No prior knowledge required! Bitcoin was first described in a 9-page research paper posted online in under the pseudonym Satoshi Nakamoto. The paper, titled Bitcoin: A peer-to-peer electronic cash system , covers a broad variety of topics, such as financial economics transaction costs, trusted third-parties, money supply , network engineering distributed decision making, data routing, cyberattacks , and cryptography , a branch of mathematics interested in establishing secure communications to facilitate peer-to-peer, open, and borderless transactions between users. How many people do you know who have expertise in financial economics and network engineering and cryptography? And this is the primary reason why, until today, bitcoin has remained difficult to understand for most of us.

Bitcoin Crash Course

The cryptocurrency was invented in by an unknown person or group of people using the name Satoshi Nakamoto. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services.

Bitcoin has been criticized for its use in illegal transactions, the large amount of electricity and thus carbon footprint used by mining, price volatility , and thefts from exchanges. Some investors and economists have characterized it as a speculative bubble at various times. Others have used it as an investment, although several regulatory agencies have issued investor alerts about bitcoin.

The word bitcoin was defined in a white paper published on 31 October The unit of account of the bitcoin system is the bitcoin. The bitcoin blockchain is a public ledger that records bitcoin transactions. A network of communicating nodes running bitcoin software maintains the blockchain. Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes.

To achieve independent verification of the chain of ownership each network node stores its own copy of the blockchain. This allows bitcoin software to determine when a particular bitcoin was spent, which is needed to prevent double-spending. A conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, but the blockchain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions.

Individual blocks, public addresses and transactions within blocks can be examined using a blockchain explorer. Transactions are defined using a Forth -like scripting language.

When a user sends bitcoins, the user designates each address and the amount of bitcoin being sent to that address in an output. To prevent double spending, each input must refer to a previous unspent output in the blockchain. Since transactions can have multiple outputs, users can send bitcoins to multiple recipients in one transaction.

As in a cash transaction, the sum of inputs coins used to pay can exceed the intended sum of payments. In such a case, an additional output is used, returning the change back to the payer. Though transaction fees are optional, miners can choose which transactions to process and prioritize those that pay higher fees. The size of transactions is dependent on the number of inputs used to create the transaction, and the number of outputs.

The blocks in the blockchain were originally limited to 32 megabytes in size. The block size limit of one megabyte was introduced by Satoshi Nakamoto in Eventually the block size limit of one megabyte created problems for transaction processing, such as increasing transaction fees and delayed processing of transactions. In the blockchain, bitcoins are registered to bitcoin addresses.

Creating a bitcoin address requires nothing more than picking a random valid private key and computing the corresponding bitcoin address. This computation can be done in a split second. But the reverse, computing the private key of a given bitcoin address, is practically unfeasible. Moreover, the number of valid private keys is so vast that it is extremely unlikely someone will compute a key-pair that is already in use and has funds.

The vast number of valid private keys makes it unfeasible that brute force could be used to compromise a private key.

To be able to spend their bitcoins, the owner must know the corresponding private key and digitally sign the transaction. If the private key is lost, the bitcoin network will not recognize any other evidence of ownership; [28] the coins are then unusable, and effectively lost.

To ensure the security of bitcoins, the private key must be kept secret. Regarding ownership distribution, as of 16 March , 0. Mining is a record-keeping service done through the use of computer processing power. To be accepted by the rest of the network, a new block must contain a proof-of-work PoW.

By adjusting this difficulty target, the amount of work needed to generate a block can be changed. Every 2, blocks approximately 14 days given roughly 10 minutes per block , nodes deterministically adjust the difficulty target based on the recent rate of block generation, with the aim of keeping the average time between new blocks at ten minutes.

In this way the system automatically adapts to the total amount of mining power on the network. The proof-of-work system, alongside the chaining of blocks, makes modifications of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modifications of one block to be accepted. Computing power is often bundled together by a Mining pool to reduce variance in miner income.

Individual mining rigs often have to wait for long periods to confirm a block of transactions and receive payment. In a pool, all participating miners get paid every time a participating server solves a block. This payment depends on the amount of work an individual miner contributed to help find that block. The successful miner finding the new block is allowed by the rest of the network to collect for themselves all transaction fees from transactions they included in the block, as well as a pre-determined reward of newly created bitcoins.

The bitcoin protocol specifies that the reward for adding a block will be reduced by half every , blocks approximately every four years. Eventually, the reward will round down to zero, and the limit of 21 million bitcoins [h] will be reached c.

Bitcoin is decentralized thus: [7]. Conversely, researchers have pointed out at a "trend towards centralization". Although bitcoin can be sent directly from user to user, in practice intermediaries are widely used. The pool has voluntarily capped their hashing power at According to researchers, other parts of the ecosystem are also "controlled by a small set of entities", notably the maintenance of the client software, online wallets and simplified payment verification SPV clients.

