. The team described it at the time as “a kind of nice way to give back something from the forked currency BANANO to its mother, NANO.” If you have ever sent Nano from your phone, there is a good chance you were using software written by Banano people.

Nano’s founder, Colin LeMahieu, is quoted in the yellowpaper with what amounts to a blessing: “I think memecoins are hilarious, we have one, we have BANANO, I like those guys!”

Where Banano sits today

It has to be said that Banano’s market presence has shrunk to almost nothing. The coin peaked at about five cents in 2021. In November 2024, the exchange CoinEx renamed its ticker for Banano from BAN to BANANO and, on the same day, gave the BAN symbol to an unrelated meme coin called Comedian. In January 2026 CoinEx announced it would delist Banano after a regular review against its delisting criteria, which weigh factors such as trading volume and liquidity. Mercatox, another long time venue, announced in late 2024 that it was closing, with a withdrawal deadline of December 28, 2024. As of this writing the price trackers show Banano at a few hundredths of a cent, a market value under one million dollars, and negligible tracked volume, with what trading remains happening on decentralized exchanges and on community swap services like Nanswap and banano.trade.

Set against that, the network itself is fine. Nodes are being updated, the wallets work, the faucets pay, the Discord is active, and the community shipped more in 2025 than most projects with a hundred times the market cap. Banano was never designed to be an investment. The team says so at every opportunity. What it was designed to do, it is still doing, and the best example of that is the subject of the rest of this article.

Folding@home, and why your old laptop matters

Folding@home is one of the oldest and most successful volunteer computing projects in the world. It was launched at Stanford University in October 2000 by Dr. Vijay Pande and is now led by Dr. Gregory Bowman at the University of Pennsylvania. The idea is simple: proteins are the molecular machines that make cells work, their shape determines what they do, and when they fold incorrectly the result is disease. Simulating how proteins fold and move takes enormous computing power. Rather than buy a supercomputer, Folding@home breaks the simulations into small work units and sends them to volunteers’ computers all over the world, which run them in the background and send the results back.

The project has produced more than 500 peer reviewed papers on Alzheimer’s, Parkinson’s, Huntington’s, several cancers, antibiotic resistance, malaria, and viral diseases. In 2020, when volunteers rushed to contribute to COVID research, the combined network briefly became the first exaflop computer in history, faster than any single machine on the planet. Nvidia, AMD, Intel, and Microsoft are among its institutional backers.

Any computer can participate. The client runs on Windows, macOS, and Linux. It uses whatever you give it, a modern graphics card if you have one, an ordinary processor if you do not, and it politely gets out of the way when you need the machine for something else. The old laptop in the drawer is exactly the kind of hardware it was built for.

How Banano Miner turns folding into coins

Banano Miner is the bridge. It launched in its current form in April 2019, replacing an earlier version that mined a different cryptocurrency, Webchain, and paid out Banano at a heavy subsidy. The team dropped that kind of mining and replaced it with something they could feel good about: rather than burning electricity on arbitrary hashes, your computer does medical research, and Banano pays you for the research.

The mechanism is tidy. Folding@home lets volunteers join teams and credits points to each member for completed work units. Banano’s team number is 234980. When you sign up at bananominer.com, you paste your Banano address and the site gives you a folding username tied to that address. You install the Folding@home client, enter that username and the Banano team number, and start folding. Banano Miner watches the public Folding@home statistics, sees the points credited to your name, and sends Banano to your address in proportion. Payouts run about every twelve hours once you have completed a couple of work units, and the first one usually arrives within a day or two of starting. The community guide at nanners.cc adds that a minimum of 3000 points is required before a reward is paid. Setting up a free Folding@home passkey, which the project uses to reward reliable contributors, increases your points after your first ten work units.

The numbers behind this are not small. As of this writing, Banano Miner reports having distributed more than 436 million Banano to folders over its lifetime, with 259 people actively folding and more than 10 billion points contributed in September 2026 alone. On Folding@home’s own leaderboard, the Banano team ranks second of all time among tens of thousands of teams, with 4.7 trillion points and more than 35 million completed work units. That is a great deal of real science paid for by a joke coin. Recent payouts visible on the site run from a couple of Banano to a few dozen per person per cycle, depending on hardware.

Banano Miner’s own FAQ is refreshingly direct about what you should expect: “You should contribute to folding@home because you support the work they do, not because you may get paid for it.” The point to Banano ratio is adjusted by the team and is not guaranteed. At current prices the coins you earn are worth very little in dollars. What you get is a wallet that fills up on its own, a MonKey of your own, a community that will happily trade, tip, and play with you, and the knowledge that your spare computer spent the night working on research into diseases like Alzheimer’s.

Setting it up in ten minutes

Get a wallet. Install Kalium from the iOS or Android app store, or open the Banano Stand at thebananostand.com in a browser. Write down the seed it gives you. Copy your address, which starts with “ban_”.

Register the address. Go to bananominer.com, paste the address, and click Start. The site will show you a username to use for folding.

Install Folding@home. Download the client from foldingathome.org for whatever operating system the machine runs. During setup, enter the username Banano Miner gave you and team number 234980. If you want the bonus, request a passkey from Folding@home’s site and enter it too.

Leave it running. The client will fetch work units and process them. On a GPU a work unit might take an hour; on an old processor it may take most of a day. That is fine. Points are credited when each unit completes, and Banano Miner pays on its next cycle.

Check your MonKey. Within a day or two, open Kalium. There will be Banano in it.

That is the whole procedure. No account beyond a wallet, no identity, no deposit, no purchase. A laptop that was going to sit in a drawer is now a small piece of the second most productive team on the most powerful volunteer research network in the world, and it is being paid.

The Highlander view

Banano is what you get when you take Nano’s engineering seriously and take everything else lightly. Its market value has collapsed, it has lost its exchange listings, and none of that changes what it does. Eight years in, it is still handing out coins for free to anyone who shows up, still funding wallets that Nano users depend on, and still paying hundreds of people to run one of the most important distributed science projects ever built.

If you have an old machine and an interest in seeing how feeless cryptocurrency actually works, you could do a lot worse than to spend a night folding. The research is real. The payment is instant. And the monkey is free.
