What is Dogecoin? How a joke became a meme coin

Dogecoin is a cryptocurrency that began as a joke in December 2013, named after an internet meme of a Shiba Inu dog. Underneath the joke it is a working proof-of-work network, built from the same family of code as Bitcoin, with blocks every minute and a fixed 10,000 new coins per block forever. That makes it the first well-known meme coin, and what happened to its price shows what drives meme coins in general.

In short

• Dogecoin was launched on 6 December 2013 by two software engineers who thought crypto was taken too seriously.
• Technically it is a Bitcoin-style network using the Scrypt puzzle, with one-minute blocks and no maximum supply.
• Its price has moved mostly with attention, community and celebrity posts rather than with use, which is the defining trait of a meme coin.

Where did Dogecoin come from?

The "doge" meme was a 2010 photo of a Shiba Inu named Kabosu, captioned with scraps of broken English in multicolored Comic Sans, such as "such wow". In late 2013, as Bitcoin and a crowd of imitators were drawing attention, Billy Markus, a programmer, and Jackson Palmer, who worked in marketing, combined the meme with a copy of an existing coin's code and launched Dogecoin on 6 December 2013, according to the project's own history. They meant it as a parody of crypto's seriousness.

It caught on fast. The same history says that within two weeks Dogecoin carried more daily transactions than Bitcoin, mostly small tips sent on forums such as Reddit. In 2014 the community raised 26.5 million dogecoin, about $30,000 at the time, to send Jamaica's bobsled team to the Winter Olympics in Sochi. Both founders left the project's development that year, and a volunteer team took it over.

How does Dogecoin work?

Dogecoin works like most early cryptocurrencies: a public ledger of transactions, kept by nodes, extended by miners who compete to solve a puzzle. That is proof of work. The puzzle is Scrypt, the same one Litecoin uses, rather than Bitcoin's SHA-256. Its code descends from Litecoin through a short-lived coin called Luckycoin, and its README describes it as adapted from Bitcoin Core.

Three choices set it apart from Bitcoin:

• Faster blocks. A new block arrives about every minute, against Bitcoin's ten, so payments confirm sooner.
• No cap. Early rewards were random and then halved every 100,000 blocks, but from block 600,000, reached in early 2015, every block pays a permanent 10,000 dogecoin, according to the project's FAQ. There were about 100 billion coins by then, and the number keeps growing.
• Merged mining. Since block 371,337, in 2014, miners of Litecoin can mine Dogecoin at the same time with the same work, a design called merged mining (Tari Labs University). Many in Dogecoin's community credit it with saving the network from a 51% attack, in which one miner gathers most of the computing power and can rewrite recent blocks.

What does "no supply cap" actually mean?

It is easy to read "no cap" as "unlimited inflation", but the arithmetic is gentler. Dogecoin adds a fixed number of coins each year, so the percentage rate falls as the total grows.

At one block a minute, 10,000 coins a block adds 10,000 × 60 × 24 × 365 = 5.256 billion coins a year, if blocks arrive exactly on schedule. As a share of the coins already out, that is:

Coins already in circulation	New coins a year	Yearly growth in supply
100 billion (about where it stood in 2015)	5.256 billion	5.3%
150 billion	5.256 billion	3.5%
200 billion	5.256 billion	2.6%
300 billion	5.256 billion	1.8%

The rate never reaches zero, unlike Bitcoin's, whose new supply stops around 2140 under its halving schedule. Supporters say steady issuance suits a coin meant to be spent and tipped rather than hoarded, and it keeps paying miners. Critics say it makes Dogecoin a poor store of value. Either way, the supply rule is not what moves its price.

Why did celebrity posts move its price so much?

A meme coin is a token whose value comes almost entirely from attention and community, not from cash flows, a product or a technical edge. The US Securities and Exchange Commission's staff described meme coins in a February 2025 statement as crypto assets inspired by internet memes, characters or trends, whose value is driven by demand and speculation, more like collectibles, and whose prices tend to be highly volatile.

With nothing else anchoring the price, the most powerful input is how many people want it this week. In early 2021, a wave of social media hype, including posts by Elon Musk, drew a rush of new buyers, and Dogecoin's price rose many times over within months before falling back by most of the gain. The same pattern has repeated with each meme coin that followed, often faster.

Meme coins resemble earlier manias like the dot-com bubble in that a good story outran any way to value it. They are also a favorite vehicle for fraud: a new meme coin can be created in minutes, hyped, and sold by its insiders into the buying, a "pump and dump". Scams that pose as investment platforms, such as pig butchering, borrow the same promise of fast gains.

Still argued

Fans see Dogecoin as a friendly, cheap way to send small amounts and as proof that community can give a coin lasting value; it has outlived most coins launched in 2013. Skeptics see a coin with no cap, little use beyond trading, and a price that follows attention. Both describe parts of the record. This note explains what Dogecoin is; it isn't advice to buy or sell it.
