In , Adam Back invented hashcash, a proof-of-work system that would prove very similar to what Bitcoin uses. This year saw the sudden emergence of two cryptocurrency ideas.

In late , Wei Dai released an essay detailing his idea for "b-money," a cryptocurrency whose exchange reads similarly to what the blockchain in Bitcoin would eventually become. The proof-of-work system creates the currency by solving a mathematical computation, and the transfer of money is broadcast to the network.

That same year, Nick Szabo put out a similar proposal for "Bit Gold. Solving the proof-of-work gets you bits and the last bit of the string is used to create the string of the next transaction, similar to Bitcoin's blockchain.

Those predecessors had tried and failed for two decades prior. Then, in , came Bitcoin. In August of that year, Bitcoin. Just a few days into , the first-ever block of Bitcoins, known as the Genesis Block, was mined. By Jan. Nakamoto released the second version of the software in December. With an exchange rate established, it was only a matter of time until someone attempted to make an actual purchase with Bitcoins. In May of , it happened. This still valued a single Bitcoin as a fraction of a penny, but with a purchase made, intrigued parties saw potential in the product.

A couple of months later, Bitcoin's value finally broke the penny threshold. A pivotal year for the exchange of Bitcoin, fittingly the first Bitcoin exchanges popped up in as well - Bitcoin Market in February, and Mt.

Gox in July. Mining pools are where several miners combine resources to get Bitcoin. Not that it was all ups for Bitcoin. Someone spotted a vulnerability in Bitcoin's protocol in October that allowed for transactions without proper verification and exploited it, generating billion BTC. The transaction was soon erased and the vulnerability fixed. Bitcoin began receiving press - both good and bad.

TIME Magazine published an article on Bitcoin for the first time, but the same year there was also an article on Gawker detailing Silk Road, the dark web drug market where Bitcoin was frequently used as payment. Also in June, Mt. Gox dealt with a serious security breach that compromised tens of thousands of accounts and their Bitcoins.

It would not be the first security issue Mt. Gox would deal with. Still, Bitcoin was becoming an entity that more and more of the public knew about and interest in the cryptocurrency grew. This led to a rise in altcoins, other forms of cryptocurrency whose developers were either trying to improve upon Bitcoin or had created the digital coin for a different purpose.

In , Litecoin -- now the seventh-largest cryptocurrency by market cap -- debuted. And then A few things of note happened, like Crypto exchange Mt. Gox going bankrupt and shutting down, but this period mostly saw Bitcoin rising and falling somewhat while failing to reach its high.

It kept ascending. Still, some Bitcoin users were frustrated with the network around this time as well. Bitcoin Cash is now the fifth-largest cryptocurrency by market cap. Still, for the remainder of Bitcoin was on an upswing. More and more people and companies began chasing the trend as the price just kept rising.

Unsurprisingly, it wouldn't continue that heady growth. Many sold their Bitcoins while they could, and the price has steadily dropped all year. Need more information on some of the concepts mentioned in the timeline? Here is what you need to know. Proof-of-work is the system Bitcoin's blockchain network uses to create and hash blocks together.

When the computer in a network must use proof-of-work for mining, it needs to solve a complicated mathematical problem. If a computer called a "node" in the network successfully solves the problem, it must then be verified by the other nodes in the network.

If it does, the transaction is verified and completed, and the miner whose node solved it is rewarded with Bitcoins. Proof-of-work is an incredibly controversial method. It's a secure method of verifying transactions, but requires a lot of energy. As more and more people began mining bitcoins , more high-powered mining hardware and graphics processing units GPU were created for people to gain an advantage. This consumes large amounts of energy, and with so many Bitcoin and other cryptocurrency miners out there, many are worried about the environmental ramifications.

Some cryptocurrencies are testing a proof-of-stake method, which consumes significantly less power. It remains such a mystery that some think it's more than one person, doubting that one single person could create something as comprehensive as the Bitcoin network. Still, others have floated the possibility of it being one person, and there are plenty of theories as to who that one single person could be.

None have been verified. Who are the people that some people think could be Satoshi? Some of them have already been mentioned in this article, such as Bit Gold founder Nick Szabo, whose ideas were remarkably similar to that of Bitcoin.

Others think it may have been Hal Finney, a notable developer and the person Nakamoto sent Bitcoins to in the first ever Bitcoin transaction all the way back in One person is speculated as Satoshi because he tried literally saying he was. That person was Craig Wright, an Australian businessman who not only publicly claimed to be Satoshi Nakamoto but promised he would provide proof of it.

So far, he has not provided this proof. At one point in Bitcoin's history, it could be argued that Mt. Gox, a Tokyo-based Bitcoin exchange, was the largest exchange.

But by , it was gone. Gox was plagued with security issues that would become its downfall.