Bitcoin is pseudonymous , meaning that funds are not tied to real-world entities but rather bitcoin addresses. Owners of bitcoin addresses are not explicitly identified, but all transactions on the blockchain are public. In addition, transactions can be linked to individuals and companies through "idioms of use" e. Wallets and similar software technically handle all bitcoins as equivalent, establishing the basic level of fungibility.

Researchers have pointed out that the history of each bitcoin is registered and publicly available in the blockchain ledger, and that some users may refuse to accept bitcoins coming from controversial transactions, which would harm bitcoin's fungibility. Gox froze accounts of users who deposited bitcoins that were known to have just been stolen.

A wallet stores the information necessary to transact bitcoins. While wallets are often described as a place to hold [62] or store bitcoins, due to the nature of the system, bitcoins are inseparable from the blockchain transaction ledger. A wallet is more correctly defined as something that "stores the digital credentials for your bitcoin holdings" and allows one to access and spend them. The first wallet program, simply named Bitcoin , and sometimes referred to as the Satoshi client , was released in by Satoshi Nakamoto as open-source software.

There are several modes which wallets can operate in. They have an inverse relationship with regards to trustlessness and computational requirements. Third-party internet services called online wallets or webwallets offer similar functionality but may be easier to use. In this case, credentials to access funds are stored with the online wallet provider rather than on the user's hardware. A malicious provider or a breach in server security may cause entrusted bitcoins to be stolen.

An example of such a security breach occurred with Mt. Gox in Wallet software is targeted by hackers because of the lucrative potential for stealing bitcoins. A hardware wallet is a computer peripheral that signs transactions as requested by the user. These devices store private keys and carry out signing and encryption internally, [73] and do not share any sensitive information with the host computer except already signed and thus unalterable transactions.

The user sets a passcode when setting up a hardware wallet. A paper wallet is created with a keypair generated on a computer with no internet connection ; the private key is written or printed onto the paper [i] and then erased from the computer. Physical wallets can also take the form of metal token coins [76] with a private key accessible under a security hologram in a recess struck on the reverse side. The domain name bitcoin. On 3 January , the bitcoin network was created when Nakamoto mined the starting block of the chain, known as the genesis block.

The receiver of the first bitcoin transaction was Hal Finney , who had created the first reusable proof-of-work system RPoW in Blockchain analysts estimate that Nakamoto had mined about one million bitcoins [95] before disappearing in when he handed the network alert key and control of the code repository over to Gavin Andresen.

Andresen later became lead developer at the Bitcoin Foundation. This left opportunity for controversy to develop over the future development path of bitcoin, in contrast to the perceived authority of Nakamoto's contributions.

After early " proof-of-concept " transactions, the first major users of bitcoin were black markets , such as Silk Road. During its 30 months of existence, beginning in February , Silk Road exclusively accepted bitcoins as payment, transacting 9. The Bitcoin Foundation was founded in September to promote bitcoin's development and uptake. On 1 November , the reference implementation Bitcoin-Qt version 0.

It introduced a front end that used the Qt user interface toolkit. Developers switched to LevelDB in release 0. The fork was resolved shortly afterwards. From version 0. Transaction fees were reduced again by a factor of ten as a means to encourage microtransactions. Version 0. In March the blockchain temporarily split into two independent chains with different rules due to a bug in version 0. The two blockchains operated simultaneously for six hours, each with its own version of the transaction history from the moment of the split.

Normal operation was restored when the majority of the network downgraded to version 0. As a result, this blockchain became the longest chain and could be accepted by all participants, regardless of their bitcoin software version. The US Financial Crimes Enforcement Network FinCEN established regulatory guidelines for "decentralized virtual currencies" such as bitcoin, classifying American bitcoin miners who sell their generated bitcoins as Money Service Businesses MSBs , that are subject to registration or other legal obligations.

What's the difference between blockchain and Bitcoin?

Blockchain is the technology that underpins the cryptocurrency Bitcoin, but Bitcoin is not the only version of a blockchain distributed ledger system in the market. There are several other cryptocurrencies with their own blockchain and distributed ledger architectures. Meanwhile, the decentralisation of the technology has also led to several schisms or forks within the Bitcoin network, creating offshoots of the ledger where some miners use a blockchain with one set of rules, and others use a blockchain with another set of rules. With smaller networks, these cryptocurrency blockchains are more vulnerable to hacking attacks , one of which befell Bitcoin Gold in Understand how Facebook leveraged specific aspects of blockchain technology to launch a new cyrptocurrency called Libra, and its potential impact on the banking and finance sector. In late , around the time of the financial crisis, a ground-breaking post appeared on a little-known internet forum entitled Bitcoin: A peer-to-peer electronic cash system.
